Yeah, I stopped watching at the 1:59 mark. You were up in the attic, you had your hole saw; how hard would it have been to drill...I dunno...DOWN. Even if you only drilled through with the pilot bit, then drilled the rest from the stall. Sorry, mate; no sub from me. Cheers.

Thanks for the video; it was really helpful. Does the fan have a timer that can be set to a specific running time?

[@RB-xg2vz]

One tip I picked up for CRJ Electrical channel is to put rubber grommets (the type you use in metal back boxes) under the 4 mounting points of the fan and then screw the fan down - reduces vibration noise.

[@TheDIYGuy1]

Sounds like a great tip that and something I’ve never done 👍

[@freddieleethompson3536]

I do the same but use tap washers.

[@kuk3411]

You can also take two pieces of ply screw the first to a joist and attach the second on top with beaded silicone lowers the amount of vibrations through to the joist

It's almost like you know what I need to do in our house! 🤣 Another brilliant and easy to follow guide. Thank you DIY King 👑

[@Participant616]

I screw these fans through cheap gardeners' kneeling pads, about £5 a pop from Amazon.

[@alanantliff3515]

Clear, excellent video and diagrams. Installed the same fan. Used the same Manrose 100T fan but hung from roof truss, supposedly less noise. Going to change over the one metre PVC flexi duct coming from fan to gable wall due to condensation in the duct during winter. After i installed it i asked my electrician to wire the fan separate to the light as originally fan came on with light, which was a pain when using the shower during the day, and the light was on! Much better now with the fan and light separate!

[@ppeaster]

I used this video to finally replace our rubbish noisy old fan with the Manrose inline model you fitted. Really happy with it - much more powerful and so quiet. Thanks for giving me the impetus to get it done as it's been annoying me for years.

[@TheDIYGuy1]

Glad to have helped out!

Found this in my feed literally two minutes after my new Manrose fan was delivered... Google knows me too well! 😆 Some info on condensation traps would be great, but very comprehensive video, great job!

[@FatherJHackett]

I've had the same fan since we bought our house 7 years ago. It's in the attic... in the box it came in, yet to be installed. Maybe after watching this, I'll finally install the bloody thing! 😂

[@lifter98]

Same here, only - 4-yrs though..

[@chrissyp7433]

Same here 1yr just have to wire it in now.

[@jeremycarr6915]

That is how it is done. My cowboy has the ducting at a 45 degree angle and no condensation trap. Oh, and no fan isolator as the job was done about 10 years ago. Time to get a professional in- great to have someone with a pride in their job to show what excellence looks like.

[@mikeevans9062]

Further to my previous comment. We never used the soffits again. We found roof tile vents much better as the ducting worked better being as short as possible and going in a vertical direction. I do like your use of insulation around the duct that will help with condensation in the duct where it lyes flat on the joists.

[@haddenhamvillagesociety8415]

Others may have already pointed this out but many soffits on older properties were created with asbestos boards - you need to be much more protected with a high performance PPE respirator before cutting the aperture - especially when doing so from below.

[@DTech101]

I always use ridged pipe stops turbulence and the build up mould in the duct. You said hard to find a fan with that extraction rate but for my downstairs bathroom fan installed over the shower area ridged ducting under the floor board this is the answer Airflow iCON60 Circular Extractor Fan for Large Bathroom, Utility Room or Kitchen 280mhr/78 ls but it’s a beast! PS I would get a humidity sensor wired up they do one that will work with that fan works good 👍🏾

[@TrickyTree84]

Ok used rigid tubes and they are so much louder I defo do not recommend it. Fan noise and noise from outside

[@DTech101]

@@TrickyTree84 louder maybe more airflow definitely I just suppressed the noise with slabs of rockwool, as extraction rate is what is really needed.

[@TrickyTree84]

@@DTech101 I found the fan itself louder though as the sound resonance in the tubes is greater and sound more easily carries in from outside.weapping in rockwool won't stop that. Yes more air flow but not worth it in my experience.

[@jeffjeffjeff2]

Fitted one of these manrose fans a couple of years ago and it's so much better than the small inline fan type as you say. My only regret is not upgrading the ducting at the same time to the insulated type. I'll have to get a handyman to do it now as access is so poor into my eaves.

Thanks for the vid..... I've just had my new extractor fitted used solid tubing with a slight fall to the outside vent to drain any condensation to the outside, also added rubber grommets under the fan to minimise vibration, plus removed the flyscreen to prevent build up of fluff/dust and added a backdraught flap which keeps the bathroom draught-free especially in winter.

These fans need fusing down which I did via a spur with a 3a fuse, I didn’t realise that you could get a fused isolator. Live and learn. Great video

[@youthfulrider407]

Just a tip for the less powerful fans, with the duct work I would always recommend using solid ductwork as opposed to flexi. Better air flow, less resistance, less dirt and bacteria captured over time, Also undercut the door to allow make up air.

[@TheDIYGuy1]

👍 thanks for sharing

[@willwoodvine143]

I installed the Timer version of the Manrose fan over the shower and also have an always on version (set to lowest speed) in the main part of the bathroom. Did this late last year and we've had no issues with condesnation, mould or "lingering smells" :) Must admit I'm surprised at how quiet these fans are, no need for anti-vibration measures at all.

[@danlux4954]

Is the fan rated for always on?

[@lenrichardson7349]

That wiring model was very helpful to understanding what people have done before, so even if I don't do anything I know what might be needed.

[@kevinthegerman1]

Excellent video, thanks for doing this. Though I'll be okay through having taken notes, a downloadable/printable wiring diagram would be so helpful for when I'm up in the loft etc, when you just want a printout to make sure you're doing it right.

[@DaxMayarex]

I subbed for that demo piece that you made, great teaching aid... I'd have really liked it if you had shown wiring up the dummy, would make for a great short video that people could follow along to.

[@simonbeasley989]

I fitted one a few years ago, those fans are brilliant. The bathroom had mould when I bought it as the builders in 2005 fitted a pathetic mains fan in the ceiling nowhere near the shower and bodged the ducting and I swear it couldn't hold a sheet of toilet paper up because I tried it! The Manrose can hold a flattened toilet roll middle up! And instead of motor vibration the main noise is the rather more pleasant whoosh of airflow.

[@TheDIYGuy1]

Absolutely 👍

[@patrykgorecki581]

Works quite loud....Great video!

[@RogerHolden]

I've installed one of these, but only after first buying the version without a timer - so be aware that that exists. It didn't even cross my mind that they wouldn't have a timer, thus didn't check the spec, like you wouldn't check the spec of a car to check it has a steering wheel! Screwfix brilliant as ever and exchanged it for the (more expensive) timer version. I've also turned mine down to the lowest power setting as thats fine, and it was surprisingly noisy on medium or high.

Really good extractor, I put one in the shower room of my grandad annex. Gonna use the same for my new bathroom and en-suite.

[@mikeevans9062]

Many years ago I installed a kitchen extractor vent in a soffit as you have done. It was a new build and we had a building control officer come and inspect he wasn’t happy and said it contravened building regs as the moist air would have detrimental effect on the soffits and fascia. I don’t think I’ve seen this extraction position on any new builds.

[@stuartday1876]

Just used the exact same fan for our bathroom, the performance is amazing. I used solid pipe from the fan out through the gable end, just because I worried about moisture pooling inside a long flexi pipe. I have a small drop on the solid pipe, so it's all downhill to the gable vent.

[@stuartday1876]

P.S. the electrics blow my mind, but luckily I have a brother in law who is a sparks who broke it down into simple instructions😂

[@TheDIYGuy1]

Yeah if you’ve a long run it was probably the best way 👍. Nice work

[@dougle03]

Now I know the manual shows flexible ducting but.... Air ducting is always better when the inside of the duct is smooth. For such a short run I'd have been using 4" tube with an insulated wrapper. the rough surface in flexible ducting slows down the air travel, it causes turbulence and reduces the efficiencies of the fan. Perhaps not a problem for this install since it's a short run, but worth using a couple of lengths of tube between flexible angle joints. Cracking video, and I could feel your pain filming in that heat... 👍👍

[@flyingwhiteindian]

I dont understand why the tube has to be insulated - isnt it just taking the air outside. What does the insulation achieve/

[@dougle03]

@@flyingwhiteindian In the winter if the duct was not insulated it would get very cold and the steam would condensate in the duct before getting outside which is not desirable.

[@narrowboatlongpod4176]

@@flyingwhiteindian Condensation forms and runs back inside. You can get traps to take this away but it's not usually practical.

[@towkukus]

what air ducting would you recommend??

[@simonbriggs6332]

I’ve just swapped an in ceiling style fan which just wasn’t clearing the bathroom of steam with 1 of these style in extractor fans. Doesn’t seem to have made much difference at all even though it’s got almost 3x airflow rate. Whilst I was upgrading the fan I also used solid pipe from the intake vent in ceiling to the fan itself (flexi ducting from the fan exhaust out to the eaves vent as that’s difficult to get to)

[@rss112]

Top video mate! Just what i was looking for! Might of been worth adding that the door for the bathroom should be cut back to allow air flow. But over all great video. I will be installing one of these in the summer.

[@MrBinabanana]

Great video, but one little thing worth mentioning is that any electrical requirement in the installation instructions for any accessory need to be adhered to in order for the installation to be compliant with wiring regulations, and most of these shower fans call for 3A fusing on both the permanent and live cores - so the usual 6A MCB for the lighting radial isn't sufficient for compliance. I usually install a separate single backbox next to the isolator with a 2-way grid plate containing two fuse holders fitted with 3A fuses. It's an added expense and arguably overkill, but technically needs to be done in order to make the installation 100% compliant.

[@Dr.Stacker]

That seems like a lot of wires and 3x back boxes (inc the light switch). Could you instead have a 3a fused DP FCU somewhere in the loft next to the fan? Thanks

The Manrose MF100T instructions state it must be fitted to a circuit with a 3A fuse. 18th edition states manufacturer's instructions are taken into account for electrical installation. I use a double pole fused spur as the isolator with a 3A fuse fitted and a double pole light switch so the lighting circuit and extractor circuit are switched separately when installing these.

I’m not sure why this is as to me it’s a bit pointless but 90% of manufacturers state that it has to be there in the installation guid. Please don’t think I’m being a keyboard warrior as that was a cracking install you did there just a point I picked up that’s all.

[@ef7480]

An observation- the Wago 221 connectors should be used with the Wago 221-4 junction box with the 3 compartments to be maintenance free (although yours is accessible in the loftspace). The Wago box with the 2 compartments at the end like yours is for the 772 and 333 connectors for a maintenance free connection, just in case someone uses the wrong combination and hides it under floorboards or in a wall. The 2 compartment box can be converted to MF with inserts from Wago👍

[@shmink2]

The internal plastic of the ducting I personally like to electrical tape that onto the fan and vents. It gets a nice air tight seal and then I'll push the rest of the ducting over that (insulation and out sheet) and then zip tie that to just minimise it moving.

[@David-dz8jb]

I recently fitted a inline bathroom fan and fused it down to 3a as per manufacturers instructions (this is their get out clause in case of problems) you could make up a multi gang switch plate to fuse both line and switch line together with a three pole isolater but it gets a bit over the top and messy. The best solution I found was fit a smart switch cheap as chips which is linked to Alexa and I find this the very best for complete control over overrun I just ask Alexa to switch on the fan and on it goes for 20 minutes you can alter the settings by just asking Alexa “ turn on fan for xx minutes” and of course you don’t need to have the fan running at all for a trip to the loo at 3am. Probably not the best solution for a enclosed bathroom where I would guess a light linked fan would be required but in my situation this works the best.

[@johnadams1976]

@@David-dz8jb In the end I bought this fan.... which is connected to the isolator of the old one.... inline I put a Sonoff Basic R2, which I flashed with Tasmota for 100% local control.

An automation is triggered if the bathroom humidity sensor is 8% higher than the one in the hall (i.e. someone is using the shower!!!) the fan automatically comes on until the humidity sensor in the bathroom is within 3% of the one in the hall. Works absolutely perfectly. I'm also putting a Zigbee button in the bathroom to press if you want a 3 minute fan extraction - i.e. you've done a poo!!!!!! LOL!!!!

Nice video and very well explained regarding the wiring. I'm sure I read somewhere that you shouldn't put extractor fan inlets and smoke detectors in the corners of rooms due to how air flows in a room.

[@TheDIYGuy1]

👍 thanks, never had a problem myself with this position but I’d like to hear if anyone has.

[@idi0tdetectioninprogress]

Smoke detection should be 1M in from walls where possible and installed flat, as smoke rolls. Extract ventilation is sited more source specific, like over baths/toilets, in front of cooking areas etc.

[@gwarski]

By putting the valve in the corner you do restrict the air flow, however in this scenario the difference would be negligible

[@Polyhive]

What I would like advice on is where to source the outside vent with a one way flap that does not rattle in a wind??

[@Joshoptimuscrime]

I bought a MF100T a few weeks ago. It’s running at its maximum speed, the fan has approximately 400mm of duct either side, venting out of the gable end with a wind flap vent. The vent is directly over the shower (rainfall type) The suction is unbelievable I must admit however the bathroom is still very foggy when showering and moisture is still dripping from the ceiling, walls are still wet after a shower. I don’t know what more I can do, very annoying. I may install another fan but on the external wall and see if that helps.

[@BarrrySpiers]

I’ve just replaced our manrose MF100T after 7 years of use (it died gradually getting slower and slower and yes it was cleaned annually). They are great, quiet extractors, however, having tried all sorts of ducting the wind noise in our small ensuite is very loud. I would be interested in any advice to limit this noise, my 2 thoughts are: 1. Fit a different inlet grill in the ensuit, maybe a different design may cut down the wind noise? 2. Set the fan speed to med or low? However I love the volume of air this thing sucks out on high speed, it almost closes the door! 🤣 Grateful for any advice please…..👍

[@steve6375]

I use medium hard rubber spacer standoffs to mount the fan motor. It makes a massive difference to the noise because the board you screw it on acts as a sound board and amplifies the vibration. Easily available from Amazon, etc. Don't know why Manrose don't supply them in the first place!

[@Hypnot47]

I'm analising the possibilty of adding one of these on a kitchen floor with a 150 mm tube going up to a kitchen island balcony. Do you think it would work upside down? sucking the fumes from cooking straight to the floor and outside my house, maximum 1 meter distance tube?

Absolutely brilliant video - thank you. About to do same myself. One thing I don't understand is why the chase out between the switch and the isolator? nothing seems to be running in the chase. I'm trying to work the runs out - am I right in thinking like the mock up; run everything up to the wago box in loft and run it out to fan and lights from there? I will need to do a chase like you to get the light swich cable into the loft but will it just go through the isolator switch back box but just using this as a path and making no connections here? Thank you so much again - great channel, Best wishes, James
