I get it, we are all in this together to some degree, but if that manager goes on vacation, do you know? My guess is no, you don't. Now, with that said, I will still take into consideration, and have given a discount, or reduced cost, but that is my choice.

[@ratchet1freak]

that secondary valve you removed ir actually handy to replace the dryer, the king valve and secondary liquid line valve isolate the dryer which means you can replace it and I believe also has a port into the isolated point area which even lets you evacuate before opening the valves again.

[@jman0870]

I would actually install isolation ball valves with ports around driers on large systems if they didn't exist so that I could replace a carbon core drier with a standard drier without pulling the charge. It is such a time saver for burnout cleanups on large systems!

[@De4thHunter117]

Here in europe we use a 2 to 3 bar difference for fan switching. So 29 to 43 psi. You look up the pressure for 42°C condensation and use that as cut in for 1 fan and like 45°C for a 2nd fan

[@youdontknowme5969]

[@Tokaisho1]

Really nice solution with the two fan cycles

[@primetime758]

see Chris this is where we differ the fan cycle control is suppose to be on the liquid line 1. Discharge is always higher 2.i want to control the pressure after the freon has circulated through the condenser. 3 to change anything simply close the reciever

[@jasonjohnsonHVAC]

Not long ago i put fan cycling on a RTU for a server room for low ambient cooling. Had a 3 phase condenser fan motor. I set up everything correctly to maintain a 90° saturation and keep the evap from freezing up. Still the fan was on off on off constantly. Customer didn't want to pay for an economizer. Their maintenance guy was on the roof and watching the fan bang on off. He calls me and asks if that was good for the motor......i said no, but that is what you wanted to pay for. He didn't like it, neither did i. They ended up paying for an economizer to be installed. Lol.

[@chap3845]

Leave the 2nd liquid fitting next time. Just makes it really easy to check pressure drop across the drier.

[@jeffreykubiak5126]

Nice Chris its all about the solid column of liquid to the expansion valve! I like how you left a open port for backup on discharge! For future use! Going to rewatch on importance of lead and lag condenser fan operation. Got my field piece probes haven't used them yet. Hopefully back to work soon? Measure quick !

[@ElmerCat]

Another thought, considering the service call was triggered by a dirty condenser - suppose the fan control could also reverse direction cyclically and/or periodically. Might this help to keep the condenser clean by blowing out dirt and debris from the other side, each time it changes airflow direction?

[@lactosis--undefined]

[@giorgosktoridis903]

Now when the filter dryer gets restricted he needs to evacuate the evaporator and lines.if there was no access valve just add one between the two king valves. How much would that cost more?

Every Morning I take a walk around the restaurant and make a note of anything wrong. A few minutes of checks can save you a world of hurt.

[@jman0870]

I almost got myself into trouble once by trying to cycle fans independently. You have to be very careful that the second fan doesn't spin backwards with only one fan running because PSC motor torque sucks and will actually start backwards if it's torque isn't enough to stop the motor and reverse the rotation. Typically it's not an issue if each fan has it's own venturi it sits in. My experience was on a 7.5 ton York split and the props don't have venturis because York sucks.

Couple thoughts, did you consider just installing a headmaster instead of the fan cycling controls? Receiver looks generally large enough. Also with pipe insulation outside, I’m starting to wonder why it’s the norm for it to be unprotected/uncovered. It obviously gets just trashed from being in the elements. I feel like it should be typical to cover, like with the white plastic cover for instance.

[@Bryan-Hensley]

Looks like dual fan controls would make it very inefficient because with only one fan running it's going to pull most of the air though the fan that's not running instead of through the condenser. Wasting fan energy.

[@HVACRVIDEOS]

Nah it's got a baffle in between the fans

[@FishFind3000]

For tne commercial own chains have it figured in their budget every year for yearly or monthly cleaningsand inspections. Also they are quick to approve big repairs.

With them it's always why can't you fix it now, when we have told them for a long time it is going to fail. Small business always have excuses and always pay late

On the high pressure protection, I think some standards association don't allow shrader under the protection since it can "fail" where the depressor slips next to the valve and essential renders the high pressure protect useless. This isn't the same on fan cycling/low pressure as those protect the equipment from breaking down as opposed to the high pressure which is a safety concern.

[@davidwyatt4845]

It is a UL requirement that the high pressure safety cannot be “valved” off.

[@semidvdcdt8433]

That's really good to know. I often see hoses with depressor on rack without Shrader... And the depressor break and block the control from reading. And that's factory on multisystem parrallel rack.

Was the evacuation pump leaking at 8:18?

[@ElmerCat]

@ 21:24 - Is there an operational or efficiency advantage to having the fan closest to the inlet running more than the other fan? Surely, this will have a side-effect of causing that side of the condenser to get much dirtier than the other side. In addition, the fan motor would be expected to wear out sooner. Considering a dirty condenser is what triggered this service call, and to mitigate the cost of future fan motor replacement, would it be worthwhile to use a more advanced fan control which can alternate between fans to cycle them equally?

[@richardbartlett6932]

Hmmm The first thing to try would be just running one fan on the switch to cycle and see how that performed. If it really needed additional (which I doubt) control then a proper FSC should have been fitted to control both fans at the same time. IIRC these T should have a copper washer for them to avoid brass to brass . You've introduced additional leak points with these new connections especially using flares which are known to be the most likely point to leak on a system.. Worse they are on the discharge which is the pipe that suffers most expansion and contraction.

Do you cycle the furthest fan the most just for ease of service because that one will fail first? Or is it because of the temperature of the coil being warmer closer to the inlet so you want that fan running more?
