HOW TO ADD R404A REFRIGERANT INTO UPRIGHT FREEZER

[@makemaniachannel1354]

Good morning, congratulations on the channel. I wanted to ask you a question. I bought a used freezer cabinet and when I turned it on it worked strangely, the compressor turns on, stays on for a while and then turns off and doesn't reach temperature. To understand better I excluded the control unit and connected the compressor, evaporator fans and condenser directly to AC. Unfortunately the compressor continues to turn on and off. I noticed that the compressor's absorption while it is working (not at start-up) is 1100 watts, when according to the plate it should absorb 600 watts (the two fans together consume about 100 w). What could be the problem?

[@THEMULTISKILLEDTECH]

Check relay, overload, and run capacitor first, if still persist replace compressor. But before doing so check if there's a solenoid valve that runs together with compressor

Sir, thank you for your very informative video. May I ask your help. I have a 4 door upright freezer with R404 refrigerant. I changed the filter dryer and capillary. I have another access valve before the filter dryer. Is it ok to charge liquid R404a before the filter dryer side or vapour on the low side? Thank you and more power.

[@THEMULTISKILLEDTECH]

Try it sir since that procedures are discussed in our refrigeration books. In walk in freezer/chiller we charge liquid in low side the reason is refrigerant goes easily into the system.

[@joelbengco5344]

@@THEMULTISKILLEDTECH Thank you for the response sir. More power!

[@joshuarondero6105]

Hi good day sir Regarding on open Display meat chiller sa suction pressure same lang din po ba 25-40 psi and let be considered the ambient temperature of the area? Thank you in advance

[@THEMULTISKILLEDTECH]

Best practice sir is follow manufacturer's recommendations sa unit nila. Mga chart available online are guides lang natin. May unit kaming r404a na 45, 60, 40, 25, 16 psi ang karga . Ang gulo di po ba? As what im saying, follow the manufacturer's recommendations

[@jorgeLopez-xn9uy]

Great video. Question I have a freezer that calls for 24oz of r404a. Around what psi should a freezer be at.and do I need to charge in liquid or gas?

[@THEMULTISKILLEDTECH]

18 - 25 psi sir, and don't charge it in liquid unless your unit is walk in freezer and the compressor is between 5 -20 ton

[@jorgeLopez-xn9uy]

Thank you

[@jorgeLopez-xn9uy]

​@@THEMULTISKILLEDTECH thank you brother. Here an update I add the 24oz and it left me at 15psi the freezer got to the set temperature at -5 and shut down. I did notice a little frost built up once it hit -2° do you think I should add freon until it get to 18psi?

[@THEMULTISKILLEDTECH]

Use clamp meter too sir and try to reach the rated amps stated to the freezer label. Is your unit operated by digital control ?

[@jorgeLopez-xn9uy]

​@@THEMULTISKILLEDTECH yes it a digital thermostat. Meter is reading 6amps

[@Jay-r6c]

Sir yung chiller ng ice,umiinitvng husto ang compressor kaya nag ooff compressor saka yung cable nya galing outlet mainit din

[@THEMULTISKILLEDTECH]

Check condenser fan at condenser fins baka madumi na po. Yan po ang nag papainit sa compressor at ang isa pa ay baradong filter drier

[@wasimedoo7994]

My friend the best explaintion but i am working know on a coller like that one it was working with r134 freon on some one change it in to 404a compressor the system have a capillary i put in 25 to 30 psig of 404a an it not working the way it should can you give me some advice please god bless 👍

[@THEMULTISKILLEDTECH]

You should replace the compressor oil my friend

[@wasimedoo7994]

The compressor change 134a to 404a

[@wasiuadewale9781]

Thanks a lot for your video. I want to ask if I can charge r404 to r22 compressor after changing the txv to 404.

[@THEMULTISKILLEDTECH]

Yea sir can, just observe your txv. I've done that on our old walk in freeze lr w/o changing expansion valve and commercial refrigerator.

[@JoyAlonzo-n5c]

Hi good day sir sa walk in chiller bitzer anu po tamang suction pressure 35psi to 40 psi po ba? Thanks in advance

[@THEMULTISKILLEDTECH]

Mga bitzer namin sir is 20 psi lang, pero ginawang 30 ng mga kasama ko sir. Pero better contact mga supplier nyo for warranty purposes sir

[@GorosaurusEditz]

Sir pwdi ba mgVid ka mgRefill ng freon sa water dispenser?

[@THEMULTISKILLEDTECH]

Sir wala po kasi kaming water dispenser, pero watch ka ng video kung paano magkarga ng 134a sa ref, same po yan sa water dispenser. Charge mo ng 6 psi lang. Sa mga bago unit ay wala pa po yang access valve, need lagyan at hanapin ang leak kung naubos na freon nya sir.

[@tahiyya5913]

Hello I changed the compressor of open door freezer..I charged the gas 404a up to 20..But the temperature not reaching below 7°c ..I need below 0..Can you please tell the actual problem..And let me know the actual running pressure of refrigerant r404a

[@THEMULTISKILLEDTECH]

Can you tell me your setppint value in you digital control please?

Sir what is the problem of freezer compressor which has moisture/cold on the top of compressor. What is the solution?

[@THEMULTISKILLEDTECH]

Are having an ice built on evaporator? If no, then its normal reaction

[@chuanshan3582]

Hi Sir, if the refrigerator says R-404A 4lbs max, what psi should it be at? thank you!!!

[@gabdgraieb]

Use subcooling and superheat reading🎉

[@anatalioambosjr1792]

Hello sir, ask ko lang sana kung parehas lang ba ang karga ng 404a freon sa compressor na 1/2hp- 3/4hp, at 1 hp,at ilang psi charge sa low side ang minimum to maximum nya? Thanks

[@THEMULTISKILLEDTECH]

R404 between 20-25 psi lang sir for freezer. Pwede ka din magbase sa ampere sir, before ka magcharge check Muna run capacitor if less than 80% n ng value nya change na. If 1 HP change with 1 HP, if 3/4 HP, change with 3/4... Gaya ng sinabi ko sir base ka SA ampere at di ka maliligaw

[@THEMULTISKILLEDTECH]

R410A should always in liquid charging, but for R404A not at all. In big system like cold rooms it needs to be charge in liquid for the reason of easily charging. But for small units like 4 door freezer, chest freezer .....no need.

Sir I have a question. I have a refrigerator which is horizontal laying down with 3 doors in silver metallic body And in this gas is 404a I charged gas and its working good but becoming very hot after some and because of over load stops working Plzzz tell how much gas i should charge at how much amps so the compressor will not get hot any more and cooling also be good And I need temperature of that chiller from +1 to +3 range Plz

[@THEMULTISKILLEDTECH]

Is your 3door chiller still have label sir? If so, a refrigerant in kilograms is stated therein. Over charging makes your compressor overheat and the overload will cut off the power to protect it. In my description I write there our R404A charging pressure and our units are for commercial use.

Low pressure only go to 10 psi..thanks

[@THEMULTISKILLEDTECH]

Try to add more refrigerant sir, just pay attention to your compressor amperage

[@blingmotions6996]

Why didn't we use liquid from the 404a tank

[@THEMULTISKILLEDTECH]

Don't refill if compressor is running, compressor pumps vapor not liquid.

[@blingmotions6996]

So if it's a walkin freezer it could happen but a upright fridge no?

[@THEMULTISKILLEDTECH]

@@blingmotions6996 You can do liquid charging as long as compressor is in off mode. For both upright and cold room. Top up in walk in freezer using vapor is, it takes time ( R22, 234a .. vapor charging; R404a ... liquid charging) what ever freon you use, do it in liquid charging
