- HOW TO CHARGE REFRIGERANT WITHOUT DIFFUSING ANYTHING IN THE ENVIRONMENT
I had a low level of refrigerant in one of my reefers onboard. I did a leak test and could not find any source of leak so I have decided to charge refrigerant on it.
There is a specific way on how to properly charge the system with refrigerant without polluting our environment. It is a must to follow the correct procedure in charging the refrigeration system.

Free knowledge from a world class seafarer. I hope your channel will be discovered more. You deserve all the commendation. thank you very much for the knowledge.
Thank you very much. Comments like this is enough to keep me going.
Hi Jake great video. Very well explained.That was a trip down memory Lane for me! I was an engineer officer cadet in 1982 and later became a HVAC engineer.
Leckyjake is a world class Filipino ETO no doubt.
Very much appreciated. Thank you for your wonderful comment
Yes no doubt I am Pakistani ETO.... Love and respect for sir Leckyjake from Pakistan
you are just different ,thank you for the knowledge you gave us. you just make it easy to understand. thank you again
I started to watch your videos and they are instructive sooo much. Thanks for sharing your knowledge with us.
Always appreciate the refresher course! Please keep em coming friend. SF ILWU
Great video and thanks a lot. It will be perfect to slag and tight the gland packing while handling the valves and do leak test again before leaving.
Thank you for the clear, easy to understand presentation.
thank you for watching
I helped change an evaporator in a walk in fridge today with one of our fgas techs. The gas charging operation was similar to yours but we had scales. He also had a funky ratchet spanner for the valves. As a 25 year electrician this was something different. I am doing my City and Guild’s fgas next week so I can play with the AC units at work. As always good videos. Best wishes.
Thank you and good luck to your next week's job
@@leckyjake what brand of pressure manifold ur using or those connectors, send me link I need to buy
Thank you
Galing nmn po salamat sayo sir sa mga vedios mo na marami talaga mapupulot na dagdag kaalaman God bless po😇

salamat lods
Thank you sir
Hello sir
Great job please continue to share knowledge.
I have a question
Do you get paid extra to maintain refeer or any repairs you carry out on reefers?
Thanks,..
Bravo sir🙃
thanks
Smart Boi
You can Join us, we need good people
I really like what you have shared with Us kindly during charging gas was compressor running or not because I can see from low side was still zero
Good video.I have 1 question,during fillng up system th red valve on manifold should be open also and we can see how is pressure growing up?it was not so clear for me.
I want to work with You're good teacher
Hi my friend Leckyjake, I'm speaking from Brazil, I'm trying to find out about the Alj281 from the Daikin container.. Other than the SMV valve, the SMV coil, and the solenoid coils, what else can cause this alarm?
okay you did diffuse some air,ref to atmosphere, i have heard of recovery bottle to purge out any gas from the system. please make a video using that.
hi iam a new member INDIKA
Love u lots ❤❤❤
good job sir
Thank you
I told you brother...you are a great teacher...thank you and God bless you.
How to Use the vacuum pump and take out refrigerant from the system. Can you please make a video on that also.
Sir , it is very impressive. I have a doubt that wen u removed the discharge side hose after filling up the refrigerant why did u make the service valve of discharge side from midseat to backseat(open) . It shud be front seated after charging
Very impressive that you do both electrical and HVAC! Who is responsible for paying for this type of repair, the owner of the container, the shipper, or is it covered by the boat as the cost of doing business?
i am just being paid as per monthly salary.
I have the same question really I think he means who ends up paying for the parts and refrigerant needed when a unit goes down while at sea is it the cargo transporter or the shipper or the receiver
@@TH-camviolatesmy1stamendment i think he has to write a report for each box repaired and shiping line is going to pay for the serviced container as per report.
sir, we all know in refer system from evaporator slightly super heated vapour returns directly to compressor crankcase, not directly to the compressor suction side. from the crankcase compressor takes suction.
why is that so?
is it to eliminate risk of liquid refrigerant getting directly into the suction? or any other specific reasons?
can you pls help?
Greetings. What about purging air from the red/blue hoses and the centre of the manifold? Thank you
You don't need to purge as they are always isolated. It means that below zero pressure discharge gauge (red) will keep on that position.
How do you know the required suction and discharged pressures of the system??
Hi sir. I just have some friendly questions and observations:
1.) As you mentioned that the system is a closed one, the diminished system pressure should surely imply a leak somewhere in the system. Were you able to find it?
2.) While you did purge the air out from the yellow hose but I did not see you purging out the air from the blue and red hoses. I haven't experienced working on a refrigerator yet so it really wonders me how to purge the air out from the blue hose considering it's below or equal to atmospheric pressure unlike in air-conditioning system where low side pressure is considerably above atmospheric.
Hope you could enlighten me sir. More power to your channel.
Sir is it normal that the suction line is theres no presure only the discharge line?or maybe only for that system we can check presure on discharge line thanks for info.
👍👍🎯
When you connected to the low side service port, there was a lot of moisture and water droplets present. Should you have wiped off the water with a paper towel first so that water won't get into the system? Thanks, Lecky! God bless you!
There’s always going to be a little contamination. The filter drier will take care of it.
What type of leak detector has been used?
Hello sir. During charging suction and discharge valve is open?
How many rotate the service valve open , fully open or just a little bit.
Because I see you open the service valve just a little bit. ,Just make sure 🙏🏿
Thanks sir
Sir yung valve po ba ng suction line fully open o half lng?salamat po sir
Hello, good video for begginers, but where is scale for refrigerant bottle, this is especially need for people who is learning this.
It”s good to now how many kg you get in to the system.
I always depend on the working pressure as the ship is moving from places to places, different ambient temperatures which might affect the operation of the refrigeration system.
@@leckyjake, yep this is also correct, for expirience people who now this.
Any way thanks for videos, good job!
@@leckyjakehow do you know what is correct working pressure?
Why is the suction gauge pressure reading 0 which the unit is running?
I would like to ask, during charging does the compressor is running that time?
Yes it is running
@@leckyjake so it means, during charging you just to wait to run the compressor before opening the manifold valve?
@@benjiebajuyo9462 since the temperature is way above the set point, the compressor is continuously running.
@@mlenstra yes your right thank you for the response I just realized it just now hehe.
Sir jake asko ko lng po new lng po sa reefer daikin alarm f603 how to fix thank you more power pagpalin po tyo ng may kapal
incorrect container model setting yan
anung number ng ratchet gamit mo pag open ng service vlv sir
Sir, ask po ako kung ilan po ba ang normal pressure ng freon sa provisionn compressor at Ac compressor? Thanks and god bless sir.
Ano kaya problem sa cv namin, as checker of reefer diko po alam kung paano ayosin pero gusto ko lang matotoo. Myproblema kasi yung reefer namin first issue ayaw mag andar ng fan on going cool kaso nasa positive 30 lang tapos dibumababa. ang set point is -25 after 5 to 10 nag heat tas defrost. Check ko yung maleplug ok naman at yung wiring at voltage ng container ok naman. Ano po kaya problema or ano dapat gawain po. Newbie lang po ako totally checker po ako sa reefee namin
Hi sir
So where did the refrigerant which was in the system disappear to before charging since you said there was no leakage ? And also when you finished charging the low side gauge was still showing zero
please take note that the container is moving from country to country, ship to ship, and port to port in which a lot of Technicians are handling them. there are some instances that they do maintenance and troubleshooting in which they might have had charge refrigerant less esp if they are in a very low ambient temperature.
Thoroughly leak check as what you’ve said on 1:37, but you didn’t show that you check the tubings on condenser, evaporator and bulkheads leading in/out the evaporator. So how is it so sure that the system has no leak at all? And how is it that the suction/low pressure side is still zero after charging? Thanks if you can be able to answer.
if i will put the whole clips then the video will take for hours. This is a moving machinery which travels all around the world, from trucks to trucks, from cities to cities, vessels to vessels and from hot area to low ambient temperature area. if the container came from a low ambient area and a service was made then there is a posibility that less refrigerant was charged but would still work since condensation on the condenser is too easy due to low ambient but once this travels to tropical countries just like malaysia, then this less freon would matter and need recharging.
Thanks for the explanation 👍
Bravo
Diba liquid state yung nasa red connection?
hello lucky
how to become an electrician on board.?
My friend ,coloca uma legenda em português pra nós compreendermos blz
Hello brother, normally the system is working in chiller Mode . I can change to freezer Mode
Like if I change the temperature -18 , what I will follow?
Also Another Unit ( Carrier Thinline ) Modulation valve doesn't Open Fully , like it's Open only 17 , How I resolve that problem
So there is no leak?
Sir ask ko lng po bakit po zero ung value ng low side?
You're at a real disadvantage when checking for leaks since you can't get on the inside
especially underneath the evaporator
Sir, clarify ko lang po, umaandar po ba ang compressor pagmagchacharge??
sir, since u didn't find any leakage in the system, then why refrigerant level was low? cz we all know this is a close loop system, nothing comes in and out
i cannot see any source but it could be on the last service by other tech which might mistakenly charged less refrigerant
Does it mean that at the time of your troubleshooting, the reefer container had just been loaded?
Sometimes it is better to put bottle bottom up to charge liquid refrigerant.
id rather wait for the process while charging vapor in the suction side
Where you will charge the liquid refrigerant to the system if you want to charge the system by liquid rfrgnt. I'm asking the foreigner Sir lecky.
sir lecky jake solid fan here . question lang po. pag nag charge ba ng refregerant dapat ba naka andar ang compressor or naka para ang compressor.
running ang compressor
@@leckyjake thankyou for the prompt answer sir. So, can we do (charging refrigerant ) on our provision reefer and HVAC onboard vessel given the system is running? because the video you shared is for reefer container . And also, i am confused on one person i asked he told me he charged refrigerant na naka para ang system. Thankyou sir idol . Answer is highly appreciated po.
charging of refrigerant, for me mas ok na running ang system para hindi nabibigla yung suction side ng system dahil continous running at circulation ng refrigerant and to add up, madali siyang papasukin sa system lalo kung vapor state na yung nasa tank at sa suction ka mag connect.
same lang hvac and provision
@@leckyjake very well explained po sir idol, and this will add my knowledge on handling hvac onboard. . looking forward for more videos regarding wiring diagram interpretation .thankyou sir.
ps. i followed you on IG
Why that blue line i.e suction line was showing zero psi
because it it the suction line, it is normally into that range if your setpoint is deep freeze
500 a day to sa oil&gas hehehehe
Condenser coil leaking :D
i can say no, because it's been a week now and unit is still running good and pressure is holding at 9.5 bar pressure
@@leckyjake i might be wrong ;) but most of these units have issues with condenser coil
Pinoy po ba kayu sir
what country are you from? are those charge hose fittings required by your countries laws? how do you push air from your hoses with those silly low loss fittings? hope you don’t have to pull vacuum through all that silly stuff also. we can and are made to always contain our refrigerant as techs and you here prove it’s easy to do, yet it commonly leaks from refrigerant systems with little or no regulations or punishments when it does. brand new equipment leaking its charge from day one. i’ve seen 100’s of kilos of refrigerant go freely, but it’s not made a big deal. but your using a manifold thats overly complex, expensive and burdensome i’m assuming because it’s required by your laws. let’s try building equipment that’s not junk
“Complex and burdensome” in which way(s)? This looks to me like a perfectly standard HVAC manifold set with some automotive QD fittings to connect to the service ports, which parts would you say are unnecessary?
@@mlenstra look like low loss fittings to me
dont teach people how to recharge, its ONLY TO BE DONE BY PROFESSIONALS
Just make decisions to my life
how to mnow which is suction vs discharge
and where did you read 8.6 par
Hi Mr Lecky please can you share your email address so I can discuss some questions I have about reefer repairs. Thank you for your good videos
