Charge the unit to the specified amount (See unit specifications or serial plate
for charge specifications per model).
---------------------------------------------------------------------------------------------------------------------------
Listed below are two variations to correctly charge the sealed system
Method 1- DIAL-A-CHARGE
Method 2- Weigh in Liquid on High Side
DIAL-A-CHARGE Method
Using a length of manifold hose, connect one end to the manifold, the other end to the
weighted charging cylinder.
Adjust cylinder to weigh in the correct amount of refrigerant into system based on nameplate
charge.
It is best to use low loss fittings on hoses to avoid loss of charge when removing hoses.
Purge air from cylinder hose to manifold by loosening cylinder hose at manifold and bleeding
liquid through hose to manifold.
Open manifold and charge unit.
Run unit for at least 10 minutes to confirm that the unit has a full frost pattern on the
evaporator and that the unit is not overcharged and there is no liquid returning back to the
compressor.
It is normal to have some condensation or slight frost on the suction line. Typically this will
occur towards the end of a run cycle. If the frost continues down the suction line to the
compressor, the system is overcharged.
Once the system is charged, clamp off the process tube downstream from the access valve.
Remove the valve, cut off the extra process tube with the piercing, fill the open end of the
process tube with solder. Remove the clamp from the process tube and leak check.
Vacuum Pump Tips:
1) Remember to change vacuum pump oil after evacuating a
contaminated system.
2) Frequent oil changes will increase the pumps potential to
achieve the best vacuum possible.
3) Use recommended oil per recommendation of vacuum pump
manufacturer.
