Refrigerant Charge
1. Evacuate the unit to 300 microns and hold for 40 minutes.
2. Charge the unit with 2.72 kg of R22 refrigerant.
3. After the charge is in place the unit can be run.
Note: Trickle charging is not possible due to the low pressure switch.
Indication of correct refrigerant charge - Compressor current draw and system
pressures are within the normal range and temperatures should be consistent with system
pressure.
Indication of undercharged system – If current draw is very low combined with low
discharge line temperature then the system is totally empty. Note: Unusual current draw or
low suction pressure can be a sign of other problems such as a blockage or malfunctioning
TX valve.
Indication of overcharged system - Evaporator tends to flood, head pressure high,
compressor current draw high and compressor noisy. Note: Unusual current draw or high
head pressure can be a sign of other problems such as a blockage or malfunctioning TX
valve.
