Midea Aqua Tempo Super II
Service Manual
Procedure 4.10.4
Insufficient refrigerant caused by
refrigerant leakage
1
Add refrigerant or inspect the system for
leaks
The low pressure side is blocked, caused
by crushed or bent pipe, blocked EXV, or
dirty filter
2
Inspect the system and fix the error. If the
filter is blocked by ice, the piping should
be cleaned
The air side heat exchanger heat
exchange is poor in heating mode
3
Inspect the refrigerant system and fix the
error
The water flow rate is not sufficient in
cooling mode
4
Inspect the water system and fix the
error
Notes:
1. To check for insufficient refrigerant:
An insufficiency of refrigerant causes compressor discharge temperature to be higher than normal, discharge and suction pressures to be lower than
normal and compressor current to be lower than normal, and may cause frosting to occur on the suction pipe. These issues disappear once
sufficient refrigerant has been charged into the system.
2. A low pressure side blockage causes compressor discharge temperature to be higher than normal, suction pressure to be lower than normal and
compressor current to be lower than normal, and may cause frosting to occur on the suction pipe. For normal system parameters.
3. Check air side heat exchanger, fan(s) and air outlets for dirt/blockages.
4. Check water side heat exchanger, water piping, circulator pumps and water flow switch for dirt/blockages.
