hot water volume produced is less. We can adopt formic acid, citric acid, acetic acid or other organic acid
to clean.
●The dirt retention on the surface of evaporator fin should be blew by more than 0.6Mpa compressor air,
brushed by fine copper wire, or flushed by high pressurized water, usually one time per month; if too much
dirt, we can use paintbrush dipping gasoline to clean.
●After long downtime, if we restart the equipment, we should make following preparations: examine and
clean the equipment carefully, clean the water pipeline system, examine the water pump, and fasten all
the wire connections.
●Replacement parts must use our company original accessories, can not be replaced by other similar
accessories.
10.2 Refrigerant filling
Examine the refrigerant filling condition through reading the data of liquid level from display screen, also
the air suction and exhaust pressure. If there is leakage or changing components of the refrigeration
circulation system, we have to make air tightness examination first.
10.3 Leak detection and air tightness experiment:
During leak detection and air tightness experiment, never let the refrigeration system filling oxygen,
ethane or other flammable harmful gas, we can only adopt compressed air, fluoride or refrigerant for such
experiment.
10.4 To remove the compressor, please follow the following steps
●Turn off the power supply
●Exhaust the refrigerant from the low pressure end, attention to reduce the exhaust speed, and avoid
frozen oil leakage.
●Remove the compressor air suction and exhausting pipe.
●Remove the compressor power cables.
●Remove the compressor fixing screws.
●Remove the compressor.
10.5 Conduct regular maintenance according to the user manual instruction, to make sure the unit
running in good condition.
●Fire prevention: if there is a fire, please turn off the power switch immediately, put the fire out with fire
extinguisher.
●To prevent flammable gas: the unit working environment should stay away from gasoline, ethyl alcohol
and other flammable materials, to avoid explosion accident.
●Malfunction: if malfunction occurs, should find out the reason, eliminate it and then reboot the unit.
Never boot the unit forcibly if the malfunction has not been eliminated. If refrigerant leakage or frozen
liquid leakage, please turn off all the power switch, if the unit can not stop buy controlling switch, please
turn off the general power switch.
●Never short connect the wire for protection required device, or else, in case unit malfunction, it can not
be protected normally and will damage the unit.
