If the air flow in the condenser coil is blocked, it will affect the heat exchange efficiency and cause
high exhaust pressure and cooling loss to the compressor. Clean the coil with the compressed air,
coil cleaner and water to clear away the dust and impurities that block the air flow. Do not let the
snow pile up above or around the condenser in winter. Meanwhile, check if the coil fin is
backwound or damaged, repair it if necessary. Check all the connecting pipes to see if they vibrate,
and fix them if necessary. Check all the cooling pipes carefully to see if there is any oil leakage.
Replacement steps
If the compressor motor is burnt down (it seldom happens if the system is correctly installed):
Usually, the motor is burnt down after the mechanical or lubrication faults happen.
Early detection can avoid lots of problems, such as compressor damage. Periodic maintenance and
inspection conducted by the maintenance person can effectively save the maintenance cost. To do
necessary preventive maintenance, which is easy to operate with low cost, is much better than
ignoring the problem until the compressor is damaged and replaced with high cost. When repairing
the compressor, check all the electronic components to see if they operate normally.
Avoid directly touching the gas and machine oil with your skin. Direct touch may cause injures.
Wear long rubber gloves when disposing the polluted component.
1) Check all the fuses and circuit breakers.
2) Check the operating condition of the pressure switch.
3) When the compressor fails, confirm whether it is circuit fault or mechanical fault, and take
corresponding measures.
If it is the compressor that fails, replace it. If the motor is burnt down, replace it and clean up the unit.
Please note that if one system is burnt down successively, it is probably caused by incomplete clean.
When a serious burnout happens, the machine oil will be black and acid. In this case, clean the
whole cooling system (including the indoor evaporator, outdoor condenser, refrigerant connecting
pipes and expansion valve) before replacing the compressor, and then replace the drying filter.
You can get another compressor from the product supplier of Envicool and the supplier will transfer
the compressor packaged in a reusable wooden box to the site (in accordance with the after-sales
service). If the compressor to be replaced is under warranty, it shall be sent back to Envicool to get
warranty service. The compressor should be placed in its original packaging box used when it is
purchased. Fill in the possible cause or conditions that cause the damage on the maintenance sheet
enclosed with the compressor.
The correct steps to remove and replace the compressor are as follows:
a) Cut off the power supply;
b) Install the low pressure and high pressure gauges to the corresponding connectors.
