If the Compressor Does Run
(Presuming that the Cold water is not being cooled sufficiently)
1. Check the small pipe on the 'high' side of the compressor. This should be quite warm after several minutes of
normal operation.
2. Following it to the condenser, check the condenser temperature. Normally the beginning will be warmer,
cooling off towards the end.
• No or very low temperature could indicate a low refrigerant charge. A low current draw would indicate this.
(Contact Azure Technical Support).
• An overly high temperature could indicate a blockage; A high current draw would confirm this. (Contact
Azure Technical Support).
3. Continue to follow the pipe work from the end of the condenser to the dryer.
• A frozen / iced dryer will indicate a blockage (Contact Azure Technical Support) Again; a high current draw
would confirm this.
4. The dryer exits into the capillary tube. Check this for restrictions and NB: This has a very small bore.
5. The Capillary enters the evaporator. This can be checked visually for any obvious signs of deterioration.
6. The evaporator connects back to the 'low' side of the Compressor via the suction pipes.
Check this for excessive icing.
Excessive icing could indicate a refrigerant overcharge (Contact Azure Technical Support).
