Page 48: Overall Checking
Overall Checking Ensure that: 1) The unit has been mounted solidly and rigid in position. 2) The piping and connections are leak-proof. 3) Proper wiring has been installed. Drainage Check Pour some water into the left side of the drain pan (the drainage is at the right side of the unit). Test run: 1) Conduct a test run on the unit after having performed the water drainage test and the gas leakage test. -
Page 49: Cleaning System Flushing
Additionally, the heat exchanger may become clogged which reduces compressor service life or causes premature failure. A System Saver® from McQuay International should be employed to continuously remove solids as the system operates. Contact your local representative for further information on this device. -
Page 50: Startup
Startup Open all valves to full open position and turn on power to the conditioner. 1. Set mode to “Cool”. Set the cooling temperature to the coolest position. Again, many conditioners have time delays which protect the compressor(s) against short cycling. After a few minutes of operation, check the discharge grilles for cool air delivery. -
