Compressor Checkout
The compressor should be operated before being connected to the other system components.
1. Ensure that the circuit breaker on the compressor is open (handle is down).
2. Supply power to the compressor.
3. Close the circuit breaker (handle up).
4.
Press the ON/OFF rocker switch to ON position. The ON/OFF switch will light and the
compressor will start.
5. Run the compressor for ten (10) minutes and then stop.
If the compressor starts but does not build pressure, turn it off immediately. It could be running
in reverse.
6. While the compressor is running, lightly touch the water supply and return lines. The return
(water out) line should be warmer. If the return water line is cooler than the supply (water in)
line, stop the compressor and reverse the water connections.
This completes the checkout of the compressor.
