Compressor
To avoid personal injury or property damage, rotate the fan by hand prior to connecting
the unit to a power source. Check for suction at the air inlet by placing your finger over
the port as you rotate the fan. You should feel a slight suction with each rotation of the
fan. If you DO NOT feel a suction but you feel or hear a thump as you turn the fan, DO
NOT connect the unit to a power source. Review the assembly procedure for possible
error.
NOTE: For this procedure, refer to FIGURE 7.7 on page 42.
1. Reinstall compressor. Refer to Replacing Compressor Assembly on page 32.
2. Run unit and check for leaks around compressor hoses and compressor tubes. Refer
to Leak Test on page 77.
3. Take pressure readings to ensure proper system pressures. Refer to Checking Sieve
Bed Pressure on page 86.
