Startup Checklist
Check the shipping papers against the serial tag to make sure that system size, type, and
voltage is correct for the process under control.
Check the transformer primary voltage connections to be sure they are configured for the
electrical power you are using. The voltage at the main power connection must be within
plus or minus ten percent (±10%) of the voltage listed on the serial tag. Electrical
connections must conform to all applicable codes. Make sure that a qualified electrician
checks all electrical connections.
The safety thermostat is preset at the factory to 250°F (121°C). It trips at 265°F (129°C).
The relief valve should be piped to an open, unrestricted drain.
TO PROCESS, FROM PROCESS, WATER IN, WATER OUT, and MOLD PURGE connections
should be complete.
Only use components rated at a minimum of
150 psig and 250°F (1034 kPa/10.3 bar and 121°C).
All outer panels must be in place.
All external process valving should be set for proper operation of the unit.
Cooling and/or makeup water between 16 psig and 55 psig (110 kPa/1.1 bar and 379
kPa/3.8 bar) must be available for the unit to operate properly.
Connect the main power to the unit disconnect switch, and press the START switch to check
for proper pump rotation direction as described in Section 4-8 (Checking Motor Rotation) on
Page 31. Pump rotation should be clockwise, viewed from the motor end.
Check your work and proceed to the Startup Procedure section on the following page.
