CONT. WATER CHILLER STARTING CHECKLIST
ELECTRIC – POWER
A good test to make sure power is off to the unit is to turn on the water pump switch. If
power is on, the light on this pump will be on. We recommend you take caution in all
judgment about the power being on. The best test to find if the power is on is to use a
voltmeter. Please Note: A single-phase condition can cause a pilot light to be out and
still have voltage to the unit.
TESTING STANDARDS
All components on the chiller meet UL's standards. The system is tested under 250
pounds of pressure. All motors have internal overload protection except where
noted.
ANTIFREEZE
Keep the water tank filled at the proper level. Add antifreeze if you are going to operate
the unit at 36
0 F or lower. Be sure you only use industrial antifreeze. Call our office if
you need help with this.
DEIONIZED WATER
DO NOT USE DEIONIZED WATER IN THE TANK. Deionized water will cause
damage to the copper evaporator.
TANK FILL
Use the separate 1/2" line marked “tank fill” to fill the chiller. See number five on the
specification sheet for locations, page one.
