ONNECTIONS
If you disconnect the Chiller
from the main power supply
and reconnect it, the Chiller
needs 15 minutes for the
crankcase heater to warm
up. You can not use the
Chiller during this time.
Open electrical enclosure.
Check the short-to-ground with an ohm meter.
Connect the ohm meter to each of the three terminal
screws and to the grounding lug. Test all three for resis-
tance. The maximum resistance to ground should be 1
megohm. If it resistance is more than 1 megohm there is a
leak in the system.
WARNING: Electrical hazard
Before performing any work on this item, dis-
connect and lock out electrical power sources to
prevent injury from unexpected energization or
startup.

WARNING: Initial startup
Do not press any buttons after initially applying
power to the Chiller. Let the Chiller set, undis-
turbed, for a minimum of 8 hours before starting
the Chiller. This is necessary to allow the
crankcase heater to warm properly, and to pre-
vent the refrigerant from pooling in the com-
pressor.
