essential checks which must be completed. Failure to carry
out these checks could result in damage to the chiller

Refrigeration
1. Refrigerant piping and components should be inspected
for damage.
2. Place refrigerant gauges on the discharge and suction
access ports of each refrigerant circuit to ensure a
refrigerant charge is present. Leave the gauges on for
compressor rotation check.

WARNING
This unit contains HFC-(R410A), an azeotropic mixture of R-32 (Difluoromethane) and R-125 (Pentafluoroethane).
DO NOT VENT HFC-(R410A) to the atmosphere. The U.S. Clean Air Act requires the recovery of any residual
refrigerant. Do not use R-22 service equipment or components on R410A systems.
WARNING!
To avoid possible injury or death due to electrical shock, open the
power supply disconnect switch and secure it in an open position
during installation.
CAUTION!
Use only copper conductors for field installed electrical wiring. Unit
terminals are not designed to accept other types of conductors.
