Procedures
CAUTION
Use Copper Conductors Only!
Unit terminals are not designed to accept other types of conductors.
Failure to use copper conductors may result in equipment damage.
[ ] Connect unit power supply cord to fused disconnect switch.
[ ] Connect power supply wiring, along with a fused disconnect switch, to
auxiliary heat tape installed on system water piping.
Pre-Start Checklist
Once the unit is installed, complete each step in the checklist that follows,
check off each step as it is completed. When all are accomplished, the unit is
ready for operation.
WARNING
Hazardous Service Procedures!
The maintenance and troubleshooting procedures recommended in
this section of the manual could result in exposure to electrical,
mechanical or other potential safety hazards. Always refer to the safety
warnings provided throughout this manual concerning these
procedures. When possible, disconnect all electrical power including
remote disconnects before servicing. Follow proper lockout/tagout
procedures to ensure the power can not be inadvertently energized.
When necessary to work with live electrical components, have a
qualified licensed electrician or other individual who has been trained
in handling live electrical components perform these tasks. Failure to
follow all of the recommended safety warnings provided, could result
in death or serious injury.
Refer to unit schematics to check the number of disconnects required to de-
energize the unit.
When electrically troubleshooting the compressor make sure electrical
power is NOT applied.
[ ] Inspect all wiring connections; electrical connections should be clean and
tight.
CAUTION
Compressor Damage!
Check tightness of all connections in the compressor power circuit
(disconnects, terminal block, contactors, compressor junction box
terminals, etc.). Failure to do so may result in over-heating at
connections and under voltage conditions at the compressor motor.
