INSULATE REFRIGERANT LINES
Check that all suction lines are adequately
covered with insulation from case penetration
to compressor, including suction service
valves, and accumulator on low temp units,
as some insulation may have been dislodged
duing shipping and installation. Suction
lines are insulated to prevent condensation;
extra insulation is provided to cover the field
connected tubing sections. These exposed
sections must be covered with insulation.
Check that all suction lines are adequately
covered with insulation from case penetration
to compressor; including suction service valves
as some insulation may have been dislodged
during shipping and installation. Do not
locate the tubing above the electrical box in
order to prevent condensation from dripping
onto electrical components.
Compressor
FIELD WIRING
All wiring must be in compliance with NEC
and local codes. Field wiring must be sized for
component amperes stamped on the serial plate.
Actual ampere draw may be less than specified.
Field wiring lands on the line side of the service
disconnect.
Terminal blocks are used for field connection
of the 120V single phase and 208/230V single
phase power supply. The terminal blocks

provided as an option. When this switch is off,
some electrical terminals in the case wireway
may be energized. The wiring connection for
the condensing unit is provided with 5-ft leads
and
connected to the condensing unit electrical
