Check all connections for leaks when piping is completed,
using a soapy solution. Some soaps used for leak detection
are corrosive to certain metals. Carefully rinse piping
thoroughly after completing leak detection.
Electrical Wiring
All wiring should be done in accordance with the
National Electrical Code, ANSI/NFPA No. 70 (latest
edition); Canadian Electrical Code Part 1, CSA C22.1
(latest edition); or local codes where they prevail. Use
wiring with a temperature limitation of 75°C minimum. Run
the electric power supply through a fused disconnect switch
to the connection box of the unit and connect as shown in
the wiring diagram located on the inside of the control access
panel.
Power supply to the unit must comply with all applicable codes
and the National Electical Code (NEC) or Canadian Electrical
Code (CEC). A fused disconnect switch should be field
provided for the unit. The switch must be separate from all
other circuits.
If any of the wire supplied with the unit must be replaced,
replacement wire must be of the type shown on the wiring
diagram. Electrical wiring must be sized to carry minimum
circuit ampacity marked on the unit. Use copper conductors
only. Each unit must be wired with a separate branch circuit
and be properly fused.
Thermostat
The room thermostat should be located on an inside wall where
it will not be subject to drafts, sun exposure, or heat from
electrical fixtures or appliances. Follow the manufacturer’s
instructions enclosed with thermostat for general installation
procedure. Color-coded insulated wires (#18 AWG) should
be used to connect thermostat to unit.
Four wires are required for cooling. The heat anticipator setting
is 0.7 amp.
Compressor
Units are shipped with compressor mountings factory-
adjusted and ready for operation. Caution: Do not loosen
compressor mounting bolts.
Any conversion of a natural gas unit to propane gas must
be done by qualified personnel using a conversion kit
available from the manufacturer, following the instructions
in the conversion kit. If done improperly, overfiring of the
burners and improper burner operation can result. This
can create carbon monoxide which could cause
asphyxiation.
WARNING
When connecting electrical power and control wiring to
the unit, waterproof type connectors must be used so that
water or moisture cannot be drawn into the unit during
normal operation.
CAUTION
