WARNING
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.
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.
CAUTION
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.
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.
