ELECTRICAL REQUIREMENTS
WARNING
ELECTRIC SHOCK HAZARD
Turn off electric power before service or instal- lation. All electrical connnections and wiring MUST be installed by a qualified electrician and conform to the National Electrical Code and all local codes which have jurisdiction. Failure to do so can result in personal injury and/or death.
NOTICE
Not following the previous WARNING could result in fire or electrically unsafe conditions which could cause moderate or serious property damage. Read, understand and follow the previous warning.
Wire Size
“Use ONLY time delayed fused disconnect or HACR type circuit breaker as indicated on the unit’s rating plate. Proper current protection to the unit is the responsibility of the owner”.
Unit MUST
All 208/230v chassis must be hard wired with properly sized breaker. See nameplate for specific chassis electrical requirements. See below for unit wiring. For wall thermostat wiring, see page 12. Use HACR type breakers to avoid nuisance trips. All field wiring must be done in accordance with NEC and local codes.
Supply voltage
Supply voltage to the unit should be a nominal 208/230 volts. It must be between 197 volts and 253 volts. Supply voltage to the unit should be checked WITH THE UNIT IN OPERATION. Voltage readings outside the specified range can be expected to cause operating problems. Their cause MUST be investigated and corrected.
