WIRING

Electric Shock Hazard. Heater case must be effec- tively grounded in accordance with the National Electrical Code to avoid hazard of electric shock.

NOTE: All electrical wiring must be installed in accordance with the National Electrical Code and local codes by a qualified person.

1.This heater is for use on 120, 208 or 240 volts. (See heater nameplate.) The cord has a plug similar to one shown in

Figure 10. (Consult Table A for actual plug configuration.) No adapter is available for these blade type configurations, and none should be used.

An appropriate 20A @ 125V, 15A @ 250V or 20A @ 250V grounding outlet must be used. When properly installed, it provides a ground connection through the cord to the heater to protect the operator from electric shock.

2.Connect heater according to the voltage and frequency speci- fied on the nameplate and using the appropriate wiring dia- gram (below).

MAINTENANCE

1.Hazard of Electric Shock. Disconnect all power before attempting to service this heater.

Do not attempt to service heater while unit is operating as there is hazard of electric shock, injury from operating fan and burns from hot heating elements.

2.Following long periods of idleness, heater should be vaccu- umed before start-up, to remove accumulated combustible particles which otherwise may smoke or incinerate on initial heat up.

3.When heater is not in use, store in safe location to prevent heater and/or power cord damage.

4.HF heaters use permanently lubricated motors, do not attempt to lubricate.
