and

attach

mounting

hardware

(not included).

 

 

 

 

IMPORTANT: THE HARDWARE AND THE SUPPORT- ING STRUCTURE MUST BE CAPABLE OF SUPPORT- ING A MINIMUM 150 LB. LOAD.

NOTE: All installation should be done to meet local building code.

3.Mount cabinet on wall and securely tighten hardware.

4.Replace motor/blower assembly in cabinet. Secure two wing nuts on blower base. Reconnect motor electric cord plug assembly & heater plug.

5.Replace intake grille with louvers facing down and refasten knurled nuts.

FIELD POWER WIRING

WARNING: ALL AIR CURTAINS SHOULD BE INSTALLED BY QUALIFIED PERSONNEL.

1.Before wiring be sure that available power supply, voltage, phase and frequency corresponds to that specified on heater rating plate. In addition, make certain that service capacity is sufficient to handle load imposed by the equipment.

2.Install all wiring, protection and grounding in accor- dance with the National Electrical Code (NEC) and all local requirements.

WARNING: THIS FAN HAS AN INTERNAL SELF RESETTING THERMAL OVERLOAD PROTECTOR. ALWAYS DISCONNECT FROM POWER SUPPLY BEFORE SERVICING.

3.Run proper size copper power supply conductors from

the field power supply disconnects, (supplied by others) with insulation rated minimum 75°C (167°F). One set of conductors from 460VAC, 50/60Hz supply source shall be routed through the 3/4 inch conduit knockout, using a suitable knockout connected to the contactor contact terminals marked L1, L2, L3.

4.The heater control box must have an unbroken electrical ground to minimize personal injury if an electrical fault should occur.

FIELD CONTROL WIRING

Electric heater is equipped with a step-down transformer

for 24V control circuit. Thermostat model number RSV- 130-R-54 must be used to energize heater with the fan motor. Connect thermostat wiring from thermostat to control leads in heated air curtain control box by means

of conduit or equivalent. A 1/2 inch knockout is provided. Class 1 wiring is required.

5.Replace heater control box cover.

6.Unit is ready for operation.

7.Restore power.

NOTE: Air curtain has high/low selector switch. See Operation section for proper setting instructions.

8.Upon completion of all installation, inspect unit for excessive vibration during operation. If excessive vibration is noticeable, disconnect power supply. Inspect mounting installation and refer to Troubleshooting Chart for probable cause.
