INSTALLING INSTRUCTIONS

All wiring must be installed by a certified electrician according to the local electrical codes. The ceiling heater must be grounded in accordance with all national and local building codes.

All wiring procedures and connections shall be in accordance with the national and local codes having jurisdiction.

Before installation:

Disconnect the main supply connection.

The heater must be connected to individual branch circuit.

Installation location:

1.Arrange units so their discharge air streams are subjected to a minimum of interference from columns and partitions.

2.Direct air stream away from room occupants. 3.Do not blow air steam directly at wall.

4.Direct air stream along the windward side of a room when installed in a building exposed to a prevailing wind.

5.If using a remote thermostat, locate thermostat approximately 5 feet above partition walls or posts away from cold drafts, internal heat sources, and away from heater discharge air streams.

6.Large rooms require multi-unit installations. Arrange units to provide perimeter air circulation where each unit supports the air stream from another.

MOUNTING

High temperature, risk of fire, keep electrical cords, drapery, furnishings, and other combustibles at least 3 feet (0.9 m) from the front of the heater and away from the side and rear.

To reduce the risk of fire, do not store or use gasoline or other flammable vapors and liquids in the vicinity of the heater.

Mount the heater at least 6 feet above the floor to prevent accidental contact with the fan blade which could cause injury.

To prevent possible over heating or damage due to overheating, keep at least a 5 feet clearance in front of the heater. Refer to Table 1 for side, top and back clearance requirements.

WIRING INSTRUCTIONS

BRANCH CIRCUIT (POWER)

1.Connect heater only to the voltage, amperage and frequency specified on the nameplate.

2.Field wiring must be properly sized to carry the amperage in accordance with the NEC.

3.The access door is hinged. There are either one or two screws accessible from the bottom that must be removed to gain access.

4.A knockout is provided in the back of the heater close to the power terminal board. The control terminal board knockout is 1/2 inch conduit size. The power terminal block knockout is multiple diameter. Use the diameter that fits the required conduit size.

5.A ground terminal is provided near the power terminal board. The ground wire should be connected before other connections are made. The ground wire of model as below.

	Model	Grounding wire
		AWG#
	246103	14
	246104	14
	246132	8
	246133	6
	246134	12
	246725	16
	246727	10

6.The power terminal board is equipped with box terminals sized to accept the correct size power supply wire. Wire rated at 600V and 194°F is satisfactory for the heater branch circuit. Copper wire is satisfactory for connection to the heater power terminal board box terminal.

User’s Manual Vertical or Horizontal Downflow Unit Heater

7.Each heater has a wiring diagram affixed to the inside of the access door. Consult this diagram before making any field connections.

8.Electrical Accessories, either kits or factory-installed options, are shown connected by a dashed line on the heater wiring diagram.

9.Single or three-phase connections may be used with heater models 246132 and 246133. These units are factory wired for single phase operation. If these heaters are for use with three-phase power, reconnect the wires as indicated in the wiring diagram attached to the heater.

10. Connect the red live wire to L1, black live wire to L2 and white live wire to L3 of the connector. Connect ground wire to.

11.For model 246132 and 246133, the heaters are wired for 240V from factory. When heater is to be connected to 208V supply, the transformer leads have to be inter changed. Inter change transformer red and black primary leads (see wiring diagram on heater door). The color lead is the COMMON for the 40VA control transformer provided with these heaters.

CONTROL WIRING OF OPTIONAL EQUIPMENT

Line voltage is present on some of the terminals on the control terminal board.

Always disconnect the power from the heater before making any connections to the control board to prevent hazards.

1.Use min. 600 volt, NEC Class 1 insulated wire for all control circuit wiring.

2.Use a crimp-on type fork terminal on the wire ends that attach to the control terminal board if more than one connection is to be made under the terminal screw.

3.Control wiring must be rated minimum 18 AWG.

NOTE: Thermostat and control circuit wiring must be suitable to handle the full load of the heater

OPERATION INSTRUCTIONS

1.Heater must be properly installed before operation.

2.Turn power supply “ON” at main service panel.

3.Where applicable, refer to control accessory instructions regarding proper operation of any controls or accessories used with the heater.

4.Ambient temperature is regulated by adjusting the built-in thermostat to a desired position.

5.Allow the unit to operate and warm up the room.

6.When the desired temperature is reached, turn the control knob counterclockwise until the heater turns off. This is the ideal setting.

7.The heater will start automatically when the room temperature drops below this set point, and will turn off when the set point is reached.

It is important to keep this heater clean. To assure efficient operation follow the simple instructions below.

USER CLEANING INSTRUCTIONS

1.After the heater has cooled, a vacuum cleaner with brush attachment may be used to remove dust and lint from exterior surfaces of the heater including the grille openings.

2.With a damp cloth, wipe dust and lint from grille and exterior surfaces.

3.Return power to heater and check to make sure it is operating properly.

MAINTENANCE CLEANING INSTRUCTIONS

(To be performed only by Qualified Service Personnel)

At least annually, the heater should be cleaned and serviced by a qualified service person to assure safe and efficient operation. This should include the removal of the grille and, as necessary the heater from the back box to clean residue from the unit. After completing the cleaning and servicing, the heater should be fully reassembled and checked for proper operation.

To reduce the risk of fire and electric shock or injury, disconnect all power coming to heater at main service panel and check that the element is cool before servicing or performing maintenance.
