￿WARNING

Hazardous Voltage

Disconnect all electric power including remote disconnects before servicing. Failure to disconnect power before servicing can cause severe personal injury or death.

￿WARNING

Hazardous Voltage

Do not use any tools (i.e. screwdriver, pliers, etc.) across the terminals to check for power. Use a voltmeter. Failure to disconnect power before servicing can cause severe personal injury or death.

Standard units are shipped for use on 115 volt, 60 hertz single phase electric power. The motor nameplate and electrical rating on the transformer should be checked before energizing the unit heater electrical system. All external wiring must conform to ANSI/NFPA No. 70- 2002, National Electrical Code (or the latest edition) and applicable current local codes; in Canada, to the Canadian Electrical Code, Part 1 CSA Standard C22.1.

It is recommended that the electrical power supply to each unit heater be provided by a separate, fused and permanently live electrical circuit. A disconnect switch of suitable electrical rating for each unit heater should be located as close to the controls as possible. Each unit heater must be electrically grounded in accordance with National Electric Code, ANSI/NFPA No. 70-2002 (or the latest edition of) or CSA Standard C22.1. Sample wiring connections are depicted in Figure 38 through Figure 40.

Operation

Most basic unit heater systems are controlled by a room thermostat. Locate thermostat on inner wall or column so that optimum control could be obtained for that area. Set thermostat for desired temperature.

On steam systems a low limit may be used to prevent fan from blowing

cold air unless the heater has steam passing through the coil.

Small hot water systems could have the circulating pump controlled directly by the room thermostat. On large systems, zone valves could be used to control the individual unit heater where constant water circulation is used on the main system.

A louvered cone air diffuser is readily available as an optional accessory for vertical unit heaters. See catalog for details.

Thermostat Wiring and Location

Note: The thermostat must be mounted on a vertical vibration-free surface free from air currents and in accordance with the furnished instructions.

Mount the thermostat approximately 5 feet (1.5 m) above the floor in an area where it will be exposed to a free circulation of average temperature air. Always refer to the thermostat instructions as well as our unit wiring diagram and wire accordingly. Avoid mounting the thermostat in the following locations:

1.Cold areas - Outside walls or areas where drafts may affect the operation of the control.

2.Hot areas - Areas where the sun’s rays, radiation, or warm air currents may affect control operation.

3.Dead areas - Areas where air cannot circulate freely, such as behind doors or in corners.

Note: For all wiring connections, refer to the wiring diagram on the motor nameplate.

Should any original wire supplied with the heater have to be replaced, it must be replaced with wiring material having a temperature rating of at least 105° C.

Motors

The standard 115/1/60 motors provided on Vertical Unit Heaters are totally enclosed, Class “B” insulated and have built-in thermal overload protection.

Vertical Units 42 through 80 use sleeve type bearings. Vertical Units 122 through 280 use permanent split capacitor motors with ball bearings.

All sleeve bearing motors have oil holes to allow lubrication. Ball bearing motors are permanently lubricated although some three phase or special motors have removable plugs which will allow field installation of grease fittings.

The standard 42 through 102 motors can be converted to variable speed operation with the addition of the solid state speed control.

See Figure 32 through Figure 37 for typical wiring diagrams.
