Chromalox DS-50600 Instructions For Installing Wall Mounted Star-Gf, Maintenance

INSTRUCTIONS FOR INSTALLING WALL MOUNTED STAR-GF

1.Check voltage on heater nameplate and STAR-GF to make cer- tain voltages are the same. If voltages do not match, consult factory.

2.The STAR-GF will provide ground fault protection for STAR Radiant heaters. The number of heaters serviced by one (1) STAR-GF is dependent on the number and length of the heat- ing elements. See Table 2.

3.See Instruction Sheet PG434 (provided with heater) for IMPORTANT INSTRUCTIONS and WIRING.

4.Using the STAR-GF as a template mark mounting holes on wall. Use an anchoring method adequate to support the weight.

5.Wire between STAR-GF and heater, wire to terminal block. Service entrance wiring to be made to contactor connectors. For wire gage see Table 1 of PG434.

6.The ground fault sensor has been factory set at .03 Amps, DO

NOT CHANGE THE SETTING.

MAINTENANCE

The Chromalox STAR-GF ground fault sensor provides a reli- able and cost effective method for sensing ground faults. The pur- pose is to monitor for ground faults, sense potential heater failure symptoms and to protect equipment.

The current-carrying wires are routed through the current transformer on the control. When ground current reaches the level set by the trip point adjustment, (.03 Amps), the relay trips, illu- minates the tripped LED and provides an output signal which de- energizes the magnetic contactor.

ELECTRIC SHOCK HAZARD. Disconnect all power to heater before installing or servicing kit(s).

Failure to do so could result in personal injury or property damage. Kit(s) must be installed by a qualified person in accordance with the National Electrical Code, NFPA 70.

If heating element(s) fail to operate:

1.Open door of enclosure. DANGER: Hazard of Electric Shock. If "Tripped" indicator is on, this indicates one or more heating elements are about to fail. Disconnect power and fol- low the GF Troubleshooting Diagram below.

2.If the "Tripped" indicator is not on, check for blown fuses or failed components within the heater's electrical system.
