FIELD-INSTALLED ACCESSORIES

Thermostat and Subbase — Attractive wall-mounted 24-v accessory provides precise temperature control. Automatic and Manual changeover models available. A thermostat subbase is available that works with Cycle-LOC™ circuitry. If a safety device trips, compressor locks out and subbase warning light (LK OUT) alerts occupant.

Two models available: Two stage cool/two stage heat and one stage cool/one stage heat.

Time Guard® II Circuit (standard on single-phase units) — Time Guard II device prevents short cycling of compressor if thermostat is rapidly changed; automatically prevents compres- sor from restarting for 5 minutes after shutdown.

Electric Heaters — A wide range of models available from 5 to

30kW, 208-, 240- and 480-v, single- and 3-ph units. Mount eas- ily on 502A discharge opening. Heater control box accessible from the bottom of heater.

Condensate Pump — The condensate pump is used when the distance and slope to the nearest drain is far enough to prevent the natural drainage of unit. The pump is mounted remotely from the unit and includes a signal light (field-installed) which illuminates when the reservoir rises beyond a certain level. The unit automatically shuts down when this reservoir level is achieved.

Head Pressure Control Damper — This accessory is duct mounted and allows unit to mechanically cool down to 0° F.

Damper dimensions fit 024, 036 sizes.

NOTE: For use with 048 and 060 size units, ductwork from unit to damper must be reduced in size to fit damper dimensions.

Vibration Isolators — Package of four isolators used for damp- ening any unit vibration so that vibrating sounds are not transmitted to building structure. Isolators are spring, ceiling type.
