GUIDE SPECIFICATIONS — SIZES 155-300 (cont)

18. Glycol Coil:

Coil shall be 2-row copper tube (1/2-in. OD) with aluminum plate fins (590 fins/m; 15 fins/in.) and (41.28 mm; 1.625 in. OD) copper headers. Input and output connections shall be (41.28 mm; 1.625 in. ODM) copper stubs for sweat connections. Coil shall be furnished with suitable support rails, end plates, and hardware for ready field installation in heater compartment.

19. Alternate Drive:

Shall provide higher static drive capability to en- hance evaporator-fan performance rpm range.

20. Hail Guard, Condenser Coil Grille:

Shall protect the condenser coil from hail, flying debris, and damage by large objects without increas- ing unit clearances.

21. Outdoor Air Enthalpy Sensor:

The outdoor air enthalpy sensor shall be used with the EconoMi$er device to provide single enthalpy control. When used in conjunction with a return air enthalpy sensor, the EconoMi$er device will provide different enthalpy control. The sensor allows the

EconoMi$er controller to determine if outside air is suitable for free cooling.

22. Return Air Enthalpy Sensor:

The return air enthalpy sensor shall be used with the EconoMi$er device. When used in conjunction with an outdoor air enthalpy sensor, the EconoMi$er device will provide differential enthalpy control.

23. Return Air Temperature Sensor:

The return air temperature sensor shall be used with the EconoMi$er device. When used in conjunction with the standard outdoor air temperature sensor, the EconoMi$er device will provide differential tem- perature control.

24. Light Commercial Thermidistat:

Field-installed wall-mounted thermidistat is used to control temperature and activation of the dehumidifi- cation package. The thermidistat can be set for humidity settings from 50% to 90% relative humidity.
