Step 20 — Install Optional Motormaster® V Control — The Motormaster V control is a motor speed control device which adjusts condenser fan motor speed in re- sponse to varying liquid refrigerant pressure. A properly applied Motormaster V control extends the operating range of air-condi- tioning systems and permits operation at lower outdoor ambient temperatures.

The optional Motormaster V controls are factory-installed. Field-fabricated and installed wind baffles are also required for units in areas with prevailing winds of more than 5 mph and where temperatures drop below 32 F. The Motormaster V con- trol permits operation of the unit to an ambient temperature of –20 F. The control regulates the speed of one or two 3-phase fan motors depending on unit size. Replacement of the fan motor on most units is not necessary.

INSTALL FIELD-FABRICATED WIND BAFFLES

On size 040-060 units, in areas with prevailing winds of more than 5 mph and where temperatures drop below 32 F, wind baffles must be field fabricated to ensure proper cooling cycle operation at low-ambient temperatures with Motormaster V controls. Wind baffles are not needed on size 030, 035, and 070-100 units. See Fig. 70 for baffle details. Use 20-gage galva- nized sheet metal, or similar corrosion-resistant material for the baffles. Use field-supplied screws to attach baffles to unit. Screws should be 1/4-in. diameter or larger. Screws should not be more than 1/2-inch in length. Drill required screw holes for mounting baffles.

CAUTION

To avoid damage to refrigerant coils, electrical compo- nents, and wiring use extreme care when drilling screw holes and screwing in fasteners.

WARNING

To avoid the possibility of electrical shock, open all discon- nects before installing or servicing this accessory.
