SAFETY CONSIDERATIONS

Installation, start-up, and servicing of this equipment can be

hazardous due to system pressures, electrical components, and

equipment location (roofs, elevated structures, etc.).

Only trained, qualified installers and service technicians

should install, start up, and service this equipment.

When working on this equipment, observe precautions in

the literature and on tags, stickers, and labels attached to the

equipment and any other safety precautions that may apply.

GENERAL

This book contains instructions for the installation, start-up,

and service of the Motormaster V (MMV) control on

48/50P030-100 units.

The Motormaster V control is a motor speed control device

which adjusts condenser fan motor speed in response to varying

liquid refrigerant pressure. A properly applied Motormaster V

control extends the operating range of air-conditioning systems

and permits operation at lower outdoor ambient temperatures.

To operate these units at very low ambient temperatures, Mo-

tormaster V controls (Fig. 1) must be added. Field-fabricated and

installed wind baffles are also required for units in areas with pre-

vailing winds of more than 5 mph (8 kph) and where tempera-

tures drop below 32 F (0° C). The Motormaster V control permits

operation of the unit to an ambient temperature of –20 F (–29 C).

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 since the control is compatible with the

factory-installed fan motors. To verify that unit fan motors are

compatible with the control see Table 1.

See Tables 2-4 for the Motormaster V control accessory pack-

age usage and contents. Field wiring of control is required.

WARNING

Open all remote disconnects before servicing this equip-

ment. Electrical shock could result in personal injury.
