1 Motor Master ontrol Kit ancels: IIK 561A-18-1 IIK Installation Instructions Part No. 32LT and 005 This symbol indicates a change since last issue. INTRODUTION These instructions cover the installation of Motor Master control kits Part No. 32LT and 32LT on all residential single speed air conditioners and heat pumps. The device is designed to control the outdoor fan motor speed under low outdoor temperature conditions. A fan motor with ball bearings is required. The control is available in 2 models; 32LT is rated for 208/230v, and 32LT is rated for 460v. Other accessories may be required, read Required Unit hanges section of this document. assembly to be mounted to a return bend on the unit s condenser coil. A wire from the sensor is connected to the circuit board in the control box. Parts necessary for mounting control and sensor assembly are included in the kit. Either assembly can be replaced independently of the other. If any damage to the printed-circuit board or components is observed when unpacking control assembly, return for replacement. SAFETY ONSIDERATIONS Installing and servicing air conditioning equipment can be hazardous due to system pressures and electrical components. Only trained, qualified personnel should install, start-up, and service this equipment. Untrained personnel can perform basic maintenance functions such as cleaning coils, or cleaning and replacing filters. All other operations should be performed by trained service personnel. When working on the equipment, observe precautions in the literature, tags, stickers, and labels attached to the equipment and to any other safety precautions that apply. Understand the signal word DANGER, WARNING, or AU- TION. These words are used with the safety-alert symbol. DAN- GER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies hazards which could result in personal injury or death. AUTION is used to identify unsafe practices which would result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation. Follow all safety codes. Wear safety glasses and work gloves. Before beginning any installation or modification, be sure the main electrical disconnect switch is in the OFF position. Electrical shock can cause personal injury or death. DESRIPTION AND USAGE The Motor Master control is a fan speed control device activated by a temperature sensor. It is specifically designed to control condenser fan motor speed in response to the saturated condensing temperature during operation in cooling mode only. For outdoor temperatures down to -20 F, it maintains condensing temperature at 100 F ± 10 F. (See Fig. 1.) The mounting control consists of a solid-state circuit on a printed-circuit board in an aluminum extrusion, and a sensor Fig. 1 Motor Master ontrol The Motor Master control maintains the proper condensing temperature at any ambient temperature down to -20 F. No field adjustments or calibrations are required. The following must be observed: If special fan motors or transformers are required, install where necessary. Measure unit power supply voltage. It must meet minimum voltage specified on unit rating plate and match voltage rating of Motor Master control. Make sure all units are modified for winter start control when needed. heck that the control location is as specified. heck that the sensor location is as specified. Make sure that sensor wiring routing is as specified. Make sure wind baffles are installed only if required. For heat pump units, make sure isolation relay is available. INSTALLATION Exercise extreme caution when drilling holes. Do not puncture coil and/or tubing. Step 1 Mounting ontrol Assembly 1. Make sure all power to unit is turned off. A93157 Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations. Book 1 4 P 101 atalog No Printed in U.S.A.

Fasten control assembly to unit with 4 No. 10 sheet metal screws provided. NOTE: When properly positioned (mounted vertically with leads protruding from bottom of control), control is weathertight. Step 2 Mounting Sensor Mount sensor on a specified condenser coil return bend as shown in Fig. 4. For single/double row coils, sensor location is always 2 return bends down from top on entering air side of coil.

Winter start control Part No. KAAWS0101AAA must be wired in parallel with lowpressure switch. (See Fig. 6.) This will allow a delay of approximately 3 minutes before low-pressure switch becomes a part of control circuit. NOTE: It is recommended that evaporator freeze thermostat Part No. KAAFT0101AAA be attached to the vapor tube near the evaporator coil to prevent coil freezing. Wire thermostat in series with 24-v contactor coil. (See Fig. 7.) 6. Wind baffles Use only in installations where high winds are prevalent to prevent cross currents from causing abnormal control operation. For construction, refer to appropriate wind baffle figures and tables at rear of instruction. NOTE: For horizontal discharge units, use wind baffle Part No. KSAWB0101AAA for sizes 018 through 036 single phase and KSAWB0201AAA for 3-phase sizes 036, 048, and LPS LPS TDR T LPS Fig. 6 Winter Start ontrol A93165 NOTE: When wind baffles are used, raising the unit off the pad with 4-in. support feet is recommended. This will provide better airflow for moderate and high ambient temperatures. 7. Wiring Motor Master control must be wired in series with fan motor. (See Fig. 8.)

(See Fig. 7.) 5. Wind baffles Use only in installations where high winds are prevalent to prevent cross currents from causing abnormal control operation. For construction, refer to appropriate wind baffle figures and tables at rear of instruction. NOTE: For horizontal discharge units, use wind baffle Part No. KSAWB0101AAA for sizes 018 through 036 single phase and KSAWB0201AAA for 3-phase sizes 036, 048, and Isolation relay Mount isolation relay in unit control box and wire into power and control circuits. This relay will switch Motor Master ontrol out of outdoor fan motor circuit when heat pump switches to heating cycle. Relay Part No. KHAIR0101AAA is recommended for use with 208/230-v and 460-v systems. a. Normally closed relay contacts must be in parallel with the Motor Master control as shown in Fig. 9. b. Normally open relay contacts must be in series with the Motor Master control as shown in Fig. 9. c. Isolation relay coil must be connected across circuits O and on the defrost board. 7. Wiring Motor Master control must be wired in series with fan motor. (See Fig. 9.) Power wiring must comply with all local codes and National Electrical ode (NE) requirements. START-UP To start up units equipped with the accessory Motor Master control: 1. Turn unit power on. 2. Set thermostat below room temperature. 3. Wait at least 5 minutes if unit is equipped with a delay circuit. Fan motor starts 15 sec before compressor when standard delay circuits are used and may: a. Not operate when ambient is below 50 F. b. Run at slow speed when ambient is between 70 F and 80 F. c. Run at or near full speed when ambient is above 80 F. 4. When compressor starts, fan speed will modulate smoothly to proper controlled speed based on saturated condensing temperature. After system has run and settled out, saturation temperature is approximately 100 F ± 10 F, if the outdoor ambient is below 60 F. SERVIE No field repairs are to be made on this kit. If either the sensor or the control fails, it should be replaced. If the fan motor does not turn, check the control as follows: 1. heck power to condensing unit. 2. heck for voltage across fan motor relay contacts.

If fan motor runs, make sure that motor was wired in series with Motor Master control. 5. If motor runs when connected to single-phase voltage supply, but does not run when connected in series with Motor Master control, check sensor as follows: a. heck temperature of return bend near sensor with an electronic thermometer. b. Disconnect both sensor leads. c. heck sensor resistance with an ohmmeter and compare resistance/temperature readings to those in Fig. 10. d. If sensor is within tolerance shown in Fig. 10, replace Motor Master control. If sensor is NOT within tolerance shown in Fig. 10, replace sensor. 6
