The type of refrigerant and amount per system is listed on the unit rating plate. A change in the oil color or odor may be an indication of contaminates in the refrigeration system.
Page 56: Condenser Coils
Maintenance Condenser Coils Dirt should not be al lowed to accumulate on the con dens er coil surfaces. Cleaning should be as often as nec es sary to keep coil clean. PERIODIC MAINTENANCE – THREE TO SIX MONTHS Disconnect and lock-out power from the unit anytime service is being per- formed on the fan sec tion.
Page 57: Belt Replacement
An incorrectly aligned and tensioned belt can sub stan tial ly shorten belt life or overload blow er and motor bear ings, shortening their life ex pect an cy. A belt tensioned too tightly can over load the motor electrical, causing nui sance trip ping of the motor overloads and/or motor fail ure and/or shaft fail ure.

Page 163: Alarm Trouble Shooting
ALARM TROUBLE SHOOTING Refrigerant System Alarm Codes (01, 02, 03, 04, 09, 10, 11, 12) The first 12 alarms involve controls intended to protect the compressors. Each compressor system is equipped with external circuitry monitoring hardware intended to protect the compressor in case the operating characteristics of the refrigerant system fall outside the safe operating envelope for the compressor.
Page 164: Low Pressure Cutout Alarm (09, 10, 11, 12)
Service 24 VAC power is supplied to the compressor protection module for compressor 2A from wire 443 at terminal C30 of the P12 connector. The binary input back to the Unit Controller from the compressor protection module is wire 442 at terminal C30 of the P12 connector. 24 VAC power is supplied to the compressor protection module for compressor 2B from wire 445 at terminal C40 of the P12 connector.
Page 165: Supply Air Temperature Sensor Alarm (20)
Supply Air Temperature Sensor Alarm (20) This alarm indicates the supply air temperature input is either open or shorted. The display will show a value of –40.0° F. The supply air temperature input is at SAT+ and SAT- of the P11 connector. To trouble shoot compare the resistance of the input to the actual supply air temperature using Table 8-1.
Page 166: Outdoor Humidity Sensor Alarm (29)
Service Outdoor Humidity Sensor Alarm (29) This alarm indicates the outdoor humidity sensor is out of range. When this occurs the Unit Controller will switch economizer operation to Dry Bulb. The Outdoor Humidity analog input is at OH+ wire 333 of the P6 connector and OH- wire 334 of the P6 connector.
Page 167: Supply Air Temperature Cooling Alarm (38)
Supply Air Temperature Cooling Alarm (38) The Unit Controller compares the supply air temperature to the “SUPPLY AIR TEMP ALARM FOR COOLING” and initiates the alarm based on the following criteria: • All the stages of cooling have been on for 10 or more minutes.
