177820-YIM-A-0506 DUCTWORK Ductwork should be designed and sized according to the methods in Manual Q of the Air Conditioning Contractors of America (ACCA). A closed return duct system shall be used. This shall not preclude use of economizers or outdoor fresh air intake. The supply and return air duct connections at the unit should be made with flexible joints to minimize noise. The supply and return air duct systems should be designed for the CFM and static requirements of the job.
PAGE 8
177820-YIM-A-0506 Do not loosen compressor mounting bolts. FILTERS One-inch or two-inch filters can be supplied with each unit. Filters must always be installed ahead of the evaporator coil and must be kept clean or replaced with same size and type. Dirty filters will reduce the capacity of the unit and will result in frosted coils or safety shutdown. Minimum filter area and required sizes are shown in Physical Data Table 7.

177820-YIM-A-0506 THERMOSTAT The room thermostat should be located on an inside wall approximately 56 inches above the floor where it will not be subject to drafts, sun exposure or heat from electrical fixtures or appliances. Follow the manufacturer's instructions enclosed with the thermostat for general installation procedure. A minimum of seven color-coded insulated wires (#18 AWG) should be used to connect the thermostat to the unit.

177820-YIM-A-0506 To check the supply air CFM after the initial balancing has been completed: 1. Remove the two 5/16” dot plugs from the blower motor and the filter access panels shown in Figure 11. 2. Insert at least 8" of 1/4 inch tubing into each of these holes for sufficient penetration into the air flow on both sides of the indoor coil. NOTE: The tubes must be inserted and held in a posi- tion perpendicular to the air flow so that velocity pressure will not affect the static pressure readings. 3.
PAGE 28
177820-YIM-A-0506 INTERMITTENT BLOWER With the room thermostat fan switch set to “AUTO” and the system switch set to either the “AUTO” or “HEAT” settings, the blower is energized whenever a cooling or heating operation is requested. The blower is energized after any specified delay associated with the operation. When energized, the indoor blower has a minimum run time of 30 seconds. Additionally, the indoor blower has a delay of 10 seconds between operations.
PAGE 29
177820-YIM-A-0506 Should a high-pressure switch open three times within two hours of operation, the UCB will lock-out the compressor and flash a code (see Table 23). LOW-PRESSURE LIMIT SWITCH The low-pressure limit switch is not monitored during the initial 30 seconds of a cooling system's operation. For the following 30 seconds, the UCB will monitor the low-pressure switch to ensure it closes.
PAGE 30
177820-YIM-A-0506 The ASCD is initiated on unit start-up and on any compressor reset or lock-out. FLASH CODES The UCB will initiate a flash code associated with errors within the system. Refer to UNIT CONTROL BOARD FLASH CODES Table 23. When the DC enters the defrost mode, it’s on-board defrost relay is powered. This energizes the reversing valve, de-energizes the condenser fan motor and energizes the unit’s optional electric heater.

Turn unit electrical power on. 2. Set the room thermostat setting to lower than the room temperature. 3. First stage compressors will energize after the built-in time delay (five minutes). 4. The second stage of the thermostat will energize second stage compressor if needed. POST START CHECK LIST 1.

Proper operation of the room thermostat (contact between R and G with the fan switch in the ON position and in the AUTO position during operation calls). b. Proper wiring between the room thermostat and the UCB. c. Loose wiring from the room thermostat to the UCB. 9.

177820-YIM-A-0506 of the UCB. If 24 volts is present, trace the wiring from Y1 “OUT” for incorrect wiring. If 24 volts is not present at the Y1 “OUT” terminal, the UCB must be replaced. 12. For units without economizers: If 24 volts is present at the Y1 OUT terminal, check for 24 volts at the Y1 “ECON” terminal.

177820-YIM-A-0506 the replacement filter must be the same as the replaced filter. MOTORS Outdoor fan motors are permanently lubricated and require no maintenance. Indoor Blower Motor and Drive - The indoor blower motor features ball bearings that do not require periodic lubrication. On an annual basis, check the motor for accumulations of dust, etc. that may block the cooling slots in the motor shell. Check for loose, damaged or misaligned drive components. Check that all mounting bolts are tight.
