3 — Legs and Gussets © 2 Compressor Mounting 38AD024,028,034 UNITS - As shipped, compressor is held down by special self-locking bolts and plain lockwashers. After unit is installed, remove the self-locking bolts one at a time and reassemble with flanged washers and neoprene snubbers as shown in Fig. 4. Special flanged washers and neoprene snubbers are shipped in a cloth bag tied to one of the compressor feet. Tighten all four bolts. Then, loosen each until the flanged washer can be moved sidewise. Motormaster® (32 Series) Head Pressure Controller — Refer to MOTORMASTER Instructions shipped with this accessory, plus the following information. Control box and sensor location is shown in Fig. 6. Electrical connections are shown in Fig. 7. Refer to unit label diagram as required. On 200-, 208- and 230-volt units, outdoor fan motor no. 1 (OFMj), located nearest the compressor, may be used with MOTORMASTER without modification. For 460- and 575-volt units, refer to Table 4 for field-supplied components needed with MOTORMASTER. Fig. 5 — Refrigerant Connections Fig. 6 - MOTORMASTER Control Box and Sensor Location 38AD044, 38AB054,064 AND 084 UNITS (compressors are mounted on a common support channel) — Remove the four shipping bolts from mounting channels prior to start-up. Fig. 4 — Compressor Mounting (38AD024,028 and 034) Fan Thermostat — Route the thermostat control bulb and capillary (located in compressor section) thru grommeted hole in compressor section base pan. Do not kink capillary. Position bulb in inlet air stream and secure to inlet air flange adjacent to compressor section. Use clamp and screw provided in parts package. If accessory head pressure control damper section is used, secure bulb to air inlet side of damper. Use hole in damper frame. Integrate Unit (38AB054,064 and 084 only) — Connect refrigerant piping between the two sections, using materials furnished with unit. Arrange discharge and liquid lines as shown in Fig. 5 and braze as indicated. Electrically connect unit control box and junction box on coil (only) section by using flexible fan conduit furnished in the unit. Use the mating, quick-connect, polarized plugs furnished in the two sections to make the wire connections. 3 FROM FAN CONTACTOR 200, 208, 230 OR 460 VOLTS 200-, 208-, AND 230-V0LT UNITS MOTOR SUITABLE FOR I USE WITH I32LT /MOTORMASTER SPEED CONTROLLER '//////'/////T7//7 / 32LT MOTORMASTER <1 '/////////////////A 460-V OR 575-V UNITS SENSOR 200-, 230-V RATED CONTROLLER MOTOR FOR 208-, 230-V OPERATION SENSOR *Use 230-volt controller with 200-,208- or 230-volt motors Fig. 7 — Motormaster® Electrical Connections Table 4 — Components Required for MOTORMASTER Use UNIT MODEL RUN CAPACITOR TRANS- FORMER MOTOR 38AD024 600 100 HC96LH020 HT01AH951 HT01AH959 HC46VL220 or HC46VL221 38AD028 38AD034 38AD044 38AB054 38AB064 38AB084 600 HC96LH030 HT01AH952 HC52TE230 100 HT01AH954 REFRIGERANT PIPING Refrigerant Line Sizes will depend on length of piping required between condensing unit and evaporator. Consideration must be given to liquid lift and to compressor oil return. Refer to Part 3 of Carrier System Design Manual for line sizing information and Fig. 8 for recommended piping details. Single Pumpout Control — All units are factory wired to operate on single pumpout control and require a field-supplied liquid line solenoid valve, sized for minimum pressure drop, to be installed immediately ahead of each expansion valve. If unit is to be used with a chiller, wiring modifications may be necessary. Refer to 38AB Application Data, Chilled Water Applications. Refrigerant Drier and Moisture Indicator — A filter-drier(s) and a liquid-moisture indicator are shipped with unit for field installation. Refer to Fig. 9 for typical recommended piping arrangements and to Table 5 for physical data on driers. Receiver — No receiver is provided with unit. It is recommended that one not be used. Piping Procedure — Do not remove plastic dust plugs from suction and liquid line stubs in compressor compartment until piping connections are ready to be made. Pass nitrogen or other inert gas thru piping while brazing, to prevent formation of copper oxide.
