Carrier Model Number: 38MGR

PART 1 – GENERAL

1.01 System Description

A. Outdoor air−cooled split system compressor sections suitable

for on−the−ground, rooftop, wall hung or balcony mounting.

Units consist of a variable speed rotary compressor, an

air−cooled coil, propeller−type draw−through outdoor fan,

reversing valve, accumulator, electronic expansion valves,

multiple service valves, and controls that allows multiple

indoor units to be connected to the outdoor unit. Units

discharge horizontally as shown on the contract drawings.

Units function as the outdoor component of an air−to−air heat

pump system.

B. Units are designed to be used in a refrigeration circuit matched

to two, three, four, or five multi style heat pump fan coil units.

1.02 Agency Listings

A. Unit construction complies with ANSI/ASHRAE 15, latest

revision, and with NEC.

B. Units are evaluated in accordance with UL standard 1995.

C. Units are listed in CEC directory.

D. Unit cabinet is capable of withstanding 500-hour salt spray test

per Federal Test Standard no. 141 (method 6061).

E. Air-cooled condenser coils are leak tested at 550 psig.

1.03 Delivery, Storage, And Handling

Units are shipped in one piece and are stored and handled per the

manufacturer’s recommendations.

PART 2 – PRODUCTS

2.01 Equipment

A. General:

Factory assembled, single piece, air-cooled outdoor unit. Contained

within the enclosure are the factory wiring, piping, controls, and

compressor.

B. Unit Cabinet:

1. The unit cabinet is constructed of galvanized steel,

bonderized and coated with baked-enamel finish on inside

and outside.

2. The unit access panel is removable with the minimal screws

and provides full access to the compressor, fan, and control

components.

3. The outdoor compartment is isolated and has an acoustic

lining to assure quiet operation.

C. Fans:

1. The outdoor fans are direct-drive propeller type, and

discharge air horizontally. The fan draws air through the

outdoor coil.

2. Outdoor fan motors are multi−speed, totally-enclosed,

single phase motors with permanently lubricated ball

bearings. The motor is protected by internal thermal

overload protection.

3. The shaft has an inherent corrosion resistance.

4. Outdoor fan openings are equipped with metal/mesh PVC

coated protection grille over fan.

D. Compressor

1. The compressor is fully hermetic variable speed rotary type.

2. The compressor is inverter driven.

3. The compressor is equipped with an oil system, operating

oil charge, and motor.

4. The motor is suitable for operation in a refrigerant and oil

atmosphere.

5. The compressor assembly is installed on rubber vibration

isolators.

6. The inverter and compressor are protected against over

temperature and over current.

E. Outdoor Coil:

The coil is constructed of aluminum blue hydrophilic pre−coated

fins mechanically bonded to seamless copper tubes, which are

cleaned, dehydrated and sealed.

F. Refrigerant Components:

Refrigerant circuit components include multiple brass external

liquid line service valves with service gauge connection port,

multiple suction line service valves with a service gage connection

port, accumulator, reversing valve, electronic expansion valves.

G. Safeties:

Operating safeties are factory selected, assembled, and tested. The

minimum functions include the following:

1. Compressor discharge over temperature protection.

2. System low voltage protection.

3. Compressor overload protection.

4. Compressor over current protection.

5. IPM module protection.

H. Electrical Requirements:

1. Units shall operate on single-phase, 60 Hz power at

208/230v.

2. The unit electrical power is a single point connection.

3. All power and control wiring must be installed per NEC

and all local electrical codes.

4. Units have multiple terminal blocks to connect to multiple

indoor units.

Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.
