Carrier condenser unit manual

Compressor operating amps at any specific condition can only be determined from a performance curve. Ohm values for resistance are approximate and shown for reference purposes only. Factory wiring is in compliance with NEC.

Any field modifications or additions must be in compliance with all applicable codes. Use copper, copper-clad aluminum for field power supply only. Field power supply wiring must be 75 C minimum. Compressor thermally protected. Three-phase motors are protected against primary single-phasing condition. Pilot duty control must be field supplied.

Minimum contact rating must be 25 va. A separate source of supply at the correct voltage must be field supplied supply at the through a fused disconnect. Open control circuit disconnect switch for servicing only. Disconnect must remain closed for crankcase heater to operate.

A transformer of the following rating may be field supplied for 60 Hz units: va. Transformer must be fused and grounded per applicable codes. If any of the original wiring furnished must be replaced, it must be replaced with 90 C wire or its equivalent. Wiring is shown for single pumpout control. Single pumpout control should not be used on direct-expansion DX cooler applications see lower diagram for wiring when applied with DX cooler.

Installing, starting up, and servicing air-conditioning equipment can be hazardous due to system pressures, electrical components, and equipment location roofs, elevated structures, etc. Untrained personnel can perform basic maintenance functions such as cleaning coils. All other operations should be performed by trained service personnel. When working on the equipment, observe precautions in the literature and on tags, stickers, and labels attached to the equipment.

Follow all safety codes. Wear safety glasses and work gloves. Use care in handling, rigging and setting bulky equipment. Separate power sources main and control power circuits are used for these units. Is a world leader in air conditioning, heating and ventilation. Carrier has a worldwide network of hundreds of distributors and thousands of dealers who sell, install and service products in countries.

Carrier products are developed in twenty engineering centers and manufactured in factories located around the world. Part of the UnitedTechnologiesCorporation holding. Founded in , when Willis Carrier invented his first air conditioner.

Carrier's first client was a New York printer, who could not print a good quality color image because the changing temperature and humidity caused changes in the size of the paper sheet and shifts in the application of paint.

For the first two decades, Carrier's invention, which controlled indoor temperature and humidity, was used primarily to create comfortable working conditions for machines and processes, not people.
