Carrier 30MPA - Manual

A technical manual for Carrier Aquasnap® liquid chillers with scroll compressors and ComfortLink™ controls covers their installation, operation, and integration into refrigeration systems. The document includes detailed specifications–such as dimensional layouts, weight distributions, and performance metrics (e.g., refrigerant capacity, compressor data)–for air-cooled (30MPA) and liquid-cooled (30MPW) models across multiple sizes. It also addresses critical topics like safety precautions during installation, piping configurations for fluid loops, water pressure drop characteristics in evaporators and condensers, and electrical wiring requirements, including phase voltage balance compliance with standards like ASHRAE and NEC.

GENERAL

These installation instructions cover the 30MPA, MPW units

with

Comfort

Link controls. The 30MPA units are condenserless

units and the 30MPW units are all fluid cooled.

SAFETY CONSIDERATIONS

Installing, starting up, and servicing this equipment (Fig. 1

and 2) can be hazardous due to system pressures, electrical

components, and equipment location (roofs, elevated struc-

tures, etc.). Model number structure is shown in Fig. 3.

Only trained, qualified installers and service technicians

should install, start up, and service this equipment.

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.

WARNING

Electrical shock can cause personal injury and death. Shut

off all power to this equipment during installation. There

may be more than one disconnect switch. Tag all discon-

nect locations to alert others not to restore power until work

is completed.
