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 structures, 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 disconnect locations to alert others not to restore power until work is completed.

Locate unit indoors. See Fig. 4 and 5 for unit dimensional details. When considering location, consult National ElectricalCode (NEC) and local code requirements. Allow sufficientspace for wiring, piping, and service. Install unit in an areawhere it will not be exposed to ambient temperatures below50 F (10 C). Allow 36 in. (914 mm) in front of the unit for control boxaccess door. Additional clearance may be required per localcodes. Prior to installation determine which direction compressor will be removed, and leave 3 to 4 ft (914 to 1219 mm) clearance for removal. On all units leave 3 ft (0.9 m) of clearance behind the unit tomake water/brine connections to the evaporator, accessing theTXV (thermostatic expansion valve), fluid thermistors, andproof of flow switch. On all units, leave 2 ft (610 mm) on one side for making refrigeration connections (30MPA) or fluid connections (30MPW) to condenser. See Fig. 4 and 5. The floor must be strong enough to support the unit operating weight (see Tables 1A and 1B and Fig. 4-6). If necessary, add a supporting structure (steel beams or reinforced concreteslabs) to the floor to transfer weight to nearest beams...
