INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS SAFETY CONSIDERATIONS INSTALLATION Installing, starting up, and servicing equipment can be hazardous due to system pressures, electrical components and equipment location (roofs, elevated structures, etc.). Only trained, qualified installers and service mechanics should install, start up, and service this equipment. STEP 1 COMPLETE PRE-INSTALLATION CHECKS Examine for damage incurred during shipment.
INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS Drain traps on low temperature unit coolers must be outside of refrigerated enclosures. In the instance where traps are subject to freezing temperatures, wrap the traps with heat tape and insulation. Always trap drain lines individually to prevent vapor migration. STEP 5 - REFRIGERANT CONNECTIONS All refrigerant system components must be installed in accordance with applicable local and national codes using proper engineering practices.
INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS NOTE Minimum compressor suction superheat of 20ºF may override these recommendations on some systems with short line runs. DEFROST SYSTEM SERVICE AIR DEFROST UNIT COOLERS: Fan motors run continuously and a defrost time clock or low-pressure setting stops the compressor when defrost is required. INSPECTION After one day of operation, check for any vibration in the unit cooler.
INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS UNIT SPECIFICATIONS FOR ALL UNITS: - For R-134a or R-22 refrigerant charge, multiply R-404 by 1.09. - Operating charge is based on 30% liquid and 70% vapor at 25ºF suction. LS SERIES: - Use LSR model for hot gas reverse cycle defrosts. - Use LST model for hot gas three pipe defrost with gas drain pan. - Air throw for LS Series: 25 to 35 feet.
