Page 3 Determine the best location for the unit in the walk-in cooler or freezer. Consider the air pat- tern required to cover the entire space. For High Sierra Systems with two unit coolers, locate the unit coolers so that the piping runs from the suction and liquid line tees are equal in size and length.

A pumpdown cycle is mandatory for all systems. For both Sierra and High Sierra systems, a liquid line solenoid is factory installed and wired to each unit cooler terminal board (multiple evap systems receive multiple solenoid valves). Follow the system wiring diagram (provided in the condensing unit).

MULTIPLE EVAPORATOR PIPING High Sierra systems involving multiple evaporators require that piping runs be of equal length to each evaporator. The line runs must be of equivelent length from the bull-head tees to each unit cooler.
Page 7: Evacuation
AREA 2: From the liquid line module to the liquid line solenoid; connecting to the liquid line “King” valve port gets this area on Sierra system. The connection will not properly evacuate area 1, above, since evacuation would have to be pulled through the check valve in the module, which will have about 1 PSI restriction.

All fan motors are life lubricated and do not require periodic oiling. Do not use ammonia or other cleaning agents that are corrosive or react with Copper or Aluminum. If the liquid line filter is replaced High Sierra system, it must be replaced with a Bi-Flow filter.

Page 10: High Sierra Sequence Of Operations
HIGH SIERRA - Sequence of operation. Refrigeration cycle The High Sierra counter flow defrost system is unique in design. It operates like most conventional systems during the refrigeration cycle. As cooling is called for, the compressor, condenser fan(s), evaporator fans and liquid line solenoid valve are all energized.

Later model units have the drain pan loops welded to the drain pan. 3. The High Sierra system has a time initiated and pressure terminated defrost. The pressure switch is factory set at 250# Cut In pressure and 200# Cut Out pressure. If the 250 pound setting does not clear the coil, the setting may be raised to a higher pressure, but no higher than 300 pounds (use high pressure gauge for this check).
