Defrost Pressure Switch –DPS (R404A Machines only).

The DPS is used to regulate the pressure

in the freezer during the harvest cycle. This pressure switch is wired in series with the D-valve (thaw
gas valve), which opens and closes during the harvest cycle to maintain 90 to 95 psig in the
evaporator.

Defrost Pressure Switch (DPS)

FIGURE 9-19

Pressure Relief Valves.

Pressure relief valves are installed on the freezer, receiver and the water

cooled condenser. These valves are designed to vent in emergency conditions. This ensures vessel
internal pressure does not exceed maximum allowable pressures.

PRESSURE RELIEF VALVES MUST BE REPLACED

AFTER 5 YEARS OF SERVICE.

BEFORE REPLACING RELIEF VALVE, REVIEW REQUIREMENTS PER

CURRENT LOCAL AND NATIONAL CODE.

VALVE REPLACEMENT SHOULD BE MADE BY PROPERLY TRAINED

PERSONNEL ONLY.

NOTE: IF REFIEF VALVE DISCHARGES, VALVE MUST BE REPLACED BECAUSE

SETTING OR SEAT TIGHTNESS MAY BE ALTERED.
