The air is then reheated by the I heat of compression as it passes through the centrifugal blower and is delivered at temp- eratures of 90 degrees F and above.
36. PS4 and PS5 are staged to control Sl, S2, Ul, and U2 so that, as the conditioned air I heat load decreases, the precooler evaporator heat exchange surface area and compressor capacity can be reduced to match the system operating point to the heat load.

To prevent injury to personnel, use care when servicing the refrigera-
tion system. High pressures are pre- sent which could cause serious in- jury. If a refrigerant leak is sus- pected, provide adequate ventilation and be careful not to inhale refrig- erant vapors or allow any refrig- erant to contact the skin.
2. LEAK TEST.
a. Remove condenser fan panel assembly (WP 008 00).
To prevent injury to personnel, be careful when working near rotating components.
b. Check all refrigerant Iittings, couplings, and valves for leaks.
c. Mark all spots where leaks are detected
d. If no leaks exist at receiver, pump down refrigerant system (this WP, paragraph 3); if leaks exist at receiver, open system to blow the charge.
e. Repair leaks (NAVSEA 0900-LP-001-7000)

Support Equipment Required
None
a. Determine cause of burnout and make any necessary corrections. Check for blown fuses, welded starter contacts, welded overload contacts, burned out heater elements. Check comwessor ter- minal plate for burned or damaged terminals and insulation, shorted or grounded terminals. Check unit wiring and power supply for possible grounds or shorts. Check unit wiring for loose power con- nections. Check for high or low voltage.
Materials Required h. Close compressor suction and discharge serv-
ice valves and bleed refrigerant from compressor. Specilicationor Pm-t Number No”e”clat”re
Refrigerant (R-113)
e. Remove suction and d&ha.-ge shut-off valve bolts and all other connections to damaged corn- pressor. Remove damaged compressor (WP 008 00).
d. Release contaminated refrigerant from sys- tem by opening compressor suction and discharge service valves. Care should be taken to release the refrigerant slowly at first as the pressure within the system will be high.
Refrigerant is toxic. To avoid injury to personnel avoid breathing or exposure to skin or eyes. Do not expose refrigerant to open flame.
e. Replace filter drier core (WP 008 00).
f. Set main service circuit breaker. CBI, OFF.
Compressor burnout produces hydrochloric and hydroflouric acid residues throughout a refrigerant system. To avoid injury to personnel, avoid contact with acidilied refrigerant or acidified compressor oil. Wear rubber gloves and facial protection when working around acidified systems.
g. Open solenoid valves as follows:
(1) Open PRESSURE CONTROLSdoor.
(2) Remove covers from PS4. PS5, and PS6.
(3) Using three jumper wires, connect terminals I, and M2 of PSd and PS5 and terminals L and Ml of PS6.
(4) Set MODE switch to COOL
To prevent injury to personnel or damage to equipment, electrical power must be disconnected when working inside electrical controls, pressure controls. or instrument panel.
(5) Open INSTRUMENT panel by turning grip latches countereloekwise.
(6) Apply a IIOVAC, 60 Hz, single phase power supply across terminal block location TBI-1 and ground (TBl-6 through TBl-11). Solenoid valves Sl through S6 will open.
NOTE
This procedure is difficult, time- consuming and expensive. This procedure should be performed in the Field only if depot level facilities are unavailable or inaccessible.
h. Close compressor suction service valve
i. Connect R-113 refrigerant supply to com- pressor discharge service valve. Open refrigerant supply valve and flood refrigerant system.
j. Place catchpan or bucket under hole in lloor- board.
