TM 5-4120-361-14 (7) Disconnect the pressure cutout switch flare nut from the refrigerant line  tee. (8) Remove the capillary tube grom- met in the back wall of the charging valve box and extract the capillary tube and flare nut through the opening. b. Testing. Test the pressure cut- out switch as described in paragraph 4-33. c. Installation. (1) Refer to figure 5-6 and in- stall capillary tube and grommet in charging  valve  box. (2) Mount pressure cutout switch to charging valve box. (3) Attach pressure cutout switch and charging valve flare nuts to refrig- eration  lines. (4) Refer to para 5-6 and leak test the refrigeration system. (5) Place charging valve box in po- sition and attach to housing. (6) Refer to wiring diagram (fig- ure 1-5 or figure 1-6) and attach elec- trical leads to pressure cutout switch. Attach service valve flare nuts. (7) Refer to figure 6-1 and purge tile refrigeration system. 1. Caution should be exer- cised with fluorocarbon re- frigerant gas (freons) as they can displace oxygen and there- by cause suffocation. 2. Personnel with a history or other evidence of cardiac rhythm abnormalities should be made aware of the potential for aggravation of existing cardiac rhythm abnormalities or the induction of arryth- mias, as a result of exposure to fluorocarbon refrigerant gases (freons). Such indivi- duals should be evaluated by local medical authorities be- fore working in environments where potential freon exposure may  occur. (8) Refer to figure 6-2 and charge the refrigeration system. (9) Refer to figure 4-20 and in- stall charging valve box access cover. 5-23. Pressure  Relief  Valve. a. General. In the event the re- frigerant system pressure should exceed 455 ± 10 psig, the pressure relief valve “pops off”   to restore normal pressure in the system. It may happen, that having once opened, the pressure relief valve does not totally seal closed when normal pressure is restored. In order not to constitute a continuous system leak, the valve must be replaced. b. Removal. (1) Refer to figure 4-4 and remove front  top  cover. 1. Caution should be exer- cised with fluorocarbon re- frigerant gas (freons) as they can displace oxygen and there- by cause suffocation. 2. Personnel with a history or other evidence of cardiac rhythm abnormalities should be made aware of the potential for aggravation of existing cardiac rhythm abnormalities or the induction of arryth- hmias,   as a result of exposure to fluorocarbon refrigerant gases  (freons). Such  indivi- duals should be evaluated by local medical authorities be- fore working in environments where potential freon exposure may occur. (2) Refer to figure 6-1 and dis- charge the refrigeration system. (3) Refer to figure 5-7 and remove the clamp around the pressure relief valve by removing the screw and washer that hold the clamp to the condenser fan housing. 5-16
