[. . . ] All lights and display segments will be energized for five seconds at the start of the pre--trip. Since the unit cannot recognize lights and display failures, there are Pre--trip Initiated no test codes or results associated with this phase of pre--trip. Pass/Fail Criteria: Passes if current draw change is within the range specified. Pass/Fail Criteria: Passes if current draw change is within the range specified. Requirements: Water pressure switch or condenser fan switch input must be closed. Condenser Fan On Setup: Condenser fan is turned ON, a current draw test is done after 15 seconds. Pass/Fail Criteria: Passes if current draw change is within the range specified. Setup: Condenser fan is turned OFF, a current draw test is done after Condenser Fan Off 10 seconds. Pass/Fail Criteria: Passes if current draw change is within the range specified. Requirements: The unit must be equipped with a low speed evaporator fan, as determined by the Evaporator Fan speed select configuration variable. Low Speed Evaporator Fans NOTE If the unit is configured for single evaporator fan operation, Pre--trip tests P3--0, P3--1, P4--0 and P4--1 will fail immediately if Controller alarm codes AL11 or AL12 are active at the start of testing. Setup: The High Speed Evaporator fans will be turned on for 10 seconds, then off for two seconds, then the low speed evaporator fans are turned on. Pass/Fail Criteria: Passes if change in current draw is within the range specified. Fails if AL11 or AL12 activates during test for units operating with single fan only. Setup: The Low Speed Evaporator fan is turned off, a current draw test is done after 10 seconds. Pass/Fail Criteria: Passes if change in current draw is within the range specified. Fails if AL11 or AL12 activates during test for units operating with single fan only. Setup: The high speed evaporator fan is turned on, a current draw test is done after 60 seconds. Pass/Fail Criteria: Passes if change in current draw is within the range specified. Fails if AL11 or AL12 activates during test for units operating with single fan only. Setup: The high speed evaporator fan is turned off, a current draw test is done after 10 seconds. Pass/Fail Criteria: Passes if change in current draw is within the range specified. [. . . ] In order to protect the refrigeration unit from the highly corrosive sea atmosphere, or if the protective paint system is scratched or damaged, clean area to bare metal using a wire brush, emery paper or equivalent cleaning method. Immediately following cleaning, apply two-part epoxy paint to the area. Ensure that the unit power is off AND that the unit power plug is disconnected. If using factory provisioned wiring, remove the circuit breaker panel, with circuit breaker, from the control box. [. . . ]
