Leak Detector and Cabinet Drains
A leak detector is installed at the bottom of the cabinet. The leak detector is shown in
Figure 4-21 on page 4-48. It is mounted in the bottom cabinet near the center. The leak
detector consists of a small reservoir with a float. The TCU monitors this leak detector
to alert the system should a leak occur. A leak detection will cause the transmitter and
the pump to be shut off by activating the pump interlock signal. In order to reset the leak
detector the float must be removed and a drain plug removed. Removing the drain plug
allows the reservoir to drain into the drip pan at the bottom of the cabinet.
The cabinet can be emptied of coolant by opening the fittings at the end of the supply
and return side drain hoses. Use a 7/16" open end wrench to open the drain valves.
