WARNING
The drain hose heaters operate from high voltage sources. Make sure that power
cables are disconnected from the MTRCS and that the refrigeration unit is shut down
before performing maintenance on the unit. Failure to comply with this warning can
result in serious injury or death to personnel.

NOTE
There are several individual drain hoses used between both evaporators to route
condensate from evaporator drip pans to the container walls for outside drainage.
This task can be used to replace any drain hose. Some hoses may be secured to the
container using clamps and attaching hardware that will need to be removed as
required to remove the drain hose.
2. Disconnect both sides of damaged drain hose (Figure 1, Item 1).
3. Remove screws (Figure 1, Item 2), lock washers (Figure 1, Item 3), washers (Figure 1, Item 4), and clamps
