CAUTION

Handle and dispose of the used coolant per recom-
mended procedures.

2. Drain the coolant from the Coolant Reservoir per

the following procedure:

a. Disconnect the Input Hose at the Rear Panel

Filter Assembly. The hose goes from the bot-

catch the coolant as it flows from the reservoir.
Only enough needs to be removed so that the
level is below the In-Line Filter/Flow Switch
Assembly hole located on the end of the reser-
voir.

NOTE

Do Not run the pump as the coolant will gravity
feed from the reservoir.

Line Filter Assembly.

Switch Assembly.

5. Install the replacement In-Line Filter Assembly by
