The in-line filter screen should be cleaned periodically. To gain access to the In-Line Filter Assembly remove the
right side panel (viewed from the front of unit) of the Power Supply. Remove the filter screen by unscrewing the
filter holder from the In-Line Filter Assembly. Clean the filter screen by rinsing with hot soapy water. Remove soap
residue by rinsing with clean hot water. Be sure that all the soap has been removed and the screen is dry of water
before re-installing in the In-Line Filter Assembly.
5.04 Coolant Replacement Procedure
Replace coolant as follows:
1. Disconnect the system from main input power. At the bottom of the coolant tank, disconnect the coolant
line fitting and collect coolant in a disposable container.
2. Connect the system to main input power and turn it on to allow the pump to empty the tank. The pump will
run approximately for 20 seconds before the flow switch causes an interlock. This procedure may be
repeated a few times until the tank is completely empty.
3. Connect the coolant line fitting and fill the tank with fresh coolant until the right level is reached.
