Section 5: Maintenance; Coolant Filter Cleaning Procedure - Thermal Dynamics PAK 200 Operating Manual

Perform the following checks periodically to ensure proper system performance.

5.01 Coolant Filter Cleaning Procedure

Periodic cleaning of the coolant filter ensures maximum coolant flow efficiency. Poor coolant flow causes inef-
ficient torch parts cooling with consequent faster consumable wear.
Clean the coolant filter as follows:
1. Disconnect system from maintenance input power.
2. Unscrew and remove the filter bowl by hand. Be sure to keep the O-ring.
3. Remove and clean the filter. Re-install the bowl, tightening it by hand. Be sure the O-ring is in place.
4. Turn the system on and check for leaks.
