Maintenance
Filters
If the pump is running but no pressure is building in the test cell, this may
indicate that a filter is clogged. Each cell has a filter on the supply line outside
the cabinet. There is also a filter on the main water supply inside the cabinet.
1. Make sure there is no pressure on the system.
2. Set the “PRESSURE” switch to “OFF”.
3. Turn the Water Supply valve to “DRAIN”.
4. To access the filter on the water supply, remove the panel on the left-hand
side of the unit. The filter is near the base plate at the back of the cabinet.
5. Unscrew the hexagonal fitting from the filter housing. Make a note of the
direction of the arrow on the filter.
6. Remove the filter element and clean it thoroughly, removing any debris.
7. Put the filter element back in and screw it back onto the filter housing. Make
sure the arrow on the filter is pointing away from the back of the cabinet.
