Filter Element Replacement
The coalescing filters are designed to trap dirt, moisture, oil, and other
debris that may damage the valve seals.
Before you start, make sure you have:
 A seal kit - Part number FC-FIL-0001
 1 x filter
 1 x filter bowl O-ring seal
 O-ring lubricant
Remove the coalescing filter
1. Degas the dispenser (see page 40).
2. Drain the coalescing filters (see page 46) if they have not been drained
already.
3. Unscrew the filter bowl(s) with a spanner on the 22mm hex nut at the
base of the filter bowl.
4. Remove the filter element.
5. Clean all oil and dirt off the components with a clean cloth.
Install the new coalescing filter
1. Insert the new filter element and lubricated filter bowl O-ring seal.
O-rings that are subjected to natural gas at high pressure
swell when exposed to air. Once swollen, they cannot be reused and
must be replaced.
Always use O-ring lubricant to prevent damage to the O-
rings.
2. Screw in the filter bowl(s)
3. Check the dispenser for leaks. (see page 45)
