Changing the Filter Cartridge
1. Turn off the water flow to the cartridges at the valve, tank or tap.
2. Release the pressure by opening a tap downstream, or use the pressure relief
valve that is available in the lid of the filter housings.
3. Unscrew the bottom housing from the lid* and remove the used cartridge and
discard or wash. The inside of the filter housing and the lid should be checked for
cleanliness – they will usually need to be cleaned or sanitised – use hot water and
dishwashing liquid, thoroughly scrub all surfaces and then rinse.
4. Check that the o-ring is in position in the top of the housing base, lubricate with
a coating of suitable rubber lubricant, such as silicone. Place the o-ring into the
groove and with two fingers wipe the o-ring down into the groove. Do not wipe the
o-ring clean of lubricant after it has been properly seated in the groove because
the lubricant prevents “crawling” of the o-ring during the tightening of the lid and
thus prevents water leaks.
5. Screw the housing onto the lid and hand tighten. Open the tap downstream of the
filter and then open the inlet valve.
*The cartridge spanner supplied with the unit may help if the housing is tight.
CAUTION: The housing must be protected against freezing. Failure to do so
may result in cracking of the housing and water leakage.
WARNING: CAREFULLY AND GENTLY TIGHTEN WITH HOUSING SPANNER
as the bowl should only be tightened enough to avoid water leaking during
operation.
WARNING: If the water system is not going to be used for extended periods,
the cartridge should be removed from the housing and replaced with a new or
cleaned cartridge when the system is used again.
IMPORTANT: When opening the filter housing to install or change the
cartridge (element) it is common for the o-ring seal to lift out of the groove
and, at times, it may even stick to the cap.
CAUTION WHEN INSTALLING
1. This is a plastic product with a female thread. If you cross-thread a male
fitting, and/or you over pack with sealing tape, you could do permanent
damage.
2. If you use a tapered thread male fitting do not over tighten.
3. No warranty claims will be considered for damage due to incorrect installation.
