Pressurized-water system HF1208, HF2408, HF1219, HF2419
Winter Preparation
The whole drinking water system, including the pressurized
water system, should always be drained. Never fill the drinking
water system with anti-freeze, it is very poisonous!
Draining the pressurized water system
Remove the snap connector from the pump (drawing 3). Allow
the pipes and pressure tank to drain empty. Then let the pump
run for a time without any water input.
Maintenance
Cleaning the Water Filter
Unscrew and remove the cover (drawing 4). Clean the filter ele-
ment thus exposed. Refit the cover.
Checking and pressurizing Pre-pressure and Air
Cushion
Remove the protective cap, turn to the left and check pressure
with a tyre air pressure meter.
Reduce pressure: Push the Schräder valve pin in; air will now
escape.
Increase pressure: Connect a car tyre pump to the valve and
bring the air cushion to the required pressure.
Replacing the Membrane
Under normal circumstances the membrane should never
need replacement. However if it does leak, replace as follows:
Ensure that the whole system is de-pressurized. Remove the
hose between pump and T-piece, remove the 6 bolts holding
the flange to the top of the tank and remove flange complete
with T-piece. Remove the old membrane, refit a new one and
reassemble in reverse order to the above.
