Zip FlushMaster Pearl Installation & Maintenance Instructions - 82902 - January 2012 v1.00
Maintenance Instructions
Cleaning
Keep the slot openings in the face of the sensor clear of dirt.
Never clean the case with strong or abrasive cleaners.
Wipe with a soft cloth, warm water and dish washing liquid.
Never hose or spray any part of the flushing system.
Where the Zip FlushMaster is powered by a long life lithium battery a life of up
to three years can be anticipated depending on frequency of activation.
However to avoid the inconvenience associated with any malfunction of the
flushing system, it is recommended that both the battery and the latching valve
diaphragm be replaced annually.
Where the optional power pack is fitted, the power must be turned off at the
power point before any form of maintenance is attempted.
Battery Replacement
Remove protective cover from sensor housing, locate battery holder.
Remove cover from battery holder and remove existing battery.
Replace existing battery with lithium cell type CRP2 / 223A only (Zip product
code 90098). Reset the Fill and Delay times (see notes on page 8 and 9).
Replace cover on battery holder and replace cover on sensor housing.
Battery low
When the battery voltage becomes low, the detection LED on front of unit
will flash both Green and Red (as shown). This will continue until there is not
enough power to open and close the valve. At this point the valve will close
and the detection LED will only flash Red (as shown). At this stage the battery
must be changed.
Valve Diaphragm Replacement
Isolate the water supply.
Remove fixing clip on top of latching valve coil by levering up clip with screw
driver and clicking back until clip releases from shaft.
Lift coil, spring clip and spacer from latching valve shaft.
Carefully undo the 4 screws retaining the valve housing. When the last screw
is about to be released, grip the valve body and top section as it is spring
loaded.
Carefully separate the top section containing the spring and plungers from the
lower body. The diaphragm should now be visible. Lift it out of position.
Remove the centre plastic piece from the rubber diaphram. Fit the new
diaphram to the plastic centre. Replace it in the same orientation.
Re-assemble in the reverse of above. Note the position of all parts in the
diaphragm for correct assembly. To order quote Zip part number 90279
