Valves replacement HC797
NB: Where ball valves are to be replaced, it is recommended that the complete cartridge assembly is replaced, due to
the many small parts within.
The procedure is as follows;
1. Using a 19 mm spanner gently remove the cartridge.
2. If a ball valve cartridge is fitted remove the whole assembly and replace with a new one taking care to ensure that
the arrow is pointing in the direction of flow, (vertically upwards).
3. If lip valves are fitted, these can be replaced, once again ensuring that they are refitted the correct way up, with their
open end downwards, and the lip part in the direction of flow.
4. Refit the nipples and hose clamps to complete.
Valves cleaning HC897-HC997

1 With a little tool extract the valve cartridges from their seats
2 Pay attention not to loose the oring at the bottom of the cartridge
3 Clean the valve cartridge with clear water
4 For a complete cleaning it is possible to open the valve cartridge, be carefull with all the internal parts
5 Assemble again the valve cartridge following drawing fig. 11
6 Insert again the valves cartridges in their seats
Diaphragm and O-rings replacement
Proceed as follows:
1. Undo the 4 bolts with an hexagonal key.
2. Remove the pump head.
3. Remove the old O-ring from the head carefully using a small screw driver.
4. By hand, or with pliers if necessary unscrew the diaphragm, and replace with the new one. Hand tight only. Before
screwing the diaphragm into place, add a small quantity of Loctite® 222 onto the thread.
5. Refit the dosing head, tightening the head bolts sequentially and carefully to ensure an even airtight seal. Caution do
not over tighten. We also recommend adding a few drops of Loctite® 222 on to the thread of the screws that hold the
head.
