MAINTENANCE
Make sure the pump is disconnected from electric power supply before performing maintenance
procedures.
Cleaning the filter
The filter (10) should be cleaned periodically or when foreign matter is visible through the transparent
filter cover (2).
1. Close suction and discharge valves (not included).
2. Open and remove the transparent filter cover (2) by turning
anti-clockwise (Fig. 19).
3. Remove the filter (10) from the filter cavity (Fig. 20) and clean the filter (10)
thoroughly with water.
4. Inspect the pre-filter seal (O-ring) before replacing the transparent filter
cover (2). Ensure that it is not worn or damaged, if damaged, replace the
pre-filter seal.
5. Place the filter (10) back into the filter cavity.
6. Close the transparent filter cover (2) by turning clockwise.
Note:
Replacement pre-filter seals are available through Bunnings Warehouse Special Orders desk.
These seals are consumable, wearing components and will wear with time. These seals are not covered
under warranty.
Cleaning the Pump Housing
Use a moist cloth to wipe down the pump housing (4). Allow to dry thoroughly before storing in a dry
location that is protected from bad weather conditions.
If the pump is not going to be used for a long period of time, it is advisable to rinse with water and empty
the pressure tank (6) (see operation section on emptying the pressure tank). Ensure the pump is
completely dry before storing.
Adjusting the Tank Pressure
IMPORTANT:
Ensure you completely empty the water bladder first using the drain screw (5).
Inside the pressure tank (6) is an expandable water bladder and an air
compartment, its maximum pressure should lie at approximately 1.3 bar
when no water is in the tank. Pumping water into the water bladder causes
the bladder to expand so that the pressure in the air compartment increases
to switch-off level. If the air pressure is too low, you should increase it. To do
so, unscrew the air valve cover (12) from the end of the pressure tank (6)
(Fig. 21) and top up the pressure to the correct level (approx. 1.3 bar) using
an air pump with a guage at the air valve (13).
