Filling
The water tank can be filled with a hose pipe via fillers located on either side of the body
or, alternatively, hydrant connection is provided adjacent to the nozzle trunking. This facility
is provided with a filter cartridge to prevent particles entering the tank. The filter is mounted
vertically allowing particles to be back washed and fall out once the hydrant hose is released.
Secondary Water Filter
1 Before dismantling the filter, activate the
shut off valve actuator (A) located in the filter
housing. It has a bayonet type mechanism.
Press in and turn anticlockwise to activate
the shut off valve.
2 To access filter element, unscrew the
securing ring (B) around the outside of the
filter housing (C) and remove. The filter
element (D) can now be withdrawn.
3 Clean the element by flushing with clean
water or an air line from the inside out.
Visually inspect the element for damage and replace if necessary.
4 When reassembling the filter, ensure that the filter element is correctly located in the filter
housing before tightening the securing ring.
5 Refit the shut off valve actuator. Pushing in and turn clockwise to open the valve ready for
use.
The Water System Is Protected By Both A Primary And Secondary Water Filter.
Primary Filter
The primary filter is located within the water tank attached to the underside of the body.
Its purpose is to prevent foreign particles entering the water system which could cause
malfunction of the water system. Access to filter (A) is gained by first draining the tank using
the flushing valve located on the side of the body, raise the body and engage the safety
prop. Unscrew the cap (B) to reveal the filter attached.
The filter can be cleaned in situ or, preferably,
removed from the cover and washed under a
tap from inside to out. The cover is sealed with
a sealing washer (C) and it is wise when refitting
the cover to clean both cover and the washer
thoroughly and then smear with grease. The
grease will help retain the sealing washer.
Periodically, whilst cleaning the filter, it is advisable
to flush out the tank. This is done by leaving off the
cap, lowering the body and using a high pressure
hose through the two port holes in the rear panel adjacent to the rear door. When replacing
the port hole caps, again smear with grease and ensure the sealing washer is present. Refit
the filter, cap, and close flushing valve(s).
