Always refer to instructions from Enware before
disassembling any fitting. Spare part kits should be on
hand before any service of the tap is undertaken.
It is recommended that the trigger spray action be
periodically serviced. The maintenance interval will
depend on the frequency of use of the product, water
quality and the general environment.
Occasionally the handle screws should be checked
for tightness and a visual inspection made of all other
connections on the assembly. Ensure that the trigger
spray and hose, the wall bracket fixing to the wall and the
riser are secure, and tighten if necessary.
The trigger spray action can be maintained by simply
cleaning and lubricating the spring action, or by replacing
the SBA (cartridge). (For more detail, refer to FS729
trigger spray installation instructions.)
If re-greasing spindles, always use a silicon based food
machinery grade lubricant approved for use with fittings
that are in contact with potable water, such as Hydroseal
‘O’ Ring Lubricant or Molykote 111 silicone based grease.
SERVICING THE TRIGGER SPRAY
1. Using two (2) Phillips head screw drivers, undo the
locking screws from the handle and remove handle.
2. Using a 26mm spanner remove the cover dome and
red fibre washer from the spring loaded action. Clean
the inside of the cover dome. Use a dilute solution of
CLR if necessary. Remove all scale, grease and any
other residues.
3. Lightly grease the inside of the dome.
4. Pull out the piston from the SBA (stuffing box
assembly) and clean any scale or residues from the
spindle and button. Be careful not to damage the
O-rings.
5. Lightly grease the piston O-rings and push the piston
back into the SBA.
6. Depress piston to start water flow. Release piston
and check for leaks and that the water flow stops. If
there is no flow, or water does not stop, refer to the
troubleshooting guide. If the problem persists, service
kits or replacement SBA may be required.
7. With the red fibre body washer located over the SBA,
screw the cover dome back down onto the SBA.
8. Replace the handle and secure it with the hinge
screws.
9. Re-test trigger spray for correct operation.
