Installation Procedure
continued
Step B - Installing the (Hot / Cold) Mixer tap outlet
(see P20 options)
The approved vented tapware, as supplied must be used. It is advisable to
fit the tap to the sink before installing the undersink unit. Do not dismantle
the assembled tap body during installation. Mixer taps are factory tested and
sealed to provide optimum performance.
The sqaure tap option will require the spout to be fitted to the the tap body.
Carefully insert the spout into the tap body and push fully home. Tighten the
grub screw using the supplied Hex Key. Do not overtighten the grub screw, the
spout should be able to swivel without interference from the grub screw.
Before connection, it is recommended to flush water supply pipes thoroughly
to remove any silt or fines.
1. Make sure the tap location will allow the nozzle to drain into the sink.
2. Cut a 35mm hole in the bench / sink top.
3. Screw the 2 Braided hoses to the underside of the mixer tap, ensure that
each are firmly attached and in the correct colour or marking sequence.
See the diagram below for correct orientation.
4. Fasten the mixer tap body to the sink using the bolt & plate system
provided.
5. After the tap has been secured in place, screw the 1/2” tube (Fig. A-6) into
the remaining position on the underside of the mixer tap.
6. Connect the unmarked braided hose to the incoming cold water supply
using the tee piece (Fig. A-3) and restrictaflow (Fig. A-4).
7. Connect the clear hose to the top of the venturi (Fig. A-1) and join the
other end to the check valve (Fig. A-5) and connection pipe (Fig. A-6).
8. Connect the braided hose with a BLUE band to the elbow (Fig. A-2) on the
lower end of the venturi (Fig. A-1).
Step C - Installing the undersink unit
SPECIAL NOTE: The HydroTap undersink units are heavy, take note of the
weights listed in the table on page 7. If you think you cannot lift the unit
safely, get help and avoid possible injury.
Before positioning the heater connect the braided water inlet hose (supplied)
from the cold water tee piece (see item 3 in Fig.A) to the cold water inlet at the
rear of the unit.
Position the Zip HydroTap undersink unit as close as possible to directly
beneath the Zip HydroTap tap head. The connection tubes supplied with the
tap head assembly CANNOT be lengthened.
Leave at least a 50mm air-gap without obstruction on each side of the unit
and 65mm at the rear
The following instruction is CRITICAL:
Adjust both cupboard door hinges and attach the supplied rubber door buffers
to the doors to create a 4mm air-gap between the doors and the cupboard.
This is the minimum ventilation requirement for low usage installations.
Proper air circulation must be provided for all Boiling and Chilled models. The
system will operate correctly only if the recommended air gaps are achieved
during installation. A ventilation hole measuring 100mm must be cut into the
top half of the cupboard door to accommodate the air vent provided.
Make sure that the undersink unit ventilation grilles are not obstructed in any
way.
Cupboard ventilation for Boiling only models is recommended.
