HydroTap Installation and Operating Instructions_Commercial_BCH 4in1_BH 3in1_October 2012_V1.05 Page 10 of 24
Step D- Connecting the (Boiling / Chilled) HydroTap outlet
Note: Included in the installation pack are adhesive backed silicon buffers. If
air vents are not installed in the cupboards housing the HydroTap, the buffers
must be placed on the inside edge of the cupboard door to create a slight gap
ensuring a minimum airflow. Failure to do this may cause the HydroTap to
overheat and operate inefficiently.
Model BCH (4-in-1)
Measure and trim the blue tube and connect it to the chilled water outlet
located on the top front, right hand side of the undersink unit. Use spring
clamps provided to secure the hose.
Measure and trim the red marked tube and connect it to the hot water outlet
located on the top centre, right hand side of the undersink unit. Use spring
clamps provided to secure the hose.
Measure and trim the unmarked tube and connect it to the vent outlet located
on the top centre, left hand side the top of the undersink unit. Use spring
clamps provided to secure the hose.
NOTE: All tubes must have a continuous fall back to the undersink unit.
Connect the tap USB connector to the USB port on the undersink unit. Orient
the USB plug carefully and connect, do not force the plug. Once connected, fix
the cable to the wall, ensure it is away from any possible water splashes and
is off the floor.
NOTE: When trimming any silicon tubes trim to minimum length, do not loop
any excess or allow kinking of the tubes. When connecting, slide the tube over
the pipe at least 25mm. There are black plastic clamps provided on the boiling
and chilled hoses to choke the flow if required. Only choke the flow if it is
excessively strong.
Model BH (3-in-1)
Measure and trim the red marked tube and connect it to the hot water outlet,
on the top of the undersink unit. Use spring clamps provided to secure the
hose.
Measure and trim the unmarked tube and connect it to the vent outlet on the
top of the undersink unit. Use spring clamps provided to secure the hose.
NOTE: Both tubes must have a continuous fall back to the undersink unit.
Connect the tap USB connector to the USB port on the undersink unit. Orient
the USB plug carefully and connect, do not force the plug. Once connected, fix
the cable to the wall, ensure it is away from any possible water splashes and
is off the floor. Fasten the tap body to the sink using the bolt & plate system
provided.
Step E - Connecting an external filter.
(Not supplied as standard equipment).
To combat the build up of lime scale, a high performance external filter kit
may be ordered from your Zip service provider.
NOTE:- When fitted, the external filter will supply filtered water only for the Hot
tank. The internal filter will continue to supply filtered water for the cold tank.
• The external filter may require the inlet water pressure to be regulated to
lower than 6 bar. In this case a 3.5 bar Pressure Reduction Valve will be
required.
