HydroTap Installation and Operating Instructions
Installation procedure
continued
Step B - Installing the undersink unit
SPECIAL NOTE: The HydroTap undersink units are heavy, take note of the
weights listed in the table on page 4. 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) to
the cold water tee piece (see Pages 10-13). Flush the hose prior to connecting
to the cold water inlet at the rear of the unit.
Position the HydroTap undersink unit as close as possible to directly beneath
the HydroTap tap head.
The connection tubes supplied with the tap head assembly CANNOT be
lengthened.
Leave at least a 50 mm air-gap without obstruction on each side of the unit
and 65mm at the rear
Step C - 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: Vented
Connect the 3 braided hoses to the rear of the undersink unit as shown in
pages 12 -13 . Make sure the connections at the venturi are all adequately
secured. Tighten the elbow at the back as this elbow has been left loose for
final orientation by the installer.
When fitting the BH3 braided hose to the tap assembly it is necessary to
tighten the hose firmly by hand. Excess force may damage the O - rings.
Check these joints for leaks during initial operation.
Measure and trim the blue silicon 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 silicon 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 clear silicon 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 1:
All tubes must have a continuous fall back to the undersink unit.
NOTE 2:
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.
NOTE :
New hose sets supplied with the
unit should be used. Do not use
old hose sets.
NOTE:
1-
The braided hose (BH1) with the
BLUE ring markings must be fitted to
the Right Hand Side when the tap is
oriented as shown above. Fit the RED
marked braided hose (BH2) to the LHS.
2-
The braided hose (BH3) from the
venturi is fitted to the central position.
3
- The clear silicon tube is the vent
line from the undersink unit to the tap.
