Mounting The Control Unit And Basin - Wallgate PSH-23 Product Manual

Product Manual PSH-23
4. The basin has one water outlet nozzle which may be connected to either hot
or cold water supplies as required, for which the pressure should be between
1 and 3 Bar (100kPa – 400kPa) (Dynamic). The unit is fitted with a solenoid
valve for operating the water.
5. The water supply can be connected to the solenoid with 15mm copper tube
and the addition of an isolation tap is recommended. The mains supply tap
supplied is recommended so that the water flow can be adjusted and for ease
of maintenance if the supply needs to be isolated.

Mounting the control unit and basin

1. Mark the fixing points on the wall taking care to maintain a minimum distance
between the unit and the basin so that the touch button cable will reach. Drill
holes, plug and mount the unit with the cables positioned at the bottom.
2. Assemble the M10 threaded wall fixings to the four threaded inserts on the
rear face of the basin ensuring they are fully inserted a minimum of 33mm and
then tighten each stud to a torque of 6Nm.
3. Position the basin into the wall aperture and fit the two wall brackets to the
M10 studs ensuring correct orientation of each bracket as shown on drawings
(pages 9 and 10).
4. Fit a washer and nut to each threaded stud hand tight only so that the position
of the basin can be checked to ensure it is level horizontally and vertically. It is
also vitally important to ensure the basin is flat to the wall face which must be
checked to ensure it is vertically level as this may severely affect the water
retention in the basin bowl and the basin drainage if the basin is not retained
in a vertical position.
5. Tighten the wall fixings in a circular pattern to ensure the basin is clamped
evenly to the wall and to a torque of 15Nm.
6. Apply a non-pick mastic such as Arbokol 1025 or Sikadur 33. The chamfer
around the basin where it meets the wall is provided for application of the
mastic which should be fully filled and shaped to give a ligature resistant
profile.
NOTE: It is important to tighten the wall fixings correctly using a torque wrench
to avoid distorting the metal brackets through excessive tightening.
