Fig 8 -
NT 1500-XT Power Shower
The valve allows the maximum showering temperature to be set at a safe level,
preventing accidental scalding. This setting should be made during commissioning
and will require that the hot water cylinder is at its normal operating temperature.
IMPORTANT:
•
The handset must be in the spray mode.
•
We recommend the reading of User Instructions before proceeding further. This
will familiarise you with the operation of the shower.
Temperature Adjustment
Procedure:
Turn the brass mixer valve spindle fully clockwise, and then anti-clockwise until the
black line on the spindle is aligned with the groove on the mixer body, and fit the
control knob in the fully cold position. Check that it is correctly fitted by turning fully
clockwise to the stop, pull the knob off and check that the black line and groove are
aligned. Adjust if necessary. This sets the shower temperature to 38-40ºC, with the
control knob pointing to “12 o’clock”, if the hot water is at the recommended 60ºC.
Commissioning
1) Connect the shower hose – without the handset – to the outlet from the unit.
2) Turn on the hot and cold water isolating valves, and the electricity-isolating
switch, and place the open end of the shower hose in the shower tray or bath.
3) Set the temperature control knob to cold, fully clockwise, and press the
“Stop/Start” button.
4) Cold water will flow from the hose, and this should be allowed to continue for 2
minutes, after which time the control knob may be turned to the “12 o’clock” position.
Allow the water to run for a few minutes to stabilise the hot water flow, and then
check that the water is at a comfortable showering temperature.
5) If it is too hot or too cold, turn off the electricity-isolating switch, pull off the
control knob,and adjust the brass spindle anti-clockwise to increase the temperature
- clockwise to decrease. Replace the knob in the “12 o’clock” position, switch the
electricity on, and check the water temperature. Readjust as necessary until a
satisfactory temperature is achieved.
6) Pass the shower hose through the hole in the soap dish and, using the rubber sealing
washer supplied, fit the showerhead to the hose and place the showerhead in the
handset holder.
7) Press the Stop/Start button. Water flows from the shower head under the gravity
pressure from the storage tank.
Press the Shower Boost button and the
pump starts, boosting the shower pressure.
