Calibration
The Nulo shower valve has a factory set outlet temperature of 38˚C via the security setting.
This is based on a balanced supply pressure and a stable hot water inlet temperature of 65˚C.
However, the calibration point
MUST
be checked and re-set as necessary to suit site conditions.
Care must be taken when re-calibrating the valve as
INCORRECT CALIBRATION CAN CAUSE
INJURY.
• Remove the cover cap (2), the retaining screw (3), spring washer (4), brass spacer (5),
temperature control knob (6), the control knob bush (8) and the temperature stop ring (10)
paying attention to the position before removal.
• Fully open the flow control (1) and allow the outlet temperature to stabilise from the bottom
outlet.
• Temporarily refit the control knob bush (8) and control knob (6) and using a digital thermometer
it is possible to increase or reduce the mixed water outlet temperature until 38˚C is
re-established, by slowly rotating the control knob.
• Remove the control knob bush (8) and control knob (6) and refit the temperature stop ring (10)
onto the splined section of the cartridge when 38˚C is achieved. Refit the temperature stop ring
as per the position before removal.
• Refit the temperature control knob in the reverse order ensuring that 38˚C on the shower body
is in line with the security setting of the control knob.
PLEASE NOTE THAT ONCE CALIBRATED, THE SECURITY SETTING WILL ONLY BE 38˚C
UNDER THE SUPPLY CONDITIONS USED FOR CALIBRATION.
