TO CHECK OR ADJUST THE PRESET OUTLET TEMPERATURE SETTING
The temperature settings will be displayed on the LED display. The preset outlet temperature settings are:
874 series
38°C, 40°C, 42°C, 43°C, 45°C, 50°C, 55°C, 60°C, 70°C, 75°C
Notes:
Setting the preset outlet temperature to less than 50°C IS NOT RECOMMENDED. If the temperature
is adjusted to less than 50°C the water saving function of the water heater will not operate resulting in nil
water saving.
It is necessary to have the electrical supply to the water heater switched on during stages of checking or
adjusting the preset outlet temperature setting procedure.
Warning:
The removal of the front panel will expose 240 Volt wiring. Take care not to touch wiring
terminals. The adjustment must be carried out by a qualified person.
Warning:
This procedure will involve the adjustment of dip switches. Adjustment of a dip switch should
only be made with an insulated tool.
To check or adjust the preset outlet temperature setting:
1.
Switch off the electrical supply at the power outlet to the water heater.
2.
Remove the screws holding the front panel to the jacket.
3.
Gently disengage the front panel and pull forward to remove from the
water heater.
4.
Switch on the electrical supply at the power outlet to the water heater.
5.
Switch dip switches 3 and 4 to the on (up) position on the DIP 1 set of
DIP switches on the I.C. Board.
The current preset outlet temperature setting will show on the LED
display.
If the temperature displayed on the LED display is the desired preset
outlet temperature setting, then proceed to step 7, as no further
adjustment is necessary.
6.
Press the MAX button to increase or the MIN button to decrease the
preset outlet temperature setting.
Each press of the MAX or MIN button will increase or decrease the
preset temperature by one increment.
The MAX and MIN buttons are located underneath the DIP 1 and
DIP 2 set of DIP switches.
The recommended temperature increments are 50, 55, 60, 70, 75
(setting to less than 50°C will render the water saving function
inoperative).
7.
Switch dip switches 3 and 4 to the off (down) position.
The LED display will go blank. The preset outlet temperature setting is
now set.
8.
Switch off the electrical supply at the power outlet to the water heater.
9.
Refit the front panel and screws to the water heater.
