Commissioning & operation
1. Check that all ‘Requirements’ under ‘Installation’ have been met.
2. Check that all water and electrical connections are correct and tight.
3. Open a hot water tap.
4.
Open the water mains isolating valve and allow the heater to fill.
5. Close the hot water tap when water starts to flow from it.(The heater vessel should now
be full).
6. Check for leaks and rectify as necessary.
7.
Manually operate the Expansion Relief Valve and T&P Valve if fitted to ensure free water
flow through the discharge pipe by turning the knob to the left and holding it in the open
position.
8. Set the temperature control knob to the required position. The ‘E’ position with a water
temperature of 55°C is recommended for economical operation while minimising lime-
scale deposits and thermal losses.
Note
:
• Rotating the temperature control knob varies the temperature over the range 7°C to
75°C.
• The maximum temperature can be limited by prising the front cover (lens) off the
temperature control knob and re-positioning the limit pin as shown in (fig.3) below,
from ‘0’ to position ‘A’ max 55°C, ‘B’ max 45°C, or ‘C’ max 35°C.
• Hot water at 55°C or more can scald.
Note .
To protect the water heater from freezing, the temperature control knob may be set
when a stored water temperature of approximately 7°C will be maintained while the
heater is connected to the power supply.
NB :This protection does not extend to the pipe work and fittings.
