INSTALLATION

OMMISSIONING

• Press in the centre button on the front panel

marked ‘Switch’ for 5 seconds. The mode
indication on the display panel will change
from normal to Switch and will flash. Check
that current is being drawn (it should be
about 26 amp) with the aid of a clamp meter
on the supplies to the element.

• If a suitable meter is not available once the

bath full of hot water has been drawn from
the appliance the store temperature should
be noted. With no further demand a rise in
store temperature of 5 - 10°C in about 15 - 20
minutes (dependent on store size) should be
observed. Display segment V2.2 will be on
whilst ‘Switch’ is working.

• Switch the boiler back on and set channel 1

(HW) of the clock as required.

Once the system is finally filled turn down the servicing valve for the ballvalve
in the F & E cistern to the point where the warning/overflow will cope with the
discharge arising from a ballvalve failure.

Cleansing Hot/Cold Water System Treatment

Fully flush and if necessary chlorinate the hot and cold water system in accordance
with the recommendations in the Model Water Byelaws and BS 6700.

Note: Incorrect chlorination will damage the plate heat exchanger so care must
be taken that the system is fully flushed. Failure to do this will lead to problems
that are not covered by the appliance warranty.

Commissioning the BoilerMate/Primary System

For maximum system efficiency the store thermostat must be in control of the boiler i.e. the
boiler will operate to suit the demands of the store thermostat and not on its own integral
thermostat. Once commissioned, the appliance will operate automatically on its controls.

• The operation of the BoilerMate A-Class OV SOL appliance is controlled by the main

appliance control board. The functions can be checked on the display window on the front
of the appliance or on the 2 digit display on the appliance control board. The following
descriptions generally refer to the 2 digit display but details of the operation of the display
window on the front of the appliance are covered on pages 13-14 of these instructions.
Either can be used. The demands are shown on display 2 (left hand) and the resultant
actions on display 1 (right hand).

• A diagram and table showing the function of each LED is shown opposite.

• Set the BoilerMate A-Class OV SOL power switch to on (the dot in the right hand

corner of display 2 will flash).

• Set the hot water channel (1) on the digital clock on the front of the appliance to

‘Continuous Operation Mode’. V1.1, H1.1 and H1.2 will be on.

• Set the heating channel (2) on the digital clock to the off position.

• Set the boiler power switch to the on position and the thermostat to maximum

(H2.3 and V2.1 will be on).

• Commission the boiler as per the boiler manufacturers instructions, making sure

any air is vented from the primary circuit.

• Check that the store sensor reaches its set point (77°C) and switches off the boiler.

The primary pump will continue to run for a period of time to ensure the boiler
cools down safely and any residual heat is transferred to the BoilerMate A-Class
OV SOL (V2.1 will go off but H2.3 will remain on for 3 minutes).

• Check and adjust the speed of the boiler pump to provide a differential temperature

of less than 8°C across the primary flow and return (with the heating off).

• Once the boiler/primary circuit is commissioned, the operation of the ‘Switch’

emergency electric back up system can be checked.

• Switch off the boiler.

• Draw a bath full of hot water to lower the store temperature and allow ‘Switch’ to

operate.

• Switch on MCB1 and MCB2 which will break the warning label and allow power to

be provided to the system.
