After filling the installation with water in the previous section please follow the following steps to complete the installation of the unit.
WARNING
DO NOT operate the immersion heaters or primary circuit until the cylinder has been filled with water.
7.2 Checklist before commissioning
#
Check all water connections for leaks and rectify as necessary.
#
Turn off mains water supply.
#
Remove the pressure reducing valve head work to access the strainer mesh, clean and re-fit.
#
Turn the water supply back on.
#
Manually open, for a few seconds, each relief valve in turn, checking that water is discharged and runs freely through the tundish and out
at the discharge point.
#
Ensure that the valve(s) reseat satisfactorily.
7.3 Commissioning procedure
Auxiliary
#
Switch on electrical supply to the immersion heater(s) and allow the cylinder to heat up to normal working temperature (65°C
recommended).
#
If necessary the temperature can be adjusted by inserting a flat bladed screwdriver in the adjustment spindle on front of the immersion
heater thermostat and rotating.
The adjustment represents a temperature range of 10°C to 80°C.
#
Check the operation of thermostat(s) and that no water has issued from the expansion relief valve or temperature/pressure relief valve
during the heating cycle.
Primary circuit
#
Fill the indirect (primary) circuit following the boiler manufacturer's commissioning instructions.
#
To ensure the cylinder primary heat exchanger is filled, the 2 port motorised valve (supplied) should be manually opened by moving the
lever on the motor housing to the MANUAL setting. When the primary circuit is full return the lever to the AUTOMATIC position.
#
Switch on the boiler, ensure the programmer is set to Hot Water and allow the cylinder to heat up to a normal working temperature 65°C
(recommended).
