2.1)

Procedure

*
Position the boiler squarely on the prepared base
*
Fit the correct accessories to the boiler connections
*
Connect the boiler to the pipework system
*
Connect the boiler to the isolated electrical supply
*
Fill the boiler with fresh, clean water
*
Check that the immersion heaters are electrically isolated from the
boiler. If the isolation is less than 2mega-ohms, the bridge must be
found and rectified.
*
Check the operation of the main control panel isolator, and of the
overloads serving the immersion heaters
*
Check the operation and the correct direction of rotation of the
circulating pump
*
Check, with the circulation pump stopped, that the water flow switch
over-rides the immersion heaters through their relays and also brings
on the relevant alarm light
* Check the setting and operation of the immersion heater step controls
* Switch off the immersion heaters using the main control panel isolator
* Check that all the cartridge fuses are sound
* Double check that all the immersion heaters receive the common
voltage. Repeat the check after several hours run. Any defect in
voltage can destroy the heaters and invalidate the guarantee.
