WIRING REQUIREMENTS
Pre-plumb wiring requirements are as per the diagram at the back of these instructions.
The factory assembled pre-plumb wiring detail is shown to the lower section of the connector block complete with the plug in connector
detail.
The upper section of the wiring to the connector block depicts connections to be created by the installer.
SYSTEM FILLING & COMMISSIONING
Once all plumbing and wiring is complete the primary system may be filled and flushed in the proprietary manner. Before filling ensure all
drain points and air valves etc. are fully closed. Fill via the filling loop ensuring the 2 port valves and the circulating pump isolation valves
are fully open.
Release all air from the auto air valve at the highest point of the pre-plumb pipework and also any other high points in the system. The
normal fill pressure is 1.0 bar to 1.5 bar - check both the boiler and radiator manufacturers requirements. During filling ensure all plumbing
connections including factory made connections are water tight, prior to leaving the factory the effects of transit may cause some
connections to subsequently leak upon filling, for which
we
can accept no responsibility for damage or inconvenience caused.
Once the system is full of water and devoid of air, turn on the boiler appliance and thermostats and heat both the hot water and the heating
circuits. The recommended hot water storage temperature is 60
o
C. Adjust the auto bypass valve as per the manufacturers instructions
included. Check all components are functioning correctly and that there are no leaks present.
