6. Installation
6.1 General
After reading the previous sections in this booklet and choosing a good location for the unit please install, paying attention to the
following hydraulic, electrical and commissioning sections.
Boiler selection
#
The boiler should have a control thermostat and non self-resetting thermal cut-out and be compatible with unvented storage water
heaters.
#
Where use of a boiler without a thermal cut-out is unavoidable a "low head" open vented primary circuit should be used.
The feed and expansion cistern head above the cylinder should not exceed 2.5m.
#
Can be a sealed system or open vented type - maximum primary pressure 3 bar.
#
The boiler cannot be vented through the cylinder.
6.2 Water connections
WARNING
#
Under no circumstances should the factory fitted temperature/pressure relief valve be removed other than by a competent person.
To do so will invalidate any guarantee or claim.
#
The cold water combination valve assembly must be fitted on the mains water supply to the cylinder.
#
No control or safety valves should be tampered with or used for any other purpose.
#
The discharge pipe should not be blocked or used for any other purpose.
#
The tundish should not be located adjacent to any electrical components.
Refer to the installation schematic, fig 9 for details on the pipework layout. Specific details for the discharge pipework layout is also provided
in figure 11.
#
All pipe fittings are made via BSP female pipe connections directly to the unit.
#
A stopcock or servicing valve should be incorporated into the cold water supply to enable the cylinder and its associated controls to be
isolated and serviced (not supplied).
#
The expansion vessel must be connected between the cold water combination valve and the cylinder.
