2.2 SITING THE PREMIER PLUS SYSTEMFIT

The Premier Plus SystemFit unit must be vertically oor mounted. It can be placed anywhere con-

venient provided the discharge pipe(s) from its safety valves can be correctly installed. Areas that

are subject to freezing must be avoided. Ensure that the oor is of sufcient strength to support

the “full” weight of the unit (refer to Dimensions Tables on pages 30 and 31 for unit weights). Pipe

runs should be kept as short as possible for maximum economy. Access to associated controls,

immersion heaters and indirect controls (Note: indirect controls housing hinges open to the left

hand side) should be possible for servicing and maintenance of the system.

To aid installation the Premier Plus SystemFit is provided with lifting points located in the base

and top mouldings. A oor template is also provided to aid positioning.
