9.0 Installation of pump station
9.5 Installing the pump station - positioning
It is usual to install the hydraulic station and solar controller
near to the solar cylinder. However this does not have to be
the case, the hydraulic station can be installed anywhere
convenient on the solar primary pipework although adequate
access will be necessary for commissioning and maintenance.
The solar controller should be accessible for system
operational monitoring. Also if an auxiliary heating source is to
be controlled by the solar controller, consideration must be
given to the accessibility of the controls to allow the user to
make adjustments to the settings. If not in close
proximity to the solar cylinder it will be necessary to extend
the solar cylinder temperature sensor cable, refer to section
10.7 for details of how to do this. It is recommended that the
upper mounting bracket of the hydraulic station is positioned
for ease of access and operation of the controls, see Fig. 18.
When choosing the site for the hydraulic station provision of a
discharge pipe from the safety group and the location of the
solar expansion vessel must be considered.
9.6 Installing the wall brackets and pump station
Remove the front insulation moulding (Fig 19. Item 1) by
pulling forward whilst holding the solar controller moulding (Fig
19. Item 2) in place. Carefully remove the solar controller
mounting by pulling forward and disconnect the pump cable
connector (Fig 19. Item 3). Place the pump assembly on the
wall at the desired location and mark the fixing positions
through the holes in the mounting brackets. Remove the
hydraulic assembly from the mounting brackets (Fig 19. Item 4)
4
and remove rear insulation moulding (Fig 19. Item 5). Drill and
plug the mounting positions and secure the mounting brackets
into position using the fixings provided.These fixings may not
be suitable for all wall materials. Push the rear insulation
moulding over the wall brackets and refit the hydraulic
assembly (Fig 19. Item 6) to the mounting clips on the wall
brackets.
