9.0 Installation of hydraulic station
9.5 Installing the hydraulic station - positioning
It is usual to install the hydraulic station and solar
differential temperature 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 differential controller should also be accessible
for system operational monitoring. If not in close
proximity to the solar cylinder it will be necessary to
extend the solar cylinder temperature sensor cable,
refer to section 10.6 for details of how to do this.
It is recommended that the upper mounting bracket
of the hydraulic station is positioned approx. 1600 to
1700mm above the floor level for ease of access and
operation of the controls, see Fig. 14.
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 hydraulic
station
Remove the front insulation moulding (Fig 15. Item 1)
by pulling forward whilst holding the solar differential
controller moulding (Fig 15. Item 2) in place. carefully
remove the solar differential controller mounting by
pulling forward and disconnect the pump cable connector
(Fig 15. Item 3). Place the hydraulic 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 15.
Item 4) and remove rear insulation moulding (Fig 15. Item
5). Drill and plug the mounting positions and screw the
mounting brackets into position. Push the rear insulation
moulding over the wall brackets and refit the hydraulic
assembly (Fig 15. Item 6) to the mounting clips on the
wall brackets.
