Earthing pipes
Arrange for work to be performed by a competent person.
One earthing clamp must be fitted to both the flow pipe and the return
pipe (at any position).
Connect the earthing clamps to the building's equipotential bonding
strip by means of a standard PVC-sheathed bonding cable (cable to be
sized in accordance with BS7671).
Insulating pipework
Thermally insulate the pipework in the entire solar circuit in
accordance with regulations and best practice.
Insulate outdoor piping with material which is both resistant to UV
light and high temperatures (up to 150 °C).
Insulate indoor piping with material which is resistant to high
temperatures (up to 150 °C).
Protect the insulation against damage from animals if required.

5 Installing the solar pump station
5.1 Layout of the installation space
To make it easier to connect the temperature sensors:
Install the solar pump station [2] as close as possible to the solar
cylinder [1].
Allow enough room for a solar expansion vessel [3] and holding
container [4].

[4] Drip pan
5.2 Mounting the solar pump station
Use a socket (13 mm) with a 150 mm extension to screw in the screws.
With shorter extensions, the handles and temperature gauges [3] can be
pulled forwards and removed for easier access to the screws.
Single-line solar pump station
Drill hole and fix solar pump station using rawl plug and screw
supplied [1, 2].
Twin-line solar pump station
Drill holes spaced 60 mm apart and fix solar pump station using rawl
plugs and screws supplied [4, 2].

Observe minimum clearances from the solar pump
station to the collector array of the vacuum tube
collectors ( Chapter 4.2, page 8)
DANGER: Danger to life through electric shock!
Before carrying out work on electrical components,
isolate them from the power supply (230 V AC) (fuse,
circuit breaker) and secure against unintentional
reconnection.
Electrical connections must only be completed by
appropriately qualified engineers subject to local and
national regulations.
NOTICE: Damage through pump running dry!
Do not run the pump until the pipework system has
been filled.
