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.

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].

Observe minimum clearances from the solar pump
station to the collector array of the vacuum tube
collectors ( Chapter 4.2, page 8)

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].

Electrical connection
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.
