the solar circuit. It is mounted on a wall bracket and fixed with clips. The solar station is

optionally equipped with a controller. It contains importantfittings and safety devices for the

operation of the installation:

•Ball valves in the flow line (1.1) and return line (5.1)

•Check valves in the flow (1.1) and return ball valves (5.1)

•Thermometers in the flow (5.2) andreturn line (1.2)

•Pressure gauge to display the installation pressure (1.6)

•Flowmeter to display the flow rate (3.3)

•Ball valve to reduce the flow rate (3.1)

•Solar pressure relief valve (1.3)

•De-aerator to easily vent the solar circuit (4.2)

•Drain (3.2) andfill valves (1.4) with hose connectors

1.3 Designated use

The solar station may only be used as a pump station in the solar circuit taking into

consideration the technical limit values indicated in these instructions. Due to its design the

station must be mounted and operated as described in these instructions!

Improper usage excludes any liability claims.

When the sun shines, the collector can become very hot. The solar fluid

in the circuit can heat up to more than 100 °C.

Only flush and fill the solar circuit whenthe collector temperatures are

below 70 °C.

2 Safety instructions

The installation and commissioning as well as the connection of electrical components require

technical knowledge commensurate with a recognised vocational qualification as a fitter for

plumbing, heating and air conditioning technology, or a profession requiring a comparable level

of knowledge [installer]. The following must be observed during installation and commissioning:

•relevant local and national regulations

•accident prevention regulations of the professional association

•instructions and safety instructions mentioned in this manual

WARNING

Danger of scalding due to vapour escape!

With pressure relief valves there is risk of scalding due to vapour escape. During

installation, check the local conditions and if a discharge line must be connected

to the safety group.

Observe the instructions regarding the pressure relief valve.

The pressures calculated by the installation planner for the expansion

vessel and the operating pressure of the installation must be set.

CAUTION

Risk of burns!

The valves, fittings and the pump may heat up to more than 100 °C during

operation.

The shell must remain closed during operation.

•use appropriate personal and protective equipment eg safety glasses, gloves, etc...

0DNO0201 Installation-Operation ST1 Solar Pump Station 7

CAUTION

Personal injury and damage to property due to overpressure!

By closing the two ball valves in the primary circuit you isolate the pressure relief

valve from the heat exchanger. A rise in temperature in the storage tank will

cause high pressures and could result in personal injury or damage to property!

Only close the ball valves for service and maintenance.

NOTICE

Material damage due to mineral oils!

Mineral oil products cause lasting damage to seals made of EPDM, whereby the sealant

properties are lost. We do not assume liability nor provide warranty for damage to property

resulting from sealants damaged in this way.

It is imperative to avoid that EPDM gets in contact with substances containing mineral

oils.

Use a lubricant based on silicone or polyalkylene and free of mineral oils such as

Unisilikon L250L and Syntheso Glep 1 of the Klüber company or a silicone spray.
