7 Installing the Dosing Pump
7.1 Set up information
When installing, follow the basic principles below:

The valves must be vertical: Discharge valve at top, suction valve at
bottom. in this connection, pay attention to the arrow on the dosing
head. The dosing head must be aligned such that the arrow points
vertically upwards.

You should install the dosing pump at a convenient height for opera-
tion.

It must not be installed under the ceiling.

The frame of foundation for fixing the dosing pump must not be
subjected to jolts. The pump must be vibration-free and stable.

There must be enough free space in the area of the dosing head and
the suction and discharge valves for these parts to be easily disman-
tled if required. The entire space requirement for installation and
maintenance is approximately 1 m².

The distance from the sides of the dosing pump to the wall or other
dosing pumps or equipment must be at least 3 cm. There must be a
guaranteed flow of circulating air.

The maximum ambient temperature must be complied with, see
“Operating conditions and limits” on page 12. If necessary, radiated
heat from surrounding equipment must be screened.

Avoid exposure to direct sunlight.

The dosing pump is not intended for use out of doors unless appro-
priate protective measures have been taken to prevent dust and
water from entering the housing.

For the dimensions of the fastening holes, refer to Chapter ”Dimen-
sions“ (see page 14).

The tightening torque for the fastening bolts is 1.5 - 2 Nm.
7.2 Installation examples
7.2.1 Installation on a wall console
Fig. 7-1: Installation on a wall console
To reduce the structure-borne noise, the dosing pump is bolted to the
wall bracket using rubber elements. The materials necessary for this are
included with the wall bracket.
7.2.2 Installation on the wall
Fig. 7-2: Installation on the wall
The dosing pump can be mounted to the floor or directly to the wall
without the need for additional elements. Turn the dosing head appro-
priately to ensure the flow direction of the medium through the dosing
head.
DANGER
Danger to life due to electric shock!
Electrically conductive liquid can enter pump housings, cable screw
connections and mains connectors.

Make sure that all protective measures comply at least with the
requirements of protection class IP65.

Always set up the dosing pump such that water cannot enter the
housing.
CAUTION
Danger of personal injury and material damage!
A dosing pump that is difficult to access represents a danger due to
incorrect operation and faulty maintenance.

Install the dosing pump such that it is accessible at all times.
