7 Installing the Dosing Pump
DANGER
Mortal danger from electric shock!
Electrically conductive liquid can enter pump housings, cable screw
connections and mains connectors.
ð
Make sure that all protective measures comply at least with the re-
quirements of protection class IP65.
ð
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.
ð
Install the dosing pump such that it is accessible at all times.
7.1 Set up information
When installing, follow the basic principles below:
n
The valves must be vertical: Pressure 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.
n
You should install the dosing pump at a convenient height for opera-
tion.
n
It must not be installed under the ceiling.
n
The frame of foundation for fixing the dosing pump must not be sub-
jected to jolts. The pump must be vibration-free and stable.
n
There must be enough free space in the area of the dosing head and
the suction and pressure valves for these parts to be easily disman-
tled if required. The entire space requirement for installation and
maintenance is approximately 1 m².
n
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.
n
The maximum ambient temperature must be complied with, see
chapter 5.2 “Operating conditions and limits” on page 13. If neces-
sary, radiant heat from surrounding equipment must be screened.
n
Avoid exposure to direct sunlight.
n
The dosing pump is not intended for use out of doors unless appropri-
ate protective measures have been taken to prevent dust and water
from entering the housing.
n
For the dimensions of the fastening holes, refer to chapter 6 “Dimen-
sions” on page 19.
n
The tightening torque for the fastening bolts is 1.5 – 2 Nm.

To reduce the structure-borne noise, the dosing pump is bolted to the wall
bracket using rubber elements. The materials necessary for this are in-
cluded with the wall bracket.
