3.1 Approved applications and operational
limits for the pumps
The pump and the pump units are designed for
the use in systems with tap water .
The PAH pumps must not be used for other
purposes than those recommended and
specified without first consulting your local
pump distributor .
Use of the pump in other applications not
suitable for the pump unit can cause damages
to the pump unit, with risk of personal injury .
For system integration of the pumps, please

same Data sheet .
3.5 Dimension drawings
Dimensions of the different pumps can be found
in appendix 1, Data sheet .
3.6 Space requirement
When doing service or replacing the complete
pump unit, it is recommended to have sufficient
space available around the pump in order to
ensure easy access . Sufficient space means at
least 1 meter/40 inches around the pump . When
working with high pressures, it is important to
have the right space available around the pump
as stated in the safety requirements .
It is always the system builders´ responsibility
that the system design does not cause any kind
of hazard and is adapted to local regulations and
standards .
Proper installation, proper start up and shut-
down devices as well as high-pressure protection
equipment is essential .
2.3 Commissioning and servicing the unit
It is recommended that commissioning and
servicing are carried out by a minimum of two
people, where one is acting as a supervisor .
2.4 Adhere to the following important
points
•
Before using the pump/pump unit it is very
important to read and understand this user
manual .
•
Do not try to lift the pump unit manually;
most of the pumps weigh more than
20 kilos, see specific weight for the pump
in the appendix 1, Data sheet .
•
Always bleed the pump prior to initial
start-up .
•
Do not mount the pump without the bell
housing and a flexible coupling .
•
Do not try to start the unit before the
system components are mounted, bleeded
and adjusted .
•
Flush the system throughly before
connecting the pump or pump unit .
•
Check rotation direction of the motor
before mounting the pump .
