WARNING! When the acoustic pressure exceeds the value of 85 dB(A), it is necessary to
wear personal ear protection equipment.

4. INSTALLATION
Depending on the unit being used, the petrol engine pumps from MASTER PUMPS are mounted
on a solid base plate with vibration dampeners. These components must be in place during the
operation of the unit since they provide for a secure standing and reduce vibrations.
4.1. General installation information
During the entire installation process, the unit
must not be running.
All connection lines have to be perfectly tight since leaking lines may affect the performance of the
pump and cause considerable damage. Therefore, please use Teflon tape to seal the contact
surfaces between the threaded sections of the lines and the connection with the pump. This use of
sealing material such as Teflon tape is the only way to ensure an airtight assembly.
When tightening threaded connections, please do not apply excessive force which may cause
damage. When laying the connection pipes, you should make sure that the pump is not exposed
to any form of weight, vibration or tension.
4.2. Installation of the intake line
The inlet of the intake line is to be equipped
with a filter for keeping away larger dirt particles
contained in the water which might clog or even
damage the pump.
The liquid to be discharged enters the pump through the suction line. Please use a suction line
having the same diameter as that of the suction port of the pump. If the suction height exceeds 4
m, however, it is recommendable to use a 25% larger diameter - including appropriate reducer
elements for the connectors.
The inlet of the intake line is to be equipped with a filter for keeping away larger dirt particles
contained in the water which might clog or even damage the pump.
Moreover, it is highly recommended to install a check valve (non - return valve) which prevents the
pressure from escaping after the pump has cut out and thus protects the pump from damage
caused by pressure surges. This check valve may be installed either directly at the suction port of
the pump or at the inlet of the intake line. The installation at the inlet of the intake line has proven
to be beneficial since it facilitates the venting of this intake line by enabling it to be filled with water.
