Position the pump
Use suitable lifting equipment attached to the lifting eyebolt to move the
pump to its nal operating position. Refer to
When positioning the pump make sure that access to the pump electrical
supply cable or any other controls are not obstructed.
Make sure that there is a minimum air gap of 40mm on all sides of the
pump to allow effective air circulation.
The pump must be located on a rm, level surface capable of supporting the
mass of the pump.
The system should be installed away from combustible materials.
The pump can be secured to the oor by using the four holes located on
each corner of the pump base. We recommend using M6 (Class 12.9) bolts
of suitable length (not supplied).
The pump must be in level to a maximum of 3° in any direction, measured at
the pump inlet.
It is your responsibility to carry out a risk assessment of their location and
take appropriate measures to make sure that the dry pumping system
is manoeuvred safely and in accordance with local and national manual
handling guidelines.
6.5Connect to the vacuum system
WARNING: HAZARDOUS SUBSTANCES
Risk of injury. If pumping dangerous gases or vapours, connect the exhaust to a
suitable treatment plant to prevent the discharge of dangerous gases and vapours
to the surrounding atmosphere.
CAUTION: OVERPRESSURE
Risk of damage to the equipment. If the pump is operated with the exhaust line
blocked, high pressure may be generated in the exhaust line pipework.
Before connecting the pump to the vacuum system, remove the plastic cap
from the inlet and exhaust, and make sure that the inlet strainer is tted
to the pump inlet port. Use appropriate DN 25 ISO-KF vacuum ttings for
connection to the system.
Take note of the following information when connecting the pump to the
vacuum system.
▪ To minimise noise and exhaust emissions, it is recommended that the▪
pump is connected to an exhaust line or a silencer.
▪ For optimum pumping speeds, make sure that the pipeline connected▪
to the pump inlet is as short as possible and has a suitable internal
diameter.
▪ Support the vacuum pipeline to prevent loading of the coupling joints.▪
▪ A pressure of 3bar(g) may be generated in the exhaust pipework if▪
the pump is operated with the exhaust line blocked. Connect the pump
using appropriate pipework and ttings.
