Page: 23 / 78

1.
Read the instructions through before installing the pump and starting it up. If
in doubt, contact your local APV dealer.
2.
Check that the specifications of the motor and motor control unit are correct,
particularly in operating environments where there may be a risk of
explosion.
3.
Do not start the pump before all the pipe connections have been fitted care-
fully and tightened. If the pump is to be used for hot and/or hazardous liquids,
special precautions must be taken. In such cases follow the local regulations
for personal safety when working with these products.
4.
Do not start the pump before the motor shroud or shaft guard has been
securely fitted.
5.
The pump contains rotating parts. Never put your hands or fingers into a
pump while it is in operation.
6.
Never touch the shroud during operation, as it can become very hot.
7.
Never touch the pump body during operation if the pump is being used for
hot media where there is a risk of burning.
8.
Never close both the intake and outlet of the pump while it is in opera-tion. If
the pump runs with liquid in it without circulation, the liquid will heat up and
may turn into vapour, causing a risk of explosion.
9.
Always remove all assembly tools from the pump before starting it up.
10.
Never hose down the electric motor directly with water or cleaning fluid.
11.
Never lift the pump in the shroud, as it is not designed to carry the weight of
the motor. Remove the shroud before lifting the pump. Always use securely
fitted lifting straps when lifting with a crane or similar lifting gear.
12.
Never dismantle the pump before the motor has been disconnected from the
power supply. Remove the fuses and disconnect the cable from the motor
terminal box.
13.
All electrical installation must be carried out by qualified staff.
14.
Never dismantle the pump until the pipe system has been drained.
Remember that liquid will always collect in the pump body. If the pump is to
be used for hot and/or hazardous liquids, special precautions must be taken.
In such cases follow the local regulations for personal safety when working
with these products.
