3. Installation
The pumps are OEM models intended for installation in equipment.
When installing them make certain that accident prevention
regulations, and safety instructions, including those for subsequent
operation are observed. The safety instructions in section 2 must
be observed.
The dimensions of the mountings are given in the Data Sheet.
Install the pump so that the fan can draw in sufficient cooling air.
Install the pump so as accidental finger contact is with the fan is
impossible.
Fit the pump at the highest point in the system, so that condensate
cannot collect in the head of the pump - that prolongs working life.
When making the electrical installation the safety regulations
must be observed. In particular make sure that the electricity
supply is isolated before trying to connect the pump.
Compare the supply data with the data on the motor-plate. The
voltage must not vary by more than +6% and -10% from that
shown on the type-plate.
The earth (ground) wire must be connected to the motor.
In the electrical installation, arrangements (complying with EN
60335-1) must be made for disconnecting the pump motor from the
electrical supply.
The pump must be installed so that contact with live parts (e.g.
electrical connection) is impossible.
We recommend that a fuse is installed in the supply circuit; the
operating current is given in Data Sheet.
Remove the protection plugs from the port threads.
Connect the suction and pressure lines (for size of the port threads
see section 10). For flow direction see marking on the pump head
or data sheet.
Arrange the suction and pressure lines so that condensate cannot
run into the pump (sloping lines).
