11. Remove the four bolts (8) and remove the outlet flange (7) and ’O’ ring seal from the pump
body.
12. Turn the outlet flange through 90
o
(so that it is orientated as shown in Figure 2, item 4),
ensure that the ’O’ ring seal is correctly located, then refit the outlet flange to the pump and
secure with the four bolts (8).
3.5 Locate the pump
CAUTION
Locate the pump so that it is on a firm, level surface. If you do not, seals in the pump may
wear quickly and the performance of the pump will deteriorate.
Ensure that the pump is not installed in an enclosed area. The pump requires a cooling-air flow
rate of 5 m
3
min
-1
. The cooling-fans will provide this flow rate if the pump is not installed in a
restricted space.
Refer to Figure 1. Attach suitable lifting-gear to the lifting-eye (4) on the pump and move the
pump to its final operating position. The pump can be free-standing or you can use fixing-bolts
through the mounting-holes (14) in the base-plate of the pump to secure the pump to the floor.
If you want, you can fit vibration isolators below the base-plate. Suitable vibration isolators are
available as optional accessories (see Section 7).
3.6 Connect the electrical supply
CAUTION
The motor is not thermally protected. You must provide external overload protection.
Branch circuit fuses must have a maximum rating of 115% of the full load current rating
given in Section 2.
3.6.1 Introduction
Connect the electrical supply to the motor as described in Section 3.6.2 or 3.6.3. Connect the
supply through a contactor which incorporates a circuit breaker suitable for the full load current
ratings given in Section 2.
