position to facilitate inspection or replacement.
- For heavy pumps, install a lifting hook (Fig. 2,
item 10) above the pump in order to ease its dis-
assembly.
- The motor is provided with condensate hole
(under the motor), filled in factory by caps to
guarantee the IP55 protection. For a use in tech-
nical climatological or refrigerated, these caps
must be removed to allow the evacuation of the
water of condensation.
WARNING! Risk of accident by hot surfaces!
The pump must be positioned so that someone
cannot come into contact with the hot pump sur-
faces while operation.
