4.2  Components installation 

4.2.1 

Pump group 

The pump group must be installed as close as possible to the waterline as (maximum no more than 600mm 
above) and as close as possible to the water inlet (2m max). Therefore, it is very important to avoid starting 
the system if the intake valve is closed or if inlet filters are clogged. 
The pump group should be installed in a ventilated area, with the purpose of aiding the cooling of the motor. 

The max allowed room temperature must not exceed 40°C

.   

Avoid  the  contact  or  the  proximity  with  inflammable  material  or  liquid,  since  the  motor  surfaces  can  reach 
elevated temperatures. Avoid locating the pump wherever a possible loss of water can involve damages or 
jeopardize its safety. The pump group must be installed on a base sufficiently horizontal, suitable to sustain 
the weight of the group. The pump group is normally fixed on the support structure by passing bolts.  
 

4.2.2 

Watermaker group  

Install  the  watermaker  above  the  pump. 

The  max  allowed  room  temperature  where  the  watermaker  is 

installed must not exceed 40°C

. It can be placed either horizontally or vertically. 

The watermaker must lie 

completely on a flat surface. The supplied neoprene-based adhesive must absolutely be stuck to the 
supporting surface, cutting it in such a way to cover as much as possible of the surface.

 Once in place 

on the supporting surface, the watermaker must be fastened with the provided L-brackets and the rubber nubs. 

In no way must the watermaker be suspended using solely the L-brackets but it must  rest on a flat 
surface at all times. Otherwise a shelf is necessary as base to support the weight of the watermaker. 

The brackets are colour-coded according to their position.
