Mounting Cased Pressure Supply Unit (PSU)
The cased PSU can be mounted using the mounting seat and strap provided.
When selecting a suitable mounting position, consider the following points:
●
The mounting seat should be secured to a level surface.
●
Ensure that both the high pressure output fitting and the on/off switch are accessible.
●
The motor on PSU is air cooled and has a fan to push air over the motor. The motor is rated to stay
under its max operating temperature in a max surrounding air temperature of 40C (104F). If the unit is
mounted in an enclosed space without adequate ventilation, the air in the space will heat to over 40C
(104F) very easily. If you are mounting the PSU in an enclosure with other machinery (e.g. in an engine
room), it is very important to ensure that the ambient temperature remains below 40C (104F) whilst
your watermaker is running at the same time as other machinery.
●
The PSU should be placed in the mounting assembly in the correct orientation. The embossed diagram
on the mounting seat shows the correct position.
Instructions
1.
Fasten the mounting seat using all four holes with the self-tapping screws provided or your choice of
alternate fastener.
2.
Slide the strap through the slot on the underside of the mounting seat.
3.
Place the PSU in the seat.
4.
If the pickup hose is coiled in the side pocket, pass the strap outside the pocket. If the pickup hose is
not in the side pocket, pass the strap through the pocket. The external pocket of the case can be
removed if desired to slightly reduce size.
5.
Tighten the strap.
