INSTALLATION
2.0 INSTALLATION
Village Marine Tec. recommends ALL Pure Water models (as with all other VMT model RO units) be INSTALLED
BELOW
the vessel’s waterline, to ensure a flooded suction i
ntake to the unit.
2.1a TO INSTALL THE PURE WATER UNIT
Village Marine Tec. recommends installing the RO unit in a dry sheltered location at or aft of midship,
with drainage underneath (to draw off standing water when performing routine maintenance or service).
Also, the RO unit should be installed
BELOW waterline (Refer to Figure 2.1). Give consideration to
extra space around the RO unit, allowing access for the unit’s maintenance (i.e. membrane
replacement, oil change, prefilter replacement, or other services).
Figure 2.1: Recommended Installation Location - BELOW waterline.
If the Pure Water
FRAME cannot mount below the water line then the boost pump must be mounted
separately below water line. This can be very convenient with modular or semi-modular formats where
the boost pump is already separate (see Figure 2.2).
Figure 2.2: Recommended Installation Location - ABOVE waterline.
The through-
hull should be ¾” for units up to PW1200 and 1” for PW 1600 and PW 2000. The through
-
hull must be attached with a ball valve (seacock).
