1.0 SYSTEM DESCRIPTION
The Village Marine Tec. (VMT) Seawater Desalinator is a single-pass purification
system that uses reverse osmosis (RO) as its method of seawater desalination. This
unit produces potable (drinking) quality water with salt concentrations of < 500 ppm by
removing approximately 99% of the dissolved salt in seawater.
This manual covers the following models: PW3000, PW4000, PW5000, PW6000,
PW7000, PW8000, PW10000, PW12000, PW16000 and PW20000. The principle of
operation is the same for all models. Specific differences are noted, where applicable.

(2) Raw water temperatures less than 25°C (77ºF) will result in less than rated
product water output. Conversely, higher raw water temperatures will result in
higher than rated output.
