Specifications

Open the small spigot valve on the bottom of the flow
gauge. Sample the water by tasting or using a hand held
salinity probe.
If water is acceptable, close the spigot valve and rotate
primary control panel valve from normal to manual tank
fill.
Operating in this manner reduces the system to its
simplest form and assures water production without
necessitating complex electronic components.
Caution: The manual override valve is a high quality
laboratory grade valve, designed not to allow fluids to
combine. There is, therefore, a small spot on its travel which we determine a spot X that
does not allow the product water to flow into the tank or the automatic selection valve on
the panel. It is possible to use this spot X to force all system product water through the
spigot valve at the bottom of the flow meter. This is used for filling up a bucket when the
system is to be preserved or to transfer RO watermaker through a hose to a friend's vessel
or for other special applications. It should be noted that if this main control valve is in
position X and the spigot valve on the flow meter is in the closed position, that the high
pressure will build to a point where the product water hose running from the RO membrane
to the control panel may be ruptured.
Filter Pack
The filter pack is provided with transfer relays to provide electrical current for the feed
water pump at the filter location, as well as a toggle switch to operate the feed water pump
during filter cleaning or replacement. This allows the operator to activate the feed water
pump while depressing the air release buttons on the top of each filter of the filter pack.
This switch is left normally in the DOWN and OFF position.
