DC Genset / Watermaker Manual - Balmar

Open the small spigot valve on the bottom of the flowgauge. Sample the water by tasting or using a hand heldsalinity probe.If water is acceptable, close the spigot valve and rotateprimary control panel valve from normal to manual tankfill.Operating in this manner reduces the system to itssimplest form and assures water production withoutnecessitating complex electronic components.Auto/ManualSwitchCaution: The manual override valve is a high qualityAuto/manual switch / purge buttonlaboratory grade valve, designed not to allow fluids tocombine. There is, therefore, a small spot on its travel which we determine a spot X thatdoes not allow the product water to flow into the tank or the automatic selection valve onthe panel. It is possible to use this spot X to force all system product water through thespigot valve at the bottom of the flow meter. This is used for filling up a bucket when thesystem is to be preserved or to transfer RO watermaker through a hose to a friend's vesselor for other special applications. It should be noted that if this main control valve is inposition X and the spigot valve on the flow meter is in the closed position, that the highpressure will build to a point where the product water hose running from the RO membraneto the control panel may be ruptured.Filter PackThe filter pack is provided with transfer relays to provide electrical current for the feedwater pump at the filter location, as well as a toggle switch to operate the feed water pumpduring filter cleaning or replacement. This allows the operator to activate the feed waterpump 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.Final ThoughtsWe appreciate your purchase of the APC-750 DC Genset and RO Watermaker, and we lookforward to supporting you throughout its use on your vessel.
