Connecting the Purified Water Supply
To prevent valve and pump clogging, flush all of the water lines for your purified
water supply source prior to connecting the washer to the water lines. The valve
to which the purified water supply must be connected is located on the back of the
washer base. The back panel of Freestanding models must be removed to access
the valve. Refer to the previous figure.
The purified water inlet valve is equipped with a plastic hose barb connection to
accommodate .375" (9.53 mm) ID flexible plastic or rubber hose. The hose
connection may be removed from the valve to expose a male 3/4" – 11-1/2 NH
hose coupling. Rigid plastic, tin-lined, or stainless steel tubing and fittings may
be connected to the washer fitting.
At least 0.9 gallon (3.4 liters) per minute of purified water flow is required. At
least 3.4 gallons (12.9 liters) of purified water must be available for each pure
rinse. A .375" (9.5 mm) ID pipe is the minimum recommended.
If you do not use purified water during the rinse cycles, you may disable the
purified water pump. Refer to Controller Set-Up in this section.
If the washer has been converted to a Mobile model and is moved to various
locations, and if purified water is used, provisions must be made to use a flexible
hose from a source of house-purified water. If a carboy is used, place the carboy
on a carboy cart and move it with the washer. Be careful not to let the hose kink
or become damaged.
To connect the purified water supply:
1.
Make certain the purified water supply piping has been thoroughly flushed
prior to connecting it to the washer.
2.
Make the necessary plumbing connections to properly connect the purified
water supply to the washer.
NOTE: If the purified water source is a carboy, complete steps 3 and 4.
3.
Connect the purified water source through either the top or the bottom of the
carboy, as illustrated in the following figures. If the purified water supply
feeds directly from the carboy top, make certain the hose is submerged under
the water line. Attach a weight to the end of the tubing to keep it from
floating on top of the water and possibly allowing air into the system.
4.
Make certain the top of the carboy is vented to permit proper flow from the
carboy to the washer. Make certain that all of the connections on the purified
water system are air tight. The pump must not pull air instead of water. Make
certain the supply hose is not crimped.
