Water Connection
Separate hot and cold plumbing lines (3/4 inch pipe or
larger) with individual shut-off valves must be
provided. Hot water should be a minimum of 160°F.
Best performance will be realized if water is provided
at a pressure of 30-85 psi. Although the machine will
function properly at a lower pressure, excessive fill
times will occur.
Use flexible hoses or equivalent flexible lines. The
hoses should hang in a large loop. Do not allow to
kink.
Flush the water system and check filters in machine
inlet hoses for proper fit and cleanliness before
connecting.
The UW50 has a total of four hose connections. Each
pair of hoses is connected to a hot and cold water
faucet with a 3/4 inch hose bib. Each machine requires
incoming water connections as follows:
Four 3/4 inch faucets with 3/4 inch hose bib
connected to two 3/4 inch hot water faucet lines and
two 3/4 inch cold water faucet lines.
Figure 9
Each of the hoses should have a screen filter installed
to keep rust and other foreign particles out of the
solenoid valves. These connections should be supplied
by a hot and a cold water line at least 3/4 inch size for
each. Installation of additional washers will require
proportionately larger water lines. Refer to Table 3.
Suitable air cushions should be installed in supply
lines to prevent “hammering.” If the water pressure is
above 60 psi, flexible copper tubing should be used in
place of the rubber hoses.
