Water Connections - Equipment Marketers GA025L Installation Operation & Maintenance

Installation
IMPORTANT: Temperature of the water supply must
be kept between 40°F and 120°F (4.4°C and 48.9°C)
. If water in the supply line or water solenoid valve
freezes, the fire suppression system will not operate.
IMPORTANT: If temperature sensors inside the tumble
dryer register a temperature below 40F° (4.4°C) , the
fire suppression system control will lock out. This
feature protects against operation of the tumble dryer
with a possible frozen water supply. Only when the
temperature sensors register a temperature above
40F° (4.4°C) will the machine reset for operation.
IMPORTANT: Flexible supply line/coupling must be
used. Solenoid valve failure due to hard plumbing
connections will void the warranty. It is recommended
that a filter or strainer be installed in the water supply
line.

Water Connections

Two hoses and a Y-valve are provided with the tumble dryer to
allow for connection of water supply to tumble dryer. The water
connections are made to the bushings of the water solenoid
valve, located on the rear of the tumble dryer. The Y-valve
provides a single female hose connection (Standard US 3/4-11
1/2 NH thread). Refer to Figure 5 and Figure 6 .

To connect the two hoses (supplied with tumble dryer), insert
rubber washers (from literature pack) in water inlet hose
couplings. Refer to Figure 6 .

Connect inlet hoses to water supply. Flush the lines for
approximately two minutes to remove any foreign materials
that could clog the screens in the water mixing valve. This is
especially important when installing a tumble dryer in a newly
constructed or renovated building. Then connect the hoses to the
Y-valve; connect the Y-valve to the connections at the rear of
the tumble dryer.
IMPORTANT: Thread hose couplings onto valve
connections finger tight, then turn 1/4 turn with pliers.
Do not cross thread or overtighten couplings.
IMPORTANT: Hoses and other natural rubber parts
deteriorate after extended use. Hoses may develop
cracks, blisters or material wear from the temperature
and constant high pressure they are subjected to. All
hoses should be checked on a yearly basis for any
visible signs of deterioration. Any hose showing the
signs of deterioration listed above should be replaced
immediately. All hoses should be replaced every five
years.
NOTE: Longer inlet hoses are available (as optional
equipment at extra cost) if the hoses supplied with
the tumble dryer are not long enough for installation.
Order hoses as follows:
Part No. 20617 Inlet hose 8 feet (2.44 m)
Part No. 20618 Inlet hose 10 feet (3.05 m)
NOTE: Replacement outlet hoses are available (at
extra cost). Order 44073304 Hose, 14 in. (36 cm ).
