Water Supply Requirements; Connecting Hoses - JLA 98 Installation & Operation Manual

Installation

Water Supply Requirements

Water supply faucets must fit standard 3/4 inch [19 mm] female
garden hose couplings. DO NOT USE SLIP-ON OR CLAMP-
ON CONNECTIONS.
NOTE: Water supply faucets should be readily accessi-
ble to permit turning them off when washer is not being
used.
Recommended cold water temperature is 50° to 75° Fahrenheit
[10° to 24° Celsius]. Recommended maximum hot water temper-
ature is 125° Fahrenheit [51° Celsius]. Warm water is a mixture
of hot and cold water. Warm water temperature is dependent upon
the water temperature and the pressure of both the hot and cold
water supply lines.
To prevent personal injury, avoid contact with inlet
water temperatures higher than 125° Fahrenheit [51°
Celsius] and hot surfaces.
Maximum flow rate for all water temperatures is 2.5 gallons per
minute [9.46 liters per minute] ± 15%.
Water pressure must be a minimum of 1.4 bar to a maximum of
8.3 bar [minimum of 138 to a maximum of 827 kPa] static pres-
sure measured at the faucet.
NOTE: Water pressure under 20 pounds per square
inch [138 kPa] will cause an extended fill time in the
washer and may not properly flush out the detergent
dispenser.
The appliance is to be connected to the water mains using new
hose-sets and the old hose-sets should not be reused.
Turn on the water supply faucets and flush the lines for approxi-
mately two minutes to remove any foreign materials that could
clog the screens in the water mixing valve. This is especially im-
portant when installing your washer in a newly constructed or
renovated building. Build-up may have occurred during construc-
tion.

Connecting Hoses

Model Numbers Ending in "06" (through Serial No.
1909999999): To comply with water regulations, this washing
machine must be fitted with an approved 3/4 inch double check
valve to both the hot and cold supplies between shut off valve
and fill hose. Refer to Figure 7 . Maximum water flow rate to the
dispenser is 10 liters per minute. Installation Notice: Note that the
Machines must be installed with Double Check Valves at the Fau-
cets which are not supplied.
1. Insert rubber washers and filter screens (from accessories
bag) in water fill hose couplings (two hoses supplied with
washer). The filter screen must be facing outward.

WARNING
Models Through Serial Nos. Beginning 1810:
NOTE:
If using black rubber hoses with black and brass cou-
plings: Insert filter screens into the BLACK colored
hose couplings (BSPP thread). Insert rubber washers
into the brass colored hose couplings (Garden Hose
Thread [GHT]).
If using gray braided hoses with silver hose couplings
(one with hex nut): Insert filter screens into the hex nut
shaped hose couplings (BSPP thread). Insert rubber
washers into the knurled, round shaped hose cou-
plings (GHT).
Models Starting Serial Nos. Beginning 1810:
NOTE: Water mixing valve connections at rear of
washer are BSPP thread. Both hose couplings on fill
hoses included with machine are also BSPP thread.
2. Connect fill hose couplings with filter screens to water supply
faucets.
3. Connect the other hose couplings to the hot and cold valve
connections at the rear of the washer.

Models Through Serial Nos. Beginning 1810:
NOTE:
If using black rubber hoses with black and brass cou-
plings: Connect the BLACK colored hose coupling
(BSPP thread) end of the fill hoses (with filter screens)
to the water supply faucets. Then connect end of hoses
with the brass colored hose couplings (GHT) to the hot
and cold water mixing valve connections at rear of
washer.
If using gray braided hoses with silver hose couplings
(one with hex nut): Connect the hex nut shaped hose
couplings (BSPP thread, with filter screens) to the wa-
ter supply faucets. Then connect couplings with
knurled, round shaped couplings (GHT) to the hot and
cold water mixing valve connections at rear of washer.
Models Starting Serial Nos. Beginning 1810:
NOTE: Water mixing valve connections at rear of
washer are BSPP thread. Both hose couplings on fill
hoses included with machine are also BSPP thread.
4. Make sure the hose from the hot water faucet goes to the wa-
ter mixing valve marked "H" and the hose from the cold fau-
cet goes to the valve marked "C".
5. Thread hose couplings onto valve connections finger tight.
Then turn 1/4 turn with pliers.
IMPORTANT: DO NOT cross thread or overtighten
couplings. This will cause them to leak.
6. Turn water on and check for leaks.
7. If leaks are found, retighten the hose couplings.
8. Continue tightening and rechecking until no leaks are found.
