Check the fittings and seals. Inspect the threaded fitting on each hose and make sure there is a rubber seal a in place in both ends of each hose to prevent leaking.

Check the type of installation and connect the hose to the faucet. Connect all water supply hoses tightly by hand and then tighten another 2/3 turn with pliers.
Type 1 : WITHOUT WASHER (The dryer does not share the faucet with the washing machine.)
Connect the straight end of the long hose b to the cold water faucet.

Type 2 : WITH WASHER (The dryer shares the faucet with the washing machine.)
Shut off the cold water tap and remove the washer inlet hose.
Connect the short hose c to the Y-connector d using one of the rubber seals.
Connect the other end of the short hose c to the cold water faucet.
Connect the long dryer hose b to one side of the Y-connector d. Connect the washer hose to the washer and the other side of the Y-connector d.

Before connecting the water line to the dryer, flush out the hose with several gallons of water into a drain or bucket. This will help prevent foreign particles such as sand and scale from clogging the dryer inlet valve.
Connect the long dryer hose b to the dryer inlet valve tightly by hand and then tighten another 2/3 turn with pliers.

Turn on the cold water faucet.

Check all hoses and Y-connectors (if used) for leaks.

If any leaks are found, shut off the water faucet, remove the hose and check the condition of the rubber seal.
