Water Connection; Water Drain Connection - Maytag MFR25PDCWS Installation Instructions Manual

9. WATER CONNECTION

The washer is equipped with 3/4" BSP (British Standard Pipe Thread) hot and cold water inlet valves,
indicated by a sticker next to the inlet. Use the water inlet hoses that accompany the washer as they are
properly adapted to the water valves. Water inlet hoses are BSP on one end and NPT (Nut marked with
groove) on the other end.
For best operation of the washer, water pressure must between 30 - 120PSI (pound per square inch) or 2 - 8
MPa. Water pressure that is below minimum requirements can lengthen the wash cycle or/and not allow
proper function of the washer.
To Install
Flush the water system in order to remove any particles that may be in the water system.
Insert the screen hose washer into the faucet connection end of the inlet hose and the standard hose
washer at the opposite end of the inlet hose.
When connecting inlet hoses, be sure hose connections are not cross-threaded on the water valves.
Tighten securely by hand plus 1/4 turn with pliers. DO NOT over tighten as this will strip threads on the
water valve(s).
The water hardness can have an influence on the wash results. The soap supplier can help you with making
the right decisions concerning hard water, soft water, washing programs, type of soap and other related
items to give the best wash results.
HOT WATER:
The hot water supply needs to be large enough to provide the required hot water for the installed washers.
For good wash results we advise a hot water supply that is set between 140 - 160°F / 60 - 70°C. To
determinate the boiler capacity you can use the data in below table. Please be aware that this is an average
and depends highly of the boiler temperature, linen, program set up and washing program used.

10. WATER DRAIN CONNECTION

The washer is equipped with a 75 mm / 3" O.D. drain valve which should be connected to the main drain pipe
or drain sump. The main drain pipe must have adequate capacity to handle the total output of all connected
washers and provide the necessary air release so that no back-pressure or/and drain slow down can be
generated.
Use the drain hose with elbow and clamp that accompany the washer as they are properly sized to connect to
the washer drain outlet. Secure the drain hose with the clamp.
The drain pipe or drain sump must be located lower than the machine drain pipes because the water
discharges from the machines by gravity. Do not reduce the diameter of the machine drain pipes.
Every time a machine is connected to the main drain pipe, the diameter of the pipe or the width of the waste
channel must be sized properly.
It is necessary to verify the main drain pipe or drain sump for proper function. If all washers are properly
connected to the drain, let all washers drain the rinse water simultaneously. All washers should drain empty
of water in approximately 30 sec or less.
