Water Supply Requirements

Water supply requirements are as follows:

■ Valved hot and cold water supply with a water pressure

between 14.5 and 116 PSI (100–800 kPa). Water pressure between 43 and 73 PSI (300–500 kPa) is recommended.

■ A hot water heater or boiler supplying an adequate

amount of water between 120–160°F (49–80°C). The water temperature within the washer is controlled to a maximum temperature that is set in the program. The amount of hot water required to wash a load of laundry is dependent on many factors, including the hot and cold water temperature and the wash program selected. Average amounts of hot water required to wash one load of laundry are shown in the table below.

1. Main switch

2. Strain relief

3. Sag of inlet cable

Connection to Washer

These washers were designed for direct wiring into the power supply. The washer must be electrically grounded in accordance with all local codes or, in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70, latest edition, or Canadian Electrical Code, CSA C22.1.

Direct Wire Installation:

Power supply cable must match power supply (4-wire or 3-wire) and be:

■ Flexible armored cable or nonmetallic sheathed copper cable

(with grounding wire), in a exible metallic conduit, to avoid conductor breakage due to vibration. All current-carrying wires must be insulated.

■ Copper wire of appropriate gauge for amperage requirement

(see “Manufacturer’s Recommended Minimal Conductor Section”). Stranded wire is recommended. Do not use aluminum wire.

Equipotential bonding:

In addition to an equipment-grounding conductor that must be run with the circuit conductor and be connected to the equipment grounding terminal, all washers or appliances in the vicinity must be permanently interconnected with a connector.

The external connection points serve for this purpose. See illustration below.

The cross-sectional area of the conductor must be at least electrically equivalent to the cross-sectional area of the copper conductor.

■ Make sure all passages and spaces through which the

washer will be moved to its installation location are high enough and wide enough for the washer and its packaging.

■ Do not push, pull, or press the parts protruding from the

washer (front section, door, control panel, belt cover, water inlet, outlet pipes, etc.).

■ To avoid damage during handling and installation, make sure

all protruding parts are secured.

1. Move the washer near the point of installation with a lift truck and remove packing material.

2. Loosen the 4 - M16 x 160 mm bolts attaching the washer to

the pallet and gently lift washer.

IMPORTANT: Washer is very heavy. Consider equipment and manpower required to move this washer prior to installation and be sure that all necessary preparations are made.

Fastening Washer to Concrete Floor

1. Washer is to be attached to the concrete oor with anchor

bolts. All four footings must come into rm contact with the oor.

2. Level washer’s base frame with a level.

3. Do not tighten nuts of the anchor bolts until the concrete oor

or base has completely cured.

4. Tighten the nuts of the anchoring bolts to a maximum 155 lbf.ft/210 Nm for the bolts on Models MFS80, MFS100, and MFS125. For Models MFS180, MFS230, and MFS275 tighten the nuts of the anchoring bolts to a maximum of 36 lbf.ft/49 Nm.

Water, Drain, and Venting Connections

Water Hardness

Determine the water hardness level in water supply. Good wash results are dependent on water hardness. In areas that have medium and very hard water levels, a water softener may be required. Contact your water or soap distributor for determining the proper soap and detergents to be used with your hardness levels for the best wash results.

Water Supply Connections

Washers have 2 water inlets. For connection dimensions, see “Dimensions and Technical Specications.”

1. Always use the exible hoses delivered with the washer.

Do not use a xed connection to the water supply.

2. Keep proper water pressure within range. See “Dimensions

and Technical Specications.”

3. Connect all water inlets to a water supply. Contact your dealer

if there is no hot water supply available.

4. 1" (25 mm) or 1.5" (38 mm) Inlet valves for hot and cold water

use inlet pressure hoses with gaskets. Mount shut-off valves to the water supply pipes for cleaning lters and performing maintenance.

5. To connect the washer to the water inlet shut-off valves,

use the provided exible hoses.

Steam Connections

Washer with steam heating is equipped with an outer thread in the back of the washer for connection with the washer steam line. See “Dimensions and Technical Specications” for more details.

IMPORTANT:

■ Install a steam supply disconnecting device near each

washer.

■ Inlet value of steam pressure must be within range. Any

other pressure may result in washer not functioning properly.

■ To avoid possible injuries, shut off the main steam inlet and

let the parts cool down after connection.

■ Insert a lter with permeability up to 300 micrometers in

front of every steam valve. Dirt particles larger than 300 micrometers can damage the steam valve and cause leakage.

■ Attach steam lter to the washer at the connection point.

The supply piping must be clean without dirt and rust particles. Impurities in the supply line can cause steam valves to fail.

■ Do not twist the lter gasket when connecting the pipes.

To shut off the assembly, clamp the lter at the side of the connecting pipe.

Drain Connections

MFS80, MFS100, and MFS125 washers are equipped with two 3" (75 mm) diameter drain pipes. MFS180, MFS230, and MFS275 washers are equipped with two 4" (100 mm) diameter drain pipes. See “Dimensions and Technical Specications” for location. Both pipes must be connected to the waste sump. The sump must be positioned lower than the drain, because the washer uses gravity to discharge water. Use the provided drain hose to connect drain pipes to sump. Secure with a clamp and properly cover sump. The capacity of discharged water for each washer model is 300.00 dm3/min and 80.00 gal/min for the 3" drain. For the 4" drains, the capacity of discharged water for each washer model is 540.00 dm3/min and 142.00 gal/min.

Recycled Water Drain Connection (some models)

Attach connecting hoses to the discharging valve located on the right side (from rear view). The hoses go to your recycling tank located below the drainage valve. The tank must be large enough for the total weight and volume of water and made up of materials which withstand 176°F (80°C) and the effects of laundry soap. The quantity of water will vary by washer size and cycle.

Venting

IMPORTANT: To maintain proper venting, do not cover the

washer vent.

Although not recommended, it is possible to connect vent to the laundry central exhaust ducts. Venting materials must withstand a temperature of 176°F (80°C). Always use exible vent material if a connection is made. The central vent for multiple washers must be dimensioned for the total cross section of all vents and washers. Calibrate washer’s “zero” level after vent has been attached.

Electrical Connection

Check the data plate to determine electrical requirements. Before making the electrical connection, make sure the voltage and frequency listed on the data plate matches your electrical network. Each washer must be on an individual branch circuit. To ensure uninterrupted electrical current, a residual current device (RCD) and a circuit breaker must be installed in the building’s electrical system for each washer. The proper connection is described in the illustration on the right.

IMPORTANT:

■ If the washer is not equipped with a main switch, supply

disconnecting devices need to be installed in accordance with EN 60204-1 standard 5.3.

■ Make sure the supply voltage is always within the limits

specied in “Technical Specications.” If the electrical installation requires long distances to travel, it may be necessary to use larger cables to reduce the voltage drop.

Residual Current Device (RCD)

In some countries an RCD is known as an “earth leakage trip,” “Ground Fault Circuit Interrupter” (GFCI), “Appliance Leakage Current Interrupter” (ALCI), or “earth (ground) leakage current breaker.”

Specications:

■ Tripping current: 100mA (if locally not available/allowed use

a 30mA trip current, preferably selective type with small time delay set).

■ Install a maximum of two (2) washers on each RCD

(for 30mA, only one (1) washer)

■ Type B. There are components inside the washer which use

DC-voltages, making a “Type B” RCD necessary.

NOTE: Type B performs better than Type A, and Type A is

better than Type AC.

When locally allowed, an RCD must always be installed. In some electrical network earthing systems (IT, TN-C,…), an RCD might not be allowed (see also IEC 60364).

The washer control circuits are mostly supplied by a separating transformer. Therefore, the RCD may not detect faults in the control circuits (but the fuse(s) of the separating transformer will).

Supply Protection Device

A supply protection device keeps the washer and wiring from experiencing overloads and short circuits. As a supply protection device, you can use either glow-wire fuses or automatic circuit breakers. See “Technical Specications” for the rating of the nominal current and other specications of the supply protection device. This table species that protection must be the “slow” type, curve D for circuit breakers. Although not recommended, if you cannot use a “slow” type, select the protection device with one (1) step higher nominal current rating to avoid disconnecting during start-up.

Supply Cable

The supply cable is not delivered with the washer.

Specications:

■ Use conductors with copper cores.

■ Stranded conductors (exible wiring) are strongly

recommended to avoid conductor breaking due to vibration.

■ The cross section depends on the used supply protection

device. See “Manufacturer’s Recommended Minimal Conductor Section” in “Electrical Requirements” for the minimal cross section.

■ The cable should be as short as possible, directly across

from the supply protection device to the washer without branching off.

■ Do not use a plug or extension cords; the washer is intended

to be permanently connected to the electrical network.

Connection:

■ Insert the cable through the hole on the rear panel.

Use a strain relief to secure the supply cable.

■ Strip the conductor ends according to “Adaptation of

Conductor Ends of Supply Cable” illustration on the right.

■ The protective conductor must be longer to ensure it

is the last one disconnected if the cable is pulled out unintentionally.

■ With stranded conductors, it is recommended to use

“wire-end tubes” with an insulated sleeve (6) for L1/U, (L2/V), (L3/W), (N) conductors. Make sure there cannot be unintentional contact, since the supply cable stays under voltage even when the main switch is off.

■ Crimp a ring terminal (eyelet) to the protective conductor for

good connection to the PE terminal.

■ Connect the supply cable conductors to the terminals

(main switch [1]) marked with L1/U, (L2/V), (L3/W), (N), and the terminal (copper screw) marked with PE. See “Main Power Inlet Connection” illustration below.

■ Provide a sag in the cable, in front of the cable strain relief.

This will stop condensed water from entering the washer. See “Main Power Inlet Connection” illustration below.
