Installation
Machine foundation
The machines are designed to be bolted in
position to a concrete floor or specially prepared
concrete foundation. A template showing the size
of the foundation and positioning of the
foundation bolts is delivered with each machine.
For installation on an existing concrete floor, the
floor must be at least 8" thick and of good quality.
If the floor does not meet these requirements,
then a 6-8" high concrete foundation should be
made. A prefabricated steel base is available for
mounting of machines without an additional
foundation.
Follow the instructions below when making a
concrete foundation:
1. Decide where to place the machine and
consider maintenance requirements, i.e.
determine a suitable distance from the rear of
the foundation to the wall, and the distance
from the foundation to the nearest side wall.
The distance should be at least 16 and 12
inches, respectively.
2. Break up the floor to a depth of 3 inches,
making sure that the sides of the hole slope
inwards - the bottom of the hole should be 5
inches longer than the upper length.
3. Wet the hole well. Brush the bottom and sides
with cement grout.
4. Prepare a casing and fill with concrete to form
foundation. Make sure the foundation is level.
5.
Use the template to position the foundation
bolts correctly - bolts are to extend 1 1/2"
above concrete.
NOTE: A prefabricated steel frame, designed
to be placed in the concrete instead of the
individual mounting bolts, is available.

Mechanical installation
• Place wide steel shims on the concrete foundation over the bolts.
• Lift the machine and lower it in position. Never
use the door or the door handle to lift or lower
the machine.
• Check that the machine is level front-to-rear
and side-to-side and standing firmly on the
four (W75, W105) or six (W125 W185) supporting points. Spacing washers must be
mounted if one or more of these points is not
resting against the floor/foundation.
• Place flat washers over the foundation bolts
and secure the machine in position by tightening the self-locking nuts. See illustration
below.
• Check and tighten the nuts every week for the
first month.

Installation
Electrical installation
Although the machines are fitted with a thermal
overload in the motor windings a separate threephase common-trip circuit breaker must be
installed for all three-phase machines.
For proper overcurrent protection, check the data
plate at the rear of the machine. Also consult
local electrical code for special requirements.
Connect L1, L2, L3 and ground wires according
to the markings of the terminal block. The cable
is to hang in a large loose loop, supported by the
clip of the terminal block.
After installation, do the following for 3-phase
machines:
Check the incoming power for a high voltage leg.
If present, connect that line to L2 on the terminal
block.
Start the machine and check that the drum
rotates in the proper direction during extraction,
i.e. counter-clockwise when seen from the front.
If the drum rotates in the wrong direction intercharge line L1 and L3 at the power connection
terminal.

Water connection
NOTE
All plumbing must conform to national
and local plumbing codes.
Incoming water lines do not require non-return or
back-suction valves, as the machine is already
fitted with a siphon breaker. However, all incoming lines must be fitted with shut-off valves.
• Water inlets are labelled for hot and cold
water connection.
• Flush the water system thoroughly and check
that the filter at the machine inlet is fitted
correctly.
• Connect the machine to the water mains with
3/4" reinforced rubber hosing not to exceed 6
ft in length. Hang the hosing in a large loop.
Do not use rigid piping.

How to size water supply piping for Wascomat coin laundries
1. Calculate the total number of gallons of water that would be needed if all present (and
future) washers were to fill at the same time. Assume the W75 (18-lb.) uses 7 gallons
per fill; W105 (25-lb.) uses 10 gallons per fill; W125 (35-lb.) uses 14 gallons per fill‚
W185 (80-lb.) uses 20 gallons per fill; and W244 (75-lb.) uses 30 gallons per fill. If
water pipe runs of 70 feet or longer are required, multiply by 1.25 to compensate for
pipe friction which reduces flow rates.
2. Using the Flow Chart below and knowing the water pressure in the water main at your
store, select a pipe diameter that has a gallons per minute (gpm) flow rate the same or
higher than the total calculated above. The hot water line and the cold water line
supplying the washers must
each be this size diameter, since many fills are all hot or
all cold. This will assure fill times of approximately 1 minute and normal cycle times.
Wascomat washers are designed to operate at 25–85 PSI Call your local water utility
company if you do not know the water pressure in your water main.

3. The water line from the laundry to the water main in the street must carry
double the
total gallons capacity calculated in paragraph 1. Select the correct diameter from the
Flow Chart. (You will note from the chart that two 2'' pipes do
not equal the flow rate of
a 4 inch pipe; two 1'' pipes do
not equal the flow rate of a 2 inch pipe, etc... Use the
correct gpm flow rates!)

Drain connection
Connect a 3" (75 mm) flexible hose to the drain
outlet of the machine.
The drain hose must not have sharp bends and
must slope from the machine to assure proper
drainage. The outlet must open freely to the main
drains.
Do not reduce the size of the drain connection
from the machine to the waste line.
Start-up and safety checklist
Before initial start-up of a Wascomat washerextractor, the following safety checks must be
performed:
• Make sure the machine is properly bolted to
the floor.
• Make sure that all electrical and plumbing
connections have been made in accordance
with applicable local codes.
• Use only flexible water fill and drain hoses of
the proper length to avoid sags and kinks.
• Make sure the machine is properly grounded
electrically.

interlock must be checked for proper operation
as follows:
• When washer loading door is open, the machine must not start. Verify this by attempting
to start washer with door open (see section
”Procedure”).
• When washer is in operation, the loading door
is locked and cannot be opened. Verify this by
attempting to open the loading door when the
machine is operating. If necessary, consult
this manual for proper operation of the door
lock and door safety interlock or call a qualified serviceman.
IMPORTANT:

Door, description
The door consists of a backing frame (1), door
(2), glass (3) and door gasket (4). The backing
frame and door are both made of enameled
aluminium. The backing frame is bolted directly
to the outer shell of the washing machine.The
door hinges are fastened on the outside of the
backing frame and the door lock (5) on the inside. The heat-hardened glass is mounted in the
door using a special rubber seal which also acts
as a gasket between the door and the washing
machine’s outer shell when the door is closed.
Door lock, description
The door lock consists of a circuit board (1) with
a connector. Mounted on the board are the lock
plate (2), against which the locking bolt turns to
lock the door, and a microswitch (3) which closes
when the locking bolt has locked the door.
There is also a locking device on the circuit board
which acts to lock the locking bolt in place when
the machine starts up.
The locking device consists of a double-acting
solenoid (4), a delay unit (5) and the locking
device itself (6) which operates sideways in
blocking the locking bolt with a stud. The locking
device can be affected by both the solenoid and
the delay unit.
The lock operates as follows:
• When the door is shut and the locking bolt
moved to the lock position, the micro switch
will indicate that the door is closed.
• When the machine is started, the solenoid
actuates the locking device, blocking the door
lock. The locking device signals the delay
unit, closing a switch in the unit. The washing
machine motor will start and water enter the
machine only after the delay unit receives the
information that the door is locked. The bimetallic spring in the delay unit is warmed up
at the beginning of the program.
• Once the washing machine stops at the end of
a cycle, the solenoid pulls back the locking
stud and allows the door to open. The delay
unit is spring-mounted in the locking device
and is also pulled back by the solenoid. The
solenoid operates for about two minutes to
allow the bi-metallic spring to cool enough not
to lock the door again.
• If current should disappear during a cycle, the
delay unit will keep the door locked for about
two minutes, ensuring that the wash water can
drain out (The drain valve opens automatically
when current is lost).

Relays
The Wascomat W models employ two relays.
The relays control:
• the wash speed (1)
• the extract speed (2)
Construction
The body of the relay holding the stationary
contacts is made of current-resistant plastic. A
solenoid and a contact bank hold the moving
contacts. The contacts are spring-loaded to
assure the correct contact pressure.
The relay is constructed for continous operation,
whether mounted horizontally or vertically.
Screw-type terminals provide perfect connections
even when one or two wires have different diameters.
Operation
When the solenoid is energized, the two halves
of the magnet core are drawn together, pulling
down the moving contacts, thus making or
breaking the circuit. When the current cuts out,
springs force the contact bank into its original
position, thus closing or opening the circuits.
Trouble shooting
If the relay fails to operate despite power to the
coil, turn off the power and check the solenoid by
measuring the resistance across the terminals
(1).
If the relay hums when power is applied, this
indicates either a break in the insulator holding
the moving contacts at the axle where it holds the
top half of core (3), or a rusty core (4), which can
be cleaned.
Make sure that the moving contact assembly
moves freely. Always replace burnt or pitted
contacts (2) ... do not reuse contacts.

Drive motor
Description in general
The motor is mounted on an axle with rubber
dampeners.
The V-belt is tightened by turning the motor on
the axle and locking it in place using the
tensioner on the rear side of the motor. The
motor and tensioner have vibration and noise
dampening rubber suspensions.
Construction in general
The motor consists of stator, rotor and endshields with ball-bearings. The stator and the
rotor consist of plates, insulated from each other
and welded together. The stator is provided with
slots in which the 2-pole and 18-pole windings
are wound. The windings are impregnated with a
temperature-resistant sound-insulating resin
varnish according to class B. The end-shields are
die-cast. The ball bearings are permanently
lubricated.
Construction of single-phase motor
Single-phase motors have an 18-pole winding
(wash-speed) the same as three-phase motors,
using a continuously connected capacitor, while
the 2-pole winding (extract-speed) is a specially
designed winding with both a continuously
connected capacitor and a starting capacitor.
Function of 3-phase motor
When the stator winding is charged, a magnetic
field will occur, which in turn will rotate the rotor
at a fixed RPM depending upon the number of
poles in the winding. The 18-pole winding gives
the wash speed and the 2-pole winding the
extract-speed. When operating with load, the
speed deviates slightly from the synchronous
(no-load) speed. This difference is called the slip
and is usually expressed as a percentage of the
syncronous speed. The motors will work satisfactorily at nominal voltage +10%-15%.
Function of single-phase motor
When the stator winding is charged without a
capacitor, two counteracting magnetic fields are
created. When a capacitor is connected, it will
displace one of the two magnetic fields adding it
to the other, creating a torque turning the rotor in
a specific direction. The RPM is the same as for
the 3-phase motor.

Motor connections
1, 2 and 3: wash speed (18-pole winding).
4, 5 and 6: extract speed (2-pole winding)
7 and 9: motor overload protector.
Motor overload protector
The motor is equipped with two self-resetting,
thermal overload protectors, situated one in each
of the windings of the stator. The protectors are
connected in series and will trip at a temperature
of 120°C (248°F) (3-phase) or 130°C (266°F)
(single phase). In the event the protectors fail
but the motor remains otherwise undamaged, an
overload protector may be mounted in the control
unit of the machine. Before making such installation check to ascertain that the windings are not
damaged. A burned out motor can be re-wound.
NOTE
Before connecting a separate overload
protector consult the local code.
Single-phase W125 and W185 machines are
also equipped with a manually set overload
protector mounted on the extract relay in the
control unit. This overload protector protects the
motor during the start-up of the extraction.
Removing the motor
• Remove the drain valve (1) from the long shaft
by pulling it straight up.
• Remove the tensioning unit (2) on the rear of
the motor.
• Disconnect the connector (3) placed
diagonally under the rear edge of the motor.
• Remove the two screws (4). Pull the shaft
forward slightly until the guide pins pull out of
the shaft brackets. Remove the motor unit.

Water level controls
One pressure switch is used to control the correct water levels
during various cycles of the washing program.
Adjustment
All pressure switches are factory-calibrated to meet specific
requirements. The trip level for any one pressure switch can be
changed only within narrow limits because each trip range requires a different set of springs.
Water level
As a guide for checking the level control for proper functioning, the
normal level should be at the bottom of the door glass.

Inlet valves
Construction
The valve has a single-inlet with either one, two
or three outlets, each with its own solenoid coil.
The body is made of heat-resistant polyamid
plastic and the solenoids encased in water-tight
plastic.
A filter screen on the inlet side prevents dirt from
entering the valve. Flow restrictors can be placed
at either the inlet or any of the outlets.
Operation
When the solenoid is energized, the springloaded plunger is drawn up and the pilot valve in
the center of the diaphragm open. Because of
the difference in diameter between the pilot valve
opening and the ventilating hole in the diaphragm, the pressure above the diaphragm drops
to a point where the admission pressure below
the diaphragm can lift the diaphragm, thus opening the valve.
When the current to the solenoid is cut off, the
plunger spring will press the plunger against the
pilot opening of the diaphragm. The pressure
above the diaphragm then rises to correspond to
the water inlet pressure and the pressure of the
spring will close the valve.

Maintenance instructions
Limescale can block the hole in the valve diaphragm and interfere with the function of the valve.
It is therefore advisable to dismantle and clean
the valve at certain regular intervals. The frequency depends on operating conditions and the
level of contamination in the water.
Trouble shooting
If the valve does not open
• Check that power is supplied to the coil.
• Check the coil with an instrument to determine
whether there is a break or a short circuit.
• Dismantle the valve (see below) and check
the openings in the valve diaphragm.
• Check the inlet strainer and clean as required.
• Undo the coil and clean the surfaces of the
magnetic core.
If the valve does not close
• Check that the coil is not live. The valve is
normally closed when the magnet is not
energised.
• Check the return spring.
• Check the diaphragm (pilot pressure opening).
Dismantling the valve
• Pull the coil straight upwards. Use a screwdriver if necessary to carefully undo the coil.
• Use the tool supplied with the machine
(attached to one of the hoses when the
machine is delivered) to open the valve
housing. Slide the tool over the protruding
plastic sleeve to that the pegs on the tool
engage the corresponding sockets in the
valve housing.
• Use a spanner or a pair of pliers and unscrew
the upper part of the valve housing.

Inlet valve for W75-W185
The water inlets have brass bodies with larger
cross section of the outlet in order to achieve a
shorter filling time for the machine.
Construction
The valve housing is made of pressed brass. The
spring-loaded plunger is made of stainless steel
and located at its lower end.
Operation
The valve is automatically operated by means of
a rubber diaphragm and a pilot valve in exactly
the same way as the supply injector valve.
NOTE: To strip, clean, re-assemble and
troubleshoot the inlet valve, follow the

Drain valve
Description
The drain valve is operated by using the pressure
in the cold water intake. A tube (1) is connected
between the cold water intake and a solenoid
valve (2). When the solenoid valve is activated,
it opens and allows water to flow into the feeder
tube (3). The water presses up a piston (4),
which uses the pressure lid (5) to close the drain
valve rubber membrane. When the solenoid
valve cuts out, the water presure and the springs
(7) on the lid push the piston back, allowing the
water to pass the solenoid valve and drain out via
the return tube (8).
Trouble shooting
If the drain valve doesn’t close:
• Check that the solenoid valve (2) receives
electricity.
• Check that the solenoid valve and the tubes
are clear by:
- removing the drain hose (3).
- Check that water exits the hose when the
valve is activated.
• Check that the diaphragm (9) is undamaged.
If the drain valve doesn’t open:
• Check that the return tube (8) is open.
• Check that the piston (4) doesn’t seize.

Maintenance
Preventive maintenance has been reduced to a
minimum by the careful design of reliable components and material.
However, the following measures should be
taken at regular intervals and in proportion to the
hours of service.
IMPORTANT!
Make certain that all electrical power to
the machine is shut off before removing
top or rear panels.
Daily
• Check the door lock and interlock before
starting operations.
• The soap supply box should be cleaned at the
end of each working day as follows:
- Use a spatula to scrape loose any deter-
gent which may have stuck on the inside of
the dispenser.
- Flush the loosened detergent with warm
water.
- Wipe dry and leave lid open.
• Check that the drain valve does not leak and
that it opens properly.
• Check that the door does not leak. Clean
residual detergent and foreign matter from the
door gasket.
• Wipe the outside of the machine.
• When the machine is not in use, leave door
slightly open to allow moisture to evaporate.
Weekly
• Remove the hose from the drain connection
and clean the inside of the drain valve.
Every three months
• Remove the rear panel of the machine and
check that the V-belt of the wash motor is
undamaged and correctly tensioned.
• Check that all tubing, piping and connections
are free from leaks.
• Wipe and clean the inside of the machine,
making sure that the control components are
protected from moisture and dirt during the
cleaning operation.

If the machine does not start
A Check circuit breaker in the power feed line to
the machine.
B Check the door safety switches.
C Check the glass cartridge fuse.
If water does not drain
A Check the drain valve and drain solenoid for
proper operation.
B Disconnect the drain hose connected to drain
line. If full flow of water comes out, the pro-
blem is in the main waste line. If water flow is
slow, the problem is the accumulation of
foreign materials between the drain valve and
shell outlet of machine. Clean valve body of
any foreign objects found.
