Introduction
Introduction
Fig.
The Flex-O-Matic models washer/extractors have been developed to cover
1
the heavy duty requirements of hotels, motels, nursing homes, hospitals,
professional laundries, restaurants, airlines, ships, schools, colleges and all
on-premises laundries where flexibility and quick formula variation coupled
with high quality automatic washing are required.
The card-programmed FL-model allows for complete programming of water
temperatures (only heated machines), water levels, wash and extraction
periods and supply injections. The machine is designed for connection to
hot and cold water supplies and may be used with free-standing powder or
liquid supply injectors which can be activated by signals from the machine.
All parts of the machine which come into contact with the items being
washed are made of heavy gauge surgical stainless steel, ensuring long life
and lasting beauty, as well as full protection for no-iron fabrics. All electrical
components are made accessible for servicing by simply removing the top
panel.
This manual contains a technical description of the machine and instructions for its installation, operation and maintenance. Together with the
wiring diagram which accompanies each individual machine it should be
kept in a safe place for easy reference.

When ordering spare parts or contacting the manufacturer for any purpose
always give the machine serial number, model, voltage and other electrical
characteristics appearing on the dataplate at the rear of the machine.
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:
Fig.
1. Decide where to place the machine and
2
Fig.

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.
Use the template to position the foundation

Door, description
Fig.
The door consists of a backing frame (1), door
(2), glass (3) and door gasket (4). The backing
34
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
Fig.
The door lock consists of a circuit board (1) with
a connector. Mounted on the board are the lock
35
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:
NOTE
Do not repair a faulty door lock.
Allways replace the old unit
with a new one, to assure proper operation of the door safety
interlock.

•When the door is closed and the door handle
is turned to move the locking bolt to the
locking position, the micro switch is activated
indicating that the door is properly shut.
•When the machine is started by turning the
programmer knob to the ON position. Power is
removed from the locking device solenoid,
allowing the locking device to come forward
and engage the locking bolt in the locking
position. 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 bi-metallic 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
Fig.
The Flex-O-Matic models employ four relays.
37
The relays control:
•the wash speed (1)
•the extract speed (2
•the drain
•the re-start
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.
37
3
4

2
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
Fig.
If the relay fails to operate despite power to the
coil, turn off the power and check the solenoid by
38
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
Fig.
The motor is mounted on an axle with rubber
39
dampeners.
The V-belt is tightened by turning the motor on
Fig.
the axle and locking it in place using the
40
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.
39
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
1729
40
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 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.

Water level controls
Fig.
One triple-level pressure switch controls the low and high water
levels during various cycles of the washing program, and that
44
there is water in the drum before flushing detergent starts.
One double-level pressure switch checks that there is no water in
the drum before the door can be opened and does not allow the
machine to start extraction with water in the drum.
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
low level should be at the bottom of the door glass, and the high
level approximately three inches above it.

Rotation guard
The rotation guard checks that the drum is completely at a standstill before the
door can be opened. When the drum has been still for approx. 2 seconds the coil
in the door lock is activated and the lock can be opened (providing the water has
emptied and the programmer has reset). This guard also checks that the drum is
actually rotating when the wash or extraction relays are operating.
The rotation guard consists off a circuit board located in the automatic unit and a
Fig.
pulse generator mounted in a holder on the rear of the machine. There is a magnet
45
on one of the spokes of the belt pulley. Each time this magnet passes the pulse
generator, a contact within the pulse generator closes and a pulse is sent to the
rotation guard.
The rotation guard exists in two versions, one for machines with an auxiliary transformer, the other for machines without. The two differ in the way that certain straps
on the circuit board are arranged. Also, the version for machines with transformer
has an LED which indicates error status on the board. The two versions are
described on the pages which follow.

Mechanical and electrical desing
Rotation guard for machines without auxiliary transformer
When the machine has halted, the rotation guard relay K1 is closed which
Fig.
means that the door lock coil Y4 will be energised an the door can be opened.
46
Since the wash and extraction relays are not closed, relay K3 is not energised.
When the machine starts and pulses are received from the pulse generator,
relay K1 will switch immediately and it will not be possible to open the door.
Since the machine's wash or extraction relay is energised, relay K3 closes after
a delay of approx. 2 seconds.
The rotation guard also checks that the drive belt has not broken. It works as
follows: relay K3 is closed when the machine is working. If the belt breaks, the
drum stops and the pulse generator stops transmitting pulses.
After 2 seconds relay K1 closes. When this happens the circuit between phase
(L1) and neutral (N) closes. The current increases so that main fuse F11 blows.
The machine stops and the door remains locked until the bimetallic strip in the
delay unit has cooled.

Inlet valves
Construction
Fig.
The valve has a single-inlet with either one, two
or three outlets, each with its own solenoid. The
47
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 spring-
Fig.
loaded plunger is drawn up and the pilot valve in
48
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.
Fig.
It is therefore advisable to dismantle and clean
the valve at certain regular intervals. The fre-
49
quency 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
Fig.
•Pull the coil straight upwards. Use a screwdri-
50
Fig.
51
ver 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 FL185
Fig.
The water inlets have brass bodies with larger
cross section of t˛e outlet in order to achieve a
53
shorter filling time for the machine.
Construction
The valve housing is made of pressed brass. The
spring-loaded plunger is made of stain-less steel
and located at its lower end is a rubber gasket for
the pilot valve.
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
instructions autlined for the supply injector
valve.
Clean out
52
0311
53
At water temperatures of more than 60°C/140°F,
the lime deposits are heavily increased. This can
cause function problems due to blocking up the
equalizing orifice of the valve.
Fig.
The fault can be eliminated by cleaning the
52
equalizing orifice (marked A).
Fig.
If there are much deposits the orifice can be
changed from 0.5 mm to 0.8 mm. The screwhead
53
of the orifice is marked with 1 ring for the size of
0.5 mm and 2 rings for the soze of 0.8 mm.
Clean the orifice as follows:
1. Shut off the main supply.
2. Unscrew the orifice.
Fig.
3. Clean the hole in the orifice carefully with a pin
54
or similar not thicker than 0.5 resp. 0.8 mm.
4. Mount the orifice, be careful with sealing and
tighten.
5. Open the main supply.

Drain valve
Description
The drain valve is operated by using the pressure
Fig.
in the cold water intake. A tube (1) is connected
56
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:
56
-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.

Card programming
General
Programmable cards are used to control the various
Fig.
sequences in a washing cycle. These have 16 ribs
67
with pegs which act on the programmer integral
micro-switches. Each rib has its own function. The
card is fed through the programmer using
mechanically transferred impules from the programmer motor.
A function is selected by punching out one or more
pegs depending on the amount of time desired.
The rib are marked A through Q. In order to pinpoint function change-overs in time, every fifth peg
is numbered along one edge using two different
scales. One is for direct number identification of the
pegs and the other to identify peg-number in relation
to the front plate of the programmer.
Programming, when using powder supply
Rib function description:
A -For powder supply: Flushing detergent from
compartment 1. Programmed for 30 seconds
together with water filling. If the water pressure
is low, deter- gent supply should occur after
water filling. Detergent supply can not be
programmed before water filling. If external
liquid supply us used, signal is given to
connection 1.
B -Thermostat 1 (Only heated machines).
Desired temperature is set on the upper
thermostat dial. Heat should be programmed
after water filling and the appropriate detergent
compartment has been emptied.
C -For powder supply: Flushing detergent from
compartment 2. See rib A for programming.
(*If external liquid supply is used, signal is
given to connection 2).
D -Thermostat 2 (Only heated machines). Desi-
