Introduction
The EX-HI-TEK model washer/extractor has been developed to cover the
heavy duty requirements of hotels, motels, nursing homes, hospitals,
professional laundries, restaurants, airlines, steamships, schools, colleges and
all on-premises laundries where flexibility and quick formula variation, coupled
with high quality automatic washing, are required.
The microcomputer controlled EX-HI-TEK model allows for complete
programming of water temperatures, water levels, wash and extraction periods
and supply injections.
The machines are free-swinging, i.e., the drum is moveable and spring
suspended in relation to the frame. This minimises vibrations transferred to the
frame thus simplifying installation, as no concrete base is required.
The high speed spin gives a G factor of approximately 300, providing very
efficient water removal during the spin.
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 Wascomat for any purpose always
give the machine serial number, model, voltage and other electrical
characteristics appearing on the nameplate at the rear of the machine.

Electrical installation
Although the machines are fitted with thermal
overloads in the motor windings and separate
fuses for the control circuit, a separate threephase 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.
The machine is equipped with a control circuit
transformer, mounted on the control unit and
connected for 220 volt operation. If your
incoming voltage is below 210 volts move the
wire connection to the 208 volt tab on the
transformer. If it is above 230 volts move the
wire to the 240 volt tab on the transformer.
Check the incoming power for a high voltage leg.
If present, connect that line to L2 on the terminal
block. Make certain it is not connected to the
transformer.
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.
To ensure proper operation the drum must
rotate counter-clockwise (seen from the front)
during extraction. If the drum rotates in the wrong
direction interchange line L1 and L3 at the power
connection terminal.

Mechanical and electrical design
General
This machine is a free-swinging model i.e. the outer drum and motor bridge are
suspended in the machine chassis via a spring suspension with a strong spring in
each corner of the machine. Each spring has a shock absorber which dampens the
movement of the machine.
The inner drum is driven by two motors via a V-belt: one motor for washing and
distribution speed and one for extract speed. The inner drum is mounted in the
outer drum with two heavy duty bearings at the back plate and is sealed with two
V-rings.
The two motors are suspended underneath on a motor support with a belt
tensioning device. The motors are mechanically coupled to each other with V-belts.
During wash and distribution speed the spin motor transmits power to the drum,
through a clutch arrangement.
The water inlet and drain are both situated under the outer drum. This improves the
flow during filling and prevents water vapour from entering the detergent
compartment.
The robust square door is locked with a handle which is interlocked by a safety
device when the machine is running.
The manual push buttons and card programmed control are fitted at the front of the
machine.
All control and indicating components i.e. relays, delay unit, etc. are assembled
under the top cover, easily accessible from the top of the machine for simplified
servicing.
The machine housing consists of hot-dip galvanised, painted steel plates and
stainless steel sheets, painted on the front and sides. It has a stainless door (and
front, on request).

Frame
Description
The frame is constructed on the free-swinging principle, i.e. the washing
drum is freely and resiliently suspended in the fixed frame.
The entire frame is constructed of U-shaped iron beams forming a stable
and torsionally rigid structure.
The suspension device for the drum unit and motors consists of four posts,
one in each corner, each with a robust spring to which the washing drum
supports are attached. In order to prevent excessively great vibrations
which can be caused by imbalance in the drum, a shock absorber is fitted
between the drum and frame by each spring. (The EX 12 model has twin
shock absorbers at the front.)
Repair instructions
If the out-of-balance cutout is repeatedly triggered
• Check the shock absorbers, replace them if required. Note that the
shock absorbers should be fitted with the plunger rod upwards.
• Check the attachment of the springs:
- the spring is attached by a bolt from above: Check that it has been
properly tightened down.
The entire spring unit should be replaced in spring replacement.

Drum with bearings
Description
The inner drum is journalled to the outer drum by two robust bearings in a
bearing housing which is bolted to the rear plate. The bearing unit supports the
drum without any support being needed at the front. Shaft seals of the V-type, as
well as O-rings, seal against leakage.
The space between the bearings is packed with grease during assembly. No
additional grease is required.
The inner drum shaft is continuous, and the V-belt pulley is attached to the
protruding journal by an adapter sleeve.
The outer drum end plate consists of two parts, the inner and outer end plates
which are bolted to the bearing housing with through bolts. NOTE: The inner and
outer end plates must not be taken apart when the bearings are replaced.
The outer drum and rear plate are held together by 3 straps.
The outer drum is connected to its resilient suspension by four supports, bolted to
the end plates. It is important that these supports are not loosened from the rear
plate during repairs.
