1.7 INPUT AND OUTPUT SERVICES
1. Water pressure
Best performance will be realized if water or provided at a pressure of 30 – 87psi (2 – 6
bar). Although the machine will function properly at lower pressure, increased fill time will occur.
Water pressure higher than 120 psi (8 bar) may result in damage to machine plumbing components
failure (s) and personal injuries.
2. Optional Steam heating pressure
Best performance will be realized if steam pressure is provided at a pressure of 30 – 80 psi
(2 – 5.5 Bar). Steam pressure higher than 125 psi (8.6 Bar) may result in steam components and
may cause personal injuries. For machines equipped with optional steam heat, install piping in
accordance with approved commercial steam practices. Failure to install the supplied steam filter
may void the warranty.
3. Compressed Air
For machines requiring compressed air service, best performance will be realized if air is
provided at a pressure of 58 – 87 psi (4– 6 Bar). Large capacity machines could experience door
seal failures if compressed air service is interrupted.
4. Drainage System
Provide drain lines or trough large enough to accommodate the total quantity of water that
could be dumped if all machines on the site drained at the same time from the highest attainable
level. If drain troughs are used, they should be covered to support light foot traffic.
5. Power
For personal safety and for proper operation, the machine must be grounded in accordance
with state and local codes. The ground connection must be to a proven earth ground, not to
conduits or water popes. An easy – access disconnect switch should be provided.
Ensure that a ground wire from a proven earth ground is connected to the ground lug in the
electrical junction box on this machine. Without proper grounding personal injury form electrical
shock could occur and machine malfunctions may be evident. Computer – controlled machines
must have a proper ground to prevent computer malfunctions.
Always disconnect power and water supplies before a service technician
performs any service procedure. Where applicable, steam and / or compressed air
supplies should also be disconnected before service is performed.
1.8 AC INVERTER DRIVE
Machines equipped with AC drives require special attention with regard to the operating
environment.
1. An especially dusty or linty environment will require more frequent cleaning of the AC drive
cooling fan filter and of the AC drive itself.
2. Power line fluctuations from sources such as an interruptible power supplies (UPS) can
adversely affect machines equipped with the AC drive. Proper suppression devices should be
utilized on the incoming power to the machine to avoid problems.

IMPORTANT INFORMATION
1-5
3. A clean power supply free from voltage spikes and surges is absolutely essential for machines
equipped with the AC drive. Nonlinear inconsistencies (peaks and valleys) in the power can
cause the AC drive to generate nuisance errors. If voltage is above 230V for 200V installations
or above 440V for 400V installations, a buck / boost transformer is recommended. If voltage is
above 240V or 480V, a buck / boost transformer is required unless the factory advises
differently.
4. Sufficient space to perform service procedures and routine preventive maintenance is especially
important for machines equipped with AC drives.
1.9 MACHINERY MISUSE
Even though this machine is an atmospheric vessel, never use it for any purpose other than
washing fabrics.
1. Never wash petroleum – soaked rags in the machine. This could result in an explosion
2. Never wash machine parts or automotive parts in the machine. This could result in serious
damage to the basket.
3. Never stone wash in the machine. It could wear the basket and serious damage might occur to
the machine.
4. Never use the machine for dying and with harsh chemicals that can cause corrosion and other
health hazards.
5. Never allow children to play on or around this machine become trapped in the machine. Do not
leave children unattended while the machine door is open. These cautions apply to animals as
well.
1.10 THEORY OF OPERATION
The HARDMOUNT Series washer – extractors use a single – speed motor to drive the
cylinder via V – belts in all speeds. The cylinder is supported by two spherical roller bearings
located in a bearing housing made of cast iron.
The motor is controlled by the computer control located in the front and the AC inverter
drive located in the rear panel. Any speed can be programmed for any wash cycle. Some speed
ranges are blocked out for programming due to safety reasons. These speed ranges are ones that the
machine cannot operate at due to its spring or suspension resonance. This speed range is not
important and normal speeds for wash or extraction are not within this range. Any wash speed in the
range of 3 – 50 RPM and extraction speeds 150 – maximum RPM can be programmed. Further, any
reversing action can be programmed. Normal reversing action is 16 seconds forward, pause for 4
seconds, and 16 seconds reverse. Any temperature between 70 °F to 200 °F (20 – 95 °C) can be
programmed. Any water level in the range of the machine parameters can be programmed in
centimeters. The computers will automatically provide safety levels for steam injections and door
operations.
Water entry into the machine is through electromagnetic water valves controlled by the
computer. The computer also controls the drain, supply dispenser, any external liquid supplied,
steam injection and any other vital functions of the wash program. The computers can even record
cycles and data of importance that could be used for maintenance purpose.
The steam, if installed is injected in the bottom of the shell via a steam injector. The steam is
controlled by a steam valve that is programmed by the micro computer.
The cylinder is perforated, allowing water to pass through and drain from within during
drain and extract steps. Lifting ribs inside the cylinder lift the load from the wash solution and allow

the load to tumble and falling back into the solution when the load reaches the approximate
10 – 11 o’clock or 1 – 2 o’clock positions. This mechanical action removes soil from the fabric.
Furthermore, the lifters are perforated on the top so that water can cascade over the goods and wet
them quickly. This reduces water consumption as water is picked up at the cylinder’s lowest point
and lifted and splashed over the goods at the highest point as the cylinder rotates.
A stainless steel door is provided for loading and unloading. A door lock system prevents
operation of the machine when the door is open. The door is locked during operation utilizing an air
cylinder and a manual latch for safety reasons. The door lock is provided with magnetic sensor to
indicate that the machine is locked and provide for start of the machine when the door is closed and
locked.
The AC drive, contractor, circuit overload protectors, input power supply connections,
external supply connection, and control transformer are behind a cover of the rear of the machine.
Pneumatic controls together with the air pressure regulator for the door seal are also located here.

3.2 MACHINE FOUNDATION
A proper foundation is an absolute necessity when installing a fixed mount washes
extractor. Do not neglect details when doing foundation work. These details will ensure a stable
installation, reducing the possibility of excess vibration at high speeds.
The machine must be anchored to a smooth level surface so that the entire base of the
machine is supported and rests on the mounting surface.
NOTE: Do not support the machine at only four points.
A concrete base designed to elevate the washer-extractor to a more comfortable working
height may be used. Use care when designing a base, as the forces generated during extract are
extreme. The base must be adequately tied into existing floor.
The factory can provide, at extra cost, elevated base frames designed to handle the extreme
forces encountered during the extract phase of the cycle. Using other non – factory designs can cause
undesirable operation, machine damage, and in extreme circumstances, injury or death. Damage
caused by use of non – factory base frames is not covered under warranty.
Do not attempt to install this machine on wooden flooring of any kind, above ground level,
or over basements. Installation must be slab on grade or equal.
Ensure that the machine is installed on a level floor of sufficient strength and that the
recommended clearances for inspection and maintenance are provided. Never allow the inspection
and maintenance space to be blocked.

1. Remove the wood skid by unscrewing the carriage bolts holding it to the bottom frame concrete
base of the machine.
2. Carefully place the machine over the anchor bolts. Raise the machine and level it 1/2 inch above
the concrete base on four points, using spacers that can be removed easily.
3. Fill the spaces between the machine base and floor with machinery grout. Remove front panel
and rear panel to gain access to all frame members. Grout completely under all frame members.
Force grout under the machine base until all voids are filled.
4. Remove the spacers carefully, allowing the machine to settle into the wet grout.
5. Place the Large hardened flat washer over the Archer bolt. Erasure there is no grout in and
around the Archer bolt in the hole. If there is, clean it out so Lange flat washer makes contact
with the machine base plate upper surface.
6. Attached the mounting bolt washers and lock nuts to the anchor bolts after the grout has
hardened. Tighten the lock nuts by even increments-one after the other-until all are tightened
evenly and the machine is fastened securely to the floor. The nu1s should be tightened in a
diagonal fashion, which will help ensure equal tension at all anchor points.
3.3 MOUNTING BOLT INSTALLATION
All washers – extractors must be secured by the use of inlayed J – Bolt or similar fixing
method. The anchors should be embedded in 3500 psi (24000 N/m2) reinforced concrete. See Figure

3.3.1 MACHINE BASE MOUNTING HOLE CONFIGURATION
Below are the standard hole configurations for the HARDMOUNT Series mounting.
Fig. 3-5 Bolt hole layout
3.4 DRAIN CONNECTION
A drain system of adequate capacity is essential to the machine performance. Ideally the
water should empty through a 4 inch vented pipe directly into a sump or floor drain. See figure 3-6.
•A flexible connection must be made to a vented drain system to prevent an airlock or
siphon effect. If proper drain size is not available or practical, a surge tank is required. A
surge tank in conjunction with a sump pump should be used when gravity drainage is not
possible, such as in below – ground – level installations.
•Before any deviation from specified installation procedures is attempted, the customer or
installer should contact the manufacturer. Increasing the drain hose length, installing
elbows, or causing bends will decrease drain flow rate and increase drain time, impairing
machine performance. If the drain arrangement is inadequate, the machine will not
extract and will not discharge water properly.

3.5 ELECTRICAL INSTALLATION
The AC drive requires a clean power supply free from voltage spikes and surges. A voltage
monitor should beused to check incoming power. The customer local power company may provide
such a monitor.
The AC drive provides for an internal circuit breaker. A separate circuit breaker governs the
control circuit.
If input voltage measures above 230V for a 200V drive, or above 440V for a 400V drive,
either ask the power company if their representative can lower the voltage or install a step – down
transformer kit available from the manufacturer. Voltages above 250V and 490V require additional
measures. Contact the distributor or the manufacturer for assistance.
This machine must be installed, adjusted, and serviced by qualified electrical
maintenance personnel familiar with the construction and operation of this type
of machinery. They must also be familiar with the potential hazards involved. If
this warning is not observed, personal injury or equipment damage resulting in
voiding the warranty may result.
When controlling the AC drive with a parameter unit, the machine’s computer
and its safety features are bypassed. This would allow the basket to rotate at high
speeds with the door open. When using a parameter unit to control the AC drive,
a large sign should be placed on the front of the machine warning people of the
imminent danger.

Never touch terminals or components of theca AC drive unless power is
disconnected and the “CHARGE” indicator LED is off. The AC drive retains
potential deadly voltage for some time after the power is disconnected. There is
no user –
serviceable parts inside the AC drive. Tampering with the drive will
void the warranty.
Dangerous voltages are present in the electrical control boxes and at the motor
terminals. Only qualified personnel familiar with electrical test procedures test
equipment, and safety precautions should attempt
adjustments and
troubleshooting. Disconnect power from form the machine before removing the
control box cover, and before attempting any service procedures.

NOTE: For single phase (1Ø) operation, connect input power to L1 and L2, leaving the L3
terminal open.
NOTE: Wire sizes shown are for copper, THHN, 90 conductor per NEC article 310 (USA).
The machine should be connected to an individual branch circuit not shared with lighting or
other equipment because this is a vibrating machine, the use of SO cable or similar, with a twist –
lock plug, to connect the machine to main power is recommended. A shielded liquid tight or
approved flexible conduit with proper conductor of correct size installed in accordance with National
Electric Code (USA) or other applicable codes is also acceptable. The connection must be made by
a qualified electrician using the wiring diagram provided with the machine. See the electrical
connection data chart for correct wire sizes.
Use wire sizes indicated in the chart for runs up to 50 feet (15 m). Use next larger size for
runs of 50 to 100 feet (15 – 30 m). Use 2 sizes larger for runs greater than 100 feet (30 m).

INSTALLATION PROCEDURES
3-8
For personal safety and for proper operation, the machine must be grounded in accordance
with state and local codes and in the USA in accordance with the National Electric Code, article
250 – 96.
The ground connection must be to a proven earth ground, not to conduit or water pipes.
Do not connect the system is used, the neutral (N) leg at the terminal strip.
If a DELTA supply system is used, the high leg may be connected to L1, L2 or L3, as the
machines are equipped with control transformer.
Insure that the control transformer taps are connected in accordance with the incoming line
voltage. Verify connections as shown on the schematic with each machine.
Fig. 3-7 Electrical Service Connection Detail
3.6 WATER CONNECTION
Individual hot and cold plumbing lines with individual shut – off valves must be available to
the machine. Hot water should be minimum of 160 °F (70 °C). If lower temperature water is used
the machine should be equipped for steam heating to heat the wash solution to desired temperature.
Best performance will be realized if water is provided at a pressure of 30 – 87psi (2 – 6Bar).
Although the machine will function properly at lower pressures, increased fill times will occur.
Flush the water system for at least two minutes prior or initial use.
Use flexible hoses and install separate screen filters in the lines to keep rust and other foreign
particles out of the solenoid valves. Hang the hoses in a large loop. Do not allow the hoses to link.
The water connections to the machine should be supplied by a hot and cold water line of least the
sizes shown in the table below. Installation of additional machines will require proportional larger
water lines.
