Machine Foundation
The machine must be secured to a foundation or floor
of adequate construction. Detail must be stressed with
all foundation work to ensure a stable unit installation,
eliminating possibilities of excessive vibration. 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. Do not support the
machine on only four points. Anchor bolts must be a
minimum of 3/4 inch diameter, grade 2. Refer to
Mechanical Installation.
A base designed to elevate the UW50 to a comfortable
and more accessible height for loading and unloading
laundry may be used. Care must be exercised in the
design of such a base due to the force exerted by the
machine during extract (222 Gs).
Static and dynamic loads on the floor or foundation are
shown in Table 2. This table can be used as a reference
when designing floors and foundations.
NOTE: Machine must be installed on concrete floor
that is a minimum of 12 inches thick. Do not mount
on wooden floors. Do not install above ground floor.
Floor must be solid.

Mechanical Installation
A proper foundation is absolutely necessary for the
UW50P-4 due to its high extract speed and the G-force
exerted.
A bolt kit is available as an option consisting of eight
3/4 inch bolts, 8 inches long, which should be
imbedded in a reinforced concrete floor that is a
minimum of 12 inches thick.
Figure 1
Figure 2
The threaded end of the bolts should extend 2 inches
above the surface of the floor. Refer to Figure 3 for the
location of these bolts. A bolt locator fixture (base
frame), consisting of a rigid welded assembly made of
reinforcing rod welded to the eight 3/4 inch bolts
which may be embedded in the concrete as one piece
is also available as an option. Refer to Figure 2. Be
sure the bolt threads also extend 2 inches above the
floor.

If the existing floor is not reinforced concrete a
minimum of 12 inches thick over a solid base, it will
be necessary to cut a hole through existing floor
approximately 5 feet square and excavate to a depth of
36 inches from top of existing floor. Slope the edges of
the hole outwards so that the hole is pyramid shaped.
Excavate under existing floor 5 inches beyond the
required 5 feet square all around. Refer to Figure 4
where x = 5 feet.
Refill with 24 inches of well compacted clean fill dirt
topped with 12 inches of reinforced concrete. Imbed
mounting bolts or base frame when pouring concrete.
Make sure that the bolt threads extend 2 inches above
the floor level.
After the foundation for the machine has been
prepared and the concrete has cured, proceed as
follows:
1. Place the machine adjacent to the foundation. Do
not attempt to move the machine by pushing on
the sides. Always use a pry bar or other device at
the bottom of the machine. Remove the wood
skid.

2. Set machine over bolts and shim the machine so
that it sits level and is 1/2 inch off the floor.
Apply machine grout between the floor and all
frame members of the base of the machine
(remove front panel and expanded metal back
panel to gain access to all frame members). Force
grout under machine base until all voids are
filled. Refer to Figure 5.
Leave a small opening for water drainage at the
rear of the machine. Do not omit this step.
3. After grout has cured, place washers and nuts on
bolts and tighten securely. Be sure nuts are
tightened evenly all around. DO NOT DISTORT
MACHINE BY BOLTING DOWN ON AN
UNEVEN FLOOR SURFACE.
NOTE: Make sure to retighten the anchor bolts
after a few days of operation.
Drain Connection
Providing an adequate drain arrangement and capacity
is essential. Ideally, the machine should dump through
a 3 inch pipe directly into a sump or floor drain.
Connection to a drain must be vented to prevent an air-
lock or siphon effect and must be flexible. Increasing
drain hose length, installing elbows or causing bends
will decrease drain flow rate which might harm washer
performance. If the drain arrangement is inadequate,
the machine will not extract properly nor will it
discharge all the water. If proper drain line size is not
available or practical, a surge tank of adequate design
would be required.

Water Connection
Separate hot and cold plumbing lines (3/4 inch pipe or
larger) with individual shut-off valves must be
provided. Hot water should be a minimum of 160°F.
Best performance will be realized if water is provided
at a pressure of 30-85 psi. Although the machine will
function properly at a lower pressure, excessive fill
times will occur.
Use flexible hoses or equivalent flexible lines. The
hoses should hang in a large loop. Do not allow to
kink.
Flush the water system and check filters in machine
inlet hoses for proper fit and cleanliness before
connecting.
The UW50 has a total of four hose connections. Each
pair of hoses is connected to a hot and cold water
faucet with a 3/4 inch hose bib. Each machine requires
incoming water connections as follows:
Four 3/4 inch faucets with 3/4 inch hose bib
connected to two 3/4 inch hot water faucet lines and
two 3/4 inch cold water faucet lines.
Figure 9
Each of the hoses should have a screen filter installed
to keep rust and other foreign particles out of the
solenoid valves. These connections should be supplied
by a hot and a cold water line at least 3/4 inch size for
each. Installation of additional washers will require
proportionately larger water lines. Refer to Table 3.
Suitable air cushions should be installed in supply
lines to prevent “hammering.”If the water pressure is
above 60 psi, flexible copper tubing should be used in
place of the rubber hoses.

For voltages above or below listed specifications,
contact Customer Service or a distributor for buck/
boost transformer recommendation.
If machine is intended for four-wire service, a neutral
leg must be provided by power company.
If a delta supply system is used on a four-wire model,
connect high leg to L3.
IMPORTANT: Improper connections will result in
equipment damage and will void warranty.
Connection Specifications
IMPORTANT: Connection must be made by a
qualified electrician using wiring diagram provided
with machine, or according to accepted European
standards for CE-approved equipment.
Connect machine to an individual branch circuit not
shared with lighting or other equipment. Shield
connection in a liquid-tight or approved flexible
conduit. Proper conductors of correct size must be
installed in accordance with National Electric Code or
other applicable codes.
Use wire sizes indicated in the Electrical Specifications
chart for runs up to 50 feet (15 m). Use next larger size
for runs of 50 to 100 feet (15 to 30 m). Use two sizes
larger for runs greater than 100 feet (30 m).
The UW50 is provided with a thermal overload
protector in the drive motor windings and a separate
fuse for the control circuit. However, a separate three-
phase circuit breaker must be installed for protection
against shorts. DO NOT USE FUSES.
For proper over current protection, the circuit breaker
should be a 30 Amp capacity unit rated for
208-240 Volts and should be a three-phase breaker so
that in the event that one leg should be removed from
the machine, all three legs will be disconnected to
prevent damage to the motor.
The wire for the service connection should be a
minimum size of 8 gauge (AWG) for 208-240 Volt
installations. Refer to Table 7.
The connections should be made by a qualified
electrician and in accordance with the wiring diagram
provided with the machine.
When the machine is started, check that the cylinder
rotates in the correct direction during the spin (extract)
step, i.e., clockwise as seen from the front of the machine.
If the machine rotates in the wrong direction, two of
the lines are to be interchanged at the power connection
terminal (reverse L1 and L2 –do not reverse L3).

For Machines with Electric Heat
Use wire size indicated in Table 7 for runs up to
50 feet. Use next larger size for runs of 50-199 feet.
Use two sizes larger for runs greater than 100 feet.
This protects against voltage drop which would result
in a reduction of starting toque.
Electrical connections are made at the J-box located on
the rear of the control module. The machine must be
connected to the proper electrical supply shown on the
identification plate attached to the side of the control
module.
Figure 11
Do not connect the ground to the neutral (N-white
wire) leg at the J-box terminal strip. If the machine is
intended for 4 wire service, a neutral leg must be
provided by the power company. Do not connect the
neutral leg to the ground lug.
If a Delta Supply System is used, the high leg must be
connected to the red wire (L3) at the J-box terminal
strip. If three-phase service is not available and a Roto-
Phase or other phase adder is used, the artificial leg
must be connected to the red wire (L3).
