Introduction

Introduction
The Selecta models 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-premi-
ses laundries where flexibility and quick formula variation, coupled with high
quality automatic washing, are required.
The machines are free-swinging, i.e., the drum is moveable and spring suspen-
ded in relation to the frame. This minimizes 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 characteris-
tics appearing on the nameplate at the rear of the machine.

IMPORTANT
NOTICE
This machine is equipped with an automatic oiler,
located at the right rear of the machine, which keeps
it lubricated for long bearing and seal life.
The amount of oil in the container is sufficient for
approximately one year's lubrication. It is of utmost
importance that the oiler does not become empty.
Therefore we recommend that the rear panel be
removed and a visual inspection made on a
bimonthly basis. When the oil reaches a low level,
the cannister must be replaced with a new one
available from Wascomat as Part No. 827601.

Start-up and safety checklist
Before initial start-up of an EX 30 S/EX 50 S
washer, the following safety checks must be
performed:
• 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).
Before the machine is operated, the door safety
interlock must be checked for proper operation
as follows:
• When washer loading door is open, the
machine must not start. Verify this by attemp-
ting to start washer with door open.
• 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
safety interlock or call a qualified serviceman.
If the machine starts with the door open or
the door can be opened after machine is
running, the machine must immediately be
placed OUT OF ORDER and the door
interlock system must be repaired or
replaced. Disconnect electrical power from
the machine until the necessay repairs are
