Introduction
Introduction
The EX 7 and EX 10 Emerald models washer/extractor with high spin
speeds, have been developed to meet the needs of state-of-the-art profes-
sional laundromats, institutions, hospitals etc., where high quality auto-
matic washing and quick formula variation are required.
Emerald models are unique because you can program different prices for
the seven wash cycles, giving the customer a real choice and allowing you
to maximize revenue by changing what each cycle is worth. In addition, you
can charge a higher price if the customer selects the Extra Extract option.
Using an external clock and wiring harness, these models may be pro-
grammed to lower the price by any percentage between any hours of any
days, for the ultimate in pricing flexibility!
The machines are free-standing, i.e. the drum is free to move relative to the
frame of the machine, being suspended from it by springs. This results in a
considerable reduction in vibration transferred to the frame of the machine,
which in turn simplifies installation: no special foundation is required.
The seven cycles offer different water temperatures, wash times, extraction
times, and normal or gentle drum rotation. EMERALD SERIES washers
achieve maximum environmental efficiency because only the minimum
amount of water is used for each cycle, which vary in duration.
When ordering spare parts or contacting Wascomat or your dealer for
service, always give the machine serial number, model, voltage and other
electrical characteristics appearing on the data plate at the top left of the
rear panel of the machine. The serial number is also printed on a sticker
inside the door...

Installation
The machines are free-standing, i.e. the drum
can move relative to the frame of the machine.
This results in a considerable reduction in vibra-
tion transferred to the frame which in turn
simplifies installation: no special foundation is
required.
The machine is delivered complete with expan-
sion bolts, template etc. packed inside the drum.
Move the machine on its pallet to where it is to be
installed before removing the pallet retaining
bolts.
Location
Install the machine close to a floor drain or open
drain.
In order to make installation and servicing the
machine easier the following clearances are
recommended:
• At least 20" between the machine and the wall
behind
• and a minimum of 2" on both sides of the
machine whether installed next to the wall or
other machines.
Where space is limited it is possible to reduce
this distance to a minimum of 1" at the rear and
sides, since most service operations are carried
out from the front or top of the machine.
FloorThe floor must be able to withstand the following
loads:

Installation
Mechanical installation
The machine is delivered with the drum locked in
place by four transport bolts fitted between the
frame and the drum. In orderto remove these
and install the machine, proceed as follows:
• Unpack the machine.
• Slacken off the screws in the lower edge of
the front cover plate and remove the plate by
pulling downward and outward to unhook it
from the chassis.
• Unscrew the retaining screws on the rear
plate and remove the plate. Remove the
drainage connection by unscrewing the two
screws. Lift the drainage connection upwards
until comes loose from the rear plate.
• Mark and drill two holes (diameter =5/16")
about 4" deep in the positions shown.
• Remove the machine from the transport pallet.
Fit the adjustable feet provided.
• Place the machine above the bolt holes you
just drilled. Always lift the machine by the
chassis, never by the door or door handle.
• Remove the four transport bolts securing the
drum to the chassis.
• Check that the machine is level and steady.
Adjust the level by using the four adjustable
feet (check first that they are screwed in as far
as possible). Lock the feet using the lock nuts
when the machine is satisfactorily positioned.
NOTE!
It is of utmost importance that the
machine be level, from side- to- side as
well as front- to- rear. If the machine is not
properly leveled, it may result in a false
out-of-balance cutout.
• Insert the expansion bolts supplied in the
holes drilled in the floor.
Fit the washers and nuts, and tighten well.
After the machine has been in use for a while
check and retighten the nuts if necessary.

Start-up and safety checklist
Before initial start-up of a Wascomat washer-
extractor, 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

Insert required number of quarters as shown
on the display, which counts down quarters as
they are inserted. Press START button when
the display shows 00.
A clock symbol will now appear and remaining
wash time in minutes counts down. (The time for
each cycle will not be displayed until the cycle
has been run once completely from beginning to
end, so the microprocessor knows how long it
should take). The microprocessor retains in
memory how long it took to run each cycle the
last five times and displays the average time.
Since water pressure may fluctuate affecting fill
times, the displayed average cycle time is not
always exact and may vary from machine to
machine. If you find cycle times taking longer and
longer, use that information as a warning that
your water inlet screens may be clogged,
extending fill times, or some other problem may
exist.

Rapid Advance
Within 5 minutes after starting (only while the
colon : is flashing), steps of the wash cycle can
be skipped by using Rapid Advance.
• Press and hold down the START button until
the arrows rapid advance. Stop pressing
where you want the cycle to continue.
• If during the first five minutes of a cycle
customers realize that they put a wrong item
of clothing in the washer (for example a
brightly colored shirt mixed up with white
sheets), they can rapid advance through the
entire cycle, open the door and remove the
item. Then lock the door and press START
again to continue the cycle from where rapid
advance was started. No money is lost and no
extra time is gained. The remaining time will
not be displayed.
Changing Wash Programs While Washing
If within 5 minutes after starting a cycle (only
while the colon : is flashing) customers realize
that the wrong cycle has been selected, they can
push the START button once briefly to put the
washer on pause. They may then press a
different wash cycle button and press START
again to continue from the same step in the new
cycle.
If the customer selects a different cycle or Extra
Extract option that costs more money, the
washer will not start again unless additional coins
are inserted as shown on the Information
Display. There is no way for a customer to pay
for a less expensive program and switch to a
more expensive program without paying for it, or
to gain additional free wash time.
Note: Rapid Advance is only possible during the
first five minutes of a cycle, while the colon : is
flashing. However, if the START button is
pressed after five minutes has elapsed it will put
the wash cycle on pause, which means washing
stops, the clock stops counting down remaining
wash time, and an arrow flashes on the
Information Display at which ever step the wash
cycle was in when pause began. Press START
again to resume washing. Be alert to any
accidental pauses, which are unlikely but
possible.
