Installation
Machine foundation
The machines are designed to be bolted in
position to a concrete floor or specially prepared
concrete foundation. A template showing the size
of the foundation and positioning of the
foundation bolts can be provided by Wascomat.
For installation on an existing concrete floor, the
floor must be at least 8" thick and of good quality.
If the floor does not meet these requirements,
then a 6-8" high concrete foundation should be
made. A prefabricated steel base is available for
mounting of machines without an additional
foundation.
Follow the instructions below when making a
concrete foundation:
1. Decide where to place the machine and
consider maintenance requirements, i.e.
determine a suitable distance from the rear of
the foundation to the wall, and the distance
from the foundation to the nearest side wall.
The distance should be at least 16 and 12
inches, respectively.
2. Break up the floor to a depth of 3 inches,
making sure that the sides of the hole slope
inwards - the bottom of the hole should be 5
inches longer than the upper length.
3. Wet the hole well. Brush the bottom and sides
with cement grout.
4. Prepare a casing and fill with 3,000 PSI min.
concrete to form foundation. Make sure the
foundation is level.
5. Use the template to position the foundation
bolts correctly - bolts are to extend 1 1/2"
above concrete.
NOTE: A prefabricated steel frame, designed
to be placed in the concrete instead of the
individual mounting bolts, is available.

Mechanical installation
• Before mounting the machine place wide steel
shims on the concrete foundation over the
bolts.
• Lift the machine and lower it in position. Never
use the door or the door handle to lift or lower
the machine since this can damage the door
and door interlock.
• Check that the machine is level front-to-rear
and side-to-side and standing firmly on the six
supporting points. Spacing washers must be
mounted if one or more of these points is not
resting against the floor/foundation.
• Place flat washers over the foundation bolts
and secure the machine in position by tighte-
ning the self-locking nuts. See illustration 7
below.
• Check and tighten the nuts every week for the
first month to compensate for any setting of
the foundation.
NOTE
If the side panels of the washer vibrate
during extraction remove the shipping
security which connects the top of the
cylinder to the upper section of the back
panel. This is used to prevent shipping
damage but has no function after the
machine is installed.

Electrical installation
All electrical installations are to be carried
out by licensed personnel.
Although the machines are fitted with a thermal
overload in the motor windings a separate three-
phase common-trip 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.
Use inverse-time circuit breaker only.
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.
After installation, do the following for 3-phase
machines:
Check the incoming power for a high voltage or
"stinger" leg. If present, connect that line to L2 on
the terminal block.
Start the machine and check that the drum
rotates in the proper direction during extraction,
i.e. counter-clockwise when seen from the front.
If the drum rotates in the wrong direction inter-
charge line L1 and L3 at the power connection
terminal.
Check that the jumper clips on the transformer on
the control unit are correctly connected in relation
to the incoming voltage. The different alternatives
are printed on the transformer circuit board.

Water connection
NOTE
All plumbing must conform to national
and local plumbing codes.
Incoming water lines do not require non-return or
back-suction valves, as the machine is already
fitted with a siphon breaker. However, all inco-
ming lines must be fitted with shut-off valves.
• Water inlets are labelled for hot and cold
water connection.
• Before connecting the water hoses flush the
water system thoroughly and check that the
filter at the machine inlet is fitted correctly.
This is essential since dirt and grit in the water
lines may clog the inlet valve filter screens
and/or the drain pilot valve. This could cause
the machine to fill very slowly or the drain
valve not operate properly.
• Connect the machine to the water mains with
3/4" reinforced rubber hosing not to exceed 6
ft in length. Hang the hosing in a large loop.
Do not use rigid piping.
Never force a hose onto the threads or you may
cause cross-threading and leaks. If this occurs,
place the threaded portion of the hose over the
valve threads and push forward firmly, to catch
the next thread. Then tighten.

Drain connection
Connect a 3" (75 mm) flexible hose to the drain
outlet of the machine.
The drain hose must not have sharp bends and
must slope from the machine to assure proper
drainage.
If the machine drains into an open trough, the
trough should have a minimum slope of 1/8-inch
to 1/4-inch per foot towards the main drain.
Do not reduce the size of the drain connection
from the machine to the waste line.
NOTE
To simplify installation, Wascomat has
made available the following hose kits:
For S28/125 – part. No. 002008
For S28/185 – part. No. 002009
These kits contain inlet hoses, drain hose,
hose clamps and washers.
Start-up and safety checklist
Before initial start-up of a Wascomat washer-
extractor, the following safety checks must be
performed:
• Make sure the machine is properly bolted to
the floor.
• 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.
