The washer is designed for being connected to source of compressed air with the pressure of 8-12 bar. Prior to
connecting the washer to a compressed air supply, install the air preparation unit near the washer. The compressed air
connecting installation should be exclusively made of special plastic tubing designed for compressed air. The hose that
connects the washer to compressed air supply should be terminated with quick coupling which, upon disconnecting from
the washer, plays a role of an insulating valve. The hose should be properly dimensioned to avoid unnecessary
pressure drop.
WATER
The washer operates in a closed water circuit, i.e. it does not require permanent connection to the water supply and
drain systems. Therefore, whenever possible, the washer should be installed close to the draining system well.
ELECTRICITY
The washer should be connected to electric power source by a qualified and appropriately licensed electrician. This
person should be properly trained by the washer manufacturer in the area of washer design and operation and know
occupational safety rules in force at the given workshop.
The washer is designed for being connected to three-phase, 400 V, 50 Hz, five-conductor (3L+N+PE) AC network. The
washer motors are protected by own temperature and voltage protecting devices. Prior to connecting the washer to
power supply, check the values of circuit breakers, fuses and possible other protective devices that protect this line. The
power supply network should be equipped with 5-pole (L1, L2, L3, N, PE) connecting socket with current rating of 16
Amps, protected by overcurrent circuit breaker with current rating not less than 20 A and having the “C” class delay
characteristics and additionally protected by 25 A, 30 mA, 4-pole earth fault circuit breaker (due to the motor starting
current and the cross-section area of the line supplying the load that should not be less than 2.5 mm ²). It is also
necessary to check if all conductors of the socket are connected to the proper terminals, i.e. L1, L2, L3, N, and PE
respectively. Such prepared power supply line should never be used for supplying other electric devices.
CHECKING THE MOTORS’ DIRECTION OF ROTATION - TEST START
WHEN INSTALLING THE PLUG PAY ATTENTION TO PROPER DIRECTION OF MOTOR ROTATION, AS
INDICATED BY YELLOW ARROWS ON THE MOTORS.
The purpose of the test start is to verify the direction of rotation of pump and wheel motors as indicated by yellow arrows
placed on the motors. If the direction of rotation is incorrect, the washer will not operate properly. Motors are factory set
for proper direction of rotation, but it is always possible that they will rotate in reverse direction. To check the direction of
rotation, insert the washer plug into power supply socket, then turn the washer on by using main power switch on the
front panel. Check the data displayed on the screen (washing chamber must be closed), then press one of washing time
function buttons and check the direction of rotation for both motors. If motors rotate in the direction opposite to arrows,
immediately turn the washer off by using main power switch, thus disconnecting the machine from power supply source.
Then, to change the direction of motors’ rotation, reverse the two PHASE conductors in machine supply cable plug or in
the supply line socket. Upon reversing the conductors, turn the machine on again and check if motors rotate in the
direction as indicated by arrows, and check all washing times one after the other.
NOTE: REVERSING THE WRONG CONDUCTORS MAY CAUSE DAMAGE TO THE PROGRAMMABLE
CONTROLLER AND ACTUATORS IN THE SWITCHGEAR FROM WHICH THE MACHINE IS SUPPLIED AND
CONSEQUENTLY, QUITE EXPENSIVE REPLACEMENT OF THE ELECTOMECHANICAL COMPONENTS!
