pressure requirement 100 to 400 kPa to connection point.
3. Electrical Connection: Electrical connection should be made in
accordance with rating plate at side of control box and in
accordance with local electrical authority regulations. An
isolating switch should be mounted on wall near machine.

I NSTALLER - INITIAL START UP PROCEDURE
4.
1. Open front inspection door, check no foreign matter has been
left inside of machine.
2. Check that the overflow tube is sitting within the drain hole at
the bottom of the tank by removing one of the strainer pans
beside the drain lift handle at the centre of tank. Check that all
strainer pans are seating properly on the tank shelf.
3. Check that all curtains are in position as per diagram (see
page 11) note position per curtain length.
4. Close inspection door. Turn on hot water supply valve. Switch
on power supply isolator then turn rotary switch on the control
panel to “fill” position. The green fill indicator light will glow till
fill is complete and stops automatically. Open inspection door,
check level of water in wash tank by lifting a strainer pan (level
approx. ¾ of tank height) refit strainer and close inspection
door.
5. IMPORTANT Before putting machine into operation, check
direction of rotation of all motors as per the arrow on the motor
cover, if they are rotating in the wrong direction, change over 2
phases on the power supply.
6. Turn rotary switch to position (“HI. SP.” or “LO SP.”-The
ES-100 has only one speed and will work in either position)
to put machine in washing mode. Push the green start button
and the machine will start. Check during operation that the
wash thermometer is showing 60-65°C and the final rinse
82°-90°C. The rinse will function automatically as the racks
pass the trip lever. All thermostats are factory set and should
not need to be adjusted.
At this point th machin is r ady to comm nc washing.
(NOTE: If the machine conveyor drive does not operate and
the amber light “ AIT-LO TEMP.” is illuminated, the rinse is
not at correct temperature, consult temperature gauge, wait for
correct temperature and check conveyor drive is now
operating.(Amber light will no longer be illuminated)

Final Rinse 82-90
O
C
6. Periodically check the strainer pans and empty the contents if
necessary into a rubbish bin. Rinse the strainers under a tap

S HUTDOWN AND MAINTENANCE
7.
1. hen washing is complete turn the rotary switch "OFF".
2. Open the wash chamber inspection door, lift the overflow tube
handle and tilt the overflow tube to one side to drain tank.
3. Remove curtains and wash with warm water, then allow to air
dry.
4. Check that wash arm jets are free from foreign matter. To
clean remove the end caps, make sure the strainers are fitted
and the tank is full. Close door turn on machine press the
green start button then turn off. Repeat this process when jets
are clean replace the end caps.
5. Remove the strainer pans and clean them under a tap.
Occasionally hose the inside of the machine to keep it clean
and make sure to drain all the water out of the tank.
6. Check rinse arms for foreign matter.(may need cleaning if
