STARTUP:
•
At this time, the machine should in position and connected to power and mains
water. Be sure the large drain hoses are down the drain facility pipe for a distance
of say 30 cm. Be sure there are no loops, kinks or obstructions in these large
hoses. The drain water should “fall” down the hoses directly into the drain.
NOTE: for the bench style machine, the drain hoses can be placed into a sink close
by, but if the hoses can be passed into a drain pipe that is lower than a sink, the
bath will drain much faster.
•
To remove the bath lid,
push the lid horizontally towards the rear and lift the front
edge past the retainer pips. Be sure there are no loose parts or packing materials in
the bath and be sure the mesh strainer is inserted into the drain hole in the bath and
is lying flat on the bath bottom. Earlier models have a mesh plate or a corrugated
plate that must lie flat in the bath to allow the bath water to circulate under the
beakers. Later models have small individual supports for the beakers.
•
In the bath, observe the temperature sensor, the 2x level switches, the circulation
pump and the overflow upstand pipe.
•
For floor mounting units, lift the cover from the d/w tank and remove it to permit
visual access. Observe the temperature sensor, upper and lower level switches,
the pump plus the heat exchanger cooling coil mounted towards the front.
•
If the ‘U’ shaped bracket is not yet fitted to the cover, with fingers, remove the small
‘dress plug’ from the socket that is preferred for the mounting the control housing.
Place the bracket over the hole and insert the blue headed screw provided to fix the
bracket to the cover. Tighten firmly.
•
Be sure mains power is off at the isolation switch on the wall. Lift and remove the
long cover and turn ON all circuit breakers that control the heater and control
circuit(s). Refer to the hardware layout drawing if necessary. Replace the cover,
turn ON mains power to the machine.
•
Position the control unit into the ‘U’ shaped mounting bracket and gently tighten the
blue knobs to clamp it into position. Twist and tilt it until it suits your viewing angle.
At the rear, connect the multi pin plug and tighten the 2x security screws. The floor
models use two cables to connect to the control unit. Note the small rocker switch
on the front of the control unit. When switched towards the green indicator it is ON.
Note:
The large diameter
overflow pipe is adjustable up
and down. If the bath must
be completely drained empty,
it can be removed completely
by twisting and pulling it
upwards from inside the bath,
but normally, the overflow
pipe is set to be about 3mm
higher than the upper level
switch level of water in the
bath. A lockable collar fitted
to the overflow pipe ensures
the pipe cannot be inserted
lower than the correct level.
