INSTRUCTIONS FOR THE USER

10
LINEAR
First Section -FOR THE USER
OPERATION BEFORE WORKING
BEFORE STARTING THE WORKING OPERATION BE SURE THAT:
-the wall-mounted on/off switch is switched on;
-the water and steam* cocks are open;
-water and steam (*) are present in the system;
-the filters and the overflow are in their housings;
-curtains are correctly positioned;
-the inspection doors are closed;
-the dimensions of the dishes to be washed do not exceed the washing working
dimensions;
-Check that the detergent and rinse aid containers are not empty.
(*) for steam machines only
DETERGENTS
In case the machine is not provided with an automatic dispenser, pour the detergent
directly into the washing tank and uniformly distribute it on the filters in the doses
indicated by the supplier.
N.B.: If you use chlorinated sanitized detergents, it is always advisable to employ an
automatic dispenser with feeler for the measurement of the detergent
concentration, because brownish spots can appear on the surfaces due to chlorine
reactions when pouring the detergent directly into the tank.
In any case the product shall be introduced near the pump suction pipe into the tank and
at least 15 cm far from the bottom in order to avoid corrosion.
Choice of the suitable cleansing agent is an essential condition if you want to obtain
extremely good washing results as concerns hygienic results. It is then important to
consider some points. First of all only highly alkaline and chlorine-active antifoam
products, especially made for industrial dish-washing machines, must be used and they
must be produced by well known reliable Firms. We provide a short list just as an
indication: Ecolab-Soilax; Henkel; Lever; Diversey; Relativ.
Mean concentration of the powder cleansing agents must be 1,5-2,5 g/lt.
Mean concentration of liquid cleansing agents must be 2-4 g/lt.
In order to avoid scales and corrosions, put cleansing agent above water level on the
nearest area of the sucking pump filter, in this way it will immediately dilute and will not
deposit on the tank bottom.

11
DESCALING
When hard water is used you can find, inside the machine and also on objects,
calcareous sediments which must be removed both for hygienic and operating reasons
by a descaling operation.
Operating process and frequency of this intervention are suggested by your cleansing
agent supplier who has suitable products, generally containing phosphoric acid.
In order to avoid damage to the machine do not increase the quantities and once
operations end rinse abundantly.
HYGIENE
At last each 30 days it would be useful to do this operation which guarantees the
complete hygienic conditions of the machine. We suggest to contact your cleansing
agent supplier who will give you quantity and name of the most suitable product you can
use and that, generally, is an active chloride powder (100-200 ppm).
In order to avoid damage to the machine do not increase the quantities and once
operations end, rinse abundantly.

by means of the wall-mounted switch or by
means of the disconnecting switch located
on the control panel.
WARNING! -Do not disconnect the switch
when the machine is on!
Check and frequently clean the nozzles.
The frequency at which such operation
shall be carried out will be suggested by
the quantity of residues and scales and by
the unsatisfying washing results.
To clean the machine outside and inside,
never make use of corrosive products such
as sodium hypochlorite (bleach) and
hydrochloric acid (muriatic acid), acids in
general, wire wool and steel brushes.
To avoid compromising the correct
operation and to keep the appliance in
optimal hygienic conditions, it is advisable
to carry out periodical sanifications and
scale removing operations.

20
ACHIEVEMENTS
Any deficiency in the washing process is
apparent when dirty residuals are visible.
Any halos might be caused by an
insufficuent rinsing: in this case, check
that the rinsing jets are clean and there is
a sufficient pressure in the water
distribution network (2÷4 bar) ;
In the case that residuals are present,
check that:
• the washing jets are clean
• pre-washing temperatur is 40 °C
maximum;
• washing temperature is from 55 to 60 °C,
• rinsing temperature is from 80 to 85 °C,
• there is detergent in the right
concentration;
• the filters are clean;
• washing water is not dirty;
• the positions of the objects on the
conveyort belt are correct.
SAFETY DEVICES
The belt conveyor dishwashers are
equipped with a number of devices in order
to ensure the safety of the operator and of
the appliance itself.
LIMIT MICROSWITCH
If dishes reach the end of the unloading
area, before the operator has managed to
unload the dishes, the limit switch stops
the belt conveyor motion.
DOOR MICROSWITCHES
Each inspection door is provided with two
safety microswitches forming two
redundant chains (safety level 2).
If one of the doors accidentally opens, the
pumps, the conveyor belt gearmotor and
the rinsing area solenoid valve stop
working.
This way all washing operations are
stopped preventing dangerous jets of hot
water from spurting out.
The operation is restored only when the
doors are closed again and the start button
“H” pressed.
EMERGENCY STOP PUSHBUTTON
Dish inlet and outlet side of the machine is
equipped with a red mushroom-head
pushbutton on yellow field, which, if
pressed, stops all motors. Once the trouble
has been removed, it is possible to restart
the machine only after the pushbutton has
been rotated and released. Subsequently
press the start button “H” again.
TORQUE LIMITER
The belt forwarding feed system is
equipped with a mechanical clutch
coupling joint placed on the feed system.
When an object incorrectly interposes
between the machine and the belt, or the
belt itself is overloaded, the forward
feeding quickly moves to zero.
In this case it is necessary to switch the
machine off by means of stop or
emergency pushbuttons, remove the
obstacle and press the start pushbutton
again.
In order to adjust this safety device, see
paragraph "MAINTENANCE”.
