Drainage connection
Conveyor belt dishwashers require effective drainage as they run continuously. The machine drainage hose
must be connected to the drain so that water flows freely under gravity; therefore, the drain must be lower than
the drainage hose (
Fig. 8)
.
Always use pipes able to withstand a constant temperature of 70ºC. The machine drainage hose must be
connected to a sump with a drain trap to prevent the return of bad odours.
Check that the drainage system operates correctly and is not blocked.
4.7
Dispensers (detergent/rinse aid)
The appliance does not have detergent and rinse aid dispensers, but is designed to permit the installation of
external dispensers.
To complete this installation, the dishwasher must be switched off at the mains using the disconnection switch
and the mains switch, and the water inlet tap closed.
The following installation and adjustment must be carried out by authorised and
qualified personnel.
Contact a qualified chemical product supplier to determine the most suitable product
and dose in order to optimise the wash.
The guarantee does not cover damage caused by the incorrect installation or use of
dispensers and chemical products.
The correct selection and dosing of detergent and rinse aid is essential for obtaining an optimum wash.
Only
use liquid or solid detergent specially designed for use with industrial dishwashers and which is non-
foaming at high temperatures.
Detergents designed for domestic use should not be used under any
circumstances.
The results of the wash should be assessed after two fills and at least three wash cycles in order to stabilise
the doses. There should not be any foam in the tub after running the cycles.
Scratched dishes and the formation of foam in the wash solution are usually an indication of excess rinse aid.
Dishes with too many water drops or which are slow to dry are usually a sign of insufficient rinse aid.
4.7.1
Dispenser hydraulic connection
For the hydraulic connection of the dispensers, remove the lower
front panel of the appliance.
First remove the panel fastening bolts and lift the door.
Turn the front panel slightly upwards at the lower part and then
remove.
The rinse aid / detergent dispenser hoses can be inserted through
the two packing glands located in the lower central part of the
machine.
4.7.1.1
Detergent dispenser
The detergent entry point to the wash tub is in the upper part of
the front of the tub and is identified by a label.
There is a covered hole just next to this, and a packing gland
should be installed here for the detergent dispenser.
A stainless-steel packing gland should be used, as detergent is
an abrasive product and plastic packing glands wear faster.
