INSTALLER SECTION

WARNINGS:

Once installation is complete, it is recommended to detach the installer’s guide section of 
this manual for future reference

.

1. MACHINE INSTALLATION

1.1 Receiving product

After removing the packaging, make sure that the apparatus was not damaged during tran-
sportation. If this should be the case, notify the seller of the defect. For packaging disposal 
see chap. 9.

1.2 Water connection

Connect the machine water supply with a stop valve that can quickly and completely 

turn off water flow.

Make sure that the water supply system is within the parameters reported in tab. 1.
If the water system pressure is above 4 BARS (400 KPa), a pressure reducer is recom-
mended.

It  is  compulsory  to  install  a  water-softner  for  water  with  average  hardness  above 
10°f.

Dishes/objects will be cleaner and the machine will last longer. 
Each machine is supplied with a rubber water load tube with a 3/4"F threaded connection. 

It is recommended to connect the tube to water supply systems that do not exceed 55°C, 

if connected to hot water. 
Connect the supplied machine draining tube to the connector located under the tank, making 

sure that the water flows freely (giving, therefore, minimum slope). 

The drain tube shall always be connected to a siphon (Ø) in order to prevent the release of 
odours.

 

The MAXIMUM drain permitted height is 10cm.

1.3 Electrical connection

The electrical connection shall be carried out in accordance to the laws in force. 
Make sure that the line voltage is the same as that written on the machine plate

Apply a 

suitable magneto-thermic omni polar switch measured in accordance to absorption 
and that is equipped with a contact opening of at least 3 mm (always turn the machine 
off with this switch). This is the only switch which guarantees total electric supply 
system isolation.

This switch shall be solely and exclusively used for this purpose and installed in the imme

-

diate vicinity

.

Make sure that the facility is equipped with efficient grounding

.

Moreover, the machine has a clamp at the back indicated by the symbol (see fig. 1) that is 

used for equipotent connection among different apparatuses. The maximum power expresses 

in watts (W) and amperes (A) is located on the serial number plate for line measurement, 
cable and switches

.

N.B.: 

for machines cable types H05RN-F or H07RN-F must be used or replace with 

others which correspond to the regulations of the country where the ware-washer is 
installed. A 4mm² section for voltage 380-415V3~, and a 6mm² section for voltage 
220-240V3~.

 

The replacement of the cable must be carried out by specialized 

personnel only.

The seller/importer/installer must adapt the supply cable isolation class in function to the 
work environment respecting the Technical Regulations in force
