CHAPTER 15 ELECTRICAL WIRING AND CONNECTIONS
The electrical system and connection must be carried out by qualified personnel. Before installation,
measure the impedance of the network, the impedance value for the connection to the network must
not exceed 0.075 ohm.
For safety reasons you must follow these guidelines:
- verify that the sizing of the electrical system is suitable for the power consumption of the blast chiller
and that it provides for a differential switch (circuit breaker)
- All the chillers are supplied to no electrical plug (Figure 8), for connection to carefully observe what
described on the label on the electrical connection cable (5)

The power cord has the connection type “Y” and it can be replaced exclusively by the
manufacturer or authorized technical service
It is essential to correctly connect the blast chiller to an efficient earthing system carried out
as specified by the applicable provisions of law.
CHAPTER 16 INSTALLATION OPERATIONS
It is important, in order to prevent errors and accidents, to perform a series of checks before starting
up the blast chiller in order to identify any damage incurred during transport, handling and connection.
Checks to be performed:
- check the integrity of the power cord (it must not have suffered abrasions or cuts)
- check the solidity of the legs, door hinges, shelf supports
- check the integrity of the internal and external parts (pipes, heating elements, fans, electrical
components, etc.) and their fixing
- check that the seals of the doors have not been damaged (cuts or abrasions) and close with an
airtight seal
- check the integrity of the pipes and fittings
CHAPTER 17 REINSTALLATION
It is necessary to comply with the following procedure:
- disconnect the power cord from the power outlet
- the handling should be carried out as described in chapter 14
- for a new placement and connection, please refer to par. 14.1
- proceed to the possible recovery of the refrigerant gas in accordance with the regulations in force
in your country
