- connect the pipes of the condensing unit to the pipes of the blast chiller
- create a vacuum and then carry out the loading of the refrigerant
- make the electrical connection of the blast chiller to the condensing unit
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)
- in case of incompatibility between the outlet and the plug of the blast chiller, replace the outlet with
another of a suitable type provided that it is in accordance with regulations
- do not insert adapters and/or reductions (Fig. 8)
Fig.8
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 and drawers have not been damaged (cuts or abrasions) and
close with an airtight seal
- check the integrity of the pipes and fittings
