1.8 BLAST CHILLER WITH BUILT IN CONDENSING UNIT

The blast chiller is provided with built in condensing unit, therefore it is necessary not to obstruct the blast

chiller/freezer air inlet corresponding to the front grid for the air extraction in order to allow a proper air

circulation. Keep clear the whole blast chiller/freezer perimeter.

We remind you that room temperature rises or insufficient quantity of air to the unit condenser, reduce the

blast chiller performances with possible deterioration of the products and more energy consumption. If the

blast chiller/freezer with built in condensing unit was leant on the side during transportation we suggest you to

keep the product in upright position for at least 8 hours, before switching it on. In this way, you will allow the oil

to flow in all the components, lubricating them again. Afterwards you can proceed with the starting.

1.9 BLAST CHILLER WITH REMOTE CONDENSING UNIT

For what concerns the electric connection, it is necessary to follow meticulously the electrical

rules in force. We remind you that all the operations must be performed by qualified staff only.

The remote condensing unit must be placed far from atmospheric agents, avoiding using the

room where it is installed for storing goods, in order to assure air circulation.

According with the remote condensing unit characteristics, it is necessary to respect the space

from the wall and other obstacles, to ensure always and adequate circulation of air which grants

the correct functioning of the item and an easy maintenance.

2 ELECTRICAL CONNECTION AND EARTHING

The installation and the electrical connections must be carried out in conformity with the elec-

trical rules in force. These operations must be carried out by qualified staff. The company declines

any responsibilities originated from the no observance of the above rules in force.

See the blast chiller electric diagrams at "APPENDICE - 5" Pag. 140.

Before plugging in the blast chiller, it is necessary to proceed with its complete and careful cleaning, using warm

water with no aggressive detergents and drying with a soft cloth all the humid parts (read with attention the

chapter "3 CLEANING" Pag. 32 regarding the blast chiller cleaning).

In order to carry out a correct plug in you must proceed as follow:

Prearrange a thermal magnetic circuit breaker switch and be sure that the frequency/tension of the line

corresponds to that shown on the blast chiller serial number label (see the label placing "APPENDICE - 1" Pag. 134).

Verify the supply tension at the socket, it must be between +/- 10% when you start the compressor.

We recommend you to install a bipolar-switch (or 4 square pole switch) with contact opening of at

least 3 mm, at the head of the socket. This switch is obligatory if the loading is over 1000 W or when the blast

chiller is connected directly without the use of the plug. The mag thermic switch has to be placed nearby the

blast chiller in order to be well seen by the technician in case of maintenance.

It is necessary that the connection cable section is commensurate to the power consumption of the unit.

The law requires that the unit is earthed; therefore it is necessary to connect it to an efficient earth connection.
