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.
2 ELECTRICAL CONNECTION AND EARTHING
2.1 ELECTRICAL POWER SUPPLY
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. 73.
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. 31).
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 “APPENDICE - 2” Pag. 70).
•
Verify the supply tension at the socket, it must be b/- 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 power supply cable section is adequate to the unit power consumption.
•
The law requires that the unit is earthed; therefore it is necessary to connect it to an
efficient earth connection. In order to prevent any risks
If the power supply cable is
damaged, it must be substituted by the manufacturer or by its technical assi-
stance service
. Installation must be carried out only by qualified technicians according to
the regulation in force. No liability whatsoever can be accepted if the above instructions
in not complied with.
•
Nel caso in cui il compressore sia danneggiato,
questo deve essere sostituito esclusivamente da perso-
nale specializzato in modo da prevenire ogni rischio. Si consiglia, per evitare in caso di guasto di disinserire tutto
l’impianto, di utilizzare come sezionatore un interruttore magnetotermico con differenziale da alta sensibilità.
