Connection To The Mains; De-Installation - Rivacold STH009 Manual De Uso Y Mantenimiento

Operation Time
The systems must be set up to run at a maximum of 80% of normal operational time. 100% compressor operation can only occur
under severe load or environmental temperature conditions, outside normal operational limits.
pressure switch
All machines are equipped with a safety HBP pressure switch calibrated to a max. 28bar. The safety LBP pressure switches, are
calibrated according to the gas used and the compressor mode. It is recommended to use the values shown in the following table:
LBP Applicazione MPB
LBP Applicazione LBP
Safety Valves on the Liquid Receiver
The machines under risk category 0, are not fitted with a safety valve.
The machines under risk category ≥1, are fitted with a safety valve.
The risk category of each machine is stated on the identification tag mounted on the machine.

4.3.2. Connection to the mains

The power supply (in terms of voltage and frequency) is provided by the Purchaser and must be sufficient to correctly power the
machine. It is also important to take into account the following:
The power cable must be well tensioned (avoiding twisting and overlapping), not exposed to possible damage or tampering
by children, placed far away from liquid, water or heat, and must be in good condition (when damaged it must be replaced
by qualified.)
Place a suitable differential thermo-switch, between the power cable and the machine, complying with all current legislation
of the country the machine is to be installed; ensuring the line voltage matches the voltage indicated on the tag (see the tag
mounted on the machine); a tolerance of allowed ±10% is allowed of the rated voltage.
ATTENTION:
It is necessary that the size of the power cord is adequate for the power consumption of the machine.
ATTENTION:
Mount the door-switch supplied to the door of the cell: which every time the door is opened turns on the internal light, and
shuts down both the compressor and condenser fans.
ATTENTION:
Mount the cell light to the ceiling of the cell and connect the cable as described in the instructions in the supporting sheet.
Using the LBP range (-15°/-25°C) a cable to connect the door resistor is provided. This connection must be carried out using
a fuse sized according to the resistor used.
ATTENTION:
4.4. Storage
If necessary to store the machine for a period before installation (or following de-installation), we recommend you protect it
adequately and store it in a suitable environment, with the following features:
external surfaces resistant to atmospheric agents;
protected against access to unauthorised people;
with the following environmental conditions:
good ventilation;
room temperature between -20 °C and +50 °C;
relative humidity of compressed air 30% and 80%;
possibly in dry, dust-free atmosphere.
ATTENTION:

4.4.1. De-installation

If the machine must be de-installed, proceed following the inverse order for installation reported in Paragraph 4.3 - Installation.
DANGER:
Gas
R404A -25 °C=1,5 bar
R404A -46 °C=0 bar
the differential thermo-switch must be placed near the machine so that it can be easily seen and
accessed by technicians if maintenance is required.
It is mandatory, according to law, to ensure that the machine is correctly electrically grounded. All
liability is declined if this is not carried out; any liability is declined if the electrical system to which the
plant is connected to is not compliant with all current regulations.
the door-switch cable and any other control cable must be placed far away from the ones powered
with electricity to avoid signal interference.
do not connect the CELL LIGHT and DOOR RESISTOR cables to the 230V line. The labels attached to
each cable shows the connections to be carried out. The maximum power of the light that can be
connected to the cell light cable (included) is 100W for an incandescent lamp and 66W for a neon
lamp (power supply 230V-50Hz). The maximum power of the resistor that can be connected to the
door resistance cable (included with all LBP models) is 300W (power supply 230V-50Hz).
do not remove any packaging possibly present for certain components of the machine and take
adequate precautions to protect the exposed parts.
the manufacturer declines all responsibility for any damage to property and/or persons deriving from
improper interventions conducted by unqualified, untrained or unauthorised staff.
