Demolition And Disposal - Rivacold STH009 Manual De Uso Y Mantenimiento

UK
1. Isolate the machine from electrical power.
2. Refer to the Paragraph 4.4.1 – De-installation in Chapter 4 – Transport and Installation, proceed to de-install the machine;
also contact the manufacturer's Technical Office to obtain the necessary support during this intervention.
3. To proceed to moving the machine components, work according to the instructions reported in Paragraph 4.2 – Transport
and Movement in Chapter 4 – Transport and Installation.
4. Organise the components adequately based on the fact they have to be transported to another location (refer to Paragraph
4.2 – Transport and Movement in Chapter 4 – Transport and Installation), which must be stored (refer to Paragraph 4.4 -
Storage in Chapter 4 – Transport and Installation) or demolished (refer to Paragraph 6.4.3 – Demolition and disposal).
DANGER:
6.4.3.

Demolition and disposal

When the machine has reached the end of its lifecycle, before proceeding to final disposal, it is necessary to perform a series of
operations to minimise environmental impact linked to the disposal of the machine components, as requested by the norms in
force on waste disposal.
These operations are:
1. Separate and store the parts with environmental impact, or rather:
a. separate the various parts that could cause pollution;
b. select the materials to encourage their recycling, dividing them for differentiated disposal (in particular select the plastic
or rubber elements).
2. The gas contained in this system must not be dispersed in the environment. Thermal insulation of the buffer and oil in the
compressor must undergo differentiated collection; for this reason, we recommend you dispose of the generator only in
specialist collection centres and not as normal iron scrap, following the norm directives in force.
3. Dispose of the casing, or rather:
a. having removed and stored the polluting elements, entrust disposal of the casing to specialist structures.

On request it is possible to fit the following options:
GAS R134A
As an alternative to the standard R404A the machine can be designed to use a different refrigerant gas, identifiable by the
machine code (written on the identification EC tag place on the machine ): Y=R134a.
WATER CONDENSATION
By replacing the air condenser with a water one.
To connect the water condenser pipes having a diameter not lesser than the ones placed on Blocksystem ST-SP are required,
while at the same time taking into account the inlet and outlet specifications. The inlet pipe is distinguishable by a barostatic valve
located on it to adjust the water flow. Install the water supply stopcock within easy reach of the operator.
ATTENTION:
To improve machine lifetime and performance ensure that:
the water temperature is between 20 and 30°C for the units with tower water condensation and between 5 and 20°C for the
units with well water condensation;
the water pressure is between 1 and 5 bar.
ATTENTION:
CONDENSATION CONTROL BY PRESSURE SWITCH
(optional when not supplied as standard)
stops the condenser fan when the condensing pressure falls below the set point minus the differential.
CONDENSATION CONTROL BY FAN SPEED CONTROLLER
(optional when not supplied as standard)
adjusts the speed of the condenser fan according to the condensation pressure, in order to stay within the set limits. It is connected
to the high pressure circuit. The instructions for use are attached to the documentation of the machine.
MINIMUM PRESSURE SWITCH
It stops the machine when the pressure of the suction circuit falls below the set value minus the differential. This happens as a
result of a serious failure.
THERMOSTATIC EXPANSION VALVE (when not supplied as standard)
If there is a particular type of thermo-static valve the refrigeration system is equipped with a liquid receiver and a thermo-static
valve after the condenser.
the manufacturer declines all responsibility for any damage to property and/or persons deriving from
improper interventions conducted by unqualified, untrained, inadequately equipped or unauthorised
staff.
on demolishing the machine, ensure the identification plate of the machine and the relevant technical
documentation can no longer be used.
It is the faculty of the client to return these elements to the manufacturer's Technical Office for their
destruction.
Simple conservation in an inaccessible location of the aforementioned elements is not permitted.
On completion of the interventions, communicate to the manufacturer's Technical Office that the
machine has been disposed of.
never close the stopcock when the machine is running.
water pipes must be protected from low external temperatures.
