During the recovery and storage of the coolant,
it is essential to observe all rules and regula-
tions locally in force. The rules that allow the
recovering and reconditioning of halogenated
hydrocarbons under optimum quality condi-
tions for the products and of maximum safety
for things, persons and the environment, are
described in the NF E29-795 Standard. Do
not make changes to the unit aimed at add-
ing devices usable for charging, removal and
purging of the coolant or lubricant. All these
devices are provided with the unit.
Refer to the certified dimensions drawings of
the units.
Never reuse the disposable cylinders (i.e.
non-returnable ones), nor attempt to fill them
once empty: When the cylinders are empty, it
is necessary to bleed the residual gas pressure.
Subsequently, they will have to be transported
at the premises used for their recovery. Do not
destroy the cylinders through incineration.
Do not attempt to disassemble fittings, com-
ponents, etc., when the appliance inside is
under pressure or while the appliance itself is
running. Before removing one or more com-
ponents or opening a circuit, make sure that
the pressure inside the unit is 0 kPa and that
the unit has been stopped and de-energised.
Never attempt to overhaul or repair a safety
valve if it appears corroded or shows accumu-
lation of foreign substances, such as rust, dirt,
scale, etc., on the body or mechanisms. Replace
the device, where necessary. Do not install
safety valves in sequence or back pressure.
Attention: no unit component can be used
as walkway, shelf or support. Periodically
check all components and pipes, repairing or
replacing them as soon as the slightest sign of
damage is found.
Do not step on the coolant pipes. Otherwise
they could break causing the coolant to leak
with serious danger to the physical integrity
of persons.
Do not climb on the appliances. Always use a
platform or scaffold.
Use suitable devices (crane, hoists, winches,
etc.) to lift or move heavy components. If the
hand-lifting of a lightweight component can
also compromise the operator’s balance, it is
best to perform such lifting using a mechani-
cal device.
To replace or repair the components, use only
original spare parts having the part number
specified in the list of recommended spare
parts.
Do not purge the hydraulic circuits containing
industrial brine, without having first informed
the technical assistance department at the
installation site or a competent body.
Before intervening on the components in-
stalled inside the circuit (net filter, pump,
water flow switch, etc.), it is necessary to close
the shut-off valves at the water inlet and outlet,
and purge the hydronic unit circuit.
Periodically inspect all valves, connections
and pipes of the hydraulic circuit and of the
cooling circuit to ensure there is no trace of
corrosion or leaks.
We recommend wearing protective ear muffs
when performing work near the appliance and
it is working.
Before loading the unit, make sure to have
chosen the correct coolant.
Loading coolants different to the original
charge type (R-410A) will compromise the
machine operation and might even cause
irreparable damage to the compressors. The
compressors work with R-410A and are loaded
with asymptotic polyester oil.
Before any intervention on the cooling circuit,
the coolant charge must be recovered in full.
1.3 PRELIMINARY CHECKS.
Check the received appliances:
• Inspect the unit in order to detect any damage
or ensure that there are no missing parts. If a
damage is found, or in case of incomplete sup-
ply, promptly file a complaint with the shipping
company.
• Check that the unit received matches that
ordered. Check that the data on the unit iden-
tification plate match the order and the delivery
note.
• The identification plate is fixed on two different
points of the unit:
- outside one of the two sides of the unit
- inside.
• The unit identification plate must bear the fol-
lowing information:
- Model number - dimensions.
- CE Marking.
- Serial number:
- Year of manufacture, static test and seal test
dates.
- Fluid carried.
- Coolant used.
- Coolant charge for each circuit.
- PS: Min./max. pressure allowed (low pressure
side and high pressure side).
- TS: Min./max. temperature allowed (low
pressure side and high pressure side).
- Switch-off pressure.
- Unit leak test pressure.
- Voltage, frequency, number of phases.
- Maximum current absorbed.
- Maximum inlet power supply.
- Unit net weight.
• Make sure that all options ordered for on-site
installation have been delivered and are not
damaged.
The unit must be subjected to periodic checks,
if necessary removing the thermal and acoustic
insulation along its entire life cycle in order
to check that no impact caused by tools or
other may have damaged it. Any damaged part
must be immediately repaired or replaced, as
appropriate. See also Chap. 5. “Maintenance”.
