assistance. If in doubt, consult the manufacturer’s technical after-sales service.
The plants that use inflammable refrigerants must be subjected to the following verifications:
• the dimension of the load must be compliant with the chamber in which the components
containing the refrigerant are installed;
• the plants and ventilation outlets must operate adequately and not be obstructed;
• if an indirect refrigeration circuit is in use, check the presence of refrigerant in the secondary
circuit; the marking on the systems must be visible and legible;
• illegible markings and signs must be corrected;
• the pipe or refrigeration components must be installed in a position where it is improbable
that they are exposed to substances that could corrode the components containing the
refrigerant, unless the components are manufactured with intrinsically corrosion resistant
materials or are appropriately protected from corrosive agents.
i. Check the electric devices
The repair and maintenance interventions of electric components must envision initial safety
checks and component inspection procedures.
In the case of a fault which may compromise safety, no electric power supply must be connected
to the circuit until it has been suitably repaired.
If the fault cannot be repaired immediately, but the operation must be continued, use a suitable
temporary solution.
This solution must be communicated to the owner of the plant so that all parties can be informed.
The initial safety controls envision:
• draining the condensers: this operation must be performed safely to prevent the possible
formation of sparks;
• no exposure of components and electric wiring to voltages during loading, repair or purifi -
cation of the system;
• the continuity of the earth.
l. Repair interventions of the hermetic components
• During the repair of hermetic components, all electric power supply lines must be discon-
nected from the appliance running, before the eventual removal of the hermetic covers, etc.
Whenever it is absolutely necessary to have electric power supply for the unit during main-
tenance, a constantly active leak detector must be positioned in the most critical point in
order to signal a potentially dangerous situation.
• Particular attention must be paid to the following to guarantee that, in the case of intervention
on electric components, the housing is not altered in a way to affect the level of protection.
This includes damage to cables, excessive number of connections, terminals not manufac-
tured in compliance with original specifications, damage to the gaskets, incorrect installation
of the closing devices, etc.
• Make sure that the appliances are mounted securely.
• Make sure that the gaskets or sealing materials have not deteriorated to the point that they
cannot be used to prevent the entry of inflammable atmospheres. The spare components
must be compliant with manufacturer specifications.
The use of silicone-based sealants can inhibit the efficacy of some types of leak detection
equipment. Intrinsically safe components do not have to be isolated before working on
them.
2.3 - DATA TABLE
To obtain optimal performances, use the unit within the temperature intervals indicated below.
If the unit is used outside these intervals, it is possible that some protection functions intervene, causing
improper operation.
