GB
(fig.1)
• If the equipment are not level, it is possi­ble that their functioning and the flow of condensate will be compromised.
AVOID
• Places exposed to direct sunlight
• Closed, hot places with little air change
• Do not install the machine near any heat source (fig.4).
2.3 Room temperature and air change
For air-cooled refrigeration groups, the air temperature in the operating environ­ment must not exceed 32°C. The declared performance ratings are not guaranteed over this temperature. The machine can function safely up to 38°C. Remote condensing units must be installed in special rooms or outside in a place not exposed to direct sunlight; if the circumstances make it necessary, the installer must assess whether to use a cover or special roofing (the costs will be met by the purchaser). In any case, a sufficient air change must be guaranteed.
2.4 Connection to the electricity mains.
Upline from every piece of equipment it is essential to install a thermomagnetic dif­ferential switch in accordance with the regulations currently in force in the coun­try or installation, complete with knife switch.
• The electrical cables for connection must comply with the characteristics shown in the technical data (see the machine’s wiring diagrams, to be done by the instal­lation engineer)
The grounding wire must be correctly connected to an efficient grounding sys­tem.
THE MANUFACTURER DECLINES ALL LIABILITY AND ALL WARRANTY OBLIGATIONS IF DAMAGE TO THE EQUIPMENT, INJURY TO PERSONS OR DAMAGE TO PROPERTY RESULTS FROM INCORRECT INSTAL­LATION AND/OR INSTALLATION THAT DOES NOT COMPLY WITH LOCAL REGULATIONS.

2.5 Notes for the installation engineer
Check the proper installation and system
testing before commissioning the machine (test report).
1.Check any gas leaks from the welding or joints made during the installation phase.
2.Check the good insulation of the connec­tion pipes linking the condenser and the remote condensing units.
3.Check the electrical connection.
4.Check the electrical input values.
5.Check the standard pressure of the refrigeration plant.
6.Verify the plumbing connection with the regulation of the pressure switch valve during operation and the good circulation of the condensate water (water-cooled assemblies).
7.Check that the conservator reaches the set temperature and perform a manual defrosting. If the equipment or the remote condens­ing unit are not moved into position verti­cally (e.g. on their backs) or they have been overturned during installation, do not turn on immediately but wait at least four hours before operating.
• Inform the customer how the equipment should be used exactly with specific ref­erence to the use and the requirements of the said customer. The installation
and the commissioning must be done by persons authorised by Castelmac.
2.6 Safety and control systems
• Door microswitch: this shuts down fan operation in the cell when the door is open.
• General protection fuses : these protect the full power circuit from short circuits and any overloads.
• Safety thermostat: This cuts in in the case of overtempera­ture due to long operating times of the evaporator defrosting heating elements.
• Safety pressure switch: this cuts in in the case overpressure in the refrigerating circuit
• Door opening from inside if it accidental­ly shuts
• Chamber temperature check: this is managed by the electronic card through the sensor inside the cell• Temperature check at the end of defrost­ing: this is managed by the electronic card through the sensor on the evaporator.

7.2 CONDENSER CLEANING
For the correct and efficient functioning of the condenser, it is necessary for the air condenser to be kept clean to allow the free circulation of the air.

You are advised to use a vacuum clean­er in order not to spread removed dust around the environment. If there are greasy deposits, eliminate them with a paint brush soaked in alcohol.
DO NOT SCRAPE THE SURFACES WITH POINTED OR ABRASIVE BODIES.
