DC-C 2. SAFETY The lubricant used is polyester oil. Please refer to the information provided on the compressor data plate. For further information regarding the characteristics of the refrigerant and oil used, refer to the safety data sheets available from the refrigerant and oil manufacturers. Main Ecological Information Regarding the Types of refrigerants Fluids used.
DC-C 2.5.1 Inhalation A high atmospheric concentration can cause anaesthetic effects with possible loss of consciousness. Prolonged exposure may lead to irregular heartbeat and cause sudden death. Higher concentrations may cause asphyxia due to the reduced oxygen content in the atmo- sphere.
DC-C 3. TECHNICAL CHARACTERISTICS 3.1 Unit description The dehumidifers are high-performances units especially designed for industrial or commercial purposes where humidity level should be controlled or water vapor condensation should be prevented. These units are particularly indicated for archives, ironing rooms, bookstores, cheese factories, underground rooms, cellars and industrial sites where high humidity level is present.
DC-C reset, low pressure switch with automatic reset, high pressure safety valve, compressor thermal overload protection, fans thermal overload protection. 3.1.10 Test All the units are fully assembled and wired at the factory, carefully evacuated and dried after leak tests under pressure and then charged with refrigerant R410A.
DC-C 4. INSTALLATION Before undertaking any task the operator must be fully trained in the operation of the machines to be used and their controls. They must also have read and be fully conversant with all operating instructions. All maintenance must be performed by TRAINED personnel and be in accordance with all national and local regu- lations.
DC-C 4.4 Inspection of the labels on the unit, and to take any possible precautions of the case. Not observing the rules reported on this manual can create dangerous situations. After receiving the unit, immediately check its integrity. The unit left the factory in perfect conditions; any eventual damage must be questioned to the carrier and recorded on the Delivery Note before it is signed.
DC-C 4.8 Location and minimum technical clearances The unit has to be installed such that maintenance and repair is possible. The warranty does not cover costs for the provision of lifting apparatus, platforms or other lifting systems required to perform repairs during warranty period. The installation site should be chosen in accordance with EN 378-1 and 378-3 standards.
DC-C Condensate led a syphon with a minimum height equal to the suction pressure of the fan. Discharge pipe 20 mm inside the unit in mm water column 10 Pa 1 mm water column the fan, in any case never less than 35 mm. 4.10 How to vent the unit For a correct operation of the system it is mandatory to remove the air from the hydraulic circuit.
DC-C RGDD Supervision system interface serial board (MODBUS RS485 available only)The installation of the card will allow the unit to be plugged in and connected to a system with MODBUS protocol. This system allows you to remotely monitor all parameters of the unit and change their wiring as shown in the diagram.
DC-C Self-tapping screws Flexible connection ø 3,9 mm or 4,2 mm In order to limit the noise, it is necessary that the air speed inside ducts would never exceed 4 m / sec. With crossing in order to reduce the transmission of vibrations position such as not receive external irradiations or air drafts.
DC-C The electric panel is located inside the unit at the top of the technical compartment where the various components of the refrigerant circuit are also to be found.
