Series 1700 Size 1 3.2 Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice. 3 General The operational safety and durability of a pneumatic circuit depends on the quality of the compressed air. The compressed air and the moisture increase the rate of wear of the surfaces and seals, reducing the efficiency and the life of the pneumatic components. Furthermore the pressure fluctuation due to a discontinuous demand of air, adversely effect the correct operation of the circuit. To eliminate these disadvantages it is essential to install the service units: filter, pressure regulator and lubricator. Construction andworking characteristics The great advantage of these Air Service Unit’s components is their Modular Design which allows their assembly without the use of additional devices. Two different version have been designed for this size: one made with zinc alloy body and the other with reinforced technopolymer body and threaded brass connections. The bowls are made of transparent technopolymer and are also available with shock resistant technopolymer protection on request, always allowing themoisture and oil level control fromany angle. The filter can be equipped withmanual or semiautomatic water drain valve; furthermore it’s possible to install the automatic draining device inside the bowl. The pressure regulator handle is lockable in the desired position by simply pressing it downwards. The lubricator oil flow is adjustable with proper handle and it is visibly checked through the sight dome. The shut-off valve can be equippedwith pad-lock to prevent accidents or damages due to unauthorized operation. The progressive start-up valve, pneumatically or electropneumatically controlled, allows air supply to the circuit progressively and with adjustable time. The accessories like the wall fixing brackets, pressure gauges with different scales and diameters and the air intake blocks are completing the range. They are assembled between the elements to get filtered or filtered non-lubricated air in the system. Instruction for installation and operation Pay attention to install a group or a single component with air flow direction according to the arrows and to the following sequence: filter, pressure regulator, lubricator and with bowls downwards. The group can be fixed to the wall by removing the covers, which can be installed again after fixing for covering the screws. Do not exceed the recommended torque while assembling the connectors. Do not exceed the recommended air pressure and temperature limits. The moisture should not exceed the level marked on the bowl and it can be drawn off and carried by a flexible tube of Ø 6/4 directly connected to the discharge valve handle. The pressure should be set from minimum to maximum, rotating the adjusting handle clockwise. As lubricant, we suggest to use oil class FD22 or HG32. Verify that the lubricator is not fed with a flow lower than the minimumoperational. To set the oil flow rotate the proper adjusting handle in order to get one drop of oil every 300-600 liters of air. The oil flowwill be kept automatically and proportionally to the air flow. The oil can be refilled by mean of proper plug or directly into the bowl after having de-pressurized the system. Do not exceed the maximum level indicated on the bowl. For opening the shut-off valve push and rotate clockwise the operating handle. For closing it and consequently discharging the down stream line, rotate the handle counter-clockwise. Maintenance Clean the bowls with water and detergent. Do not use alcohol. The filter element made with HPDE is reusable by blowing and cleaning it with proper detergent. For replacing or cleaning it, remove the bowl and unscrew the baffle spins. Replace the pressure regulator diaphragm whenever the operation is not correct or there is a continuos air leaking through the relieving (over pressure discharge); reinstall the adjusting mechanism support, locking it with about 8 Nm torque. In case it is necessary to replace the lubricator transparent dome, tight it at 5 Nm torquemaximum. Assembling
