Identify the type of arm/cowl t be used with the unit and the location of each extraction point.
Smear a small amount of silicone grease (item 11) onto the "O" ting in the sleeve of the 75/50 reducer (item 8) and then push fit onto one of the 75 mm connections on the main system.
In the case of XYKT-500-3, push fit solid tube into socket. Again, use silicone grease to ease assembly. The 75 mm pipe work should be fixed to a convenient place on the benches using the cobra clips & screws.
The reducer T section and final reducer Eblow section should be installed under the desired location of the arm. Cobra clips should be used to stabililze these items. Flex tube can be used to connect to the adapter or the base of the articulated arm.
Flex hose should be used to a attach the unit to the 75 mm solid trunking.
Typically volume units will pull air from the closest available source - the nearest arm - leading to strong suction at the first arm and reduced rates down the line. Balance valves are provided in some kits as a means of controlling the air flow rates of the installed system. Optimum flow is achieved by fully opening the valve furthest from the extraction unit while increasingly restricting the flow at positions closer to the unit.
