2.2.3 Pneumatic piping
- Piping to the compressed air inlet and outlet should be connected with a union of fitting so that it can be
removed.
- Pressing the hexagonal fitting with screw wrench and so on, connect the air piping fittings to the body.
- When mounting any part such as an air filter on the fitting at the compressed air inlet or outlet port,
support the part to prevent excessive force from being applied to the product.
- Be careful not to transmit vibration resulting from the compressor.
- When the compressed air inlet temperature exceeds 50oC, install an aftercooler behind the air
compressor or decrease the temperature of the area where the air compressor is installed to keep it 50oC
or less.
- To prevent foreign matter such as dust from getting in the supply air to the product, flush the piping before
connecting. Dust or oil in the piping can cause cooling failure or other failures of the product. Install a
main line filter to the compressed air source to the product.
- Use a pipe capable of withstanding the specified operating pressure and temperature and connect so
that it will not have leakage.
- Be sure to install a bypass pipe to allow maintenance without stopping the air compressor.
The bypass piping sets
2.2.4 Draining piping
- The drain tube is equipped with a polyurethane tube of outside diameter 10mm. Release the draining end
of the tube to atmosphere to let condensate flow into a water outlet.
- Condensate will be drained regularly using compressed air pressure. Fix the draining end of the tube
firmly to prevent it from vibrating during draining.
- Ensure the drain tube does not rise up.
- Do not bend or crush the drain tube. When installing the product, take care not to place the product on the
drain tube.
Warning
- When draining, follow the user’s own procedure to keep operators safe. (E.g. Wear
protective goggles, apron and gloves to prevent contact with the drained condensate.)
-When oils can enter the drained condensate, waste water treatment is necessary.
Follow the bylaws or rules of the local municipality.
We recommend the bypass piping sets that
we are selling separately as accessories.
