SMC Networks MHT2 - Manual (Page 11)

1. Confirm the specifications.
Products represented in this catalog are designed for use in
compressed air appllications only (including vacuum), unless
otherwise indicated.
Do not use the product outside their design parameters.
Please contact SMC when using the products in applications
other than compressed air (including vacuum).
4. Use clean air
If the compressed air supply is contaminated with chemicals,
cynthetic materials, corrosive gas, etc., it may lead to break
down or malfunction.

Warning
1. Instruction manual
Install the products and operate them only after reading the
instruction manual carefully and understanding its contents.
Also keep the manual where it can be referred to as
necessary.
2. Securing the space for maintenance
When installing the products, please allow access for
maintenance.
3. Tightening torque
When installing the products, please follow the listed torque
specifications.
Warning
1. Do not use in environments where the product
is directly exposed to corrosive gases,
chemicals, salt water, water or steam.
2. Do not expose the product to direct sunlight
for an extended period of time.
3. Do not use in a place subject to heavy
vibrations and/or shocks.
4. Do not mount the product in locations where it
is exposed to radiant heat.
Warning
1. Maintenance procedures are outlined in the
operation manual.
Not following proper procedures could cause the product to
malfunction and could lead to damage to the equipment or
machine.
2. Maintenance work
If handled improperly, compressed air can be dangerous.
Assembly, handling and repair of pneumatic systems should
be performed by qualified personnel only.
3. Drain flushing
Remove drainage from air filters regularly. (Refer to the
specifications.)
4. Shut-down before maintenance
Before attempting any kind of maintenance make sure the
supply pressure is shut of and all residual air pressure is
released from the system to be worked on.
5. Start-up after maintenance and inspection
Apply operating pressure and power to the equipment and
check for proper operation and possible air leaks. If operation
is abnormal, please verify product set-up parameters.
6. Do not make any modifications to be product.
Do not take the product apart.
Warning
1. Before piping
Make sure that all debris, cutting oil, dust, etc, are removed
from the piping.
2. Wrapping of pipe tape
When screwing piping or fittings into ports, ensure that chips
from the pipe threads or sealing material do not get inside the
piping. Also, when the pipe tape is used, leave 1.5 to 2 thread
ridges exposed at the end of the threads.
Caution
1. Operating fluid
Please consult with SMC when using the product in
applications other than compressed air (including vacuum).
Regarding products for general fluid, please ask SMC about
applicable fluids.
2. Install an air dryer, aftercooler, etc.
Excessive condensate in a compressed air system may cause
valves and other pneumatic equipment to malfunction.
Installation of an air dryer, after cooler etc. is recommended.
3. Drain flushing
If condensate in the drain bowl is not emptied on a regular
basis, the bowl will over flow and allow the condensate to
enter the compressed air lines.
If the drain bowl is difficult to check and remove, it is
recommended that a drain bowl with the auto-drain option be
installed.
For compressed air quality, refer to “Air Preparation
Equipment” catalog.
