Product Specific Precautions 2

Be sure to read before handling.
Refer to front matters 42 and 43 for Safety Instructions.

Series

첸

1. Read the instruction manual before mounting the

product.

Read the instruction manual carefully and understand the con-
tents before mounting the product. The manual should also be
kept where it can be referred to whenever necessary.

2. Open the sealed package inside a clean room.

Products specified for clean room are sealed and double pack-
aged inside a clean room. We recommend that the inner pack-
age should be opened inside a clean room or clean environ-
ment.

3. Confirm the mounting orientation of the product.

Since the mounting orientation varies depending on the prod-
uct, check it in the instruction manual or the specifications
herein.
Also, secure all specified mounting positions when using the
product.
If the propagation of the vibration of the pump is not accept-
able, insert vibro-isolating rubber when mounting.

Piping

Caution

1. Flush the piping.

Flush and clean the piping before connecting the product. Any
dirt or scale and the like left in the piping may cause
malfunction or failure.

2. Use fittings with resin threads when connecting pip-

ing to the product with resin threads at the ports.

Using fittings with metal threads may cause damage to the
ports.

3. Tighten screws with proper tightening torque.

When screwing fittings into the product, tighten them with
proper tightening torque as shown below.

1. Use clean air.

Do not use compressed air that includes chemicals, synthetic
oils containing organic solvents, salinities or corrosive gases,
etc., as it can cause damage or malfunction.

2. Pay attention to avoid freezing when operating the

product in low temperatures.

The equipment operates while expanding the compressed air.
During this time, the temperature inside the product decreases
due to adiabatic expansion. If the ambient temperature is low,
using compressed air containing a lot of moisture may cause
freezing because heat cannot be gained from the surround-
ings. In this case, take freeze prevention measures by using a
membrane air dryer (such as series IDG).

Operating Environment

Warning

1. Do not use in the following environments, as this

can cause failure.

1) Locations with an atmosphere of corrosive gases, organic

solvents or chemical solutions, and where there may be
contact with the same.

2) Locations where there is contact with sea spray, water or

steam.

3) Locations where ultraviolet deterioration or overheating of

resin may occur due to direct sunlight.

4) Locations near heat sources with poor ventilation (heat

sources should be shielded by heat insulating material).

5) Locations with impact or vibration.
6) Locations with excessive moisture and dust.

2. The product cannot be used under water.

Do not use the product immersing it in water (liquid). Other-
wise, liquid will enter the openings inside the product, resulting
in malfunction.

3. Compressed air with low dew point

Using super dry air as the fluid may affect the reliability (ser-
vice life) of the equipment, because the lubrication characteris-
tics inside the equipment will deteriorate. Please consult with
SMC when using it.

Caution

1. Quality of operating air

• Be sure to use only air filtrated by a micro mist separator

(such as series AMD). Use of a super mist separator (such
as series AME) is recommended to extend maintenance in-
tervals.

• If a pump is operated by dried air and N

gas, etc., the deteri-

oration of the gaskets inside the switching valve will be ac-
celerated and may result in substantially shortening the life
span of the product.
