1. Product Specific Precautions 1

Common Precautions 1 Be sure to read before handling. Design

Warning All models

1. The body material is A6063, the bellows is SUS316L, and other metal seal material is SUS304. Standard seal material in the vacuum section is FKM that can be changed to the other materials (please refer How to Order). Use fluids those are compatible with using materials after confirming.

2. Select materials for the actuation pressure piping, and heat resistance for fittings that are suitable for the applicable operating temperatures.

Models with auto switch 1. Keep the temperature of the switch below 150oC

With heater (thermistor) 1. When using a model with a heater, a mechanism to prevent overheating should be

installed.

Selection

All models 1. When controlling valve responsiveness, take note of the size and length of piping, as well

as the flow rate characteristics of the actuating solenoid valve. 2. Actuating press should be kept within the specified range.0.3 MPa to 0.5 MPa is

recommended. 3. Keep within the specified range of the pilot pressure.

High temperature type

1. If using gases that cause a large amount of deposits, heat the valve body to prevent deposits in the valve.

Mounting

All models 1. In high humidity environments, keep the valve packed until the time of installation. 2. For models with switches, secure the lead wires so that they have sufficient slack, without

any unreasonable force applied to them. 3. Perform piping so that excessive force is not applied to the flange sections. When there is

vibration from heavy objects or attachments, etc., fix piping so that vibration will not apply torque directly to the flange section.

4. Vibration resistance allows for normal operation of up to 30 m/s2 (45 to 250Hz), but continuous vibration may cause a decline in durability. Arrange piping to avoid excessive vibration or impacts.

High temperature type (temperature specification / H0 H4 H5) 1. In models with a heater (thermistor), take care not to damage the insulation components of the

lead wires and connector section. 2. The set temperature for models with a heater should be established without any drafts or heat

insulation. It will change depending on conditions such as heat insulation measures and the heating of other piping. Fine adjustment is not possible.

3. When installing heater accessories or mounting a heater, check insulation resistance at the actual operating temperature. A current leakage breaker or fuse should be installed.

4. If the valve is to be insulated, only the body should be insulated, excluding the bonnet part. 5. In models with a heater, when the heater is in operation, the entire valve becomes hot. Be

careful not to touch it with bare hands, as burns will result.

1. Before mounting, clean the surface of the flange seal and the O-ring with ethanol, etc. 2. There is an indentation of 0.1 to 0.2mm in order to protect the flange seal surface, and it

should be handled so that the seal surface is not damaged in any way.

If the fluid or reaction product (deposit) may cause the valve to become unsafe, the valve should be disassembled, cleaned and re-assembled by an operator who has sufficient knowledge and experience (e.g. a specialist).

1. When removing deposits from the valve, take care not to damage any part of it. 2. Replace the bonnet assembly when the valve is approaching the end of its service life.

* For details regarding endurance cycles, please reference Section 5 of this Operation manual titled Period and scope of warranty. (pages 9)

3. If damage is suspected prior to the end of the service life, perform early maintenance. 4. SMC specified parts should be used for service. Refer to the Construction / Maintenance

parts table. 5. When removing the valve seal and external seal, take care not to damage the sealing

surfaces. When installing the valve seal and external seal, be sure that the O-ring is not twisted. (Refer to Section 6 Parts Replacement Procedure (pages 10 to 13) for details.)

200 VAC 800/40 1600/80 Note 1) Initial power and power consumption are nominal values.

The heaters are PTC thermistor type design. These

thermistors self regulate their temperature by

switching the resistance at certain critical

temperatures, so a separate temperature controller is

unnecessary.

If the temperature of the PTC heaters fitted exceeds

200oC, then it may fail. The maximum operating

temperature for the valve is 150oC. If the heater

temperature is over 200oC or valve temperature is

over 150oC, please use thermostat to control the

heaters to prevent overheating.

With PTC type heaters, there is an initial surge of

current (inrush current) after the power is supplied. These inrush current will reduce overtime. If

multiple heater assemblies are used, the inrush current to the heaters will be magnified and care

should be taken. When multiple heater assemblies or valves are used, do not apply power to the

heater assemblies simultaneously. Keep approximately 30 seconds between applications of power to

each heater assembly. This will allow for incremental spacing to prevent harmful large initial surge.

Vacuum pump Durability test conditions

5 Guaranteed period and range The warranty period is 2 million cycles (under SMC endurance test conditions), 18 months

after delivery or 12 months in service, whichever comes first. Note) The product durability is varied depending on the operating conditions (such as a use with large flow rate). If the specification is not kept, or any non-conformance derived from mounting or replace of a device, an assembly, or an O-ring at your place occurs, the guarantee cannot be applied.

If any failure occurs due to our fault during the guaranteed period, we will guarantee the

non-conformance by delivering a substitute in the worst case. However, responsibility of any damage which is led by the product failure is not taken by us.

Result of durability test (with the circuit

shown on the right) Internal/ external leakage and operation

were checked by opening and closing a valve in internally evacuated condition at ordinary temperature (room temperature).

The test was performed with FKM, the standard sealing material.

The pumping direction is not limited, but if the pumping creates a flow stream, the endurance of the valve could be impaired. Therefore, the pumping direction shown on the right figure (bellows side pumping) is recommended. Also, the operating conditions should be checked beforehand because it affects the life.
