Specific Product Precautions

Selection

1. When releasing air at the intermediate position using a

T-shaped spacer on the inlet side of the lubricator, lubri-

cant may back flow. Therefore, releasing air that does

not contain traces of lubricant is not possible.

To release air that does not contain traces of lubricant,

use a check valve (Series AKM) on the inlet side of the

lubricator to prevent a backflow of the lubricant.

2. If a residual pressure-release 3-port valve is mounted

on the inlet side of the lubricator, causing a backflow of

air, it can result in a backflow of oil or damage to inter-

nal parts. Please do not use it in this fashion.

3. An F.R.L. unit shipped from the plant has its model

number labeled. However, components that are com-

bined together during the distribution process do not

have a label on them.

Caution

Piping

1. When mounting a check valve, make sure the arrow (IN

side) points in the correct direction of air flow.

Warning

Air Supply

1. Use an air filter with 5 µm or less filtration rating on the

inlet side of the valve to avoid any damage to the seat

caused by dust when mounting a 3-port valve for re-

sidual pressure release on the inlet side.

Caution

Mounting and Adjustment

1. When the bowl is installed on the air filter, filter regulator,

lubricator, mist separator, or micro mist separator, install

them so that the lock button lines up to the groove of the

front (or the back) of the body to avoid drop or damage of

the bowl.

Caution

Be sure to read before handling. Refer to back cover for Safety Instructions, “Handling Precautions for SMC

Products” (M-E03-3) and the Operation Manual for F.R.L. Precautions.
