c. To change indication, push out (remove) red and white

buttons and reassemble in opposite positions.

d. Locate indicator on actuator shaft flats. Press firmly until

location nibs snap into recess on actuator shaft.

AIR SUPPLY AND ELECTRICAL
INSTALLATION

A. 1. Air Supply

The Series 39 Actuator is factory lubricated. For optimum
operation, the use of filtered and lubricated air is
recommended.

2. Air Supply Pressure

Standard double-acting actuators require 40-120 psig supply
air. Spring return actuators require 80-120 psig supply air.
Spring-return actuators can also be set up to operate on
supply air pressures ranging from 40-80 psig by using fewer
springs. See “Rebuilding Instructions”, Spring-Return
Actuator, paragraph 1 on page 9 for proper number and
location of springs for reduced supply air pressures.

4. Recommended Tubing Sizes

In order to provide sufficient flow of supply air to the Series
39 actuator, the following tubing sizes are recommended:

5. Air

Consumption

The following chart shows the amount of pressurized (80
psig) air consumed per stroke in cubic feet. To determine the
total amount of air consumed per complete cycle for double-
acting actuators, simply add the volumes for both the
opening and closing strokes together; for spring-return units,
the total volume of air consumed is the volume shown for
the opening stroke.
