50 PNEG-900 Series 2000 Autoflow Fan/Heater and Control Installation Instructions
Battery Hook-Up
Two (2) lawn and garden type 12V DC batteries are required for proper operation of the actuator control
box. The two (2) 12V DC batteries are wired in series to provide the 24V DC linear actuator with the voltage
required to operate. The two (2) 12V DC batteries should be mounted on the shelves provided in the
actuator control box.
To wire the two (2) 12V DC batteries to the 24V DC battery charger do the following:
1. Mount the two (2) 12V DC batteries in the actuator control box on the proper shelves.
2. Install a jumper from the negative terminal on one battery to the positive terminal on the other battery.
3. Attach the red wire coming from the fuse block and the positive lead on the 24V DC battery charger
to the open positive terminal on one battery.
4. Attach the black wire coming from the fuse block; and the negative lead on the 24V DC battery
charger to the open negative terminal on the other battery.
5. Use Figure 4N to guide installation.

actuator control box. To test the linear actuator and install the cable do the following:
1. Turn all switches on the Autoflow control front panel to the “OFF” position.
2. Make sure the Emergency Stop switches on all the control boxes are pulled out.
3. Turn the Control Power switch to the “ON” position.
4. The display should read “stopped” at the bottom.
5. While watching the linear actuator turn the Dump switch to the “MANUAL OPEN” position.
12 Volt batteries are not supplied by GSI. Use 12V lawn and garden type mount batteries on battery shelves
in actuator control box 24 volt charger should hook-up to positive and negative as shown. Check polarity.
