23.1 Parts List a. Len Gordon AS-5TD controller Float-level cord (pre-wired) Contactor Air Switch Circuit Board
23.2 Description The AS-5TD controller is responsible for dedicating power to the 5HP hydraulic motor that runs the swim current when you activate the air button poolside. It has been manufactured with a float-level cord that attaches to the 5HP motor. See Tech Bulletin #22 for additional information on this feature.
23.3 Additional Considerations
The AS-5TD-30 should be installed by a licensed electrician in accordance with national, state, and local electrical codes. Please refer to the attached wiring diagram. As a safety feature, the AS-5TD-30 is equipped with a 30 minute timer. After 30 minutes of operation, the unit will turn itself off. Simply press the air button and the unit will operate for another 30 minutes.
23.4A Wiring (for US and other countries with the same electrical requirements)
Single phase 220 volt 30 amp GFCI protected power should be brought to the two terminals on the left of the black contactor (Line 1 and Line 2). NOTE: The Line 1 wire will be connected directly to the input wire for the 30A in-line fuse and the Line 2 wire will be connected to Terminal 2 of the contactor. Power should then be brought out of the two terminals on the right (Load 1 and Load 2), proceeding to the 5 HP electric motor on the hydraulic power unit. No neutral wire is required. The 5HP hydraulic pump will not operate when wired with a neutral.

The following is a modified wiring diagram for the Circuit Saver. These are 4 wires that need to be run between the AS-5TD controller and the Raypak Electric Heater. Please note that the ground wire is not shown between the controller and heater. For written instructions refer to Technical Bulletin 19.3.
If you choose not to use the circuit saver option refer to schematic diagram on Technical Bulletin 19 for wiring instructions of electric heater and refer to diagram above for wiring instructions for the AS-5TD.
