Just install a circuit breaker in your pool equipment panel and run wire. . .
Heat Siphon has a separate molded -in junction box with a standard electrical conduit nipple already in place.
Just remove four screws and the small cover, feed your supply lines in through the conduit nipple and wire-nut the electric supply wires to the three pigtails already in the junction box. (four wires if three phase)
To complete electrical hookup connect Heat Siphon by electrical conduit, UF cable or other suitable means of the proper size wire (as permitted by local electrical codes) to a dedicated AC power supply branch circuit equipped with the proper circuit breaker, disconnect or time delay fuse protection.
Electrical bonding is required to a local earth ground (separate from the power supply grounding) through a solid copper conductor not smaller than #8 size. This bonding wire should also be connected to any other pool or spa system electrical equipment.
Heat Siphon has a standard copper bonding lug located on the right side of the unit facing the front panel.
Disconnect Means Required
For safety reasons, a disconnect means ( fused or un-fused switch or circuit breaker) should be located within sight of and readily accessible from your Heat Siphon. This is common practice on commercial and residential air conditioners and heat pumps. It prevents remotely energizing unattended equipment and permits turning off power at the unit while the unit is being serviced.
