NOTES:
1. Compressor thermally protected internally.
2. All wiring to the unit must comply with NEC and local codes.
3. Transformer is wired to 380 v lead (VIO) for
4. FP1 thermistor provides freeze protection for source water. When using anti- freeze solutions, cut JW3 jumper.
5. Check installation wiring information for controller hookup. Control wiring must be Class 1 and voltage rating equal to or greater than unit supply voltage.
6. Transformer secondary ground via Complete C board standoff and screws to control box. (Ground available from top 2 standoffs as shown.)
7. Aquastat is supplied with unit and must be wired in series with the hot leg of the pump. Aquastat is rated for voltages up to 277 v.
