There is currently only one keypad overlay for the in.k600-5OP, and on some hot tub pack software versions, pumps 4 and 5 will be moved to the upper right and bottom right buttons on the topside instead of the left and right arrows in the center of the keypad.

If the left and right buttons in the center of the keypad are not operating pumps 4 and 5, try pressing the key on the upper right and the key on the bottom right of the keypad.

The ID number of an in.yt pack will always start with 0610- and can be found on the label on the front of the hot tub pack enclosure.

For a 120v-to-240v conversion, please refer to the wiring diagram on the inside of the cover of the hot tub pack for electrical input requirements and heater connection. Also make sure to adjust the breaker/current setting to 80% of the GFCI installed.
