Installation Tips
-
Confirm the chip number on your old board matches EL2000M3R2 before ordering.
-
Installs only in the plastic control box—won’t fit a metal enclosure.
-
Use the provided heater-retro molex connector (48-0023) on newer models.
-
If your circulation pump and ozone output share voltage, ensure both circuits use the same line voltage.
-
Follow the EL2000 Mach 3 wiring schematic for your spa make/model to avoid miswiring which voids warranty.
