MAC 2000 Profile IIs, Performances IIs, and Washes before S/N 4015956001 may have their head fan wires swapped in the head. Fixtures with swapped connections may overheat if fan speed regulation (UTIL>FANS>VREG or REG) is enabled.

Our recommendation is that you use the FULL fan speed setting until the fan connections can be checked and corrected.

Note The VREG option is only suitable for 200- 250 VAC supplies and was introduced in the latest release of the software for each product.
