72 MSPA-MP Metapacks Service Manual
Instructions to replace an MSPA-MP pack heater configured for
horizontal/back/bottom position.
Note: Make sure to turn power to the pack off before proceeding.
Front/horizontal heater position
To change the heater on a spa configured for back/horizontal heater position
follow the same instructions as for the front/horizontal heater position (shown
on previous pages). The main difference is in the position of the blue plastic
support plate, which sits on the top of the heater in the front position, but is
positioned sideways at the bottom of the pack in the back/horizontal position.
