OUTLINE DRAWING
Due to RF drive power dissipation, the M1208 requires water-cooling to prevent thermal runaway (>2L/min at < 20degC). The integral NC thermal interlock switch opens at 32 deg C.
The water cooled case parts are aluminium. It is strongly recommended that a corrosion inhibitor is added to the cooling system.
