Optional Mounting Plate
Figure 5. Mounting with optional mounting plate
When using the optional mounting plate and closed cell foam gasket, do not over tighten
the mounting bolts. Doing so will cause the mounting plate to warp and result in stress
damage to the heater and fan motor.
IMPORTANT!
After installation, check that the heater casing is not in contact with any parts of the vehicle body.
A failure to do this may result in the hot air fan binding internally (Figure 6).
