be seen to aid in starting the bolts.

G. Use a battery drill and run all 4 bolts up until they touch

the template but are not tight.

the 6 wood screws at an angle, so as to stretch and

flatten the template. Three across the front and 3 across

the back of the template. See FIG.. 11.

TORQUE OF 4.5 to 5.7 Nm.

This will compress the roof gasket to approximately

10 mm. The bolts are self locking so over tightening is

not necessary. See FIG. 12.

If bolts are left loose there may not be an

adequate roof seal or if overtightened, dam-

age may occur to the air conditioner base or

ceiling template. Tighten to torque specifi-

cations listed in this manual.
