C. Check (with a spirit level) to see that the heat pump or air conditioner is level and
plumb. If it is not, take the appropriate corrective action to level and plumb the system.
1/8” thick washers with 1/2” pass through holes can be installed appropriately under the
fastener holes in the base of the heat pump or air conditioner to make the system level
and plumb.
D. Secure the heat pump or air conditioner to the floor with appropriate field supplied
fasteners, through the four 1/2” diameter through holes in the base.
E If the Scholar III™ heat pump or air conditioner is offset from the outside wall, trim
strips should be installed at this time. Check instructions that come with trim strips
for installation or see Appendix D at end of this manual.
F. If appropriate, install wall brackets to the inside surface of the outside wall and to the
cabinet of the Scholar III™ unit, at this time. Check instructions with wall brackets for
installation or see Appendix E at end of this manual.
