The Right Fit For Comfort
Hydronic Only: Remove the 2-position connector as-
sembly from kit bag supplied with unit (this will have 2
yellow wires attached). Connect this 2-position connec-
tor to the 2-position connection located on the bottom
of the control box panel.
To Connect Aquastat:
A. Remove the black jumper wire located on the
bottom panel of the control box (this is also ter-
minated with a 2-position connector).
B. Cut the jumper wire in the middle and splice the
aquastat to the jumper.
C. Place the connecter back into original location.
Refer to wire diagram on the unit for details.
8. Connect line cord.
9. See Final Inspection and Startup on page 20.
6. 1” x 1” Open cell foam strips are provided to prevent
outside air from entering around the chassis to the room
from the sides and top of the cabinet. Install between
wall sleeve and cooling chassis. It is imperative to have
a solid air seal between wall sleeve and chassis. Failure
to do so will result in air leakage from outdoor to indoor
causing system problems i.e. coils freezing, short cy-
cling, and constant running of unit. If installer is in need
of more foam than supplied in kit, consult factory.
