RC/RH45 INSTALLATION INSTRUCTIONS (Continued)
8. Once confi dent that all seals are the correct size and in
the proper location and the correct baffl es are attached
to the condenser coil in the proper orientation, slide
unit into fi nal position and tighten any tie down bolts or
screws as necessary.
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
connector 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 bot-
tom panel of the control box (this is also terminated
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.
7. 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 (Figure D7). Install
between wall sleeve and cooling chassis. It is impera-
tive 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 cycling, and constant running of unit. If
installer is in need of more foam than supplied in kit,
consult factory.
*Refer to the charts on page 23 for electrical and optional
electric heat specifi cations.
