INSTALLATION - R65C/R65H
Installation
1.
Verify existing wall thickness
. Distance from
condenser coil to outdoor louver varies with wall
sleeve depth. Each chassis includes standard
air baffles to accommodate most common
condenser coil to outdoor louver requirements.
Optional condenser-side air baffle kit for chassis
installation in deeper than standard walls is available.
Weather angles should need no adjustment.
2.
Slide unit into wall sleeve.
If supply duct on cooling chassis does not line up with
supply vent on the room cabinet.
3.
Install Baffles -
Slide the unit back out of the wall
sleeve. Remove baffles from the kit bag supplied
with unit. Install the left and right side baffles on the
condenser coil by completing steps below:
•
Verify selected baffles come in contact with outdoor
louver.
•
Verify baffles are directed inward toward center of coil.
See figure 22.
•
Secure baffles tightly into existing holes of condenser
coil using provided screws.
4.
Install foam tape
— Apply 1” x 1” open-cell foam
strips to prevent outside air from entering around
chassis to room from sides and top of the cabinet.
Install the strips between the wall sleeve and cooling
chassis. Verify a solid air seal between the wall sleeve
and the chassis. Failure to follow these instructions will
result in air leakage from outdoor to indoor causing
system problems. See figure 37.
5.
Connecting optional hydronic coil controls
. If
hydronic heat option has been ordered, field install
the hydronic coil on the new unit. Coil with old unit
can be located in subbase, under chassis in a special
attachment, or above chassis in a special attachment.
It is necessary to know where the coil is to be located
and physical size of the coil so the new coil can be
verified if ordered for replacement. The new coil
should be installed in the same manner as the coil it is
replacing. Hydronic coils are not factory installed and
need to be ordered.
• Remove 2-position connector assembly from kit
bag supplied with unit. This will have 2 yellow wires
attached.
• Connect this 2-position connector to 2-position
connection located on bottom of control box panel.
6.
Connecting accessory field installed Aquastat.
(If
ordered)
A. Remove black jumper wire located on bottom panel
of control box. This is terminated with 2-position
connector.
B. Cut the jumper wire in the middle and splice
Aquastat to the jumper.
C. Place connector back into original location. Refer to
the wiring diagram on unit for details.
7.
Secure chassis —
Verify all seals are in the proper
locations, correct baffles are attached to the condenser
coil, and in proper orientation. Slide unit into final
position and tighten any tie down bolts or screws as
necessary.
8.
Hard-wired units —
A. If unit is hard wired, follow instructions on page 10
to verify existing wiring and overcurrent protection.
B. Remove line cord wires from PTAC PTHP power
entrance terminals.
C. Route power supply wiring through a strain-
relief bushing. Connect leads to power entrance
terminals.
D. Secure strain-relief clamp.
E. If wiring is through conduit, insert conduit through
control box knockout and secure in place.
F. DO NOT turn on power until completing
instructions in "Final Inspection and Startup" on
page 28.
9.
DO NOT PLUG IN the line cord
, if used. Follow
instructions in "Final Inspection and Startup" page 29.
