Installation
1.
Verify existing wall thickness
. Distance from
condenser coil to outdoor louver varies with wall sleeve
depth. Units shipped with factory installed baffles.
Manufacturer offers alternate air baffle kits for unique
applications. Wall sleeve depth is required when
ordering to ensure proper baffle size.
2.
Install Baffles -
Remove sets of baffles from the
kit bag supplied with unit. Install only one set of left
and right side baffles on the condenser coil. Complete
following steps:
•
Choose proper fitting baffles for your application.
Verify selected baffles come in contact with outdoor
louver.
•
Install top bafffle.
•
Verify baffles are directed inward toward center of coil.
See figure 6.
•
Secure baffles tightly into existing holes of condenser
coil using provided screws.
Install Kit Contents:
(1) Top Baffle
(2) Size 1 left and right baffles only
(2) Size 2 left and right baffles
(2) Size 3 left and right baffles
(2) Size 4 left and right baffles
3.
Install thermostat bulb and filter:
• Insert grommets into clips.
• Insert sensing bulb into grommets.
• Insert Thermostat bulb assembly into middle section
of indoor coil. See figure 7.
•
Fasten filter using velcro strips.
4.
Install foam tape
— Apply 1∕2” x 1∕2” open cell foam
strips to both weather angles, prevents outside air
from entering around the chassis to the room from the
sides. See figure 8.
Install 1" x 1" open cell foam to back of unit above
condenser coil. It is necessary 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.
Contents of install kit:
(3ft) 1"x 1" Open cell foam
(5ft) 1/2" x 1/2" Open cell foam
(6.6ft) 1" x 1/2" Open cell foam
R15C - INSTALLATION
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.
• Splice 2 yellow wires to valve motor using 2 - crimp
popcorn.
• 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 jumper wire in the middle and splice the
Aquastat to jumper using 2 - crimp popcorns.
C. Place connector back into original location. Refer to
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.
