INSTALLATION - R60C/R60H
Installation
1.
Verify existing wall thickness
. Distance from
condenser coil to outdoor louver varies with wall sleeve
depth. Several sets of air baffles are included with
each unit to accomodate most installations.
Manufacturer offers alternate air baffle kits for unique
applications. Wall sleeve depth is required when
ordering to ensure proper baffle size.
2.
Slide unit into wall sleeve.
If supply duct on cooling chassis does not line up with
supply vent on the room cabinet, the factory installed
weather angle on top and sides will have to be
modified or reoriented. This allows for adjustment to
align with the supply vent when mounting the unit to
the wall sleeve. Slide unit back in wall sleeve to verify
proper fit.
See figure 18.
3.
Install Baffles -
Once the weather angles are verified.
Slide the unit back out of the wall sleeve. Remove
all sets of baffles from the kit bag supplied with unit.
Install only one set of left and right side baffles on the
condenser coil by completing steps below:
•
Choose proper fitting baffles for your application.
Verify selected baffles come in contact with outdoor
louver.
•
Verify baffles are directed inward toward center of coil.
See figure 17.
•
Secure baffles tightly into existing holes of condenser
coil using provided screws.
4.
Install foam tape
— Apply 1/2” x 1/2” open cell
foam strips around supply air duct to ensure all the
conditioned air is delivered into the room. Failure to
follow these instructions will result in recirculation of
conditioned air through the cabinet causing the unit
cabinet to short cycle and coils to freeze. See Figure
21.
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
10to 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.
