Installation Instructions — R10C | R10H
Installation
Verify the existing wall thickness
1.
— The distance from the
condenser coil to the outdoor louver varies with sleeve depth,
unit(
s
) ship standard with 1 ³∕₈ "(35mm) & 1 ¹∕₂”(38mm) baffles.
In addition, EMI stocks an optional condenser-side air baffle kit
for chassis installation in deeper-than-standard wall sleeves. For
fast, trouble-free installation, know your wall sleeve depth when
ordering.
Verify weather angles
2.
— Slide the unit into the wall sleeve. If
the supply duct on the cooling chassis does not line up with the
supply vent on the room cabinet, it is possible that the factory
installed weather angle on the top and the sides will have to be
reversed. This will allow approximately 1” (25.4mm) of adjust-
ment for alignment with the supply vent when mounting the unit
to the wall sleeve (see Figure 9 and Figure 10). Slide the unit back
in the wall sleeve to verify proper fit.
Install the baffles
3.
— Slide the unit back out of the wall sleeve.
Remove both 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 the proper fitting baffles for your application by verifying
•
selected baffles come in contact with the outdoor louver.
Make sure the baffles are directed inward toward the center of
•
coil (see Figure 11).
Secure baffles tightly into the existing holes of the condenser coil
•
using the screws provided.
NOTICE
The correct condenser air baffles must be installed or performances
may be impaired.
Install the foam tape
4.
— Apply one piece of ¹∕₂” x ¹∕₂” open-cell
poly-foam to top flange of evaporator block off (see FIgure 11).
Install the foam tape
5.
— Apply 2” x 1 ¹∕₂” open-cell foam strips
around supply air duct to ensure that all the conditioned air is
delivered into the room (see Figure 11.) Failure to do so results in
recirculation of the conditioned air through the cabinet causing the
unit to short cycle and coil to freeze.
Install the foam tape
6.
— Apply 1” x 1” open-cell foam strips to
weather angle this prevents outside air from entering around the
chassis to the room from the sides and top of the cabinet. Install
the strips between the wall sleeve and the cooling chassis (see
Figure 12). It is imperative to have a solid air seal between the wall
sleeve and the chassis. Failure to do so will result in air leakage from
outdoor to indoor causing system problems
(example — coils freez-
ing, short cycling, and constant running of unit)
. If there is a need for
more foam than supplied in kit, consult the factory.
Connecting the optional hydronic coil controls
7.
— If the
hydronic heat option has been ordered, then the hydronic coil
will need to be field installed on the new unit. Hydronic coils
are not factory installed and need to be ordered. The coil with
the old unit can be located in the subbase, under the chassis in a
special attachment, or above the chassis in a special attachment.
It is necessary to know where the coil is to be located and the
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.
Remove the 2-position connector assembly 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.
Connecting the accessory Aquastat
8.
— If the accessory
Aquastat has been ordered then it will need to be field installed.
Remove the black jumper wire located on the bottom panel of the
•
control box (
this is also terminated with a 2-position connector
).
Cut the jumper wire in the middle and splice the Aquastat to
•
the jumper.
Place the connector back into original location. Refer to the wir-
•
ing diagram on the unit for details.
Secure the chassis
9.
— Ensure all seals are in the proper loca-
tions, the correct baffles are attached to the condenser coil, and in
the proper orientation, then slide the unit into final position and
tighten any tie down bolts or screws as necessary.
Hard-wired units
10.
— If the unit is hard wired, follow the in-
structions on pages 11 to verify existing wiring and overcurrent
protection. Remove the line cord wires from the PTAC/PTHP
power entrance terminals. Route the power supply wiring through
a strain-relief bushing and connect leads to the power entrance
terminals. Secure the strain-relief clamp. (If wiring is through
conduit, insert the conduit through the control box knockout
and secure in place.)
DO NOT
turn on power until completing
instructions in "Final Inspection and Startup" on page 26.
DO NOT PLUG IN the line cord, if in used condition
11.
. Follow
instructions in "Final Inspection and Startup" on page 26.
