damage not discovered during unloading must be reported
to the carrier within 15 days of receipt of shipment. If not led
within 15 days, the freight company can deny the claim without
recourse. Note: It is the responsibility of the purchaser to le
all necessary claims with the carrier. Notify your equipment
supplier of all damage within fteen (15) days of shipment.
Storage
Equipment should be stored in its original packaging in a
clean, dry area. Store units in an upright position at all times.
Stack units a maximum of 3 units high.
Unit Protection
Cover units on the job site with either the original packaging
or an equivalent protective covering. Cap the open ends of
pipes stored on the job site. In areas where painting, plastering,
and/or spraying has not been completed, all due precautions
must be taken to avoid physical damage to the units and
contamination by foreign material. Physical damage and
contamination may prevent proper start-up and may result in
costly equipment clean-up.
Examine all pipes, ttings, and valves before installing any of
the system components. Remove any dirt or debris found in
or on these components.
Pre-Installation
Installation, Operation, and Maintenance instructions
are provided with each unit. Horizontal equipment is
designed for installation above false ceiling or in a ceiling
plenum. Other unit congurations are typically installed
in a mechanical room. The installation site chosen should
include adequate service clearance around the unit. Before
unit start-up, read all manuals and become familiar with the
unit and its operation. Thoroughly check the system before
operation.
Prepare units for installation as follows:
1. Compare the data on the unit nameplate with ordering
and shipping information to verify that the correct unit
has been shipped.
2. Keep the cabinet covered with the original packaging
until installation is complete and all plastering, painting,
etc. is nished.
3. Verify refrigerant tubing is free of kinks or dents and that

Installation
The Tranquility Cased Coils are designed for upow, horizon-
tal, and downow applications. The coils have a dry nitrogen
holding charge and are equipped with brazing stub refriger-
ant connections for easy installation.
The installer should read the installation manual supplied
with the compressor section for refrigerant line set sizing,
connection procedure, and other important information per-
taining to the system installation.
The installer should:
1. Make sure that the air delivery of the furnace is adequate
enough to handle the recommended CFM and allow for
pressure drop across the air coil, lter, and duct work.
2. Where precise forming of refrigerant lines is required, a
copper tubing bender is recommended for small diameter
tubing. One should avoid sharp bends and contact of the
refrigerant lines with metal surfaces.
3. Refrigerant lines should be protected where they pass
through the raw edges of holes.
4. Coil must be level or slightly pitched toward drain for
proper condensate drainage.
5. Seal the openings into the cabinet to reduce risk of con-
densate blow o from the coil.
The installer should:
1. Disconnect all electrical power to the furnace.
2. For the install of an cased coil, it might be necessary to
fabricate a plate to adapt the coil’s cabinet to the furnace
or air handler air discharge opening.
3. Install the cabinet and level or slightly pitch it as needed to
allow proper condensate drainage.
4. Seal the enclosure as required minimizing air leakage.
5. Connect the refrigerant lines as outlined in the Refrigerant
Lines section.

Applications
Tranquility Cased coils can be applied in upow, downow,
horizontal right and horizontal left applications without
modications. For horizontal applications, installation of an
auxiliary/secondary drain pan is required. For coils that are
two sizes larger than the furnace, for example, a 21” [53.3
cm] wide coil on a 14” [35.6 cm] furnace, a tapered adaptor
with a minimum height of 6” [15.2 cm] is required to evenly
distribute airow. See Figure 3. For coils that are one size
larger than the furnace; for example a 21” [53.3 cm] wide coil
on a 171⁄2” [44.5 cm] furnace, seal the gap between the two
units with sheet metal. See gure 4.
� CAUTION! �
CAUTION! For horizontal applications, the horizontal
drain pan must be located under the indoor coil. Failure
to place the pan under the coil can result in property
damage.

� CAUTION! �
CAUTION! Installation of a factory supplied liquid line
bi-directional lter drier is required. Never install a suction
line lter in the liquid line.
� CAUTION! �
See compressor section IOM for refrigerant charge
information.
Line Set Installation
Figure 9 illustrates a typical installation of an air handler or
cased coil matched to an indoor compressor section. Lineset
lengths should be kept to a minimum and should always be
installed with care to avoid kinking. Line sets are limited to 60
feet [18 meters] in length (one way). Line sets over 60 feet [18
meters] void the equipment warranty. If the line set is kinked or
distorted, and it cannot be formed back into its original shape,
the damaged portion of the line should be replaced. A restricted
line set will eect the performance of the system.
ClimateMaster Split units are shipped with a lter drier (loose)
inside the cabinet that must be installed in the liquid line at the
line set.
All brazing should be performed using nitrogen circulating
at 2-3 psi [13.8-20.7 kPa] to prevent oxidation inside the
tubing. All linesets should be insulated with a minimum
of 1/2” [13mm] thick closed cell insulation. All insulation
tubing should be sealed using a UV resistant paint or
covering to prevent deterioration from sunlight.
When passing refrigerant lines through a wall, seal
opening with silicon-based caulk. Avoid direct contact
with water pipes, duct work, oor joists, wall studs,
oors or other structural components that could transmit
compressor vibration. Do not suspend refrigerant tubing
from joists with rigid straps. Do not attach line set to the
wall. When necessary, use hanger straps with isolation
sleeves to minimize transmission of line set vibration to
the structure.
Installing the Lineset at the Compressor Section
Braze the line set to the service valve stubs as shown in Figure
5. Nitrogen should be circulated through the system at 2-3
psi [13.8-20.7 kPa] to prevent oxidation contamination. Use a
low silver phos-copper braze alloy on all brazed connections.
Compressor section is shipped with a factory charge.
Therefore, service valves should not be opened until the
line set has been leak tested, purged and evacuated.
Installation
Installing the Indoor Coil and Lineset
Figure 6 shows the installation of the lineset and TXV to a
typical indoor coil. An indoor coil or air handler (fan coil) with a
TXV is required. Fasten the copper line set to the coil. Nitrogen
should be circulated through the system at 2-3 psi [13.8-20.7
kPa] to prevent oxidation inside the refrigerant tubing. Use a
low silver phos-copper braze alloy on all brazed connections.

Figure 6: Air Coil Connection
Add-On Heat Pump Applications
The indoor coil should be located on the supply side of
the furnace to avoid condensation damage to the furnace
heat exchanger for add-on heat pump applications. A high
temperature limit switch should be installed as shown
in Figure 9 just upstream of the coil to de-energize the
compressor any time the furnace is energized to avoid
blowing hot air directly into the coil, elevating refrigerant
pressures during operation. The heat pump will trip out on
high pressure lockout without some method of disengaging
the compressor during furnace operation. Alternatively, some
thermostats with “dual fuel” mode will automatically de-
energize the compressor when second stage (backup) heat
is required.
Air Coil
To obtain maximum performance of a newly manufactured
air coil it should be cleaned before start-up. A 10% solution
of dishwasher detergent and water is recommended for both
sides of the coil. A thorough water rinse should follow.
*An LT2 (low temperature air coil protection) sensor is
available for eld installation. Order sensor kit number
S17S0031N12.
Sensing Bulb
IMPORTANT: DO NOT perform any brazing with the TXV
bulb attached to any line. After brazing operations have been
completed, clamp the TXV bulb securely on the suction line
at the 10 to 2 o’clock position with the strap provided in the
parts bag. Insulate the TXV sensing bulb and suction line
with the provided pressure sensitive insulation and secure
with provided wire ties.
IMPORTANT: TXV sensing bulb should be located on a
horizontal section of copper suction line, just outside of
coil box. The copper sensing bulb must never be placed
on any aluminum tube as this will result in galvanic
corrosion and eventual failure of the aluminum tube.
Installation
Evacuation
LEAK TESTING - The refrigeration line set must be pressurized
and checked for leaks before evacuating and charging the
unit. To pressurize the line set, attach refrigerant gauges to
the service ports and add an inert gas (nitrogen or dry carbon
dioxide) until pressure reaches 60-90 psig [413-620 kPa]. Never
use oxygen or acetylene to pressure test. Use a good quality
bubble solution to detect leaks on all connections made in the
eld. Check the service valve ports and stem for leaks. If a leak
is found, repair it and repeat the above steps. For safety reasons
do not pressurize system above 150 psig [1034 kPa]. System is
now ready for evacuation and charging.
Condensate Drain Tubing
Consult local codes or ordinances for specic requirements.
IMPORTANT: When making drain tting connections to the
drain pan, use a thin layer of Teon paste, silicone or Teon
tape and install hand tight.
IMPORTANT: When making drain tting connections to drain
pan, do not overtighten. Overtightening ttings can split pipe
connections on the drain pan.
•Install drain lines so they do not block service access
to front of the unit. Minimum clearance of 24 inches [61
cm] is recommended for lter, coil or blower removal and
service access.
• Make sure unit is level or pitched slightly toward primary
drain connection so that water will drain completely from
the pan. (See Figure 7.)
• Do not reduce drain line size less than connection size
provided on condensate drain pan.
• All drain lines must be pitched downward away from the
unit a minimum of 1/8” per foot [11 mm per m] of line to
ensure proper drainage.
• Do not connect condensate drain line to a closed or
open sewer pipe. Run condensate to an open drain or
outdoors.
• The drain line should be insulated where necessary to
prevent sweating and damage due to condensate forming
on the outside surface of the line.

Installation
• Make provisions for disconnecting and cleaning of the
primary drain line should it become necessary. Install
condensate trap at each unit with the top of the trap
positioned below the unit condensate drain connection
as shown in Figure 7. Design the depth of the trap
(water-seal) based upon the amount of ESP capability
of the blower (where 2 inches [51mm] of ESP capability
requires 2 inches [51mm] of trap depth). As a general
rule, 1-1/2 inch [38mm] trap depth is the minimum.
• Always vent the condensate line when dirt or air
can collect in the line or a long horizontal drain line
is required. Also vent when large units are working
against higher external static pressure than other units
connected to the same condensate main since this may
cause poor drainage for all units on the line. WHEN A
VENT IS INSTALLED IN THE DRAIN LINE, IT MUST
BE LOCATED AFTER THE TRAP IN THE DIRECTION
OF THE CONDENSATE FLOW.
• Auxiliary drain line should be run to a place where it will
be noticeable if it becomes operational. Occupant should
be warned that a problem exists if water should begin
running from the auxiliary drain line.
• Plug the unused drain connection with the plugs
provided in the parts bag, using a thin layer of Teon
paste, silicone or Teon tape to form a water tight seal.
• Test condensate drain pan and drain line after installation
is complete. Pour water into drain pan, enough to ll
drain trap and line. Check to make sure drain pan is
draining completely, no leaks are found in drain line
ttings, and water is draining from the termination of the
primary drain line.
Charging the System
See Compressor Section IOM for charging information.
� CAUTION! �
CAUTION! It is recommended that an auxiliary/secondary
drain pan be installed under units containing evaporator
coils that are located in any area of a structure where
damage to the building or building contents may occur as
a result of an overow of the coil drain pan or a stoppage
in the primary condensate drain piping.
