UNIT LOCATION
DANGER
Appliances must not be installed where they may be exposed to
potentially explosive or flammable atmosphere.
Handling
Each unit will be shipped to the site on a wood skid. Whenever
possible, all lifting and handling of the unit should be done with
the packing and skid in position.
When slinging or using a forklift to lift the unit, the support points
should be sufficiently apart to give stability when lifting. Unless
otherwise noted, the lifting points should be equidistant from the
centerline. Extreme care should be taken not to drop the unit
Considerable damage can occur to the unit during positioning,
in particular, to the paneling and exterior paint. Use an adequate
number of personnel and the correct tools when moving the unit.
The unit is designed to remain upright so care should be taken
when lifting the unit up steps.
The use of torque screwdrivers on panel, cover or component
mounting screws is not recommended. Hand-start all screws.
If electric drills are used – set at the lowest possible torque.
Storage
Equipment should be stored in clean, dry area and in its original
packaging.
Do not store or install units in corrosive environments or
in locations subject to temperature or humidity extremes.
Performance, reliability, and service life can be significantly
reduced. Transport and store units in an upright position.
Unit Protection
To prevent damage, keep the unit in its original packaging or
cover with an equivalent protective covering while on the job
site. Cover open connections to prevent debris from entering the
system. Take extra precautions to protect the unit from damage
or contamination when in an area where spraying, plastering
and / or painting has not been completed. Physical damage or
contamination from foreign debris may prevent proper start-up
and costly equipment clean-up. Examine all fittings, valves, or
pipes and remove all dirt or debris before installing unit.
Electrical
Electrical wiring should be done in accordance with all
applicable national and local codes. It is the responsibility of the
electrical contractor to adhere to such codes. The warranty will
be voided if wiring is not in accordance with the specifications of
the unit. Modine recommends using copper conductors only.
All power supply wiring must be capable of carrying the
maximum current load under no fault conditions at the stipulated
voltages. Care should be taken to avoid significant voltage drops.
A knockout for power connection is provided on the access side
of the unit. See unit dimensions in Figures 3.1 and 4.1.
INSTALLATION
A conventional fossil fuel forced air furnace may also be used for
an air handler, as well as a alternative heat source, provided a
dual-fuel capable thermostat is used. The furnace must provide
airflow within +/- 5% of the airflows shown in Table 10.1. The
furnace must be disabled until auxiliary heating is called for, then
the heat pump must be disabled when the furnace takes over
the heat load. Refer to the furnace manufacturer’s installation
instructions for directions on installation of the furnace, coil, and
wiring. A Dual Fuel Thermostat is required to prevent damage to
the Split Unit.
Installation of these units is to be INDOORS only. The instructions
detailed below are for the Installation of a “Standard” unit.
Accommodations and adjustments will be required for the usage of
additional unit accessories. Should assistance be required for the
installation of these additional items, consult Modine at the phone
number listed on the back cover of this manual.
Modine Cased Coils are designed for upflow, downflow, and
horizontal (left and right) applications. Modifications are not
required for Cased Coils applied in the upflow and downflow
applications; however, the addition of a horizontal drain pan is
required for horizontal applications. The horizontal conversion
kit part numbers can be found in Table 6.1. Refer to GEO 16-
522 for conversion instructions.
The coils are shipped with a dry nitrogen holding charge and
come standard with ODF braze refrigerant connections to
ensure easy installation. The factory installed thermal expansion
valves are pre-set for optimal performance with a matched
Modine Split Condensing Unit.
CAUTION
1. For horizontal applications, the horizontal drain pan must
be installed. Failure to do so will result in property damage.
2. Coils must be installed on the supply airflow side of
furnace.
Figure 5.1 - Cased Coil
Preparation
1. If the installation has multiple units, check that unit
identifications correspond with the network diagrams. Advise
Modine immediately if discrepancies are noted.
2. Remove any Accessory Kits and shipping support material
from the mechanical compartment.
3. Check refrigerant piping for dents or kinks.
4. Ensure that aluminum distributor tubes and thermal
expansion valve capillary tubing has not come into contact
with any sheet metal brackets, or coil flanges. Do not re-bend
distributor leads. Aluminum should not be re-bent.

INSTALLATION
Location and Installation Considerations
1. It is highly recommended that the unit is located in a
conditioned space that is not subject to freezing and where
humidity levels are controlled so as not to could cause
cabinet condensation.
2. Provide adequate clearance for front access panels. A
minimum of 30” of clearance on the front side of the coil
should be provided.
3. The unit can be serviced entirely from the front. Be sure to
route primary and second condensate drain lines so as not
to interfere with access and maintenance.
4. The air delivery of the furnace must deliver the airflow and
static as specified in Table 10.1.
5. Coils must be installed on the supply airflow side of the furnace.
6. Horizontal applications require the addition of a horizontal
drain pan conversion kit. Refer to Table 6.1 for part numbers
and GEO-16-522 for conversion instructions.
7. Use screws with a maximum length of 3/8" to connect
ducting or duct collars to the unit.
8. Use of flexible duct collars and use of acoustical duct liners
are good installation practices that ensure quiet operation.
9. Provide adequate room to make refrigerant, electrical and
duct connections.
10. It may be necessary to fabricate a special plate to adapt the
coil casing to the furnace air discharge opening.
11. A tapered transition, with a 6" minimum length, is required to
evenly distribute airflow where the furnace cross flow area is
significantly different from that of the coil casing.
12. Provide a clear physical path to the unit. Adequate space
should be provided to allow removal of the unit, if necessary.
13. Allow adequate room below a horizontal unit for a
condensate drain trap.
14. Should the coil section be installed in a non-conditioned
space such as an attic, garage or crawl space, a full
size secondary drain pan must be provided to prevent
damage from condensate run-off. In this application, it is
recommended that the unit exterior be completely insulated
with a minimum of 1" thick fiberglass insulation with a vapor
barrier on the outside.
All ductwork must be designed and installed in accordance with
local codes.
Note: The coils are equipped with a supply air duct flange
to facilitate installation. The size of the supply duct must be
designed to transport the rated unit airflow. Proper transition to
the coil duct flange must be utilized.
Furnace Transition and Duct Mounting
1. Ensure evenly distributed airflow between the furnace and the
coil. If the cased coil footprint is substantially different than
that of a matched furnace, it may be necessary to fabricate
either an adapter plate or a tapered transition. The tapered
section should have a minimum transition length of 6".
2. Depending on the configuration, the brackets shown in Figure
6.1 may be utilized to attach the furnace supply, duct system
or transition to the top side of the cased coil.
3. If screws are used to connect the furnace supply, duct system
or transition to the bottom of the cased coil, keep the screws
within the bottom 1" of the casing and only use on the two
sides and back of the casing. Do not use screws on the front
access cover. In addition, screws should have a maximum
length of 3/8". Figures 3.1, 4.1 and 6.2 show the casing
mounting area and dimensions, respectively.
4. If the duct construction around an uncased coil will be
fastened to the uncased coil, screws may only be used in the
bottom 1" of the lower base frame and the sides of the front
connection mounting plate, as shown in Figure 6.2. Do not
install screws into the drain pan or any part of the coil.
5. Ensure that duct joints are sealed airtight, per local codes.
6. Check that the unit is level from side-to-side and frontto-back. the drain pan is pitched to facilitate condensate
removal.
7. All field wiring entry points must be sealed airtight.

Duct System
The duct system must be designed to transport the rated unit
ariflow quietly and efficiently. For maximum blower sound
attenuation, it is recommended that the first few feet of the
supply and return plenums include an internal fiberglass duct
liner or be constructed of ductboard. On metal duct systems,
canvas connectors should be incorporated between the unit
and ductwork. Installing the coil section to uninsulated metal
ductwork in an unconditioned space will result in poor system
performance and lead to condensation formation on the duct
and possible structural damage.
If existing ductwork is utilized, verify that duct system can
accommodate the rated airflow. If the ductwork is undersized,
larger ductwork should be installed. All existing ductwork should
be checked for leaks and repaired as required.

INSTALLATION
Horizontal Installation
1. Refer to Horizontal Conversion Kit instructions if field
conversion is required.
2. The coil may be installed on any level surface strong enough to
support the weight and isolated to prevent sound transmission.
Vibration isolators (by others) are recommended.
3. When installed in an attic or above a drop ceiling, the
installation must conform to all local codes.
4. If the unit is suspended, typically 3/8"-16 threaded rods with a
unistrut or other suitable framing systems are employed. The
entire length of the unit must be supported.
5. If the coil is installed on the attic floor, the unit should be set
in a full size secondary drain pan. The secondary drain pan
should be set on top of a vibration absorbing mesh, on a
plywood base. A secondary drain pan should be used when
installed over a finished living area to provide protection from
water damage in case the primary drain line becomes plugged.
The secondary drain line should terminate somewhere that
is easily visible by the homeowner. Be certain to show the
homeowner the termination location of the secondary drain
line and to explain its purpose. If the coil is installed in a crawl
space, the bottom of the coil must be at least 4” above grade to
prevent flooding during heavy rains.
6. Check that the unit is level from side-to-side and front–to-back.
The drain pan is pitched to facilitate condensate removal.
7. All field wiring entry points must be sealed airtight.
Condensate Piping
The coil drain pan has two 3/4" NPT stainless steel drain fittings.
When the coil is configured for horizontal airflow, four fittings
are present. The two “upper” or “vertical” drain fittings must be
plugged.
1. The drain pan has a primary and auxiliary drain connection.
It is recommended that both the primary and auxiliary drains
are utilized. The installer must always follow local codes
when running condensate drain piping.
2. As the coil sections are not internally trapped, a trap must
be installed in the drain line below the bottom of the drain
pan to ensure free condensate flow (see Figure 8.1). Install
drain lines so that they do not block service access to the
front of the unit or furnace.
3. The coil drain connections must be connected to a drain line
and pitched away from the unit a minimum of 1/8” per foot to
allow the condensate to flow away from the coil.
4. The primary condensate drain must be terminated to an
open drain or sump. Do not connect the condensate drain
to a closed waste system.
5. An open vertical air vent should be installed to overcome
line length, friction and static pressure.
6. Make provisions for disconnecting and cleaning of the
primary drain line should it become necessary.
7. It is recommended that the auxiliary drain be connected to a
drain line for all units.
8. The auxiliary drain should be run to an area where the
homeowner will notice it draining.
9. The drain line should not be smaller than the drain
connection at the condensate pan.
10. The drain line contains cold water and should be insulated
in unconditioned spaces to avoid drain line condensation
from dripping on ceiling, etc.
11. If the coil section is located in an unconditioned space, water in
the trap may freeze. It is recommended that the trap material be
of a type that will allow for expansion of water when it freezes.
12. Test condensate drain pan and drain line after installation
is complete. Pour enough water into drain pan to fill drain
trap and line. Check to make sure drain pan is draining
completely, no leaks are found in drain line fittings, and water
is draining from the termination of the primary drain line.
13. It is always recommended that a secondary drain be
installed under a horizontal coil.
14. Drain lines must be in conformance with local codes
Figure 8.1 - Condensate Trap Example
Secondary Drain Pan Overflow Switch
It is highly recommended a normally closed, condensate overflow
switch be installed in the secondary drain pan and wired to
the split system terminal strip. When installed, the controller will
shut down the unit in the event of a plugged condensate drain line.
Failure to wire the switch to unit may result in damage to the furnace
or property.
Wire terminals are provided in the control panel for easy connection
of overflow switch. Remove the BLUE jumper between the
terminals and tie in the secondary drain pan overflow switch leads.
Refrigerant Line Sets
Refer to the Split Unit installation manual (GEO16-501) for for
line sizing and line set guidelines.
Thermal Expansion Valve
The coil section is equipped with a TXV that is pre-set from the
factory for optimized cooling. No adjustment is necessary unless
service has been done on the TXV. Table 10.2 shows the coil
TXV initial factory settings. Note that the matched Split system
has two TXV’s, each with independent factory settings. One TXV
is include with the coil and one is installed in the Split unit. Refer
to the Split Ground Source Unit I&S manual for the TXV settings
at the Split unit.
Air Coil
To ensure maximum performance, it is recommended that the
air coil be cleaned before startup. A solution of 10% dishwasher
detergent and water is recommended. Spray both sides of the
coil followed by a thorough clean water rinse.
