Installer Responsibilities
CAUTION
Sharp edges on sheet metal and fasteners can cause
personal injury. This equipment must be installed,
operated, and serviced only by an experienced
installation company and fully trained personnel.
The installation of this equipment shall be in accordance
with the regulations of authorities having jurisdiction and all
applicable codes. It is the responsibility of the installer to
determine and follow the applicable codes.
Receiving Inspection
When the equipment is received, all items should be carefully
checked against the bill of lading to be sure all crates and
cartons have been received. If the unit has become dirty
during shipment (winter road chemicals are of particular
concern), clean it when received.
All units should be carefully inspected for damage when
received. Report all shipping damage to the carrier and le a
claim. In most cases, equipment is shipped F.O.B. factory and
claims for freight damage should be led by the consignee.
Before unloading the unit, check the unit nameplate to make
sure the voltage complies with the power supply available.
Service Clearance
CAUTION
Location. Care should be taken for the installation
location to minimize snow drifts on the outdoor coil.
Allow service clearances as approximately indicated in Figure
1. Also, Daikin recommends providing a roof walkway to the
rooftop unit as well as along each side of the unit that provides
access to most controls and serviceable components.
Refer to NEC and local for minimum clearances around the
unit and control panel.
Ventilation Clearance
Below are minimum ventilation clearance recommendations.
The system designer must consider each application and
provide adequate ventilation. If this is not done, the unit may
not perform properly.
Unit(s) Surrounded by a Screen or a Fence:
1. The bottom of the screen or fence should be at least 1 ft.
(305 mm) above the roof surface.
2. The distance between the unit and a screen or fence
should be as described in Figure 1.
3. The distance between any two units within a screen or
fence should be at least 120" (3048 mm).
Unit(s) Surrounded by Solid Walls:
1. If there are walls on one or two adjacent sides of the unit,
the walls may be any height. If there are walls on more
than two adjacent sides of the unit, the walls should not
be higher than the unit.
2. The distance between the unit and the wall should be at
least 96" (2438 mm) on all sides of the unit.
3. The distance between any two units within the walls
should be at least 120" (3048 mm).
Do not locate outside air intakes near sources of contaminated air.
If the unit is installed where windy conditions are common,
install wind screens around the unit, maintaining the
clearances specied (see Figure 1). This is particularly
important to maintain adequate head pressure control when
mechanical cooling is required at low outdoor air temperatures.

Overhead Clearance
1. Unit(s) surrounded by screens or solid walls must have
no overhead obstructions over any part of the unit. For
heat pump models overhead obstructions could allow the
formation of dangerous ice cycles.
2. The area above the condenser must be unobstructed in
all installations to allow vertical air discharge.
3. The following restrictions must be observed for overhead
obstructions above the air handler section:
a. There must be no overhead obstructions above the
furnace ue, or within 9" (229 mm) of the ue box.
b. Overhead obstructions must be no less than 96"
(2438 mm) above the top of the unit.
c. There must be no overhead obstructions in the areas
above the outside air and exhaust dampers that are
farther than 24" (610 mm) from the side of the unit.
Roof Curb Assembly and Installation
WARNING
Mold can cause personal injury. Some materials such
as gypsum wall board can promote mold growth when
damp. Such materials must be protected from moisture
that can enter units during maintenance or normal
operation.
Locate the roof curb and unit on a portion of the roof that can
support the weight of the unit. The unit must be supported to
prevent bending or twisting of the machine.
If building construction allows sound and vibration into
the occupied space, locate the unit over a non-critical
area. It is the responsibility of the system designer to
make adequate provisions for noise and vibration in the
occupied space.
Install the curb and unit level to allow the condensate drain to
ow properly and allow service access doors to open and close
without binding.
The gasketed top surface of the curb seals against the unit
when it is set on the curb. These anges must not support
the total weight of the duct work. See Installing Ductwork on
page 13 for details on duct connections. It is critical that
the condensate drain side of the unit be no higher than the
opposite side.
Assembly Instructions
Assembly of a typical roof curb is shown in Figure 2, Figure 3
on page 8 and Figure 4 on page 9.
1. Set curbing parts A thru G per dimensions shown over roof
opening or on a level surface. Note location of supply air
opening. Check alignment of all mating screw holes.
2. Screw curbing parts together using fasteners provided.
Leave all screws loose until curb is checked to be square.
3. Square entire curbing assembly and securely tighten all
screws.
4. Position curb assembly over roof openings. Curb must
be level within 0.25 inches from side to side and 1.50
inches over its length. Check that top surface of curb is
at with no bowing or sagging.
5. Weld curb assembly in place. Caulk all seams watertight.
Remove backing from 0.25 × 1.50 wide gasket and apply
to surfaces shown by crosshatching.
6. Check that electrical connections are coordinated.

Rigging and Handling
WARNING
Only trained and qualified personnel should be allowed
to rig loads or operate load rated cranes and/or hoist
assemblies. Do not use a forklift to lift or maneuver the
unit. Failure to use a load rated crane or hoist assembly
to lift or maneuver the unit can cause severe personal
injury and property damage.
WARNING
Use all lifting points. Improper lifting can cause property
damage, severe personal injury, or death.
CAUTION
Lifting points may not be symmetrical to the center
of gravity of the unit. Ballast or unequal cable lengths
may be required.
CAUTION
Unit is equipped with fork slot reenforcement pieces.
These need to be removed before unit is set on the curb.
Rigging holes for shackles are integral on the unit base. Use
four independent lines, securing one end of a line to a
unit base lifting point and the other end of the line to an
associated spreader bar lifting point. Figure 5 and Figure 6
are examples of instruction labels shipped with each unit.
Use spreader bars to prevent damage to the unit cabinet. Avoid
twisting or uneven lifting of the unit. The cable length from the
bracket to the hook should always be longer than the distance
between the outer lifting points.
If the unit is stored at the construction site for an intermediate
period, take these additional precautions:
1. Support the unit well along the length of the base rail.
2. Level the unit (no twists or uneven ground surface).
3. Provide proper drainage around the unit to prevent
ooding of the equipment.
4. Provide adequate protection from vandalism, mechanical
contact, etc.
5. Securely close the doors.
6. Cover the supply and return air openings.

Unit Piping - Condensate Drain Connection
WARNING
Drain pans must be cleaned periodically. Material in
uncleaned drain pans can cause disease. Cleaning
should be performed by qualified personnel.
The unit is provided with a condensate drain connection, a 3/4"
male NPT for 003–015 units and a 1" male NPT for 016–028
units. For proper drainage, level the unit and drain pan side to
side and install a P-trap.
Figure 7 shows the layout of the condensate drain connection.
The distance from the drain pan outlet to the horizontal run of
the P-trap should be a distance of twice the static pressure in
the drain pan.
Example: If the static pressure as measured in the drain pan
is 1.5", then the distance between the drain outlet and the
horizontal run should be 3".
Draining condensate directly onto the roof may be acceptable;
refer to local codes. Provide a small drip pad of stone, mortar,
wood, or metal to protect the roof against possible damage.
If condensate is piped into the building drainage system, pitch
the drain line away from the unit a minimum of 1/8" per foot.
The drain line must penetrate the roof external to the unit.
Refer to local codes for additional requirements. Sealed drain
lines require venting to provide proper condensate ow.
Periodically clean to prevent microbial growth/algae buildup
from plugging the drain and causing the drain pan to overow.
Clean drain pans to prevent the spread of disease. Cleaning
should be performed by qualied personnel.
Figure 7: Condensate Drain Connection
Damper Assemblies
The optional damper assemblies described in this section
are ordered with factory-installed actuators and linkages.
The following sections describe the operation and linkage
adjustment of the factory option.
Figure 8: Damper Assembly

As the single actuator modulates, the outside air dampers
open, the return air dampers close, and the exhaust air exits
the unit through the gravity relief dampers.
The economizer comes with manually adjustable linkage (Figure
8). The damper is set so that the crank-arm moves through
a 90-degree angle to bring the economizer dampers from full
open to full close. Mechanical stops are placed in the crank-arm
mounting bracket. Do not remove stops. Driving the crank-arm
past the stops results in damage to the linkage or damper.
Outdoor Air Dampers (0% to 30%)
These dampers are intended to remain at a xed position during
unit operation, providing fresh air quantities from 0 to 30% of the
total system airow, depending on the damper setting.
The damper position may be set at the unit controller keypad
(refer to OM 1141 for further detail). During unit operation, the
damper is driven to the position set at the unit controller. During
the OFF cycle, the damper is automatically closed.

Cabinet Weather Protection
CAUTION
Transportation, rigging, or maintenance can damage
the unit’s weather seal. Periodically inspect the unit
for leakage. Standing moisture can promote microbial
growth, disease, or damage to the equipment and
building.
This unit ships from the factory with fully gasketed access
doors and cabinet caulking to provide weather resistant
operation. After the unit is set in place, inspect all door gaskets
for shipping damage and replace if necessary.
Protect the unit from overhead runoff from overhangs or other
such structures.
Installing Ductwork
WARNING
Mold can cause personal injury. Materials such as
gypsum wall board can promote mold growth when
damp. Such materials must be protected from moisture
that can enter units during maintenance or normal
operation.
On vertical-supply/vertical-return units, if a Daikin roof curb
is not used, the installing contractor should make an airtight
connection by attaching eld fabricated duct collars to the
bottom surface of the unit’s duct opening. Do not support the
total weight of the duct work from the unit.
Use exible connections between the unit and ductwork to
avoid transmission of vibration from the unit to the structure.
To minimize losses and sound transmission, design duct work
per ASHRAE and SMACNA recommendations.
Where return air ducts are not required, connect a sound
absorbing T or L section to the unit return to reduce noise
transmission to the occupied space.
Ductwork exposed to outdoor conditions must be built in
accordance with ASHRAE and SMACNA recommendations
and local building codes.

Installing Duct Static Pressure Sensor Taps
For all VAV units, duct static pressure taps must be eld
installed and connected to the static pressure sensor 1 (SPS1)
in the unit. Sensor SPS1 is standard on VAV units and is
located in the main control panel.
Carefully locate and install the duct static pressure sensing
tap. Improperly locating or installing the sensing tap causes
unsatisfactory operation of the entire variable air volume
system. Below are pressure tap location and installation
recommendations. The installation must comply with local code
requirements.
1. Install a tee tting with a leak-tight removable cap in each
tube near the sensor tting. This facilitates connecting a
manometer or pressure gauge if testing is required.
2. Use different colored tubing for the duct pressure (HI)
and reference pressure (LO) taps, or tag the tubes.
Daikin recommends 3/16" ID tubing.
3. Locate the duct pressure (HI) tap near the end of a long
duct to ensure that all terminal box take-offs along the
run have adequate static pressure.
4. Locate the duct tap in a nonturbulent ow area of the
duct. Keep it several duct diameters away from take-off
points, bends, neckdowns, attenuators, vanes, or other
irregularities.
5. Use a static pressure tip (Dwyer A302 or equivalent) or
the bare end of the plastic tubing for the duct tap. (If the
duct is lined inside, use a static pressure tip device.)
6. Install the duct tap so that it senses only static pressure
(not velocity pressure). If a bare tube end is used,
it must be smooth, square (not cut at an angle) and
perpendicular to the airstream (see Figure 10).
7. Locate the reference pressure (LO) tap near the duct
pressure tap within the building. If the tap is not connected
to the sensor, unsatisfactory operation will result.
8. Route the tubes through the curb and feed them into the
unit through the knockout in the bottom of the control
panel (see Figure 9). Connect the tubes to appropriate
barbed ttings (on SPS1) in the control panel. (Fittings
are sized to accept 3/16" ID tubing.)

Figure 10: Duct Static Pressure Sensing Tubing Installation
Installing Building Static Pressure Sensor Taps
CAUTION
Fragile sensor fittings. If you must remove tubing
from a pressure sensor fitting, use care. Do not use
excessive force or wrench the tubing back and forth to
remove or the fitting can break off and damage sensor.
If a unit has building static pressure control capability, you
must eld install and connect static pressure taps to the static
pressure sensor SPS2 in the unit. This sensor is located at the
bottom of the main control panel next to SPS1.
Carefully locate and install the two static pressure sensing
taps. Improper location or installation of the sensor taps causes
unsatisfactory operation. Below are pressure tap location and
installation recommendations for both building envelope and
lab, or “space within a space” pressure control applications.
The installation must comply with local code requirements.
Building Pressurization Applications
1. Install a tee tting with a leak-tight removable cap in each
tube near the sensor tting. This facilitates connecting a
manometer or pressure gauge if testing is required.
2. Locate the building pressure (high) tap in the area that
requires the closest control. Typically, this is a ground
level oor that has doors to the outside.
3. Locate the building tap so it is not inuenced by any
source of moving air (velocity pressure). These sources
may include air diffusers or outside doors.
4. Route the building tap tube through the curb and feed
it into the unit through the knockout in the bottom of the
control panel (refer to Figure 9). Connect the 3/16" ID
tube to the (high) tting for sensor SPS2.
5. Locate the reference pressure (low) tap on the roof.
Keep it away from the condenser fans, walls, or anything
else that may cause air turbulence. Mount it high
enough above the roof so it is not affected by snow. Not
connecting the reference tap to the sensor results in
unsatisfactory operation.
6. Use an outdoor static pressure tip (Dwyer A306 or
equivalent) to minimize the adverse effects of wind.
Place some type of screen over the sensor to keep out
insects. Loosely packed cotton works well.
7. Route the outdoor tap tube out of the main control panel
through a small eld-cut opening in the upright. Seal the
penetration to prevent water from entering. Connect the
3/16" ID tube to the (low) tting for sensor SPS2.
Discharge Air Temperature Sensor
The discharge air temperature sensor must be installed in the
discharge air duct, downstream of the rooftop unit. Locate the
sensor in a location that closely approximates the average
duct temperature. To avoid the effects of radiation, the sensor
should not be in the line-of-sight of a gas furnace or electric
heater. Generally, locate sensor in the center of a duct wall,
5′ – 10′ from unit opening to allow for air mixing. Do not mount
down stream of VAV boxes or other dampers.
Installation: Drill 7/8" diameter hole in duct, insert sensor probe
and secure plate to duct with 2 – #10 screws. Be sure to apply
gasket or silicone sealant to back of mounting plate prior to
screwing plate to the duct to create an air-tight seal.

DANGER
Hazardous voltage. Can cause severe injury or
death.
Disconnect electric power before servicing equipment.
More than one disconnect may be required to de-
energize the unit.
WARNING
Provide proper line voltage and phase balance.
Improper line voltage or excessive phase imbalance
constitutes product abuse. It can cause severe damage
to the unit’s electrical components.
WARNING
Electrical shock hazard. Can cause severe injury or
death.
Connect only low voltage NEC Class II circuits to
terminal block TB2.
DANGER
Overheating or failure of the gas supply to shut off can
cause equipment damage, severe personal injury or
death. Turn off the manual gas valve to the appliance before
shutting off the electrical supply.
Pre-Construction
The Rebel unit comes equipped with a Microtech III controller
and can be used for sites that are still under construction. The
following conditions must be met.
1. Ductwork has to be installed. The fan proving switch
and furnace might not run correctly without the specied
external static pressure
2. Filters must be installed.
3. Follow furnace commissioning instructions found in the
furnace section.
4. After substantial completion of the construction process
the unit is to be thoroughly cleaned. Special attention
should be paid to the indoor DX coil and the furnace.
Filters should be changed
5. Furnace operation, rate, and temperature rise should be
re-veried. See instructions found in the furnace section.
Lab Pressurization Applications
1. Install a “T” tting with a leak-tight removable cap in each
tube near the sensor tting. This facilitates connecting a
manometer or pressure gauge if testing is required.
2. Use different colored tubing for the controlled space
pressure (high) and reference pressure (low) taps, or tag
the tubes.
3. Regardless whether the controlled space is positive or
negative with respect to its reference, locate the high
pressure tap in the controlled space (the setpoint can be
set between -0.2" and 0.2" wc).
4. Locate the reference pressure (low) tap in the area
surrounding the controlled space. Not locating the
reference tap to the sensor results in unsatisfactory
operation.
5. Locate both taps so they are not inuenced by any source
of moving air (velocity pressure). These sources may
include air diffusers or doors between the high and low
pressure areas.
6. Route the building tap tube between the curb and the
supply duct and feed it into the unit through the knockout
in the bottom of the control panel.
7. Connect the tube to the (high) tting for sensor SPS2.

Electrostatic Discharge (ESD)
Disconnect Power to the Rebel Rooftop Unit prior to
inspecting and/or repairing.
When inspecting/repairing Rebel Rooftop units the technician or
building owner must take precautions to ground themselves to
the unit. This will prevent them from damaging the circuit boards
mounted inside the inverter box and main control panel.
Electrostatic Discharge (ESD) can damage components in a
manner that is not always readably detectable. A static potential
can easily be generated on a person that reaches 25 kVolts. If
this potential is discharged into one of the unit’s circuit boards it
can degrade part of the current carrying conductors inside. This
is the conceptual equivalent of reducing 16 gage wires to 18.
The component will still operate initially, but will have a much
shorter life span due to overheating of the conductor.
In order to prevent ESD from the technician to the unit they
must both be at the same potential. First the technician must
ground themselves to the unit; this can be achieved by touching
any galvanized (not painted) section of the unit. The unit’s base
rail and refrigerant piping are both reliable options. The next
step is to attach a grounded wrist or ankle strap to the copper
tubing. This grounding strap must have direct contact with the
technician’s skin. Once this has been done the technician is free
to work on electrical components in side the unit.
Although ESD is partially dependent on humidity, at levels
above 50% it is a greatly reduced risk, good practices should
always be observed.
All Units
Wiring must comply with all applicable codes and ordinances.
The warranty is voided if wiring is not in accordance with these
specications.
According to the National Electrical Code, a disconnecting
means shall be located within sight of and readily accessible
from the air conditioning equipment. The unit can be ordered
with an optional factory mounted disconnect switch. This switch
is not fused. Power leads must be over-current protected at the
point of distribution. The maximum rated overcurrent protection
device (MROPD) value appears on the unit nameplate.
All units are provided with internal power wiring for single point
power connection. The power block or an optional disconnect
switch is located within the main control panel. Field power leads
are brought into the unit through knockouts in the bottom of the
main control panel (see Figure 9 and also Table 5). Refer to the
unit nameplate to determine the number of power connections.
NOTE: To wire entry points, refer to certied drawings for
dimensions.

WARNING
Provide proper line voltage and phase balance.
Improper line voltage or excessive phase imbalance
constitutes product abuse. It can cause severe damage
to the unit’s electrical components.
WARNING
Electrical shock hazard. Can cause severe injury or
death.
Connect only low voltage NEC Class II circuits to
terminal block TB2.
DANGER
Overheating or failure of the gas supply to shut off can
cause equipment damage, severe personal injury or
death. Turn off the manual gas valve to the appliance before
shutting off the electrical supply.
The preferred entrance for power cables is through the bottom
knockouts provided on the unit. If a side entrance is the only
option, a hole may be drilled in the stationary upright.
The minimum circuit ampacity (MCA) is shown on the unit
nameplate. Refer to Table 5 for the recommended number of
power wires.
Copper wire is required for all conductors. Size wires in
accordance with the ampacity tables in Article 310 of the
National Electrical Code. If long wires are required, it may be
necessary to increase the wire size to prevent excessive voltage
drop. Wires should be sized for a maximum of 3% voltage drop.
Supply voltage must not vary by more than 10% of nameplate.
Phase voltage imbalance must not exceed 2%. (Calculate the
average voltage of the three legs. The leg with voltage deviating
the farthest from the average value must not be more than
2% away.) Contact the local power company for correction of
improper voltage or phase imbalance.
The power source to the unit must be a balanced 3-phase power
supply, meaning that the voltage and impedance to the line is
matched. Under normal conditions, a balanced power supply
will result in balanced current phase-to-phase. Unbalanced
voltage and/or current (such as provided with an "Open Delta"
conguration), is likely to result in nuisance alarms, premature
failure of components and it will void equipment warranty.
A ground lug is provided in the control panel. Size the grounding
conductor in accordance with Table 250-95 of the National
Electrical Code.
In compliance with the National Electrical Code, a 115 V factory
mounted service receptacle outlet is provided. This outlet must
be powered by a eld connected 15 A, 115 V power supply.
Leads are brought into the unit through the bottom of the main
control panel.
Field Control Wiring
The Rebel rooftop units are available with the following eld
control connections:
• Space sensor.
• Space sensor with setpoint adjustment.
• Fan operation output.
• VAV box output.
• Remote alarm output.
• External discharge air temperature reset.
• Outdoor air damper minimum position adjustment.
Descriptions of these eld connections are included in the
MicroTech III Unit Controller Manual (OM 1141).
Start-up and service of this equipment must be performed
by trained and experienced technicians. It is highly
recommended that the initial start-up and future service be
performed by Daikin trained technicians who are familiar with
working on live equipment. A representative of the owner or the
operator of the equipment should be present during start-up to
receive instructions in the operation, care and adjustment of
the unit.
Before Start-Up
1. Notify inspectors or representatives who may be required to
be present during start-up of gas fuel equipment. These could
include the gas utility company, city gas inspectors, heating
inspectors, etc.
2. Review the equipment and service literature and become
familiar with the location and purpose of the furnace controls.
Determine where the gas and power can be turned off at the
unit and before the unit.
3. Determine that power is connected to the unit and available.
4. Determine that the gas piping, meter, and service regulator
have been installed, tested, and meet the equipment
requirements.
5. Determine that proper instruments will be available for the
start-up. A proper start-up requires the following: voltmeter,
manometer or gauges with ranges for both manifold pressure
and inlet gas pressure.

Piping System
The Rebel piping system varies signicantly between the
multiple possible congurations; heat pump, cooling only, and
modulating hot gas reheat. In spite of this multiplicity there
are some consistent characteristics. All units have a single
circuit with a single or tandem compressor. All units use
an electronic expansion valve (EVI) and a start-up by pass
solenoid valve (SVB).
