Fantrol
The Fantrol, provided on all units, is a method of head
pressure control that automatically cycles the condenser fans
in response to ambient air temperature. This feature maintains
head pressure and allows the unit to run at low ambient air
temperatures.
Units have two independent refrigerant circuits with one to four
condenser fans being controlled independently by the ambient
air temperature of each circuit. See the following sections for
sequence of operation for condenser fans with Fantrol.

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.
NOTE: Low head pressure may lead to poor, erratic refrigerant
feed control at the thermostatic expansion valve. The
units have automatic control of the condenser fans
which should provide adequate head pressure control
down to 50°F (10°C) provided the unit is not exposed to
windy conditions. The system designer is responsible
for assuring the condensing section is not exposed to
excessive wind or air recirculation.
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.
Unit Clearances
Service Clearance
Allow service clearance approximately as indicated in Figure
17. Also, Daikin recommends providing a roof walkway to
the rooftop unit as well as along at least the two sides of the
unit that provide access to most controls and serviceable
components.
Figure 17: Service Clearances

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 will 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 “Service Clearance” and
Figure 17 on page 15.
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" (2438mm) on all sides of the unit.
3. The distance between any two units within the walls
should be at least 120" (3048mm).
Do not locate outside air intakes near exhaust vents or other
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 18). This is particularly
important to prevent blowing snow from entering outside air
intake and 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.
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 (see Figure
18):
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 wallboard
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.
Integral supply and return air duct anges are provided with
the roof curb, allowing connection of duct work to the curb
before the unit is set. The gasketed top surface of the duct
anges seals against the unit when it is set on the curb. These
anges must not support the total weight of the ductwork.
See “Installing Ductwork” on page 26 for details on duct
connections. It is critical that the condensate drain side of the
unit be no higher than the opposite side.
Assembly of a typical roof curb is shown in Figure 19 on page
18. Parts Athrough Kare common to all units having bottom
supply and return openings. Depending on the unit length,
Parts Land M may be included with the roof curb kit to create
the correct overall curb length.
Assembly Instructions (Figure 19 on page 18)
1. Set curbing parts A through K per dimensions shown
over roof opening or on a level surface. Note location of
return and supply air openings.
2. If applicable, set other curbing parts (D, L, M, etc.) in
place making sure that the orientation complies with the
assembly instructions. Check alignment of all mating bolt
holes. See Detail A.
3. Bolt curbing parts together using fasteners provided.
Tighten all bolts nger tight.
4. Square entire curbing assembly and securely tighten all
bolts.
5. Position curb assembly over roof openings. Curb must
be level from side to side and over its length. Check that
top surface of the curb is at with no bowing or sagging.
6. Weld curbing in place. Caulk all seams watertight.
Remove backing from 0.25" (6 mm) thick × 1.50" (38
mm) wide gasketing and apply to surfaces shown by
cross-hatching.
7. Flash curbing into roof as shown in Detail B.
8. Parts Eand Fare not required on units with no return
shaft within the curb perimeter.
9. Parts Gand H are not required on units with no supply
shaft within the curb perimeter.
10. Be sure that electrical connections are coordinated (see
Figure 20 on page 19).

of the unit as shown in Figure 21, assuring the I-beam is well
supported by the structural member.
If resilient material is placed between the unit and the rail, insert
a heavy steel plate between the unit and the resilient material to
distribute the load. Seal cabinet penetrations (electrical, piping,
etc.) properly to protect against moisture and weather.

Rigging and Handling
WARNING
Use all lifting points. Improper lifting can cause severe personal injury and
property damage.
Lifting brackets with 2" (51 mm) diameter holes are provided
on the sides of the unit.
Use spreader bars, 96" to 100" (2438 to 2540 mm) wide 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. If there are isolation dampers, make sure they are
properly installed and fully closed to prevent the entry
of animals and debris through the supply and return air
openings.
7. Cover the supply and return air openings on units without
isolation dampers.
