IMPORTANT
INFORMATION ABOUT
EFFICIENCY AND INDOOR
AIR QUALITY

Central cooling and heating
equipment is only as efficient as the
duct system that carries the cooled or
heated air. To maintain efficiency,
comfort and good indoor air quality, it
is important to have the proper
balance between the air being
supplied to each room and the air
returning to the cooling and heating
equipment.

Proper balance and sealing of the
duct system improves the efficiency
of the heating and air conditioning
system and improves the indoor air
quality of the home by reducing the
amount of airborne pollutants that
enter homes from spaces where the
ductwork and/or equipment is
located. The manufacturer and the
U.S. Environmental Protection
Agency’s ENERGY STAR Program
recommend that central duct systems
be checked by a qualified contractor
for proper balance and sealing.

GENERAL INFORMATION

1. IMPORTANT: If installing the unit
over a finished ceiling or living
area, be certain to install an
auxiliary condensate drain pan
under the entire unit. This
auxiliary drain pan should extend
under any evaporator coil
installed with the air handler and
the open portion of the
condensate drain assembly.

2. IMPORTANT: If using a cooling
evaporator coil with this air
handler:

Be sure the air passes over the
coil/pump before passing over
the cooling coil.

FIGURE 3

IMPORTANT: Support this unit

when installed. Since this air
handler is suitable for attic or
crawl space installations, it may
be installed on combustible wood
flooring or by using support
brackets. See Figure 5.

5. IMPORTANT: If installing in a

utility room, be sure the door
is wide enough to:

a. allow the largest part of the air

handler to pass; or

b. allow any other appliance

(such as a water heater)
to pass.

6. IMPORTANT: This air handler is
not approved or recommended
for installation on its back, with
access doors facing upwards
(see Figure 3).

CLEARANCE ­ACCESSIBILITY

The design of air handlers with input
ratings as listed in the tables under
Figure 4 are certified by UL for the
clearances to combustible materials
shown in inches.

See name/rating plate and clearance
label for specific model number and
clearance information.

Service clearance of at least 24” is
recommended in front of
all air handlers.

NOTE: Use recommended 24”
clearance if accessibility clearances
are greater than fire protection
clearances.

Air handlers are shipped with a
bottom closure panel installed.
When bottom return air is used,
remove the panel by removing the
two screws attaching the panel to
the front base angle.

SITE SELECTION

1. Select a site in the building near
the center of the proposed, or
existing, duct system.

Model Number Nomenclature

(WITH EXAMPLE)

I. Define hot water load for the total

required domestic hot water
usage.

As an example, let’s assume that the
selected Tankless Water Heater for your
whole house solution is the RTG-74 and
your calculated heat gain and heat loss
values are as stated in section II.

II. Determine cooling and heating

requirements at design conditions:

The ACCA’s Manual J Residential Load
Calculation method is the established
trade standard, approved by ANSI, for
the correct siziing and selection of
Heating, Ventilation, Air-Conditioning
and Refrigeration (HVACR) equipment in
residential homes. The most recent
revision is the eight edition, an all­inclusive new approach to ensuring that
Indoor Air Quality (IAQ) systems are as
efficient, safe, and healthy as possible.

Before using the Airflow Performance
Table calculate the total static pressure
required. From the given example, note
the Wet Coil Pressure Drop (selected
from the field supplied Evaporative
Cased Coil Installation Instructions), and
the Filter Pressure Drop. Determine both
static pressures at 1600 CFM:

Wet Coil Pressure Drop . . . .0.3 in. W.C.

(From Coil Manufacturer’s Installation Instructions)

External Static Pressure . . . 0.2 in. W.C.

(Ductwork, etc.)

Filter Pressure Drop . . . .08 in. W.C.

(.08 inches if the included filter is used; refer to

the filter’s manufacturer’s instructions if another

filter is used.)

Total Static Pressure. . . 0.58 in. W.C.

IV. Select unit based on required

cooling capacity airflow:

For an initial selection, choose a unit
size that will provide the required
airflow. Refer to Airflow Performance
Table. Note that at 0.6 ESP (external
static pressure) the
RW1T06A3617NAA unit will deliver
1560 CFM when configured for HIGH
speed.

V. Select heating capacity of unit

to provide the requisite design
condition:

From the Hydronic Air Handler/
Tankless Water Heater, note that the
unit RW1T06A3617NAA, (as selected
above) when matched with the RTG­95 Tankless Water Heater, will
provide 59.2 MBH (59,200 BTU/HR)
at an input water temperature (to Air
Handler) of 150°F.
