When heaters are installed maintain clearances from combustible materials as specified on unit rating plate. Do not use plastic
lined or combustible flexible ducting within 36
inches of the supply end of the air handler.
Failure to do so can result in fire, property
damage, personal injury and/or death.

GeneralInformation

Installation or repairs made by unqualified persons can
result in hazards to you and others. Installation MUST
conform with local building codes and with the
National Electrical Code NFPA70 current edition.
The information contained in this manual is intended
for use by a qualified service technician familiar with
safety procedures and equipped with the proper tools
and test instruments.
Failure to carefully read and follow all instructions in
this manual can result in equipment malfunction,
property damage, personal injury and/or death.
The blower cabinet may be used for cooling or heat pump operation with or without
electric heat. Installations
without electric
heat, require a No Heat Kit.The cabinet can be installed in an upflow or horizontal
position (Figure
2, 3). Horizontal
installations

require a horizontal
kit. Some models are shipped with the horizontal kit already installed .These units are not shipped with air filters installed.
Filter must be field supplied,
either washable
or
disposal type. Washable
filters are available as an accessory.

Location
Select the best position which suits the installation site conditions.
The location should provide adequate structural support, space in
the front of the unit for service access, clearance
for return air and
supply duct connections,
space for refrigerant piping connections
and condensate
drain line connections.
If heaters
are being
installed make sure adequate
clearance
is maintained
from supply ductwork,
See Clearances
and Warning
in Figure 1.
NOTE: Internal filter can be accessed from separate filter door. If
the filter can NOT be easily accessed,
a remote filter is recommended.
Refer to ACCA Manual D for remote filter sizing.
If the unit is located in an area of high humidity, nuisance sweating
of casing may occur. On these installations
a wrap of 2" fiberglass
insulation
with a vapor barrier should be used.

The open area can be on the front side or a combination
of front

on the sides between cabinet and closet. Refer to ACCA Manual D for sizing and free
area recommendations.

NOTE: Be sure A coil pan fits into the support bracket on the back
side of the cabinet and that pan is under the flange of the bracket
on the right side. The brackets fit over the top edge of the A coil
drain pan to hold it when it's put into the horizontal
position.

NOTE: Local codes may limit application of systems without a
ducted return to single story dwellings.

Horizontal Left and Right Installations
Units that are shipped with the horizontal
drain pan installed are
set up for horizontal
left hand airflow. They must have the drain
pan repositioned

For installation
of the drain pan, refer to the installation
instructions
included with the horizontal

Instructions

CondensateDrain Connections
The unit is provided with 3/4" National Pipe Thread (NPT) condensate drains. (Figure 1). Any drain can be used as a primary or
secondary
drain depending
on the fitting used. Condensate
drain
lines should be installed in a manner that does not obstruct access to the filter.
There is a secondary
drain fitting supplied with the unit that will
convert any of the primary condensate
drain connections
into a
secondary
drain connection.
This fitting should be installed in any
of the primary drain connections
to convert it to a secondary
drain.

2. Install a trap in the drain line below the bottom of the drain
pan and pitch the drain lines down from the coil at least I/4"
per foot of run. Horizontal
runs over 15 feet long must also
have an anti-siphon
air vent (stand pipe), installed ahead
of the horizontal
run. An extremely
long horizontal

require an oversized
drain line to eliminate air trapping.

TemperatureRise Check

For proper system operation, the air flow through the indoor coil
should be between 350 and 450 cfm per ton of cooling capacity.
The air flow through the unit can be determined by measuring the
external static pressure to the unit and selecting the motor speed
tap that will most closely provide the required air flow.
1. Set up to measure external static pressure at the supply
and return duct connections (Figure13).
2. Drill holes in the ducts for pressure taps, pitot tubes, or
other accurate pressure sensing devices.

Condensate Drains
During the cooling season check the condensate
drain lines to be
sure that condensate
is flowing from the primary drain but not
from the secondary
drain. If condensate
ever flows from the
secondary
drain the unit should be promptly
shut off and the
condensate
pan and drains cleaned
to insure a free flowing
primary drain.
