WARNING

DO NOT, UNDER ANY CIRCUMSTANCES, CONNECT
RETURN DUCTWORK TO ANY OTHER HEAT-PRODUCING
DEVICE SUCH AS FIREPLACE INSERT, STOVE, ETC.
UNAUTHORIZED USE OF SUCH DEVICES MAY RESULT IN
FIRE, CARBON MONOXIDE POISONING, EXPLOSION,
PERSONAL INJURY, OR PROPERTY DAMAGE.

Location

All models are approved for alcove, closet, and attic installation
in the upflow, downflow or horizontal position.  Refer to the
applicable section of this manual on pages 3-5 for specific
installation instructions on each position.

The air handler must be installed in a level position and should
be located for ease in connecting air duct with proper air
distribution.

Exterior surface of cabinet may sweat when unit is installed in
non-air-conditioned space such as attic or garage. Installer must
provide protection such as full-size auxiliary drain pan on all
units. Be sure to allow for filter access for periodic user servicing.
In addition, caulking must be applied around the power and
control wires entering the control box. This will prevent air
leakage into and condensate from forming inside the control
box.

Clearances

Clearances from the air handler to the combustibles are zero
inches from all sides, top, and bottom; one inch from discharge
air plenum; and the duct within 36 inches of the plenum.

Provide adequate space for servicing the air handler; at least 30
inches. All service and maintenance can be performed from the
front access doors of the air handler.

INTRODUCTION

Models AFPB and Plare designed for flexibility and can be used
for upflow, horizontal or downflow applications. These units
are available for systems of 18,000 through 60,000 BTUH
nominal cooling capacity. Factory authorized electric heater kits
are available in 5 kW through 20 kW sizes. See product
specifications for available accessory kits.

INSPECTION AND UNPACKING

A thorough inspection of the shipping container must be made
immediately upon receiving your unit. Look for any punctures
or openings, and if it appears damage has occurred, note it on

over any recommendations contained herein. If there are no
local codes on the subject, installations shall be made in
accordance with the National Electrical Code (NEC) and
recommendations made by the National Board of Fire
