unit is ready for installation in either upflow or horizontal 

right-hand air discharge applications. Horizontal drain 

pan may be repositioned in the field to allow installation 

in the horizontal left-hand air discharge position. Various 

accessories are available and listed in the BCE5V Product 

Specification for ordering.

This instruction is intended as a general guide and does 

not supersede local or national codes in any way. Consult 

authorities having jurisdiction before installation. 

NOTE: 

Special  procedures  are  required  for  cleaning 

the  Omniguard

TM

  coil  in  this  unit.  See  Page  22  in  this 

instruction for information. 

Requirements

Excessive  Weight  Hazard  -  Use  two  or  more  people 

when  moving  and  installing  the  unit.  Failure  to  do  so 

can result in back or other type of injury.

 WARNING

BCE5V 

units  include  a  factory-installed  check/

expansion valve which will provide optimal refrigerant 

control and system performance with outdoor units of 

varying capacities. These units must be installed as 

a part of a matched system as outlined in the BCE5V 

Product Specification.

 IMPORTANT

These instructions are intended as a general guide. 

Compliance  with  all  local,  state,  or  national  codes 

pertaining to this type of equipment should be determined 

prior to installation. Read this instruction manual, as well 

as the instructions supplied in separate equipment, before 

starting the installation. 

In addition to conforming to manufacturer’s installation 

instructions and local municipal building codes, installation 

of air handler units (with or without optional electric heat), 

MUST  conform  with  National  Fire  Protection Association 

(NFPA) standards: “Standard for Installation of Air 

Conditioning and Ventilation Systems” (NFPA No. 90A) 

and “Standard for Installation of Residence Type Warm Air 

Heating and Air Conditioning Systems” (NFPA No. 90B). 

All models are designed for indoor installation only. The 

installation of the air handler, field wiring, duct system, etc. 

must conform to the requirements of the National Electrical 

Code,  ANSI/NFPA  No.  70  (latest  edition)  in  the  United 

States, and any state laws, and local ordinances (including 

plumbing or waste water codes). 

Local authorities having jurisdiction should be consulted 

before installation is made. Such applicable regulations 

or requirements take precedence over the general 

instructions in this manual. 

Install  the  conditioned  air  plenum,  ducts  and  air  filters 

(provided)  in  accordance  with  NFPA  90B  Standard  for 

the Installation of Warm Air Heating and Air-Conditioning 

Systems (latest edition). 

The air handler is shipped from the factory completely 

assembled.  The  unit  is  provided  with  flanges  for  the 

connection of the duct system. 

Do not remove the cabinet knockouts until it has been 

determined which knockouts will need to be removed for 

the installation. 

Select the air discharge position which best suits the site 

conditions. Consider required clearances, space, routing 

requirements for refrigerant line, condensate disposal, 

filters,  duct  system,  wiring,  and  accessibility  for  service. 

Refer  to  the  rating  plate  on  the  air  handler  for  specific 

information.

Danger  of  explosion.  Keep  flammable 

materials and vapors, such as gasoline, 

away from air handler. Place air handler so 

that heating elements are at least 18 inches 

(46  cm)  above  the  floor  for  a  garage 

installation.  Failure  to  follow  these 

instructions can result in death, explosion, 

or fire.
