When electric heat packages with circuit breakers are

ﬁeld-installed, the circuit breaker may be used as a

disconnecting means in most applications. Reference

the NEC and local codes for disconnect requirements.

If a heater kit is installed:

The B6BM air handler is shipped from the factory without

an electric heater kit installed. If Electric heat is desired,

the H6HK heater kit may be purchased separately and

ﬁeld installed. Determine the correct size heater kit for your

unit by referring to the list below or the units rating label.

A Cabinet ....................................................... 15Kw max

B Cabinet ....................................................... 20Kw max

C Cabinet ....................................................... 30Kw max

1. Connect the 2 wire plug of the air handler to the mating

2 wire plug of the heater kit.

2. Connect the line voltage leads to the circuit breaker or

terminal block provided.

3. Connect the heater kit plug with the mating receptacle

on the air handler control board.

If a heater kit is not installed:

1. Remove the 2 wire plug of the air handler by cutting the

wires and discarding the plug.

2. Strip the ends of the 2 air handler wires and connect

to the line-voltage leads with the 2 wire nuts provided.

Electronic Air Cleaner (EAC)

The unit has an output to power an electronic air cleaner

when the blower is running. This output is rated to 1.0

amp at 208/240V.

Humidiﬁer

The unit has an output to power a humidiﬁer when the

blower is running. This output is rated to 1.0 amp at

208/240V.

Optional Humidistat

(B6EM or B6VM Models Only)

The optional humidistat may be installed in the return air

duct to provide excellent humidity control when needed

and maximum system capacity and energy efﬁciency when

humidity levels are normal. The humidistat senses when

humidity in the return air stream is above a preset level

(ﬁeld adjustable) and sends a signal to the motor to reduce

the airﬂow so that more moisture may be removed until the

humidity level drops. The air handler is pre-programmed

for humidistat operation.

Install the humidistat in the return air duct as directed in

the installation instructions included with the kit. Wire the

humidistat through the low-voltage wire entrance in the

air handler to the control board terminal marked DEHUM.

See Figure 15 (page 24) & Figure 16 (page 24). Wire

the humidistat to close on rise in humidity.

STARTUP & ADJUSTMENTS

WARNING:

The evaporator coil is shipped from the factory

with a nitrogen charge. Use caution when

preparing coils for ﬁeld connections. If repairs

make it necessary for evacuation and charging,

it should only be attempted by qualified,

trained personnel thoroughly familiar with this

equipment. Some local codes require licensed

installation service personnel to service this type

of equipment. Under no circumstances should

the equipment owner attempt to install and/or

service this equipment. Failure to comply with

this warning could result in equipment damage,

personal injury, or death.

Before You Start the Unit

Prior to start-up, complete the following inspections:

√ Verify the unit is level and properly located with adequate

clearances for servicing the unit as shown in Table 1,

(page 4).

√ Check condensate drain line(s) for proper drainage.

√ Verify the surrounding area and top of the unit is free

from obstructions and debris.

√ Check all duct connections. Make sure the duct work

is adequately sealed to prevent air leakage.

√ Check all coil connections for leaks.

√ Verify that the line voltage power leads are securely

connected and the unit is properly grounded. Make sure

all doors are installed before restoring power to the unit

√ Verify the thermostat is wired correctly. Make sure all

low voltage wires are securely connected.

√ Verify the power supply branch circuit overcurrent

protection is sized properly.

√ Verify ﬁlter is properly and securely installed.

IMPORTANT: Before starting the unit, install the initial

charge on units that are factory shipped with a nitrogen

holding charge:

1. Read all installation instructions ﬁrst.

2. Purge the nitrogen holding charge.

3. Evacuate the unit to 350 - 500 microns.

4. Allow the unit to remain under vacuum for at least 30

minutes.
