Step 8 — Compressor Crankcase Heater

This compressor has an internal crankcase heater. Furnish power
to the unit a minimum of 24 hours before starting the unit for the

first time.
To furnish power to heater only, set thermostat to OFF and close
electrical disconnect to outdoor unit.
Power is not required to the indoor unit or User Interface for proper
operation of heater.

Crankcase heater will be intelligently

energized as needed between operations, even when the UI or
thermostat and indoor unit is not installed, as long as there is power

to the outdoor unit.

Airflow Setup for Evolution Furnace or FE Fan

Coil (communicating)

This system can only be installed with Evolution--capable indoor
and Evolution Connex User Interface (UI) SYSTXBBECN01,

SYSTXBBECC01 or SYSTXBBECW01 with software version 11
or newer. Version 12 or newer software required on model size 13.

When using an Evolution Connex User Interface, airflow is

automatically selected based on equipment size. The user has the
option of selecting Comfort, Efficiency and Max airflow for

Cooling modes.

These should be selected based on balance

between the homeowner’s comfort and energy consumption

expectations. See User Interface Installation Instructions for

additional available adjustments.
Due to using a communicating control with the fan coil or the

furnace, dip switch adjustments are not necessary. The outdoor
unit configuration and the indoor airflows are determined by

communicating control setup.

Airflow Setup for Non--communicating Fan Coil

The system can be installed with a standard 2--stage thermostat and
FV4C fan coil without additional accessories. Select appropriate

unit size on fan coil Easy select board.

NOTE

: FK4 and 40FK require a TXV change. See accessory list

for approved TXV.

NOTE

: 189BNV13 is AHRI rated with communicating indoor

units only due to low stage airflow requirements.

Airflow Setup for Non--communicating Furnaces

For installations with non--communicating furnaces, set airflows to

350--400 cfm/nominal ton in high stage and 70--80 percent of high
stage airflow in low stage.

Step 9 — Install Accessories

No refrigeration circuit accessories are required or are available for

installation within the unit.

External to the unit, the same

accessories such as support feet, snow rack, wind baffle etc.,
available on other Bryant units, can also be used on this line of

product. For models utilizing 23 inch x 23 inch base pans, it is
recommended to use 5 support feet in order to fully support unit.

See Fig. 8.

Refer to the individual Installation Instructions

packaged with kits or accessories when installing.

Step 10 — Start--Up

CAUTION

!

UNIT OPERATION AND SAFETY HAZARD

Failure to follow this caution may result in minor personal

injury, equipment damage or improper operation.
Observe the following:
1.Do not overcharge system with refrigerant.
2.Do not operate unit in a vacuum or at negative pressure.
3.Do not disable low pressure transducer or system safety

devices such as discharge thermistor or the high pressure
switch.

4.Dome temperatures may be hot.
5.Discharge thermistor is engaged tight on the discharge tube.

CAUTION

!

PERSONAL INJURY HAZARD

Failure to follow this caution may result in personal injury.
Wear safety glasses, protective clothing, and gloves when

handling refrigerant.

CAUTION

!

ENVIRONMENTAL HAZARD

Failure to follow this caution may result in environmental

damage.
Federal regulations require that you do not vent refrigerant to

the atmosphere. Recover during system repair or final unit

disposal.

Follow these steps to properly start up the system:

1. After system is evacuated, close the disconnects to energize

indoor unit, outdoor unit, and User Interface (UI). Do not

attempt to operate the system in heating or cooling mode at

this time. Mode: OFF.

2. Navigate to the service area by pressing MENU from main

screen. Scroll down to service icon and hold until icon

turns green. Once in the Installation and Service menu, se-

lect Refrigerant Charging, then select Charging Cooling.
