Product Data

®

the environmentally sound refrigerant

Bryant’s Air Conditioners with Puronr refrigerant provide a
collection of features unmatched by any other family of
equipment. The 186B has been designed utilizing Bryant’s Puron
refrigerant. The environmentally sound refrigerant allows you to
make a responsible decision in the protection of the earth’s ozone
layer.

This product has been designed and manufactured to meet
Energy Starr criteria for energy efficiency when matched with
appropriate coil components. Refer to the combination ratings in
the Product Data for system combinations that meet Energy Starr
guidelines.

NOTE: Ratings contained in this document are subject to
change at any time. Always refer to the AHRI directory
(www.ahridirectory.org) for the most up--to--date ratings
information.

REFRIGERANT CHARGE ADJUSTMENTS

Liquid Line Size Puron Charge oz/ft (g/m)

3/8

5/16 0.40 (11.83)

1/4 0.27 (7.98)

(Factory charge for lineset = 9 oz / 266.16 g)

0.60 (17.74)

Units are factory charged for 15 ft (4.6 m) of 3/8” liquid line. The factory charge for 3/8” lineset 9 oz. When using other length or diameter
liquid lines, charge adjustments are required per the chart above.

Charging

Formula:

[(Lineset oz/ft x total length) – (factory charge for lineset)] = charge adjustment
Example 1: System has 15 ft of line set using existing 1/4“ liquid line. What charge adjustment is required?

Formula: (.27 oz/ft x 15ft) – (9 oz) = (-4.95) oz.
Net result is to remove 4.95 oz of refrigerant from the system

Example 2: System has 45 ft of existing 5/16” liquid line. What is the charge adjustment?

Formula: (.40 oz/ft. x 45ft) – (9 oz.) = 9 oz.
Net result is to add 9 oz of refrigerant to the system

LONG LINE APPLICATIONS

An application is considered Long Line, when the refrigerant level in the system requires the use of accessories to maintain acceptable

186B

refrigerant management for systems reliability. See Accessory Usage Guideline table for required accessories. Defining a system as long line
depends on the liquid line diameter, actual length of the tubing, and vertical separation between the indoor and outdoor units.

For Air Conditioner systems, the chart below shows when an application is considered Long Line.

Accessory Description and Usage (Listed Alphabetically)

1. Compressor Start Assist -- Capacitor and Relay

Start capacitor and relay gives a ”hard” boost to compressor
motor at each start up.

Usage Guideline:
Required for reciprocating compressors in the

following applications:

Long line
Low ambient cooling
Hard shut off expansion valve on indoor coil
Liquid line solenoid on indoor coil

Required for single--phase scroll compressors in the
following applications:

Long line
Low ambient cooling

Suggested for all compressors in areas with a history of
low voltage problems.

2. Compressor Start Assist — PTC Type

Solid state electrical device which gives a ”soft” boost to the

186B

compressor at each start--up.

Usage Guideline:

Suggested in installations with marginal power supply.

3. Crankcase Heater

An electric resistance heater which mounts to the base of the
compressor to keep the lubricant warm during off cycles.
Improves compressor lubrication on restart and minimizes the
chance of liquid slugging.

Usage Guideline:

Required in low ambient cooling applications.
Required in long line applications.
Suggested in all commercial applications.

4. Cycle Protector

The cycle protector is designed to prevent compressor short
cycling. This control provides an approximate 5--minute delay
after power to the compressor has been interrupted for any
reason, including power outage, protector control trip, thermostat
jiggling, or normal cycling.

5. Evaporator Freeze Thermostat

An SPST temperature--actuated switch that stops unit operation
when evaporator reaches freeze--up conditions.

Usage Guideline:

Required when low ambient kit has been added.

6. Low--Ambient Pressure Switch Kit

A long life pressure switch which is mounted to outdoor unit
service valve. It is designed to cycle the outdoor fan motor in
order to maintain head pressure within normal operating limits
(approximately 100 psig to 225 psig). The control will maintain
working head pressure at low--ambient temperatures down to 0_F
(--18_C) when properly installed.

Usage Guideline:

A Low--Ambient Pressure Switch or MotorMasterr
Low--Ambient Controller must be used when cooling operation is
used at outdoor temperatures below 55_F (12.8_C).

7. Outdoor Air Temperature Sensor

Designed for use with Bryant Thermostats listed in this
publication. This device enables the thermostat to display the
outdoor temperature. This device also

is required to enable special thermostat features such as auxiliary
heat lock out.

Usage Guideline:

Suggested for all Bryant thermostats listed in this
publication.

8. Support Feet

Four stick--on plastic feet that raise the unit 4 in. (101.6 mm)
above the mounting pad. This allows sand, dirt, and other debris
to be flushed from the unit base, minimizing corrosion.

Usage Guideline:
Suggested in the following applications:
Coastal installations.
Windy areas or where debris is normally circulating.
Rooftop installations.
For improved sound ratings.

9. Thermostatic Expansion Valve (TXV)

A modulating flow--control valve which meters refrigerant liquid
flow rate into the evaporator in response to the superheat of the
refrigerant gas leaving the evaporator.

Kit includes valve, adapter tubes, and external equalizer tube.
Hard shut off types are available.

NOTE: When using a hard shut off TXV with single phase
reciprocating compressors, a Compressor Start Assist Capacitor
and Relay is required.

Usage Guideline:

Required to achieve AHRI ratings in certain equipment
combinations. Refer to combination ratings.

Hard shut off TXV or LLS required in air conditioner
long line applications.

Required for use on all zoning systems.

10. Time--Delay Relay

An SPST delay relay which briefly continues operation of indoor
blower motor to provide additional cooling after the compressor
cycles off.

NOTE: Most indoor unit controls include this feature. For those
that do not, use the guideline below.

Usage Guideline:

For improved efficiency ratings for certain
combinations of indoor and outdoor units. Refer to
AHRI Unitary Directory.

12. Winter Start Control

This control is designed to alleviate nuisance opening of the
low--pressure switch by bypassing it for the first 3 minutes of
operation.
