FEATURES/BENEFITS
One-piece heat pump with optional electric heater, low
installation cost, dependable performance and easy
maintenance.
EFFICIENT OPERATION
Energy Efficient design with SEERs (Seasonal Energy
Efficiency Ratios) of 10.0 and HSPFs (Heating Seasonal
Performance Factors) of up to 7.0
EASY INSTALLATION
Factory-assembled package is a compact, fully self-contained,
heat pump unit that is pre-wired, pre-piped, and pre-charged for
minimum installation expense. 601A units are available in a
variety of standard capacity ranges with voltage options to meet
residential and light commercial requirements. Units install
easily on a rooftop or at ground-level.
DURABLE, DEPENDABLE COMPONENTS
Compressors are designed for energy efficiency. Each
compressor is hermetically sealed against contamination to help
promote longer life and dependable operation. Vibration
isolation provides quiet operation. Compressors have internal
high-pressure and overcurrent protection.
Convertible duct configuration Unit is designed for easy use
in either downflow or horizontal applications. Each unit is easily
converted from horizontal to downflow, and includes horizontal
duct covers.
Direct-drive multi-speed, PSC (permanent split capacitor)
blower motor is standard on all 601A models.
Direct-drive, PSC condenser-fan motors are designed to help
reduce energy consumption and provide for cooling operation
down to 40°F outdoor temperature. Motormaster® II low ambient
kit is available as a field-installed accessory and does not require
a special motor.
Corporate thermostats work with Bryant’s small packaged
products as a system to promote year round comfort.
Refrigerant system is designed to provide dependability. Liquid
refrigerant strainers are used to promote clean, unrestricted
operation. Each unit leaves the factory with a full refrigerant charge.
Refrigerant service connections make checking operating
pressures easier.
Indoor and outdoor coils are computer-designed for optimum
heat transfer and cooling efficiency. The indoor coil is fabricated
from copper tube and aluminum fins and is located inside the unit
for protection against damage. The outdoor coil is internally
mounted on the top tier of the unit. A FIOP (Factory-Installed
Option) metal louvered grille is available on all models. Copper fin
coils and pre-coated fin coils are available from the factory by
special order. These coils are recommended in applications
where aluminum fins are likely to be damaged due to corrosion.
They are ideal for seacoast applications.
Low sound ratings ensure a quiet indoor and outdoor
environment with sound ratings as low as 73 dB.
(See page 3.)
Easy to service cabinets provide easy single-panel accessibility
to serviceable components during maintenance and installation.
The unit base with integrated drain provides easy ground level
installation with or without a mounting pad. Convenient handholds
are provided to manipulate the unit on the jobsite. A nesting
feature ensures a positive unit base to roof curb seal when the unit
is roof mounted. A convenient 3/4-in. wide perimeter flange makes
frame mounting on a rooftop easy.
Downflow operation is easily provided in the field to allow
vertical ductwork connections. The unit base utilizes knockout
style seals on the bottom openings to ensure a positive seal in the
horizontal airflow mode.
Cabinets are constructed of heavy-duty, phosphated, zinc-coated
prepainted steel capable of withstanding 500 hours of salt spray.
Interior surfaces are insulated with cleanable semi-rigid insulation
board, which keeps the conditioned air from being affected by the
outdoor ambient temperature and provides improved indoor air
quality. (Conforms to American Society of Heating, Refrigeration
1-1/2 To 5 Nominal Tons
Form No. PDS 601A.18.3
and Air Conditioning Engineers No. 62P.) The sloped drain
minimizes standing water in the drain, which is provided with an
external drain fitting.
Standard metal duct covers with insulation come with the unit
and cover the duct openings. These can be left in place if the units
are converted to downshot.
Short-Cycling protection (TimeGuard® II Logic) for the
compressor is incorporated into our defrost control board
ensuring a five minute delay (+/-2 minutes) before restarting
compressor after shutdown for any reason.

SELECTION PROCEDURE (WITH EXAMPLE)
I Determine cooling and heating requirements at design
conditions:
Given:
Required Cooling Capacity (TC) . . . . . . . . . . 28,000 Btuh
Sensible Heat Capacity (SHC) . . . . . . . . . . . . 20,500 Btuh
Required Heating Capacity . . . . . . . . . . . . . . 28,550 Btuh
Outdoor Entering Air Temperature . . . . . . . . . . . . . . . 95°F
Outdoor-Air Winter Design Temperature . . . . . . . . . . 20°F
Indoor-Air Winter Design Temperature . . . . . . . . . . . 70°F
Indoor Entering-Air Temperature . . . . . . . . . . . . .80°F edb
67°F ewb
Indoor-Air Quantity . . . . . . . . . . . . . . . . . . . . . . . .1125 cfm
External Static Pressure. . . . . . . . . . . . . . . . . . 0.30 in. wg
Electrical Characteristics (V-Ph-Hz) . . . . . . . . . . . 230-1-60
edb — entering dry bulb
ewb — entering wet bulb
II Select unit based on required cooling capacity.
Enter Cooling Capacities table at outdoor entering-air
temperature of 95°F, indoor air entering at 1125 cfm and
67°F ewb (entering wet bulb). The 030 unit will provide a
total cooling capacity of 29,100 Btuh and a sensible heat
capacity of 22,900 Btuh.
For indoor-air temperature other than 80°F edb (entering dry
bulb), calculate sensible heat capacity correction, as
required, using the formula found in Note 3 following the
cooling capacities tables. NOTE: Unit ratings are net
capacities.
III Select electric heat.
Enter the 030 unit Heating Capacities table at 1125 cfm. At
70°F return indoor air and 20°F air entering outdoor coil, the
integrated heating capacity is 15,030 Btuh. (Select
integrated heating capacity value since deductions for
outdoor-coil frost and defrosting have already been made.
No correction is required.)
The required heating capacity is 28,550 Btuh. Therefore,
13,520 Btuh (28,550 – 15,030) additional electric heat is
required.
Determine additional electric heat capacity in kW.
13,520 Btuh
3414 Btuh/kW
Enter the Electric Heater table on page 5 for 208/230 v,
single-phase, unit. The 5-kW heater at 240 v most closely
satisfies the heating required. To calculate kW at 230 v,
multiply the heater kW by multiplication factor 0.92 found in
the Multiplication Factors table on page 18.
5 kW x 0.92 = 4.6 kW
4.6 kW x 3414 = 15,704 Btuh
Total unit heating capacity is 30,734 Btuh (15,030 + 15,704).
IV Determine fan speed and power requirements at design
conditions.
Before entering the air delivery tables, calculate the total
static pressure required.
= 3.96 kW of heat required

NOTES:
1. Ratings are net; they account for the effects of the evaporator-fan motor power
and heat.
2. Direct interpolation is permissible. Do not extrapolate.
3. The following formulas may be used:
t=t
ldb edb
t = Wet-bulb temperature corresponding to enthalpy of air leaving
lwb
evaporator coil (h )
h=h
lwb ewb
Where: h = Enthalpy of air entering evaporator coil
4. The SHC is based on 80 F edb temperature of air entering evaporator coil.
Below 80 F edb, subtract (corr factor x cfm) from SHC.
Above 80 F edb, add (corr factor x cfm) to SHC.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).
5. Integrated capacity is maximum (instantaneous) capacity less the effect of frost
on the outdoor coil and the heat required to defrost it.

CONTROLS
SEQUENCE OF OPERATION
When power is supplied to unit, the transformer (TRAN) is
energized.
On units with crankcase heater, heater is also energized.
Cooling — With the thermostat subbase in the cooling position,
the thermostat makes circuit R-O. This energizes the reversing
valve solenoid (RVS) and places the unit in standby condition for
cooling.
As the space temperature rises, the thermostat makes, closing
circuit R-Y. A circuit is made to contactor (C), starting the
compressor (COMP) and outdoor-fan motor (OFM). Circuit R-G
is made at the same time, energizing the indoor-fan relay (IFR)
and starting the indoor-fan motor (IFM) after a 1-second delay.
When the thermostat is satisfied, contacts open, deenergizing C.
The COMP and OFM stop, and the IFM stops after a 60 second
time delay.
Heating — On a call for heat, thermostat makes circuits R-Y
and R-G.
A circuit is made to C, starting COMP and OFM. Circuit R-G also
is completed, energizing IFR and starting IFM after a 1-second
delay.
Should room temperature continue to fall, circuit R-W is made
through second-stage thermostat bulb. If optional electric heat
package is used, a relay is energized, bringing on first bank of
supplemental electric heat. When thermostat is satisfied,
contacts open, deenergizing contactor and relay; motors and
heaters deenergize. The IFM is controlled by a time-delay relay
that keeps the fan on for 60 seconds.
Defrost — Defrost board (DB) is a time and temperature control,
which includes a field-selectable time period between checks for
defrost (30, 50, and 90 minutes). Electronic timer and defrost
cycle start only when contactor is energized and defrost
thermostat (DFT) is closed.
Defrost mode is identical to cooling mode, except outdoor fan
motor stops and a bank of optional electric heat turns on to warm
air supplying the conditioned space.
NOTES:
1. Compressor time delay occurs through the defrost control
board.
2. Defrost control board has built in 5 minute compressor delay:
once the compressor has started and then stopped, it cannot be
restarted again until 5 minutes have elapsed.
