HEAT PUMP UNITS

UNIT 601A

Single-Packaged Heat Pump for Residential and Light Commercial Applications

• Low Sound Levels

• 10 SEER

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.

OPTIONS AND ACCESSORIES

Factory-installed options

Louvered grille provides hail and vandalism protection. A wire grille is standard on all models. See model number nomenclature for louvered grille options.

Coil options include copper/copper and vinyl-coated

construction for refrigerant coils. Units are shipped standard with copper tube/aluminum ﬁn construction. See model number nomenclature for coil options.

Field-installed accessories

Economizer with Solid-State Controls and Barometric Relief Dampers Manual Air Damper (25% open) Electric Heaters Filter Rack Flat Roof Curbs (8-in. and 14-in.) Square-to-Round Duct Transition Kit Thermostats Controls Upgrade Kit Crankcase Heater Rigging Kit Low Ambient Kit (Motormaster® II Control) Solid-State Time Guard® II Device Compressor Hard Start Kit

Economizer with solid-state controls and barometric relief dampers includes ﬁlter racks and provide outdoor air during

cooling and reduce compressor operation.

Manual outside air damper includes hood and ﬁlter rack with

adjustable damper blade for up to 25% outdoor air.

Electric heaters provide additional heat in the unit when

required. Each package has a heater module that slides into the controls compartment. Heater sizes range from 5.0 to 20.0 kW. The electric heater design allows the use of a single-point power supply for the entire unit, resulting in lower installed costs.

Flat roof curbs in both 8 in. and 14 in. sizes are available for roof

mounted applications.

Square-to-round duct transition kit enables 018-048 size

units to be ﬁtted to 14 in. round ductwork.

Thermostats provide control for the system heating and cooling

functions. Thermostat models are available in both programmable and non-programmable versions.

Controls upgrade kit supplies high and low pressure safety

protection and protects the unit from operating in unsuitable conditions.

Crankcase heater provides anti-ﬂoodback protection for low-

load cooling applications.

Rigging kit includes lifting brackets which are inserted into the

unit base rigging holds to rig unit for rooftop applications.

Low-ambient kit (Motormaster II control) allows the use of

mechanical cooling down to outdoor temperatures as low as 0°F.

Filter rack features easy installation, serviceability, and high-

ﬁltering performance for vertical and horizontal applications.

Compressor Hard Start Kit gives a boost to the compressor

motor at each start-up.
