FEATURES/BENEFITS
One--piece heating and cooling units with low sound levels, easy
installation, low maintenance, and dependable performance.
Puron Environmentally Sound Refrigerant is Carrier’s unique
refrigerant designed to help protect the environment. Puron is an
HFC refrigerant which does not contain chlorine that can harm the
ozone layer. Puron refrigerant is in service in millions of systems
proving highly reliable, environmentally sound performance.
Easy Installation
Factory--assembled package is a compact, fully self--contained,
combination gas heating/electric cooling unit that is prewired,
pre--piped, and pre--charged for minimum installation expense.
These units are available in a variety of standard and optional
High--efficiency design offers SEER (Seasonal Energy Efficiency
Ratios) of 15.0 to 16.0, 12.0 to 12.5 EER, and AFUE (Annual
Fuel Utilization Efficiency) ratings as high as 80.4%.
Energy--saving, direct spark ignition saves gas by operating only
when the room thermostat calls for heating. Standard units are
furnished with natural gas controls. A low--cost field installed kit
for propane conversion is available for all units.
48VGN--A units are dedicated Low NOx units designed for
California installations. These models meet the California
maximum oxides of nitrogen (NOx) emissions requirement of 40
nanograms/joule or less as shipped from the factory and MUST be
installed in California Air Quality Management Districts and
wherever a Low NOx rule exists.
Durable, dependable components
Compressors have two stages of cooling and are designed for high
efficiency. Each compressor is hermetically sealed against
contamination to help promote longer life and dependable
operation. Each compressor also has vibration isolation to provide
quieter operation. All compressors have internal high pressure and
overcurrent protection.
Monoport inshot burners produce precise air--to--gas mixture,
which provides for clean and efficient combustion. The large
monoport on the inshot (or injection type) burners seldom, if ever,
requires cleaning. All gas furnace components are accessible in one
compartment.
Turbo--tubulart heat exchangers are constructed of aluminized
steel for corrosion resistance and optimum heat transfer for
improved efficiency. The tubular design permits hot gases to make
multiple passes across the path of the supply air.
In addition, dimples located on the heat exchanger walls force the
hot gases to stay in close contact with the walls, improving heat
transfer.
Stainless steel heat exchanger available as factory installed option.

48VG -- A
Multi--speed ECM Blower Motor is standard on all 48VG--A
models.
Direct--drive PSC (Permanent Split Capacitor) condenser--fan
motors are designed to help reduce energy consumption and
provide for cooing operation down to 40_F (4.4_C) outdoor
temperature. Motormasterr II low ambient kit is available as a
field--installed accessory.
Thermostatic Expansion Valve -- A hard shutoff, balance port
TXV maintains a constant superheat at the evaporator exit (cooling
cycle) resulting in higher overall system efficiency.
Refrigerant system is designed to provide dependability. Liquid
filter driers 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.
High and Low Pressure Switches provide added reliability for the
compressor.
Indoor and Outdoor coils are computer--designed for optimum
heat transfer and 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.
Low sound ratings ensure a quiet indoor and outdoor
environment with sound ratings as low as 72dBA.
Dehumidification Feature
This unit has independent fan speeds for low stage cooling and
high stage cooling. In addition, 208/230 VAC models have the
field--selectable capability to run an enhanced dehumidification
(’DHUM’) speed on high stage cooling (as low as 320CFM per
ton). Coupled with the improved dehumidification associated with
low stage cooling, the DHUM speed allows for a complete
dehumidification solution independent of cooling stage. 208/230
VAC models also have independent fan speeds for low stage gas
heating and high stage gas heating. The dehumidification control
must open the control circuit on humidity rise above the
dehumidification set point.
NOTE: The enhanced dehumidification feature on high stage
cooling does not support use of an economizer.
Heating
S Reliable direct spark ignition system
S Two--speed PSC inducer motor with ball bearings (208/230 VAC
models)
S Low stage heating delivers 65% of high--stage capacity (208/230
VAC models)
Easy to service cabinets provide easy 3--panel accessibility to
serviceable components during maintenance and installation. The
basepan with integrated drain pan provides easy ground level
installation with mounting pad. A nesting feature ensures a positive
basepan to roof curb seal when the unit is roof mounted. A
convenient 3/4--in. (19.05 mm) wide perimeter flange makes frame
mounting on a rooftop easy.
Standard horizontal metal duct covers with insulation come
with the unit and cover the horizontal duct openings. These can be
left in place if the units are converted to downflow.
Integrated Gas Control (IGC) board provides safe and efficient
control of heating and simplifies trouble--shooting through its
built--in diagnostic function.
Cabinets are constructed of heavyduty, phosphated, zinc--coated
prepainted steel capable of withstanding 500 hours in salt spray.
Interior surfaces of the evaporator/heat exchanger compartment are
insulated with foil--faced insulation, 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 and Air Conditioning Engineers
62.2.) The sloped drain pan minimizes standing water in the drain.
An external drain is provided.
Louvered grille provides hail and vandalism protection for the
coil.

4. Determine fan speed and power requirements at
design conditions.
Given:
Required Cooling Capacity (TC) . . . . . . . . . . 34,000 Btuh
Sensible Heat Capacity (SHC) . . . . . . . . . . . . 25,000 Btuh
Required Heating Capacity . . . . . . . . . . . . . . . 60,000 Btuh
Condenser Entering Air Temperature . . . . . . . 95F (35C)
Indoor--Air Temperature . 80F (26C)edb 67F (19C)ewb
Evaporator Air Quantity . . . . . . . . . . . . . . . . . . 1200 CFM
External Static Pressure . . . . . . . . . . . . . . . . 0.100 IN. W.C.
Electrical Characteristics . . . . . . . . . . . . . . . . . . . 208--1--60
Before entering the air delivery tables, calculate the total static
pressure required. From the given example, the Wet Coil Pressure
Drop Table, and the Filter Pressure Drop Table:
External Static Pressure
0.100 IN. W.C
Filter
0.07 IN. W.C
Wet Coil Pressure Drop
0.180 IN. W.C
Total Static Pressure
0.287 IN. W.C
Enter the table for Dry Coil Air Delivery—Horizontal and
Downflow Discharge. At .287 IN. W.C. ESP, the closest speed to
1200 CFM is Med--Low (pink wire), which delivers 1262 CFM at
.3 in ESP.
2. Select unit based on required cooling capacity.
Enter Net Cooling Capacities table at condenser entering
temperature of 95F (35C). Unit 036 at 1200 cfm and 67F
(19C) ewb (entering wet bulb) will provide a total capacity of
34,200 Btuh and a SHC of 27,400 Btuh. Calculate SHC correction,
if required, using Note 4 under Cooling Capacities tables.
5. Select unit that corresponds to power source
available.
The Electrical Data Table shows that the unit is designed to operate
at 208--1--60.
3. Select heating capacity of unit to provide design
condition requirement.
In the Heating Capacities and Efficiencies table, note that the unit
036090 (208/230 VAC) will provide 74,000 Btuh with an input of
90,000 Btuh in high stage and will provide 47,000 Btuh of heating
in low stage.

Where: hewb = Enthalpy of air entering evaporator coil
4. The SHC is based on 805 F (26.6_C) edb temperature of air entering
evaporator coil. Below 80_F (26.6_C) edb, subtract (corr factor x cfm) from
SHC.
Above 80_ F (26.6_C) 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.

Condensate trap — A 2--in. (50.8 mm) condensate trap must be
field supplied.
Ductwork — Secure downflow discharge ductwork to roof curb.
For horizontal discharge applications, attach ductwork to unit with
flanges.
To convert a unit to downflow discharge — Units are equipped
with factory--installed inserts in the down--flow openings. Removal
of the inserts is similar to removing an electrical knock--out. Use
the duct cover to seal the horizontal discharge openings in the unit.
Units installed in horizontal discharge orientation do not require
duct covers.
Airflow — Units are draw--thru in the cooling mode and
blow--thru in the heating mode.
Maximum cooling airflow — To minimize the possibility of
condensate blow--off from the evaporator, airflow through the units
should not exceed 450 cfm per ton.
Minimum cooling airflow — Minimum cooling airflow is 350
cfm per ton.
Minimum ambient cooling operation temperature — All
standard units have a minimum ambient operating temperature of
40_F (4_C). With accessory low ambient temperature kit, units can
operate at temperatures down to 0_F (--17_C).
Minimum temperature — Air entering the heat exchanger in
heating mode must be a minimum of 55_F (13_C) continuous and
a maximum of 80_F (27_C) continuous.

Operating sequence
208/230 VAC Models:
On a call for low stage heating, terminal W1 on the thermostat is
energized. On a call for high stage heating both terminals W1 and
W2 are energized. Regardless of the stage of the heating call, the
induced--draft motor is turned on to high speed for a 15 sec
pre--purge time. After the pre--purge, when the pressure switch
senses that sufficient combustion air is being moved by the
induced--draft motor, the ignition sequence begins. The IGC will
energize the sparker and the low stage gas valve solenoid. Upon
sensing flame, the IGC will check the heating call. If W2 is not
energized, the IGC will drop the induced--draft motor to low speed
and maintain the gas valve on low stage. If W2 is energized, the
IGC will maintain the induced--draft motor on high speed and
energize the high stage gas valve solenoid. Thirty sec after flame is
sensed the IGC will turn on the evaporator fan motor. If W2 is not
energized, the evaporator fan motor will run on low heat speed. If
W2 is energized, the evaporator fan motor will run on high heat
speed. After the call for heat is satisfied, the IGC will run the
evaporator fan motor an additional field--selectable time of 90, 120,
150, or 180 sec before shutting the evaporator fan motor off.
460 VAC Models:
On a call for heating, terminal W of the thermostat is energized,
starting the induced--draft motor. When the pressure switch senses
that the induced--draft motor is moving sufficient combustion air,
the ignition sequence begins. This function is performed by the
integrated gas unit controller (IGC). The indoor (evaporator)--fan
motor is energized 45 sec after flame is established. When the
thermostat is satisfied and W is de--energized, the burners stop
firing and the indoor (evaporator) fan motor shuts off after a
45--sec time--off delay. Please note that the IGC has the capability
to automatically reduce the indoor fan motor on delay and increase
the indoor fan motor off delay in the event of high duct static
and/or partially--clogged filter.
Cooling — When the system thermostat calls for cooling, 24 V is
supplied to the “Y1/Y” and “G” terminals of the thermostat. This
completes the circuit to the contactor coil (C) and indoor
(evaporator) fan relay (IFR). The normally open contacts of
energized C close and complete the circuit through compressor
motor (COMP) to outdoor (condenser) fan motor (OFM). Both
motors start instantly. The set of normally open contacts of
energized IFR close and complete the circuit through IFM. The
IFM starts instantly.
On the loss of the thermostat call for cooling, 24 V is removed
from both the “Y1/Y” and “G” terminals (provided the fan switch
is in the “AUTO” position) de--energizing the compressor
contactor and opening the contacts supplying power to
compressor/OFM. After a 60--second delay, the IFM shuts off. If
the thermostat fan selector switch is in the “ON” position, the IFM
will run continuously.
NOTE: On units with a Time Guard II device: Once the
compressor has started and then stopped, it cannot be restarted
again until 5 minutes have elapsed.
