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. The most important advantage of Puron refrigerant is
that it has not been banned in future air conditioning systems as the
traditional refrigerant R--22 has been. 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
heating/ cooling size combinations with voltage options to meet
residential and light commercial requirements. Units are
lightweight and install easily on a rooftop or at ground level. The
high tech composite base eliminates rust problems associated with
ground level applications.
Innovative Unit Base Design
On the inside a high--tech composite material will not rust and
incorporates a sloped drain pan which improves drainage and helps
inhibit mold, algae and bacterial growth. On the outside metal base
rails provide added stability as well as easier handling and rigging.
Convertible duct configuration
Unit is designed for use in either downflow or horizontal
applications. Each unit is converted from horizontal to downflow
and includes two horizontal duct covers. Downflow operation is
provided in the field to allow vertical ductwork connections. The
basepan seals on the bottom openings to ensure a positive seal in
the vertical airflow mode.
Efficient operation High--efficiency design
offers SEER
(Seasonal Energy Efficiency Ratios) of 14.2 to 14.5, 12.0 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.
48VLN--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 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
t 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.
ECM Motor is standard on all 48VL--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
1
48VL-- A
temperature. Motormasterr II low ambient kit is available as a
field--installed accessory.
Thermostat controls
Time Guardr
II anti--short cycle protection circuitry. If a
non--corporate thermostat without anti--short cycle protection is
used the Time Guard II field--installed anti--short cycle kit is
recommended.
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. 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 72dBA.
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 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 and
Air
Conditioning Engineers 62.2.) The sloped drain pan minimizes
standing water in the drain. An external drain is provided.

SELECTION PROCEDURE (WITH EXAMPLE)
1. Determine cooling and heating requirements at
design conditions:
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 . . . . . . . 95qF (35qC)
Indoor--Air Temperature . 80qF (26qC)edb 67qF (19qC)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.
48VL-- A
2. Select unit based on required cooling capacity.
Enter Net Cooling Capacities table at condenser entering
temperature of 95qF (35qC). Unit 036 at 1200 cfm and 67qF
(19qC) 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 will provide 72,000 Btuh with an input of 90,000 Btuh.

Where: hewb = Enthalpy of air entering evaporator coil
4. The SHC is based on 80_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.

COOLING 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:
* At 75qF (24qC) entering dry bulb---Tennessee Valley Authority (TVA) rating conditions; all others at 80qF dry bulb.

*In the U.S.A., the input rating for altitudes above 2000 ft (610m) must be reduced by 4% for each 1000 ft (305 m) above sea level.
In Canada, the input rating for altitudes from 2001 to 4500 ft (611 to 1372 m) above sea level must be derated by 10% by an authorized gas conversion station or
dealer.
For Canadian Installations from 2000 to 4500 ft, use U.S.A. column 2001 to 3000 ft.
Note: Orifice sizes and manifold pressure settings are based on natural gas with a heating value of 1025 Btu/ft3 and a specific gravity of .6.

*Air delivery values are without air filter and are for dry coil (See 48VL ---A Wet Coil Pressure Drop table).
1 Factory-shipped heating speed
2 Factory-shipped cooling speed
”NA” = Not allowed for heating speed
Note: Deduct field-supplied air filter pressure drop and wet coil pressure drop to obtain external static pressure available for ducting.
Shaded areas indicate speed/static combinations that are not permitted for dehumidification speed.
Note: Deduct 10% for 208 volt operation.

APPLICATION DATA
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 50_F (10_C) continuous
and/or 45_F (7_C) intermittent.
48VL-- A
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.

CONTROLS
Operating sequence
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 90--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.
48VL-- A
Heating -- 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 burner 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.
