The latest safety standards for 38AP
units are certified to UL (Underwriters
Laboratories) and CSA (Canadian
Standards Association) standards, ETL
approved.
Versatility
The 38AP Series condensing units fea-
ture up to 6 compressors and 2 refrig-
erant circuits, and can be matched with
a wide variety of air-handling units.
Single circuit condensing units can op-
erate with a single air handler. Dual cir-
cuit condensing units can operate with
a single air handler or two separate air
handlers. Standard units have multiple
scroll compressors. A digital scroll op-
tion is available. This option of digital
control closely matches building loads
and allows fine incremental adjust-
ments to the variance in load.
Durable construction
All 38AP units have weatherized cabi-
nets constructed of heavy-duty galva-
nized steel prepainted with corrosion-
resistant baked enamel. Inside and out-
side surfaces are protected to ensure
long life and good appearance. The
durable, galvanized steel, prepainted
components exceed the requirements
of the 500-hour salt spray test per
ASTM (American Society for Testing
and Materials) B117.
All 38AP units have Novation®heat
exchangers with microchannel coil
technology. The microchannel heat ex-
changer (MCHX) coils provide long-
term reliability, high performance heat
transfer, and significant savings in re-
frigerant charge. E-coated MCHX is
offered as an option for harsh industri-
al or coastal conditions.
Reliability
The 38AP condensing units feature
highly reliable, hermetic scroll com-
pressors. Each 38AP unit is capable of
unloading in staging sequence of scroll
compressors. Compressors are mount-
ed on rails with vibration isolators to
provide quiet operation and reduced
component stress.
The 38AP units have single or dual
independent circuits; they provide in-
herent backup capability. Each circuit
is also protected by the following safety
features:
• Short-cycle protection
• Low superheat protection
• Loss of refrigerant charge
protection
• Reverse rotation protection
• Suction and discharge pressure
transducers
• High refrigerant pressure switch
(discharge)
• Circuit breakers or fuses for short
circuit protection of compressors
and outdoor fans
• Suction line accumulator for each
refrigerant circuit
Easier installation and service
The 38AP units are equipped with
hinged control-box access doors, con-
trol interface terminal boards, liquid
line shutoff valves, and suction line ser-
vice valves.

To select a 38AP stand-alone condensing unit:
Use Carrier's Commercial Split Builder program to se-
lect a stand-alone outdoor unit from the Installation Config-
uration drop down menu and input the job requirements.
From the list presented, select a 38AP condensing
unit that is estimated to meet capacity requirements.
The 38APS single-circuit unit is offered in sizes 025-065
and the 38APD dual-circuit unit is offered in sizes 025-
130. After a 38AP unit is selected, the program will calcu-
late the condensing unit performance.
To select 38AP systems:
For systems with one 40RU fan coil unit or
39 Series air handler — Use Carrier's Commercial
Split Builder program to select a combined 38AP out-
door unit with matched 40RU indoor unit for sizes 025-
030. The AHUBuilder®selection program is available to
select 38AP outdoor units with a matching 39 Series air
handler with direct-expansion (DX) coils. The 38APS sin-
gle-circuit unit is offered in sizes 025-065 and 38APD
dual-circuit unit is offered in sizes 025-130. Enter the soft-
ware program and input the job requirements. From the
list presented, select a 38AP condensing unit that is esti-
mated to meet capacity requirements. After selecting a
38AP unit, check its performance with one or several DX
coils. From the DX coil list presented on the screen, match
the 38AP with any coil or all coils. The program calculates
the combined performance of the condensing unit and
each DX coil and presents the resulting system capacities
and operating temperatures. Matching thermostatic ex-
pansion valves and nozzles for the DX coils are automati-
cally selected and displayed.
For systems with two air handlers — Use Carrier's
AHUBuilder®selection program to select one size 025-
130 38AP outdoor unit to match with two 39 Series air
handlers with DX coils. For the first air handler, enter the
AHUBuilder selection program and input the job require-
ments. To choose a condensing unit, select the Specify
Your Own option. The program asks for condensing unit
capacities and SDT (saturated discharge temperature) at
30 F ( 1.1 C) and 50 F (10 C) SST (saturated suction tem-
perature). The SDT must first be determined by running a
standalone outdoor unit in the Commercial Split Build-
er program. The circuit capacity is listed in the Condens-
ing Unit Circuit Ratings tables on pages 23-34, 40-51, 57-
68, and 74-85. Enter the capacities from condenser circuit
A or B and SDT for circuits A and B into the AHUBuilder
program. (remember to use the correct air temperature en-
tering condenser column when locating the circuit capaci-
ties). For the second air handler, repeat the procedure to
select the second DX coil for the condenser circuit (A or B)
not used in the first selection.
