Product Data
The 38YCC Outdoor Section of Split--System Heat Pumps is
designed for quiet, reliable heating during the winter and cooling
during the summer. With EER ratings up to 9.0, this heat pump
system provides economy of operation through energy
conservation when used with components designated by Carrier.
The 38YCC recovers heat for indoor comfort from outdoor air
during the heating season and, by automatically reversing the
refrigerant system, removes indoor heat and excess humidity
during the cooling season.
FEATURES AND BENEFITS
Electrical Range
Single--phase units are available in sizes 018, 024, and 036 in 230v
50 Hz. Three--phase units are available in sizes 036, 048, and 060
in 400v 50 Hz.
Wide Range of Sizes
The 38YCC is available in nominal sizes 018, 024, 036, 048 and
060 to meet the needs of residential and light commercial
applications.
Unit Design
All units are equipped with totally enclosed fan motors for greater
reliability under adverse weather conditions. The large,
wrap--around coil uses copper tube and enhanced epoxy coated
aluminum fin and is designed for optimum heat transfer and
corrosion protection during heating and cooling. The vertical air
discharge carries the sound and air up and away from adjacent
patio areas and foliage. Coil can be cleaned with a common garden
hose.
Weather--Protective Cabinet
A weather protective cabinet of pre--painted steel is protected
underneath by a zinc galvanized coating for a finish that will last
for many years. All screws on cabinet exterior are coated for a
long--lasting, rust--resistant, quality appearance.
Compressor
Designed specifically for heat pump duty, with energy efficiency
during heating and cooling operation. The compressor is
hermetically sealed against contamination to assure long life and
dependable performance, internally sprung (units with
reciprocating compressor), and externally mounted on rubber
isolators for quiet operation. For improved serviceability, all
models are equipped with a compressor terminal plug.
Compressor Protection
Each compressor is protected with internal temperature-- and
current--sensitive overloads.
Reliable standard components
Includes a suction--tube accumulator that reduces the amount of
liquid refrigerant that reaches the compressor; a high pressure
switch to prevent excessive pressure build--up; a low--pressure
switch to stop the compressor if refrigerant charge is lost; a
crankcase heater to keep compressor oil warm and free of
refrigerant for maximum lubricity; an internal compressor relief
valve for high--pressure protection; and 5--minute compressor
delay.
3--phase monitor board (scroll compressor models)
Control board that monitors the electrical phase and prevents
compressor operation if wired incorrectly. Standard on 048 and
060 3 phase equipment.

FEATURES AND BENEFITS (CONT.)
External Service Valves
Service valves are brass, front seating type. The 38YCC has sweat
field connections. Valves are externally located so refrigerant tube
connections can be made quickly and easily. Each valve has a
service port for ease of checking operating refrigerant pressures.
Easy Serviceability
One panel provides access to electrical controls. Removal of wire
dome gives access to fan motor and removal of the top gives access
to the coil and compressor. All models are equipped with a
compressor terminal plug.
Discharge Muffler
Minimizes low frequency sound and pressure pulsation generated
by compressor discharge gas.
Defrost Control Board
This board incorporates a built--in 5--minute compressor
time--delay relay, defrost relay, defrost timer, and low--voltage
terminal board. The defrost control is a time/temperature initiation/
termination control which includes 4 field--selectable (DIP switch)
time periods of 30, 60, 90, and 120 minutes. This control also
includes a field selectable (DIP Switch) Quiet Shift defrost mode
which, if selected, maintains extremely quiet operation during
defrost.

NOTE: When the required data falls between the published data, interpolation may be performed. Extrapolation is not an acceptable practice. * Detailed cooling capacities are based on indoor and outdoor unit at the same elevation and connected by 4.55 m of tubing. If other than 4.55 m of tubing is used and/or indoor unit is located above outdoor unit, a slight variation
in capacity may occur.
{Total and sensible capacities are net capacities. Blower motor heat has been subtracted. }Sensible capacities shown are based on 27˚C entering air at the indoor coil. For sensible capacities at other than 27˚C, deduct 245 kW per 480 L/S of indoor coil air for each degree below 27˚C, or add 245 kW per 480 L/S of
indoor coil air per degree above 27˚C.
** System kW is total of indoor and outdoor unit kilowatts. EWB --- Entering Wet Bulb

NOTE: When the required data fall between the published data, interpolation may be performed. Extrapolation is not an acceptable practice. * Detailed cooling capacities are based on indoor and outdoor unit at the same elevation per ARI standard 210/240 ---94. If additional tubing length and/or indoor unit is located above outdoor unit, a slight variation in capacity may
occur.
{Total and sensible capacities are net capacities. Blower motor heat has been subtracted. }Sensible capacities shown are based on 80˚F(27˚C) entering air at the indoor coil. For sensible capacities at other than 80˚F(27˚C), deduct 835 Btuh (245 kW) per 1000 CFM (480 L/S) of indoor coil air for each degree below
80˚F(27˚C), or add 835 Btuh (245 kW) per 1000 CFM (480 L/S) of indoor coil air per degree above 80˚F(27˚C).
** Unit kW is total of indoor and outdoor unit kilowatts. EWB --- Entering Wet Bulb

NOTE: When the required data falls between the published data, interpolation may be performed. Extrapolation is not an acceptable practice. * The kW values include the compressor, outdoor fan motor, and indoor blower motor. The kw from supplement heaters should be added to these values to obtain total system kilowatts. {The kW heating capacity values shown are net integrated values from which the defrost effect has been subtracted. The kW heating from supplement heaters should be added to those values to obtain total system capacity. EDB --- E n t e r i n g D r y B u l b
