SAFETY
CONSIDERATIONS
Installation and sel-,Ticingof air-conditioning equipment can
be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should
install, repair, or service ai>conditioning equipment.
Untrained personnel can perform basic maintenance functions of cleaning coils and filters and replacing filters. All other
operations should be performed by trained service personnel.
When working on ai>conditioning equipment, observe precautions in the literature, tags and labels attached to the unit, and
other safety precautions that may apply.
Follow all safety codes. Wear safety glasses and work
gloves. Use quenching cloth for unbrazing operations. Have
fire extinguishers available for all brazing operations.
Manufacturer
Ensum voltage listed on unit data plate agmes with electric_dsupply provided for the unit.
Disconnect gas piping fi_m unit when leak
testing at pressure greater than I/2 psig. Pmssums greater than ]12psig will cause gas valve
damage resulting in haz_u'dous condition. If
gas valve is subjected to pressure greater than
1/2 psig, it must be replaced before use. When
_ressure testing field-supplied gas piping at
?ressures of 1/2 psig or less, a unit connected to
;uch piping must be isolated by manu_dly closing the gas valve(s).
Before performing service or maintenance
operations on
unit, turn off main power switch to unit. Electrical shock
could cause personal injury.
INSTALLATION
Unit is shipped in the vertical configuration. To convert to
horizont_flapplication, remove side duct opening covers. Using
the same scmws, install coveLs on vertical duct openings with
the insulation-side down. Seals around duct openings must be
tight. See Fig. 1.
Step 1 -- Provide
ROOF CURB -- Assemble and install accesso U roof curb in
accor&mce with instructions shipped with curb. See Fig. 2.
Install insulation, cant strips, roofing felt, and counter flashing
as shown. Ductwork must be attached to curb. If electric or
control power is to be routed through the basepan, attach the
accessory thru-the-bottom
service connections to the basepan
in accordance with the accessory installation instructions. Connections must be installed befom unit is set on roof curb.

SLAB MOUNT (Horizontal
Units Only) -- Provide a level
concrete slab that extends a minimum of 6 in. beyond unit cabinet. Install a gravel apron in front of condenser coil air inlet to
plevent grass and foliage from obstructing airflow.
These units are designed for a minimum continuous returnair temperature in heating of 50 F (c_h_bulb), or an intermittent
operation down to 45 F (r_h_ bulb), such as when used with a
night set-back thermostat.
NOTE: Horizontal

To operate at lower return-air temperatures, a field-supplied
outdoor-air temperature control must be used to initiate both
stages of heat when the temperature is below 45 E Indoor comfort may be compromised
when these lower air temperatures
are used with insufficient heating temperature rise.
units may be installed
on a roof curb if
ALTERNATE UNIT SUPPORT -- When the curb or adapter
cannot be used, support unit with sleepers using unit curb or
adapter support alea. If sleepel_ cannot be used, support the
long sides of the unit with a minimum of 3 equally spaced
4-in. x 4-in. pads on each side.

The unit's 3/4-in. condensate &ain
connections are located on the bottom and end of the unit. Unit
discharge connections do not determine the use of c_h'ainconnections; either c_h'ainconnection can be used with vertical or
horizontal applications.
Ducts passing through an unconditioned

When using the standard end c_h'_dnconnection, make sure
the plug in the alternate bottom connection is tight before installing the unit.
To use the bottom drain connection for a roof curb installation, lelocate the factory-installed
plug from the bottom connection to the end connection. The center c_hainplug looks like
a star connection, however it can be removed with a l/2-in.
socket c_hive extension. See Fig. 4. The piping for the condensate c_h'ainand external trap can be completed after the unit is in
place.
Field Fabricate Ductwork -- On vertical
units, secure all ducts to roof curb and building structure. Do
not connect duct_'ork to unit. For horizont_fl applications, fieldsupplied flanges should be attached to horizontal discharge
openings and all ductwoN secured to the flanges. Insulate and
weatherproof all external ductwork, joints, and roof openings
with counter flashing and mastic in accordance with applicable
codes.

If a plenum return is used on a vertical unit, the return
should be ducted through the roof deck to comply with applicable fire codes.
A minimum clearance is not requiled around ductwork.
Cabinet return-air static pressure (a negative condition) shall
not exceed 0.35 in. wg with economizer or 0.45 in. wg without
economizel:
All units must have an extern_fl trap for condensate &'ainage. Inst_dl a trap at least 4 in. deep and protect against freezeup. See Fig. 5. If drain line is installed downsheam from the
extern_fl trap, pitch the line away from the unit at 1 in. per 10 ft
of run. Do not use a pipe size smaller than the unit connection.

Step 7 --
Make Electrical
Connections
On 3-phase units, voltages between phases must be balanced within 2% and the current within 10%. Use the fommla
shown in Note 3 under Tables 2A-2D to determine the percentage of voltage imbalance. Operation on improper line voltage
or excessive phase imbalance constitutes abuse and may cause
&image to electric_fl components. Such operation would inv_fli&tte any applicable Carrier warranty.
Unit cabinet must have an uninterrupted, unbroken electrical ground to minimize the possibility of personal inju U if
an electrical fault should occm: This ground may consist of
electrical wire connected to unit ground lug in control compartment, or conduit appl_)ved for electrical ground when
installed in accordance
with NEC (National Electrical
Code), ANSI/NFPA
(National File Protection Association), latest edition, and local electrical codes. Do not use
gas piping as an electrical ground. Failure to follow this
warning could result in the inst_dler being liable for persomd inju U of others.
NOTE: If thru-the-bottom
accesso U connections are used,
refer to the thin-the-bottom
accessol T installation instructions
for power wiring. Refer to Fig. 7 for location to &ill holes in
basepan.
FIELD CONTROL WIRING -- Install a Carrier-approved
accesso U thermostat assembly according to inst_dlation instructions included with the accesso U. Ix)cate thermostat
assembly on a solid wall in the conditioned space to sense
average temperature in accordance with thermostat installation
instructions.
FIELD POWER SUPPLY -- All units except
208/230-v
units are factory wired for the voltage shown on the nameplate.
If the 208/230-v unit is to be connected to a 208-v power
supply, the transformer must be rewired by moving the black
wire fiom the 230-v orange wile on the transformer
and
connecting it to the 200-v red wire fiom the transformer The
orange wire then must be insulated.
Route thermostat cable or equivalent single leads of colored
wire from thermostat subbase terminals to low-voltage connections on unit (shown in Fig. IIA and lIB) as described in
Steps 1-4 below.
1. ff unit is mounted on roof curb and accesso U thru-thebottom connections are used, route wire through connection plate.
Refer to unit label diagram for additional
infommtion.
Pigtails are provided for field service. Use factou-supplied
splices or UL (Undelwriters'
Laboratories) approved copper
connectoL
When installing
units, provide a disconnect
per NEC.
All field wiring must comply with NEC and local requirements. In Canada, electrical connections must be in accordance
with CSA (Canadian Standads
Associaion)
C22.1 Canadian
Electrical Code Part One.
2.
Pass control wires through the hole provided on unit (see
connection D, Connection Sizes table, Fig. 7).
3.
Feed wires through the raceway built into the corner post
to the 24-v barrier located on the left side of the control
box. See Fig. 12. The raceway provides the UL-required
clearance between high-voltage and low-voltage wiring.
Connect thermostat wires to screw terminals of lowvoltage connection boad (see Fig. 11A and 11B).
4.
Install conduit through side panel openings indicaed in
Fig. 7. Route power lines through connector to terminal connections as shown in Fig. 10.

Check MCA and MOCP when power exhaust is powered through the unit.

MCA New = MCA unit only + MCA of Power Exhaust
Example: Supply voltage is 460-3-60.

For example, using a 48HJD008 unit with MCA = 38.2 and MOCP = 45, with

power exhaust.
AB = 452 v
BC = 464 v
Average Voltage =
AC =455v
MCA New = 38.2 amps + 1.6 amps = 39.8 amps
If the new MCA does not exceed the published MOCE then MOCP would not
change. The M©CP in this example is 45 amps and the MCA New is below
45; therefore the MOCP is acceptable. If MCA New" is larger than the published M©CP, raise the MOCP to the next larger size. For separate power, the
MOCP for the power exhaust will be 15 amps per NEC.

Damper Movement -- Damper movement trom full open to
full closed (or vice versa) takes 2112minutes.
Thermostats -- The EconoMi$er IV control works with conventiomd thermostats that have a YI (cool stage 1), Y2 (cool
stage 2), Wl (heat stage 1), W2 (heat stage 2), and G (fan). The
EconoMi$er IV control does not support space temperature
sensors. Connections are made at the thermostat termimd connection board located in the main control box.
Exhaust Set Point Adjustment
-- The exhaust set point will
determine when the exhaust fan runs based on dmnper position
(if accessory power exhaust is installed). The set point is modified with the Exhaust Fan Set Point (EXH SET) potentiometer
See Fig. 38. The set point represents the damper position above
which the exhaust fans will be turned on. When there is a call
for exhaust, the EconoMiSer IV controller provides a 45 _+15
second delay before exhaust fan activation to allow the dampers to open. This delay _fllows file damper to reach the appropriate position to avoid unnecessary fan overload.
Occupancy Control -- The facto U default configuration for
the EconoMi$er IV control is occupied mode. Occupied status
is provided by the black jumper fiom terminal TR to terminal
N. When unoccupied mode is desired, inst_dl a field-supplied
timeclock function in place of the jumper between TR and N.
See Fig. 32. When the timeclock contacts are closed, the
EconoMi$er IV control will be in occupied mode. When the
timeclock contacts are open (removing the 24-v signal from
terminal N), the EconoMi$er IV will be in unoccupied mode.
Minimum Position Control -- There is a minimum damper
position potentiometer on the EconoMiSer [V controllel: See
Fig. 38. The minimum damper position maintains the minimum airflow into the building during the occupied period.
When using demand ventihttion, the minimum dmnper position represents the minimum ventilation position for VOC
(volatile organic compound)
ventilation requirements.
The
maximum demand ventilation position is used for fully occupied ventilation.

Demand Controlled Ventilation (DCV) -- When using the
EconoMi$er IV for demand controlled ventilation, them are
some equipment selection criteria which should be considered.
When selecting the heat capacity and cool capacity of the
equipment, the maximum ventilation rote must be evaluated for
design conditions. The maximum damper position must be calculated to provide the desired fresh air
Typically the maximum ventilation rate will be about 5 to
10% morn than the typical cfin required per person, using normid outside air design criteria.

Adjust the minimum position potentiometer
to allow the
minimum mnount of outdoor aik as required by local codes, to
enter the building. Make minimum position adjustments with
at least 10 F temperature difference between the outdoor and
return-air temperatures.
To determine the minimum
following procedure:

perform
1. Calculate the appropriate mixed air temperature
following formula:
OA
RA
(To x l-Tiff) + (TR x l-Tiff) = T M
A proportional anticipatory strategy should be taken with
the following conditions: a zone with a large area, varied occupancy, and equipment that cannot exceed the required ventilation rate at design conditions. Exceeding the required ventilation rate means the equipment can condition air at a maximum
ventilation rate that is greater than the required ventilation rate
for maximum occupancy. A proportional-anticipato U strategy
will cause the fresh air supplied to increase as the room CO2
level increases even though the CO2 set point has not been
reached. By the time the CO 2 level roaches the set point, the
damper will be at maximum ventilation and should maintain
the set point.
In order to have the CO 2 sensor control the economizer
damper in this manner, fil.'stdetermine the damper voltage output for minimum or base ventilation. Base ventilation is the
ventilation required to remove contmninants during unoccupied periods. The following equation may be used to determine
the percent of outside-air entering the building for a given
damper position. For best results there should be at least a
10 degree difference in outside and return-air temperatures.
the
using the

Carelhlly adjust the minimum position potentiometer

Once base ventilation has been determined, set the minimum damper position potentiometer to the correct position.
The same equation can be used to deterlnine the occupied or
maximum ventilation rate to the building. For example, an output of 3.6 volts to the actuator provides a base ventilation rate
of 5% and an output of 6.7 volts provides the maximum ventilation rate of 20% (or base plus 15 cfm per person). Use Fig. 43
to determine the maximum setting of the CO 2 sensol: For example, a 1100 ppm set point relates to a 15 cfm per person design. Use the 1100 ppm curve on Fig. 43 to find the point when
the CO2 sensor output will be 6.7 volts. Line up the point on the
graph with the left side of the chart to determine that the range
configuration for the CO 2 sensor should be 1800 ppm. The

Step 9 -- Adjust Evaporator-Fan
Speed -- Adjust evaporator-fan speed to meet jobsite conditions. Tables 7A
and 7B show fan rpm at motor pulley settings for standard and
_flternate motors. See Table 8 and Fig. 44 for accessory and option static pressure diops. See Tables 9A and 9B for evaporator
fan motor performance. Refer to Tables 10-23 to determine fan
speed settings. Fan motor pulleys are factory set for speed
shown in Table 1.
CO__, Sensor Configuration
-- The CO e sensor has preset
standard voltage settings that can be selected anytime after the
sensor is powered up. See Table 6.
NOTE: Befole adjusting fan speed, make sure the new fan
speed will provide an acceptable air temperature rise range on
heating as shown in Table 1.
To change fan speed:
1. Shut offunit power supply.
2. Ix_osen belt by loosening fan motor mounting nuts. See
Fig. 45 and 46.
3. Ix_osen movable pulley flange setscrew (see Fig. 47).
4. Screw movable flange toward fixed flange to increase fan
speed and away from fixed flange to decrease fan speed.
Increasing fan speed increases load on motol: Do not exceed maximum speed specified in Table 1.
5. Set movable flange at nearest keyway of pulley hub and
tighten setscrew. (See Table 1 for speed change for each
lull turn of pulley flange.)
To align fan and motor pulleys:
1. Ix_osen fan pulley setscrews.
2. Slide fan pulley along fan shaft.
3. Make anguhu" alignment by loosening motor from
mounting plate.
To adjust belt tension:
1. Ix_osen fan motor mounting nuts.
2. Si'..e 008 -- Slide motor mounting plate away from fan
scroll for proper belt tension (l/2-in. deflection with one
linger) and tighten mounting nuts (see Fig. 45).
Sizes 009-014 -- Slide motor mounting plate downward
to tighten belt tension. Secure motor mounting plate nuts.
See Fig. 46.
3. Adjust bolt and nut on mounting plate to secure motor in
fixed position.
Use setting 1 or 2 for Carrier equipment. See Table 6.

Dehumidification
of Fresh Air with DCV Control -- Information from ASHRAE indicates that the largest humidity load
on any zone is the fresh air introduced. For some applications,
a device such as a 62AQ energy recovery unit is added to reduce the moisture content of the fresh air being brought into the
building when the enthalpy is high. [n most cases, the norln_fl
heating and cooling processes are morn than adequate to remove the humidity loads for most commerci_fl applications.

To reset the control, bmak the 24 v power to WI.
If the limit switch trips at the stm-t of the heating cycle during the evaporator on delay, the time period of the on delay for
the next cycle will be 5 seconds less than the time at which the
switch tripped. (Example: If the limit switch trips at 30 seconds, the evaporato>fan on delay for the next cycle will occur

When free cooling is available the PremierLink control will
control the compressors and economizer to provide a supplyair temperature determined to meet the YI and Y2 calls from
the thermostat using the following three routines. The three
control routines are based on OAT.
COOLING. UNITS WITH ECONOMISER
IV -- When free
cooling is not available, the compressors will be controlled by
the zone thermostat.
When free cooling is available, the
outdoor-air &unper is modulated by tile EconoMiSer IV control to provide a 50 to 55 F supply-air temperature into the
zone. As the supply-air temperature fluctuates above 55 or below 50 L the dampers will be modulated (open or close) to
bring the supply-air temperature back within the set points.
The 3 routines me based on OAT where:
SASP = Supply Air Set Point
DXCTLO
= Direct Expansion
PID = Proportional
Integrated EconoMiSer IV operation on single-stage units
requires a 2-stage thermostat (YI and Y2).
For EconoMiSer IV operation, there must be a therlnostat
call for the fan (G). This will move the dmnper to its minimum
position during the occupied mode.
Routine
•
•
Above 50 F supply-air temperature, the &tmpers will modulate from 100% open to the minimum open position. From 50 F
to 45 F supply-air temperature, the &_mpers will maintain at
the minimum open position. Below 45 F the dampers will be
completely shut. As the supply-air temperature rises, the dampers will come back open to the minimum open position once
the supply-air temperature rises to 48 E
If optional power exhaust is installed, as the outdoor-air
damper opens and closes, the power exhaust fans will be energized and deenergized.
•
•
•
•
•
•
Damper movement from full closed to full open (or vice
versa) will take between 1I/2 and 21/2 minutes.
•
•
If free cooling can be used as determined from the appropriate changeover command (switch, @ bulb, enth_dpy curve,
differenti_d dry bulb, or differential enth_dpy), a call for cooling
(YI closes at the thermostat) will cause the control to modulate
the dampers open to maintain the supply air temperature set
point at 50 to 55 E

As the supply air temperature drops below the set point
range of 50 to 55 E the control will modulate the outdoor-tdr

The PremierLink controller will use the following information to determine if free cooling is available:
• Indoor fan has been on for at least 30 seconds.
• The SPT. SAT. and OAT inputs must have valid readings.
• OAT must be less than 75 F.
• OAT must be less than SPT.
• Enthalpy
must be LOW (may be jumpered
if and
enthalpy sensor is not available).
• Economizer
position is NOT forced.
When free cooling is available, the outdoor-air dmnper is
positioned through the use of a Proportional
Integral (PID)
control process to provide a calculated supply-air temperature
into the zone. The supply air will maintain the space temperature between the heating and cooling set points as indicated in
Fig. 49.
The PremierLink
control will integrate the compressors
stages with the economizer based on similar logic as the three
routines listed in the previous section. The SASP will float up
and down based on the error reduction calculations that compare space temperature and space set point.

SETPOINT
TIME
When outside-air temperature conditions require the economizer to close for a compressor stage-up sequence, the economizer control integrator is reset to zero aller the stage-up sequence is completed. This prevents the supply-air temperature
from dropping too quickly and creating a freeze condition that
would make the compressor turn off prematurely.
The high space set point is used for DX (direct expansion)
cooling control, while the economizer
space set point is a
calculated value between the heating and cooling set points.
The economizer set point will always be at least one degree
below the cooling set point, allowing for a smooth transition
from mechanical
cooling with economizer
assist, back to
economizer
cooling as the cooling set point is achieved.
The compressors
may be used for initial cooling then the
PremierLink controller will modulate the economizer using an
error reduction calculation to hold the space temperature
between the heating and cooling set points. See Fig. 49.
The controller uses the following conditions
economizer cooling:
• Enthalpy is Low
• SAT reading is available
• OAT reading is available
• SPT reading is available
• OAT < SPT
• Economizer Position is NOT forced

HEATING. UNIT WITH ECONOMISER2,
PREMIERLINK
CONTROL AND A ROOM SENSOR -- Every 40 seconds
the controller will calculate the required heat stages (maximum
of 3) to mtfintain Supply-Air Temperature (SAT) if the following qualifying conditions are met:
• Indoor fan has been on for at least 30 seconds.
• COOL mode is not active.
• OCCUPIED,
TEMR
COMPENSATED
START
or
HEAT mode is active.
• SAT reading is available.
• Fire shutdown mode is not active.
If all of the above conditions are met, the number of heat
stages is calculated; otherwise the required number of heat
stages will be set to 0.
If the PremierLink controller determines that heat stages are
required, the economizer damper will be moved to minimum
position if occupied and closed if unoccupied.
to determine
Staging should be as follows:
If Heating PIE) STAGES=2
• HEATSTAGES=I
(50% capacity) will energize HSI
• HEAT STAGES=2 (100% capacity) will energize HS2
If any of the above conditions are not met, the economizer
submaster reference (ECSR) is set to maximum limit and the
damper moves to minimum position. The operating sequence
is complete. The ECSR is rec;dculated every 30 seconds.
If an optional power exhaust is installed, as the outdoor-air
damper opens and closes, the power exhaust fans will be
energized and deenergized.
If field-installed
accessory CO 2 sensors are connected to
the PremierLink control, a PID-controlled
demand ventilation
strategy will begin to operate. As the CO 2 level in the zone
increases above the CO2 set point, the minimum position of the
damper will be increased proportionally.
As the CO 2 level
decreases because of the increase in flesh air. the outdoor-air
damper will be proportionally closed.

HEAT STAGES=2 (66% capacity) will energize HS2

In order to prevent short cycling, the unit is locked into the
Heating mode forat least 10 minutes when HSI is deenergized.
When HSI is energized the induced-draft motor is then
energized and the burner ignition sequence begins. On units
equipped for two stages of heat, when additiomfl heat is needed, HS2 is energized and the high-fire solenoid on the main gas
valve (MGV) is energized. When the space condition is satistied and HSI is deenergized the IFM stops after a 45-second

UNITS WITH THE HUMIDI-MIZER

ADAPTIVE
DEHUMIDIFICATION
outside air temperature switch will lock out this mode of
operation.
See Table 25 for file Humidi-MiZer a&tptive dehumidification system sequence of operation.
SYSTEM
Normal Design Cooling Operation -- When the rooftop operates under the normal sequence of operation, the compressol_
will cycle to maintain indoor conditions. See Fig. 50.
The Humidi-MiZer
adaptive dehumidification
system includes a factory installed Motormastel®
low ambient control
to keep the head and suction pressure high, tallowing normal
design cooling mode operation down to 0 ° IF.
Subcooling Mode -- When subcooling mode is initiated, this
will energize (close) the liquid line solenoid valve (LLSV)
forcing the hot liquid refrigerant to enter the subcooling coil
(see Fig. 51 ).
As the hot liquid refrigerant passes through the subcoolinJ
reheat dehumidification
coil, it is exposed to the cold supply
airflow coming fllrough the evaporator coil. The liquid is further subcooled to a temperature approaching the evaporator
leaving-air temperature. The liquid then entel_ a thermostatic
expansion valve (TXV) where the liquid drops to a lower pressure. The TXV does not have a pressure drop great enough to
change the liquid to a 2-phase fluid, so the liquid then enters
the Acutrol TM device tit the evaporator coil.
Fig. 50 -- Humidi-MiZer Normal Design
Cooling Mode Operation
The liquid enters the evaporator coil tit a temperature lower
than in standard cooling operation. This lower temperature
increases the latent capacity of the rooftop unit. The refrigerant
passes through the evaporator and is turned into a vapor. The
air passing over the evaporator coil will become colder than
during normal operation. Howevel: as this same air passes over
the subcooling coil, it will be slightly warmed, pmtially reheating the ail:
Subcooling mode operates only when the outside-air temperature is wmmer than 40 E A factory-installed
temperature
switch located in the condenser section will lock out subcooling mode when the outside temperature is cooler than 40 E
The scroll compressors are equipped with crankcase heaters
to provide protection for the compressors due to the additiomd
refrigerant charge required by the subcoolinJleheat
coil.
When in subcooling mode, there is a slight decrease in
system total gross capacity (5% less), a lower gross sensible
capacity (20% less), and a greatly increased latent capacity (up
to 40% more).
VALVE
Fig. 51 -- Humidi-MiZer
Subcooling
Operation
Hot Gas Reheat Mode -- When the humidity levels in the
space require humidity control, a hot gas solenoid valve (specific to hot gas leheat mode only) will open to bypass a portion
of hot gas refrigerant around the condenser coil (see Fig. 52).
This hot gas will mix wifll liquid refrigerant leaving the condenser coil and flow to the subcooling/reheat
dehumidification
coil. Now the conditioned air coming off the evaporator will be
cooled and dehumidified, but will be wmmed to neutral conditions (72 F to 75 F) by the subcooling/reheat
dehumidification
coil.
NOTE: The 48HJ008-014 rooftop units can operate one circuit
in subcooling mode and one circuit in hot gas reheat mode or
both circuits in hot gas reheat mode, or both in normal design
cooling mode.
The net effect of the rooftop when in hot gas reheat mode is
to provide nearly tdl latent capacity removal from the space
when sensible loads diminish (when outdoor temperature conditions are moderate). When in hot gas reheat mode, the unit
will operate to provide mostly latent capacity and extremely
low sensible heat ratio capability.
Similar to the subcooling mode of operation, hot gas reheat
mode operates only when the outside-air temperature
is
warmer than 40 E Below this temperature, a factory-installed
