FLA — Full Load Amps
HACR — Heating, Air Conditioning and Refrigeration
IFM — Indoor (Evaporator) Fan Motor
LRA — Locked Rotor Amps
MCA — Minimum Circuit Amps
MOCP— Maximum Overcurrent Protection
NEC — National Electrical Code
OFM — Outdoor (Condenser) Fan Motor
RLA — Rated Load Amps
*Heater capacity (kW) is based on heater voltage of 208 v, 240 v,
480 v, and 600 v. Heaters are rated at 240 v, 480 v, or 600 v. If power distribution voltage to unit varies from rated heater voltage, heater kW will vary accordingly. To determine heater capacity at actual unit voltage, multiply 240 v, 480 v, or 600 v capacity by multipliers found in table on page 51.
†Used to determine minimum disconnect size per NEC.
**Heaters are field installed only.
†† Fuse or HACR circuit breaker.
||Fusing in single point box provides the required branch circuit protection.
NOTES:
1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. The
Canadian units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage is
greater than 2%. Use the following formula to determine the percent of voltage imbalance.
% Voltage Imbalance
= 100 x max voltage deviation from average voltage average voltage
Example: Supply voltage is 460-3-60.
AB = 452 v
BC = 464 v
AC = 455 v
Average Voltage =
452 + 464 + 455
3
=
1371
3
= 457
Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
7
% Voltage Imbalance = 100 x
457
= 1.53%
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.

2. Maximum usable watts input is 2120 and maximum continuous bhp is 2.
90. Extensive motor and electrical testing on these units ensures that the full range of the motor can be utilized with confidence. Using your fan motors up to the wattage ratings shown will not result in nuisance tripping or premature motor failure. Unit warranty will not be affected.
3. Values include losses for filters, unit casing, and wet coils.
4. Use of a field-supplied motor may affect wire sizing. Contact your
Carrier representative for details.
5. Interpolation is permissible. Do not extrapolate.
6. Motor Efficiency: 85%.

PROBLEM
Damper does not open.
EconoMi$er operation limited to minimum position.
Damper position less than minimum position set point.
Damper does not return to minimum position.
Damper does not close on power loss.
CAUSE
Indoor (evaporator) fan is off.
No power to
G terminal.
Controller fault.
Thermostat fault.
Actuator fault.
Supply air low limit strategy controlling.
Table 13 — EconoMi$er Service Analysis
No power to EconoMi$er controller.
Minimum position set incorrectly.
EconoMi$er changeover set point set too high or too low.
Supply air temperature sensor faulty.
OAT sensor faulty.
REMEDY
Check to ensure that 24 vac is present at Terminal C1 (common power) on the IFC
(indoor [evaporator] fan contactor) or that 24 vac is present at the IFO (indoor [evaporator] fan on) terminal. Check whether 24 vac is present at PL (plug) 6-1 (red wire) and/or
PL6-3 (black wire). If 24 vac is not present, check wiring (see unit label diagram).
Check proper thermostat connection to G on the connection board.
Check to ensure that 24 vac is present across terminals 24 VAC and 24 v COM on the
EconoMi$er control. If 24 vac is not present, check wiring (see unit label diagram).
If 24 vac is present, status light should be on constantly.
If IFM is on, check to ensure 24 vac is present on G terminal of the EconoMi$er controller. If 24 vac is not present, check wiring (see unit label diagram).
If STATUS light is flashing one flash, the EconoMi$er controller is experiencing a fault condition. Cycle power to the controller. If condition continues, replace the EconoMi$er controller.
If STATUS light is flashing two flashes, the EconoMi$er controller believes the thermostat is wired incorrectly. Check wiring between the thermostat and the connection board in the electrical panel. The fault condition is caused by Y2 being energized before Y1.
Check the wiring between the EconoMi$er controller and the actuator. Hold CONFIG button between three and ten seconds to verify the actuator’s operation. (This process takes three minutes to complete.)
Verify that the MIN POS (%) is set greater than zero. Adjust MIN POS (%) to 100% to verify operation, and then set to correct setting.
Set at correct value. See Table 2.
If STATUS light is flashing four flashes, the supply air temperature sensor is faulty.
Check wiring or replace sensor.
If STATUS light is flashing five flashes, the OAT (outdoor-air temperature) sensor is faulty.
Check wiring or replace sensor.
The supply air temperature is less than 45 F, causing the minimum position to decrease.
Refer to the Start-Up instructions. Verify correct setting of MIN POS (%). If correct,
EconoMi$er is operating correctly.
CO

ventilation strategy controlling.
Damper travel is restricted.
If a CO
2
sensor is being used, and the damper position is greater than minimum position, the ventilation control strategy is controlling. Refer to
the Start-Up instructions. EconoMi$er is operating correctly.
Check to ensure the damper is not blocked.

Frequently asked questions
This document provides instructions on how to install, start-up and service single-package rooftop units.
Installation and servicing air-conditioning equipment can be hazardous. Only trained and qualified service personnel should install, repair, or service air-conditioning equipment.
The evaporator-fan speed can be adjusted using the belt-drive motor mounting.
The condenser coil can be cleaned by separating the coil sections and using a brush or vacuum cleaner.
The condenser fan can be adjusted by changing the fan height.
