NOTE: For installations not indicated above the following
formula is to be used:
TR = (kW x 3412) x (Voltage Correction) x 1.08 / CFM
Where: TR
kW = Heater Kit Actual kW
3412 = Btu per kW
Voltage Correction
1.08 = Constant
CFM = Measured Airflow
NOTE: The Temperature Rise Tables can also be used to
determine the air handler airflow delivery. When using these
tables for this purpose set the room thermostat to maximum
heat and allow the system to reach steady state conditions.
Insert two thermometers, one in the return air and one in the
supply air. The temperature rise is the supply air temperature
minus the room air temperature.
Use HKR specification sheets to determine the HKR avail-
able for a given air handler.

HKR Installation

Follow instructions listed in Installation and Operating Instruc-
tions shipped with the heat kit.

Electrical Supply Wire and MOP

FIRE HAZARD!
To avoid the risk of property damage, personal injury
or fire, use only copper conductors.
HIGH VOLTAGE!
Disconnect ALL power before servicing.
Multiple power sources may be present.
Failure to do so may cause property damage,
personal injury or death.

To avoid property damage, personal injury or death
due to electrical shock, this unit MUST have an
uninterrupted, unbroken

appropriately sized electrical wire connecting the
ground lug in the unit control box to the building

Other methods of grounding are permitted if performed
34
in accordance with the National Electric Code
(NEC)/American National Standards Institute
(ANSI)/National Fire Protection Association (NFPA) 70
and local/state codes. In Canada, electrical grounding
is to be in accordance with the Canadian Electric Code
(CSA) C22.1.

Building Electrical Service Inspection

This unit is designed for single-phase electrical supply. DO
NOT OPERATE ON A THREE-PHASE POWER SUPPLY.
Measure the power supply to the unit. The supply voltage
must be in agreement with the unit nameplate power require-
ments and within the range shown in Table 5.
Nominal Input
208/240

Wire Sizing

Wire size is important to the operation of your equipment.
Use the following check list when selecting the appropriate
wire size for your unit.
• Wire size must carry the Minimum Circuit Ampac-
ity (MCA).
• Refer to the NEC (USA) or CSA (Canada) for wire siz-
ing. The unit MCA for the air handler and the optional
electric heat kit can be found on the unit Series and
Rating Plate.
• Wire size allows for no more than a 2% voltage drop
from the building breaker/fuse panel to the unit.
Refer to the latest edition of the National Electric Code
or in Canada the Canadian Electric Code when deter-
mining the correct wire size. The following table shows
the current carrying capabilities for copper conductors

tors.
