208/1/60 Supply Voltage - Temperature Rise Table °F

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		= Temperature Rise
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.

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.

HIGH VOLTAGE!

To avoid property damage, personal injury or death due to electrical shock, this unit MUST have an uninterrupted, unbroken electrical ground. The electrical ground circuit may consist of an appropriately sized electrical wire connecting the ground lug in the unit control box to the building electrical service panel.

Other methods of grounding are permitted if performed 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	Minimum Voltage	Maximum Voltage

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 rated at 75oC with a 2% voltage drop. Use Table 6 to determine the voltage drop per foot of various conduc- tors.
