ELECTRICAL ADJUSTMENTS
This series of electric cooling and heat pump package equipment
is designed to accept a field-installed electric heat kit. The unit is
equipped to easily install the HKR Series Electric Heat Kit. Full
installation instructions are included in this kit. Please use this
document for guidance in field equipping the package unit with
electric heat.
Choose the heat kit that fits the application for the specific
installation. Permanently mark the unit’s nameplate with the
model being installed. High and low voltage connections are
detailed in the heat kit instructions.
Indoor blower motor speed tap selection may need to be
modified to accommodate normal continuous operation to
prevent a nuisance trip. See the following charts.
