Goodman LAKT01 Low Ambient Kit

The LAKT01 and LAKT03 low ambient kits (for Light Commercial Models and Residential Splits) are temperature sensitive fan motor speed controls designed to regulate the outdoor section head pressure by varying the air volume through the outdoor coil and are required when operating below 55°F outdoor temperature. This is achieved by sensing the liquid temperature at the coil by means of a thermistor probe. The probe provides an input signal to the control to increase the fan motor speed in relation to changes in the liquid temperature. Ensure all parts are included before beginning.

NOTE: These kits are not approved for any 16 and 18 SEER outdoor units that utilize an ECM condenser fan motor.

The following accessories must be installed on all condensers and remote heat pumps when equipped with low ambient kits.

1. Crankcase heater must be installed if not factory installed.

2. Hard start kit for single phase units. (See Spec Sheet for Accessories)

3. TXV kit installed on indoor evaporator coil, if not factory installed.

4. FSK01A - Freeze protection kit must be installed on indoor coil.

5. Wind buffer must be installed for temperatures below 0oF or areas with high prevailing winds. Wind buffer can be a wall fabricated from wood or masonry material that will prevent the prevailing wind from causing the outdoor fan to rotate. NOTE: When wind buffer is installed, it is necessary to use minimum 4" risers to elevate the unit off of the pad to provide better airflow for moderate and high ambient temperatures.
