Pre-Installation

This EarthLinked® Hybrid Cooling Module (HCM) is for use with EarthLinked®

space heating and cooling systems that provide cooling. The HCM is a required

component of the EarthLinked® systems where indicated in the EarthLinked®

Performance Tables for R-410A systems.

This Hybrid Cooling Module (HCM) is pre-programed using A-419 temperature controllers. A

sensor connector is pre-installed in the HCM cabinet and the sensor is to be placed on the liquid

line. This allows for temperature-based fan control: the HCM cycles on when the liquid line

temperature reaches 110⁰F and cycle off once when the liquid line temperature drops to 105⁰F.

This temperature range is high enough to keep the Cooling Assist Valve closed and low enough

to keep the head pressure down when needed.

If the HCM is installed as a retrofit, the refrigerant charge in the existing system must be

recovered before HCM installation. Use new refrigerant to recharge the system.

Application of the Hybrid Cooling Module (HCM) to EarthLinked

use of two (2) field supplied Type ACR copper couplings to match the HCM with the line

set vapor tube size. See the table below to determine the required coupling sizes.
