Important Warning: Risk of Incorrect Installation - E1 error high pressure failure 

If the Dominator Series 2 unit is installed in reverse without following this procedure, there will be no airflow through the heat exchanger, causing the unit to fail on high pressure (E1 error).
The YouTube Video guide describes the process of reversing the coil to ensures correct airflow direction and system performance.

Overview

The Dominator Series 2 comes standard with Left-hand Return and Right-hand Supply (when facing the wall). This guide explains how to reverse the unit to Right-hand Return and Left-hand Supply.

STANDARD CONFIGURATION - LEFT-HAND RETURN AND RIGHT-HAND SUPPLY (when facing the wall) - Airflow through the heat exchanger



REVERSE CONFIGURATION - RIGHT-HAND RETURN AND LEFT-HAND SUPPLY (when facing the wall) - Airflow through the heat exchanger


Intended Audience

Installers and technical personnel responsible for configuring and installing Dominator Series 2 units.
