Start-Up Process
1) System Leak Check
After all indoor and outdoor refrigerant bearing components of the system have been installed and
joints have been nitrogen brazed, pressurize the system prior to evacuation to leak test the system.
Do not exceed 150 psig when pressure testing the compressor unit and indoor system components.
Test for leaks with a sensitive electronic leak detector and bubble solution.
Repair leaks as appropriate prior to evacuation.
Evacuation and charging of the system is done through the compressor unit. All of the refrigerant
containing components in the compressor unit are illustrated in Figures 23 and 24.
The Start-up Process is illustrated in Figure 31.
CAUTION!
During the Evacuation and Initial Charging processes, be sure that ALL
power to the EarthLinked
®
System is OFF. This includes the
compressor unit, air handler and all other electrically powered system
components. Failure to do so will cause lockout on start-up.
