INSTALLING THE REFRIGERANT PIPING

Heat Recovery Unit Refrigerant

Piping Connections

• The 96k Hydro Kit requires the use of two ports twinned together

when connected to a Heat Recovery Unit. Use LG Y-Branch Kit
ARBLN03321 for this application.

• If the capacity of the Hydro Kit and other indoor units connected to

the Heat Recovery Unit are similar, install the Hydro Kit on Ports 1
and 2.

• Ports are numbered right-to-left on the new PRHR*3A heat recov-

ery units.

• Refer to the specific Air-Source / Water-Source Installation Manual

for detailed information about Heat Recovery Unit installation.

Figure 10: Y-Branch Kit for Twinning Heat Recovery Ports.

When Pre-Commissioning / Addressing Systems with Hydro Kits

• The pipe numbers of the connected vapor and liquid pipes must be the same.
• Ensure that there is flow of water during the auto addressing / valve port detection procedure.
• Each indoor unit (including Hydro Kits) is assigned a unique address and is detected by the outdoor unit while performing the auto address-

ing / valve port detection process.

Auto Addressing / Valve Port Detection with Hydro Kits
1. Choose the "Mode" according to the water temperature.
• Use "Mode 1" if the water temperature is higher than 86°F (30°C).
• Use "Mode 2" if the water temperature is lower than 86°F (30°C).

2. Ensure that there is flow of water (the water pump is operating) during the auto addressing / valve port detection process.
• If water circulation is not detected by water flow switch, a "CH14" error will occur.

• An auto addressing / valve port detection process error will occur if the Hydro Kit piping temperature does not increase.
• For detailed information on Pre-Commissioning, Addressing, Valve Port Detection procedures, review the installation manual for the specific

outdoor unit / water-source unit.
