TRW ST Series Crossover Return Conversion Instructions
To use a crossover valve for recirculation, the PVA and check valve must be removed from the RUR98 unit and
replaced with a cold water flex line. A PVA must be added to the RUC98 units. For a TRW02ST, the cold line flex for
the RUR98 can be removed from the RUC unit. You will then remove the check valve from the flex line assembly from
the RUR98 and add it to the RUC unit. For applications with a TRW03ST, Kit 104000278 must be purchased to
add a PVA valve and threaded nipple to the second RUC unit.
For conversion to crossover recirculation, follow the steps below.
1. Remove the cold flex assembly from the RUR98 unit.
