Return to service after shutdown of two weeks or more
You may choose to turn the system off (slide the pump timer switch to the “OFF” position)
as there is no need to maintain hot water in the supply line when no one is home. Before
turning the system back on, follow these instructions:
1. Open the faucets/taps at the sink where the system is installed. Keep them open until
all air is purged and the water flows smoothly.
2. Slide the pump switch back to either the "ON" position or the clock position for Timer
Operation.
