Valve Installation
Note: Pipe dope and Teflon tape are not required for any of the valve threads.
The valve is normally installed at the faucet that is furthest away from the hot water heater. If there are separate hot water branches in the residence,
additional valves may be required.
1)
Close both the hot and cold angle stop valves under the sink.

2)
Open both the hot and cold water faucets to relieve the water pressure.
3)
Disconnect the riser pipes or hoses from the angle stop valves. Place a pan or rag below the connections to catch any water that may leak
from the risers.

Setting Instructions
1)
To set the current time, rotate the outer ring until the arrow head lines up with the correct time.
This is a 24-hour clock so 1 to 12 on the clock indicates 1am to noon and 13 to 24 on the clock indicates 1pm to midnight.
2)
To set the time that the pump will operate, move all tabs outward during the time period. Example: To set on at 7:00am and OFF at 10:00am,
move all of the tabs between 7 and 10 to outward position.
3)
By following the instructions in step 2 multiple on-off cycles can be set.
4)
The override switch has 3 positions The “I” indicates the pump will run continuously (24 hours a day). The position next to the clock symbol
indicates the pump will follow the settings of the tabs. The “O” indicates the pump is off (not running).
For Digital Timer models refer to the attached Grasslin Model FM1D14 Instructions.
