Setting the Circulator Timer:
1. Set timer to exact time of day by turning the clock face
clockwise. Be sure to align the time arrow with the cor-
rect AM/PM settings in outer ring.
2. Plug power cord into nearest 115V power outlet. Set
timer manual switch to ON to test for pump operation.
Run pump in manual mode for 5 minutes to purge air
from pump. See clock face diagram.
3. To set the desired ON/OFF operation times, push the
trippers away from the clock face at the corresponding
hour/minute for ON times. Push trippers toward clock
face for OFF times. Each tripper represents 15 minutes.
4. After all ON/OFF times are set, move timer manual
switch to middle AUTO position for automatic operation.
Installing the Hot-Link Valve:
1. Select the hot water faucet furthest from the water
heater. If your plumbing system branches in two differ-
ent directions, another
Hot-Link Valve
may need to be
installed at the end of each run.
2. Shut off the hot and cold angle stop valves below the
sink.
3. Open the hot and cold faucets to purge water from the
lines.
4. Disconnect the hot and cold flex hoses from the

them to the respective hot and cold inlet ports on the
Hot-Link Valve
. Locate the flow arrows on the side of
the valve to verify flow direction.

water connection on the faucet (right side).
6. When all connections are made, open angle stop
valves and check for leaks.

to the wall using anchor
screws provided.
