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-
r
ect AM/PM settings in outer ring.
2. Plug power cord into nearest 115V power outlet. Set

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

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
1
⁄2"
faucet connections beneath the sink and reconnect
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.
5. Install the
1
⁄2" x
1
⁄2" flex hoses provided. Connect one
hose to the hot outlet of the valve and the hot water
connection on the faucet (left side). Connect the sec-
ond flex hose to the cold outlet of the valve and the
cold water connection on the faucet (right side).
6. When all connections are made, open angle stop
valves and check for leaks.
7. Attach the Hot-Link Valve to the wall using anchor
screws provided.
Note: The Hot-Link Valve can be disassembled for service
and cleaning. Repeat steps number 2 and 3. Unthread the
valve stem from the body and clean internal screen of
