INSTRUCTIONS for AMH3K-7(N) (see Fig. 1)
1.
Locate the hot and cold shut off valves (angle stops)
typically located near the faucet(s) under the counter.
2.
Close both shut off valves and disconnect the flexible
hoses attached to each valve by turning the nut at the end
of the hoses counter-clockwise.
3.
Install one Tee at each valve. Connect the female port of
the Tee to the port on the valves from which you have just
disconnected the hoses.
4.
Connect the hoses which you had disconnected from the
valves to the top port of the Tee.
MAKE SURE YOU
CONNECT THE HOSES TO THE SAME VALVE TO
WHICH THEY HAD ORIGINALLY BEEN CONNECTED.
5.
Attach the unions (gaskets, nuts and tail pieces) to the
pump casing. The gaskets must be located between pump
casing and tail piece
.
MAKE SURE THE TAIL PIECE
MARKED RED IS MATCHED UP WITH THE RED
MARKING ON THE INLET SIDE (THAT IS OPPOSITE
DIRECTION OF ARROW) OF THE PUMP.
You will need
two pipe wrenches that
open to at least 1 1/2” inches.
Firmly tighten the two union nuts to avoid leaks. Do not
install the pump upside down.
6.
Place the pump into its intended location with the bracket
on the floor and fasten with screws if necessary. It is also
possible to install the pump horizontally but make sure that
the wall to which it is fastened is sturdy enough to support
the pump
NOTE: Be sure the arrows on the pump
point to the cold water side.
7.
Install the flex hoses by attaching one end to the remaining
port of the Tee and the other end to the pump.
MAKE
SURE THE HOSE ATTACHED TO THE HOT
VALVE IS
CONNECTED TO THE INLET SIDE (THAT IS THE
OPPOSITE DIRECTION OF THE ARROW) OF THE
PUMP. MAKE SURE THE HOSE ATTACHED TO THE
COLD VALVE IS CONNECTED TO THE DISCHARGE
SIDE (THAT IS THE SIDE THE ARROW IS POINTING
TO) OF THE PUMP.
8.
Open the valves. Check for leaks.
9.
Plug in the cord to any convenient grounded, 115 volt
outlet. Your kit contains a circulator with a built-in timer.
Follow the step by step directions on the timer instruction
sheet to program the timer to meet your hot water needs.
10.
The system will settle in 2 to 3 hours. Opening faucets will
help release any trapped air.
