
Slide a measured length of Armaflex onto each of the PEX lines.

Now repeat the process of connecting, and securing the PEX to the (2) ¾” PEX barb
fittings on the water inlet and outlet of the Geyser-R.

CONNECT AS FOLLOWS:
o
The PEX line that starts closest to the tank connects to the BOTTOM RIGHT
connection on the Geyser (water into Geyser)
o
The PEX line that starts further from the tank connects to the TOP LEFT
connection on the Geyser (water out of Geyser)

Make sure Armaflex covers the hose and fittings to minimize heat loss.

Once you have the PEX tubing connected to both the unit and the water tank, you may
now open the cold water valve on the top of the tank to begin filling the tank (this will
also allow you to check the connections for leaks!).

Leave one faucet open in the house while filling to allow air in the tank and lines to
escape.

Once the water begins running through the faucet the system is full of water and you
can close the faucet.
