;The 1 gallon (3.8 liter) reservoir is not designed to withstand water pressure above 5 psi (34 kPa).

;The fill opening and vent line must be vented to the atmosphere for proper operation.

Properly Venting and Filling the Reservoir Tank

To properly vent and fill the tank:

Remove the side panel, then remove the bushing installed on the top of the tank.

Install a pipe nipple and tee to the ¾” coupling on top of the tank.

Use one side of the tee for the vent line and the other side for the fill line.

Fill the tank.

Remove the fittings and re-install the bushing

Extend the vent line from the tank to a proper drain.

Re-install the side panel.
