Second thought. When using fresh water tank ( pump on ), it can take along time to fill the hot water tank with water, and while doing so, you won't get any water out of the cold side- just lots of sputtering air as the water enters the hot water tank and pushes all the air out of the lines. The pump will run the whole time until the tank fills.
Also, outside in the maintenance door for the hot water tank: 1) make sure the drain plug is in and closed., usually white plastic plug at bottom 2) with the pump on, pull up on the pressure release valve and bleed the air from the hot water tank, usually at the top of the tank with a small brass lever.
