When the air accumulates in the pipe, the resistance of the water circuit will increase and the flow rate will extremely decrease. Because of this, an installation of automatic air venting valves is required when there is a pipe that slopes down in the outlet hot water pipe. Install the pipe with an upward gradient of 1/200 or more toward the air vent to prevent air accumulation in the pipe. Also, install air venting valves to the places where air can accumulate. The installation example is shown below. Note: • If the crosscut pipe is located lower than the hot water outlet of the heat pump unit, raise the pipe near the unit and install an automatic air venting valve. [5] Outlet check valve (When installing multiple units) When connecting multiple units with pipes in parallel, install a check valve at the outlet pipe of each unit. If a check valve is not installed, a circuit in which warm water flows back will be created in some units during the defrost cycle or abnormal stop, and other units will come to an abnormal stop due to sudden change of the inlet water temperature.
