10-6. Checking Component Parts' Function
Part Name Checkpoints
Notes:
1. If the water ow rate is less than the minimum ow rate setting
of the ow sensor (default 5.0 L/min), the ow rate error will be
activated.
2. If the water ow rate exceeds 36.9 L/min, the ow speed will be
greater than 2.0 m/s, which could erode the pipes.
*1 Flow rate recommended for installation
*2 With bu󰀨er tank
*3 If you want to secure the maximum ow rate, please install an
additional pump.

Note: For installation of E*PX series, set its pump speed with a pressure drop between
the hydrobox and the outdoor unit factored into the external static pressure.
