Remark:
1. For the first time use, ensure the water tank have been filled with water before power on to prevent
burn out. Meanwhile, the circulation water pipe should be filled with water, no air left inside. Checking
the pipe to ensure the water circulates successfully.
2. Follow with the water heater unit, there are some installation parts (see the annex detail list of parts).
As for other water system components, the user or installation company should provide by themselves.
3. Before installation, it’s better to reserve a water supply pipe interface, hot water outlet pipe interface
and drainage pipe interface. Among them, the water supply pipe and hot water outlet pipe should be
used in line with standards for drinking water pipes. (E.g. PPR pipe or stainless steel pipe, etc.), can
not use iron pipe or the rubber hose with odor for installation.
4. If the using place below 0 ,℃ please adopt the second circulation system (connect solar coil in the
water tank), the heat-conducting medium should be anti-freezing liquid (propanediol suggested).
Make sure to insulate the water pipes to prevent frozen.
5. Air inlet /outlet can connect Φ153mm vent tube, but pipe should not be too long and less crankle.
