Notes:
1) Before installation and debugging, please read these prompts carefully!
2) This hot water generator is only used for closed type water system, open type system
such as no-coil water tank should not use this hot water generator; it should be
installed indoors with ambient temperature of 4℃～35℃. It is not allowed to install
outdoors, otherwise it may cause malfunction.
3) If the unit will not be operated for long or the unit is de-energized, please drain the
pipelines of generator, water tank and floor heating, otherwise the equipment will be
frozen; during installation, please add draw off valve in water inlet and outlet of hot
water generation to avoid inadequate drainage and freezing of system.
4) Before energizing the unit, please check if ―S2‖ dial code in mainboard is consistent
with actual situation of connecting equipment, otherwise it may impact reliability of unit
and will give out temperature sensor malfunction.
5) If water pressure for water replenshing is larger than 3bar, please install reducing
valve in water replenishing inlet of equipment to ensure water pressure of system
is≤3bar, otherwise atmospheric valve and other valves will open and lead to water
leakage;
6) Connect to floor heating equipment, if crushing of water system other than hot water
generator is larger than 6m, please install engineering water pump.
7) Wired controller of air conditioner can control floor heating, for specific setting and
operation please carefully read the instruction manual of hot water generator and
