SERIES-CONNECTED SOLAR ENERGY
The ES20CF-2-NG and ES26CF-2-NG models can be connected with solar energy in series.
• The wire controller should not be installed when solar energy is connected in series.
• In the Australian market, the gas water heater (GWH) is connected in series with the solar energy system. GW is only an accessory of
solar energy, named “gas booster,” and its main system is solar energy. The preset temperature of the water outlet of the gas water
heater is 70℃.
• The gas water heater will not ignite when the water inlet pipe of the gas water heater is connected with the water outlet pipe of solar
energy, and the water inlet temperature of the gas water heater is higher than or equal to 58℃; start burning when the temperature of
the inlet water is lower than 58℃; stop burning for 10 seconds continuously when the temperature of the inlet water is higher than or
equal to 60℃;
• Special requirements for connecting solar energy in series:
1. The gas water heater is used as a supplementary device for heat sources, and the burning stops after burning for 1 hour, and the
burning can be started by switching on and off the water again;
2. In the case of minimum load burning, stop the burning when the temperature of the outlet water is ≥ the set temperature +3℃ for
20s or the temperature of the outlet water is ≥78.5℃; burning can be started by switching on and off the water and the device
again;
3. To prevent scalding by hot water, the actual temperature of the outlet water is associated with the water ow and temperature of
the inlet water. Please conrm the temperature of hot water by hand before using it;
4. The ex-factory temperature is 50℃, and the highest temperature is 75℃. The temperature of 70℃ can be adjusted by a qualied
installer to connect solar energy in series (bacteria legion killing), and the wire controller cannot be used when connecting
solar energy in series. Furthermore, the temperature of the surface cover can be lowered by a qualied installer, and the set
temperatures are 75, 70, 65, 60, 55, 50, 48, 45, 43, 42, 40, and 38.
5. When connecting solar energy in series, E4 fault will be reported in case the temperature of the inlet water or the temperature of
the outlet water is beyond 90 degrees.
6. When connecting solar energy in series, the mode of connecting solar energy in series will be started by default when the set
temperature is greater than 70 degrees.
Freeze prevention
WARNING
If freezing conditions are expected, turn off water / gas supply and drain the water from the appliance.
• Turn off the water supply valve;
• Turn off the gas supply valve;
• Turn off the power supply switch;
• Drain the water from the water heater (refer to p.19).
If power supply is on, and the automatic anti-freezing protection system will be running and the freezing will be prevented. Only the pipes and heat
exchanger inside the water heater will be protected. Any hot or cold water pipes located outside of the unit will not be protected. Proper protection
and insulation of these pipes will be required to ensure these are protected from freezing.

THE FOLLOWING CONDITIONS ARE NOT A FAULT
Fault Description Handling Method
White exhaust smoke.
Outdoor temperature is too low, the exhausted ue gas
condenses into white mist when it meets cold air.
Burner will not ignite at low water ow rate.
Water ow rate is too low to ignite the burner. Increase water ow rate
to initiate proper operation.
Can’t supply high temperature hot water in winter.
The supply cold water temperature is very low and the water
adjustment knob is already has been turned to the maximum; the set
temperature may exceed the heating capacity, and then please turn
down the water ow.
Failure to provide low temperature hot water in summer.
The temperature of supplied cold water is too high and the set
temperature of hot water is too low. If the inlet water ow is less
than 3L/min in this case, it may cause the hot water temperature
to be higher than expected. Please adjust the water ow rate more
appropriately.
After 12 hours of use, the water heater suddenly ameouts.
To prevent oxygen deciency, the water heater has a 12-hour timer
protection function, which automatically shuts off when it runs
continuously for 12 hours. Please close the hot water tap for a period
of time and then restart it.
Close the hot tap, but the blower did not stop immediately.
To completely purge the ue gases, the water heater has a shut-off
delay function to ensure the safety of the user. This is why the blower
will run for about 25-60 seconds even after the hot tap is turned off.
Open the hot water tap, but can’t provide hot water in time.
There is a distance from the water heater to the hot water tap because
there is some cold water in the pipes that takes some time to ow out
before the hot water arrives. The farther the distance, the longer you
need to wait.
There is always some water coming out of the drain valve.
This is because the inlet water pressure is over 1.0MPa, drain valve
which is located on the water outlet will work to release the high
pressure (refer p.19). Install a pressure limiting valve on the cold
water supply chain.
