Water heaters must be protected before travelling to a possible freezing environment.
Freezing damage is not covered by the warranty. The anti-freezing function operation
method is:
When the water temperature in the water heater is lower than 6±1° C (43° F±2° F), the
wire controller displays "
Fd ", the machine starts the ignition and runs with a certain
load. After the whole machine runs for 5 seconds, the water heater will automatically
shut off or when the temperature of the water pipe reaches 32±1° C (90° F±2° F) in 2
seconds, it will shut down automatically. Heater will run the test again after shut down
for 3 minutes.
In the process of starting the antifreeze function, if a fault occurs, the corresponding
fault is reported and the corresponding code is displayed. After 15 minutes, the system
automatically clears the fault code. If the freeze protection start condition is still met,
the anti-freeze will start again.
9.0 Antifreeze system
No valve is to be placed between the relief valve and water heater. The discharge
from temperature and pressure relief valves will be via the supplied discharge
hose.
Do not obstruct the discharge hose.
DANGER!

for long period. (For specific operations, see "
Drain and Store Instructions ")
Add antifreeze recommended by the RV manufacturer.
Start the antifreeze function to prevent freezing. Turn on the power switch and
the gas valve, turn off the water inlet. The water heater will be on antifreeze mode
automatically (please ensure there is enough gas in the RV).
