Turning on/off a wall-hung boiler calls for following the principle of "check first, then operate". correct steps can keep away from safety risks and protect the gadget—novices also can cope with it without difficulty by using following the technique～
I. Step 1: take a look at before Turning On, ensure protection
First, do two simple exams: one is to see if the fuel valve is open (the knob is parallel to the pipeline for "on"); the boiler can not begin without gasoline. the second is to take a look at the water pressure gauge—if the pointer is between 0.1-0.2MPa, it is regular; if it's miles decrease than 0.1MPa, upload water first (twist open the water filling valve until it reaches the ordinary range, then near it) to keep away from dry burning and adverse the system.
II. Step 2: power On and start, operate grade by grade
First, connect the strength supply (plug in the electricity twine or turn on the electricity transfer), then press the "electricity button" (marked ON/OFF) on the frame. The boiler begins efficaciously while the display display screen lights up or the green indicator light is on. If heating or hot water is needed, press the "mode button" to interchange to the corresponding mode after starting (heating is marked with a radiator icon, warm water with a faucet icon); if no mode operation is needed at once, it can stand via first.
III. Step three: Shutdown Steps, perform with the aid of state of affairs
brief-time period shutdown (e.g., not the usage of it the same day): Press the "electricity button" to turn off at once, and disconnect the strength supply after the display is going out; lengthy-term shutdown (e.g., now not the usage of it in off-seasons): First turn off the mode (if it's miles in operation), press the strength button to close down, then near the gas valve and important electricity deliver. ultimately, after checking for no fuel leakage or water leakage, clean up particles across the boiler frame.
IV. Step four: Precautions for On/Off, avoid problems
Do now not touch the boiler body right away after turning it on (the shell is warm for the duration of operation); if restart is wanted after shutdown, wait five mins earlier than turning it on (to defend internal components); if a fault code (together with E1) appears on the show-prepared version, first check the fuel/water pressure. Do no longer disassemble or restore it yourself if the trouble can't be solved—contact after-income provider to make certain safe on/off operation without dangers.
