Junkers Cerapur smart -3 - low pressure, use the valve to add water

Hello, low pressure on the clock, the needle is already entering the red field, use the valve to allow water to the correct pressure.

Upload a photo of the bottom of the stove, someone will explain it to you because in the present way, how? Or it is also described in the manual.

The question is not very precise because there is no smart model. As for the ZWB28-3C model, there should be a thin black or brown plastic handle on the bottom on the left side, turn 1/4 turn. If it is missing, it has been lost or not installed. On the other hand, the versions of the ZSB22 ... ZSB14 ... boiler are approved outside, on the system, usually two valves connected with a hose ... or a permanent connection through a check valve.

Unfortunately, you probably look for a water intake for free in this model. Possible external discharge. After the hardware, I feel that this is the Benelux version. Give the device's catalog number exactly. I have a feeling that this is not a production for Poland.

Hello, this is the furnace in Belgium, hit the 10th. I am sending a photo.

Very little space for the phone so a bit poor

The Polish version of this ZWBR35-3E boiler has a water inlet. On the other hand, in this version of ZWB42-3A, you should look for a regulation for free, because there is no. You have to look for an external valve or valves (sometimes there are two or a separable hose) that are permanently closed. If you can, take a photo of the external valves that are not included in this photo. The chilled water enters the Junkers fourth from left to right with this angled twist valve. Follow the water route if there is no valve that would allow connection to the central heating system or combine a hose, e.g. a park hose, which you could add water to. The pressure on the pressure gauge is actually too low.

It is difficult to clearly determine what to turn on to replenish the water to the system. I wonder if this is not the route connected with a flexible armored hose, the valve on the route is open at the top and at the bottom? Further to the brass manifolds on the left some valves are closed, why? Further on the wall on the left there is a closed valve without connection with an external thread, it is not known whether it is a water drain or the possibility of connecting a hose? .. You need to recognize the cold water route to determine how to make a connection with the system ... free valve with thread. Such a solution where the system is filled outside the boiler, the valves should be described, because water is allowed sporadically, and secondly, instead of pouring water into the system, we can accidentally drain it. Further, without a non-return valve, water that may enter the drinking water.

Hello, this soft conduit is connected (power) to the geberit in the toilet, I took a picture from the top, first No. 1 next to the stove, and the second No. 2 are the wires on the second wall next to it, maybe now you will see something better. Greetings.

In photo 2 you can see the connection with the hose on the left side there is a valve along the pipe open and on the right side closed across. Try to gently open the valve while observing the pressure on the junker. If the pointer does not move up, close it.

Hello, after trying, unfortunately, nothing happens on the clockwork, but I have such a thought when I look at this valve with a soft hose and I would connect it to the threaded valve and open the water, because the soft hose is cold and the one with the thread is hot, now I would just need a hint whether to add water while the stove is off, or if I can add water while it is running. Greetings.

Turn the water valve in front of the hose, unfasten it and try to move the hose to the threaded valve, do not tighten it for good yet. After connecting, remove air from the hose, then tighten the nut. Let the boiler work and gently unscrew one of the valves and dose with the other one, carefully observing the pressure on the pressure gauge. Should increase if the idea is hit. If the needle twitched down, turn and return to the starting point.

Hello, the action was successful, I raised the pressure, but for a long time it was really going, the tip didn't even twitch, it just rose slightly, the most important thing is that the problem is solved. Thank you very much for your help and best regards. I'm sending a photo of the clock.

I'm glad you made it. I am surprised that this admission of water is so difficult to read. In Poland, a plumber usually installs two valves that are connected with a hose.
