H. Avoid random movement of control panel function keys
There are many buttons on the control panel of the host, some of which are used to adjust the water temperature, some of which are timed. If the user moves around, it is likely to affect the normal operation of the host. For example, if the timing key is pressed, the host may not start when it needs to work.
During the installation, the installation personnel will set the water temperature and tell the user which keys can be moved and which keys should not be moved randomly. Generally, the user only needs to adjust the outlet temperature. When the indoor temperature is not enough, the outlet temperature will be raised a little. If the indoor temperature is too hot, the water temperature will be lowered.
When the machine is stopped for a long time, the machine shall be sealed for maintenance, and the water in the water pump and the whole water pipeline shall be drained to prevent freezing crack of the water pump and water pipeline, and the water shall be drained from the lowest drain of the water pump and the casing heat exchange. If the unit has been shut down for a long time, the following preparations shall be made when it is started again: thoroughly check and clean the unit; clean the water pipeline system; check the water pump, regulating valve and other equipment of the water pipeline system; check whether all wire connections are tight.
The most important point: if you start the machine for the first time in cold winter, please power on and preheat for more than 12 hours in advance. Do not add water to the system during preheating. After preheating, let the water pump warm up first, and then start the pump to make up water.
If there are damaged parts on the unit that need to be replaced, it is necessary to contact the corresponding manufacturer of the unit for purchase. The original parts of the company shall be used instead of any different parts. As the saying goes, the original is the best. If you replace other parts of different models, it may cause incompatibility between the unit and the parts, or even burn them.
