Winter has arrived, and everyone's warm and anti-freeze equipment is also "armed to the teeth" to resist large-scale cooling and extreme weather that may occur at any time. In the face of the severe cold outdoors, have you also taken anti-freezing measures for various electrical appliances that are responsible for plumbing tasks at home? A century-old ao.Smith helps tens of millions of families around the world survive every coldest day. If you happen to not know exactly how to protect your plumbing appliances from freezing, you might as well listen to Ao.Smith's suggestion
Gas water heaters.
The gas water heater should be one of the "heavy equipment" to provide daily bathing and even domestic water for most families, so it is also the first plumbing appliance that needs to be considered for frost protection. a.o.Smith maintenance engineer suggests: For anti-freeze gas water heaters, users need to keep electricity, water and ventilation to ensure that the anti-freeze function is activated normally during daily use; If the conditions in the home cannot ensure electricity and ventilation, the user needs to carry out regular drainage operations; If it is not used for a long time, drain the remaining water in the water heater and turn off the power and air supply. Non-freeze-proof gas water heaters should be paid special attention, such as short-term (about 24 hours) not in use, be sure to close the water inlet valve; If the minimum temperature reaches below zero, or the user wants to go out for a long time, it is necessary to empty the remaining water in the water heater and turn off the power and gas source, otherwise it will cause irreversible damage.
Heating wall-hung boiler.
Due to the full use of space and relatively mature technical performance, more and more families choose heating wall-hung boilers as the first choice for winter heating. Although it has automatic anti-freeze function on its own, it also needs to be noted given the different climatic conditions in different places. In the non-cold southern region, the wall-hung boiler needs to keep the water, electricity and gas sufficient and unblocked, and it will automatically start the antifreeze function according to the water temperature in the furnace, focusing on protecting the furnace body and taking into account the entire heating system; When not used for a long time, in order to prevent the wall-hung boiler from freezing and damage, please follow ao.Professionals such as Smith Maintenance Engineers drain the heating lines and hot and cold water lines in the wall-hung boiler. And in the cold regions of the north (without mining heating, the room temperature can drop below 0 ° C), ao.Smith maintenance engineers recommend using room temperature antifreeze and turning on the wall-hung boiler for heating - with room temperature control, the room temperature can be set to 5-10°C; If there is no room temperature control function, it is necessary to open all the terminal equipment of the heating system and adjust the heating and water outlet temperature of the wall-hung boiler to the lowest; If it is not used for a long time, it is also necessary to ask a professional to drain all heating pipes and hot and cold water pipes in the room to avoid accidents when reactivating.
Water purifiers. As the core guarantee of household drinking water, water purifiers have become the standard configuration of modern families. In the winter when dripping water into ice, water purification products will also face a severe test. For this, ao.Smith maintenance engineers suggest: the ambient temperature of water purification products should not be lower than 4 °C, if it is not guaranteed, the water inlet valve should be closed, and the power supply should be cut off. Specific to different positioning products, anti-freezing measures will also be different. For example, for the water purifier under the cabinet, it is first recommended to maintain a normal room temperature, if it cannot be guaranteed or go out for a long time, the water inlet valve must be closed and the power supply must be cut off; Before using it again, it is necessary to confirm that the appearance of the machine is normal before connecting the water source and power supply. For the ** water purifier, it is recommended to open the faucet slightly at night under the premise of maintaining normal room temperature, and keep a small amount of water flowing out of the water pipe; If the room temperature cannot be guaranteed or when you go out for a long time, you need to close the water inlet valve and cut off the power supply. As for the simplified version of the pre-filter, it is also recommended to turn the faucet on slightly at night to keep a small amount of water flowing out of the water pipe; If you go out for a long time, you need to close the main water valve, drain the remaining water in the pre-filter, and then turn on any tap faucet, rotate the black knob at the bottom of the pre-filter, and close the knob after emptying the internal residual water.
Water system** air conditioning.
For the ** air conditioner commonly used in mid-to-high-end households, it is also based on the water treatment system, so ao.Smith maintenance engineers pointed out that only under the conditions of water and electricity can it be effectively protected from freezing. In addition, if you are away from home for a long time or the ambient temperature is below 5°C, do not turn off the power of the air conditioning system! Because only in this way, even if there is no one at home, the air conditioner will automatically start the antifreeze protection according to the indoor temperature and outdoor ambient temperature. In case of special circumstances, when the power of the air conditioning system must be turned off, it is recommended that the user do not deal with it by himself, and it is best to ask Ao.In this way, Smiths maintenance engineers visit the professional to professionally drain the air conditioning system ducts, so as to ensure that there are no accidents or even serious damage to the air conditioning system when it is turned on again.
It is the cooperation of these plumbing appliances that allows every family to experience warmth and comfort in winter. If you want them to play a bigger and longer-lasting role, then you might as well help them protect themselves from frost and survive this winter with their families safe and healthy!
