Problem: Article: It is highly recommended that a qualified professional refill and recharge your AC unit. The procedure itself is dangerous, and if done incorrectly, you can damage your unit. Homeowners are permitted to add refrigerant in the U.S., but the Environmental Protection Agency (EPA) requires that anyone you hire to do the job have a professional certification. Proceed with caution if you decide to do this yourself. Improper handling of refrigerant can cause injury, death, explosions, and property damage. Go to the thermostat that operates your air conditioner. Turn it to the "off" position. Your unit will either have a fused disconnect or circuit breaker attached to it. If your unit has fuses, disconnect them. If your unit has a circuit breaker, turn the breaker off. There are 3 valve connections attached to your unit's hardware, with a valve on each side (left and right). Attach the gauge with the blue hose to the low-pressure valve on the left side. Attach the gauge with the red hose to the high-pressure valve on the right side. Leave the center valve open for now; that is where you'll connect the yellow hose to feed the refrigerant into the system. After you turn the AC back on, the unit will need to run for several minutes so that it can stabilize itself. You won't get an accurate reading on the refrigerant gauges until the AC has stabilised. Attach the yellow hose to the refrigerant canister's valve and attach the other end to the middle valve connection on your gauge. There will be a small knob on the bottom of the refrigerant canister. Twist it several times to open the refrigerant. The middle valve is the one between the blue and red valve connections. Open it for a few seconds, then close it. Open it for a few more seconds, then close it again. Continue doing this. You want to slowly allow small amounts of the refrigerant into the unit at a time until you reach your target subcooling temperature. The target subcooling temperature is stated on the outdoor unit rating plate. Use the gauge to monitor the temperature so you know when to shut the valve. For example, the rating plate might say something like "10 degree TXV sub-cooling." Once the target subcooling temperature is reached, turn the valve all the way off. Twist the knob on the refrigerant canister to stop refrigerant from going into the hose. Disconnect all of the hoses and the gauge set from the AC unit. Since the unit is running during this process, there's no need to restart your unit after adding refrigerant. You can buy an electronic leak detector at most home improvement stores and online. Each detector is slightly different, but in general you just need to run the tool along the refrigeration components to scan for a leak. If you don't feel qualified to do this yourself, have a certified HVAC technician come out to test the unit for you.
Summary: Consider having a professional perform this procedure. Turn off your AC unit at the thermostat and breaker. Hook up the refrigerant gauges to the valve connections. Turn the AC unit back on and wait about 15 minutes. Open the canister of refrigerant by twisting the spout on the bottom. Open the blue low-pressure valve on the left side. Watch the gauge until you reach the target subcooling temperature. Turn off the valve and disconnect the gauge set. Perform an electronic leak test to ensure safe operation.

Problem: Article: Capricorn men are usually reserved and quiet, but they do open up and show their humorous side with people they really like. If he tells you jokes, teases you, or acts silly when he's around you, it could be a sign he's into you. Next time you see him, try telling him a joke or teasing him and see how he reacts.

If a Capricorn man shares his secrets with you and talks to you about his personal problems, there's a good chance he likes you. If you're always the first person he goes to when something is wrong, it could be a sign that he likes you. Check your texting and social media conversations. Do you exchange short, surface-level messages, or does he talk a lot about what's going on in his personal life? Once a Capricorn man decides he likes someone, he doesn't take well to people getting in his way. If he seems moody or upset whenever you focus your attention on others, it could mean he wishes you were talking to him instead. Pay attention to how he acts when you're talking to others.

They don't let just anyone into their home. If he's inviting you over to his place, it's a sign that he really trusts you. If he gives you rides in his car or lets you use his stuff, it could also be a sign that he trusts and likes you.
Summary: Pay attention to if he jokes around with you a lot. Ask yourself if he confides in you. Notice if he gets jealous when you flirt with other people. Take it as a good sign if he invites you over to his place.

Problem: Article: After you have finished playing the dizi, use a soft cloth to wipe it dry. You may use a long rod to push a cloth inside the dizi to catch excess moisture. Cloth bags, plastic airtight bags, or hard-covered soft-lined cases are ideal containers in which to store a dizi. Bamboo flutes are susceptible to expanding or contracting depending on temperature and humidity. Do not place in direct sunlight such as on a windowsill, as this will likely lead to cracked bamboo. If you are taking the dizi outside on a cold day, allow the flute to acclimatize before playing it. Since moisture may gather in the dizi, even if you've dried it, fungus spores may start to grow. Use food grade hydrogen peroxide to spot clean the flute to eliminate fungus growth. Some flute owners choose to oil their dizis with almond oil 3-4 times per year. It is best to wait until the flute is completely free of moisture (i.e., waiting a day after playing and drying it) before applying oil. Use just a bit of oil and rub it into the dizi with a soft cloth. You may also choose to oil the inside of the flute as well. Allow to dry completely before playing.
Summary:
Wipe the dizi dry after playing. Store the dizi in a dedicated case. Avoid swift temperature changes. Eliminate any growth of fungus. Periodically oil the dizi.
