My hot water is too hot. So I looked at the heater and it has stickers on the side that say in red "disconnect power supply before removing panel to adjust temperature." Why do I have to disconnect the electric first? It's just a panel and thermostat, right? It's hard wired, not plugged in. Thanks

You have many potential things to check: 1) What type of heater is it, gas, oil or electrical? 2) What is the capacity of the tank ? or is it tankless ? 3) How many minutes of shower time are you talking about, 20 minutes or two hours ? 4) Is the shower head a water-saver, or does it flow fast ? If the tank is about 40 gallons, is electric and the shower head is a water-saver, you probably should get about an hour of shower time, unless one element is burned out. It also depends on the hot water temperature setting at the tank. Most are factory set, but some people turn down the temperature to 'save' money, then only turn on the HOT tap, which will empty the hot water tank very fast. Do your homework, and if you don't own the place, ask the landlord !

By disconnect power they mean " interrupt the power supply to the waterheater" which you can do simply by turning off the breaker to the water heater.
Why? Safety...you don't want to take the chance of getting a serious shock do you? Especially, in any environment that contains both " water and electricity."

Throwing the breaker is the safe way to adjust the temperature. If you are comfortable sticking a metal screwdriver near hot circuits, then go ahead, but the breaker panel is there for this reason also.

If your water level happens to drop below the first thermal controller and it instantly tries to heat up, you could destroy that thermal unit. Expect around $50 for a new one (not installed) if you decide to install it yourself you will need to purchase a special wrench also. My advice? Take to 10 seconds, kill the breaker for the heater, adjust it, hit the breaker back on. Not to mention the personal dangers listed above.

There should be a thermostat u can adjust on the outside of the tank.

You can pull the breaker in your breaker box just to be on the safe side. It's better to be safe than sorry when dealing with electricity.

How old is this thing, usually the adjustment knob is on the outside of the unit.

The stickers are there so that if you get electrocuted, they cannot be sued.
