When expecting more swimmers in the pool than usual, a higher dosage of chlorine is suggested. This is because chlorine is a disinfectant that helps kill bacteria and other microorganisms in the water. When there are more people in the pool, there is a higher chance of introducing contaminants into the water, such as sweat, oils, and urine. Increasing the dosage of chlorine helps maintain a safe and clean swimming environment by effectively sanitizing the water and preventing the spread of germs.

What is one purpose of shutoff valves on the compressor during installation and when servicing?

Too allow you to overheat the compressor to check for leaks

Too allow the freon to be saved while servicing the unit

Too regulate or shut-off electrical current to the condensor

None of the above

Shutoff valves on the compressor are installed and used during servicing to allow the freon to be saved. By shutting off the valves, the flow of freon can be stopped, preventing any leaks or loss of the refrigerant. This allows for efficient servicing and maintenance of the unit without wasting the freon.

A single burner on a range will not come on. How do you check to see what is wrong?

Ohm out the burner that is not coming on

Replace the burner

Replace the thermostat

Reset circuit breaker

To check what is wrong with a burner that is not coming on, you can use an ohmmeter to measure the resistance of the burner. If the resistance is very high or infinite, it indicates that the burner is faulty and needs to be replaced. This test helps determine if the issue lies with the burner itself rather than other components like the thermostat or circuit breaker. Therefore, ohming out the burner is a suitable method to troubleshoot and identify the problem.

After changing out an element on a water heater, you should always do what before turning the circuit breaker back on?

Fill out the warranty forms

Set the thermostat

Fill the tank with water

All of the above

Before turning the circuit breaker back on after changing out an element on a water heater, it is important to fill the tank with water.

An iced up evaporator is usually a sign of insufficient air through the evaporator coils or:

Low charge

High charge

None of the above

All of the above

An iced up evaporator is usually a sign of low charge. When there is insufficient refrigerant in the system, the evaporator coils do not receive enough refrigerant to properly absorb heat from the air. As a result, the temperature of the evaporator coils drops below freezing, causing moisture in the air to freeze and form ice on the coils. This can lead to reduced cooling efficiency and potentially damage the compressor if not addressed.

A resident calls and complains that soap bubbles run out of the dishwasher when she runs it. A probable cause is:

The drain is clogged

The resident used hand dishwashing soap instead of automatic dishwashing soap

Thd dishwasher is to full

All of the above

The most probable cause for soap bubbles running out of the dishwasher is that the resident used hand dishwashing soap instead of automatic dishwashing soap. Hand dishwashing soap creates more suds and is not designed for use in dishwashers, which can lead to excessive sudsing and overflow. The other options, such as a clogged drain or the dishwasher being too full, can also cause issues, but using the wrong type of soap is the most likely cause in this scenario.

Why is there a delay in restarting a compressor that has kicked off due to an internal overload?

Breaker has tripped

Unit must cool off

Sequencer is out of sequence

All of the above

The delay in restarting a compressor that has kicked off due to an internal overload is because the unit must cool off. When the compressor overheats and shuts off, it needs time to cool down before it can be safely restarted. This cooling off period allows the compressor to avoid further damage and ensures that it operates efficiently when it is restarted.

How many 4 inch x 4 inch ceramic tiles would it take to cover a 120 square foot area?

360

720

1080

None of the above

To find the number of tiles needed to cover a 120 square foot area, we need to convert the area to square inches. Since there are 12 inches in a foot, the area in square inches would be 120 * 12 * 12 = 17,280 square inches. Each tile is 4 inches by 4 inches, so the area of one tile is 4 * 4 = 16 square inches. To cover the entire area, we would need 17,280 / 16 = 1,080 tiles. Therefore, the correct answer is 1080.

This is because a break or leak in the supply line that connects the toilet to the water source can cause water to continuously run out of the wall behind the toilet. This can happen if the supply line gets damaged or develops a leak, allowing water to escape and flow out of the wall.

What causes the burner flame on a gas stove to be yellow?

High gas pressure

Too much air in the flame

Not enough air in the flame

All of the above

When the burner flame on a gas stove is yellow, it indicates that there is not enough air in the flame. This can happen when the air-to-gas ratio is imbalanced, with an excess of gas and insufficient air. The incomplete combustion of the gas results in a yellow flame, as opposed to a blue flame which indicates complete combustion.

If the suction side of a condensing unit has ice on it, what does this mean?

The compressor isn't running

The unit is undercharged

The unit is overcharged

None of the above

If the suction side of a condensing unit has ice on it, it means that the unit is undercharged. When a unit is undercharged, there is not enough refrigerant in the system, causing the temperature to drop below freezing point and resulting in the formation of ice on the suction side. This can lead to reduced cooling capacity and potential damage to the compressor if not addressed.

If a dishwasher hums, but the motor will not run, the probable cause is:

The fill valve solenoid is malfunctioning

The seal is frozen

The timer is malfunctioning

The wrong type of soap was added

If a dishwasher hums but the motor will not run, the probable cause is that the seal is frozen. When the seal is frozen, it prevents the motor from running properly.
