The work should be done before installing a gauge on the high-pressure side of a system.

Answer to Problem 1RQ

The work should be done before installing a gauge on the high-pressure side of a system is turn off the system.

Explanation of Solution

The pressure gauge is an instrument used to measure the gauge pressure of the flow of fluid. It displays high and low pressure side of the system when it is put in operation. This used to convert the pressure of the system different refrigerant requirements.

The technician should be skilled to attach the manifold gauge. Attaching the gauge to the manifold should be done very carefully. Wearing goggles and gloves are necessary while attaching the gauge otherwise the high-pressurised refrigerant can injure to eyes and skin of technician.

This type of dangerous condition can be prevented by letting the pressure of high-pressure side refrigerant down to lower pressure. To reduce the pressure to lower pressure, the system should be turned off.

Conclusion:

Hence, the work should be done before installing a gauge on the high-pressure side of a system is turn off the system.
