Manual

Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed

the permissible voltage and current permitted for the equipment in use. Intrinsically safe components are the only

types that can be worked on while live in the presence of a ﬂammable atmosphere. The test apparatus shall be at

the correct rating. Replace components only with parts speciﬁed by the manufacturer. Other parts may result in the

ignition of refrigerant in the atmosphere from a leak.

8.Repair to intrinsically safe components

10.Detection of ﬂammable refrigerants

The following leak detection methods are deemed acceptable for systems containing ﬂammable refrigerants.

Electronic leak detectors shall be used to detect ﬂammable refrigerants, but the sensitivity may not be adequate,

or may need re-calibration. (Detection equipment shall be calibrated in a refrigerant-free area.)

Ensure that the detector is not a potential source of ignition and is suitable for the refrigerant used. Leak detection

equipment shall be set at a percentage of the LFL of the refrigerant and shall be calibrated to the refrigerant

employed and the appropriate percentage of gas (25 % maximum) is conﬁrmed.

11.Leak detection methods

Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other

adverse environmental eects. The check shall also take into account the eects of aging or continual vibration

from sources such as compressors or fans.

9.Cabling

Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant

leaks. A halide torch (or any other detector using a naked ﬂame) shall not be used.

When breaking into the refrigerant circuit to make repairs or for any other purpose conventional procedures shall

be used. However, it is important that best practice is followed since ﬂammability is a consideration. The following

procedure shall be adhered to: Remove refrigerant; Purge the circuit with inert gas; Evacuate; Purge again with

inert gas; Open the circuit by cutting or brazing.

The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be ﬂushed with

OFN to render the unit safe. This process may need to be repeated several times. Compressed air or oxygen shall

not be used for this task.Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing

to ﬁll until the working pressure is achieved, then venting to atmosphere, and ﬁnally pulling down to a vacuum.

12.Removal and evacuation

Leak detection ﬂuids

are suitable for use with most refrigerants but the use of detergents containing chlorine shall be avoided as the

chlorine may react with the refrigerant and corrode the copper pipe-work. If a leak is suspected, all naked ﬂames

shall be removed/extinguished. If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall

be recovered from the system, or isolated (by means of shut o valves) in a part of the system remote from the

leak. Oxygen free nitrogen (OFN) shall then be purged through the system both before and during the brazing

process.

Does every air conditioner also function as a dehumidifier? Verified

The cold air produced by an air conditioner often has a relatively low humidity. However, the effect is less than when using an actual dehumidifier. Some air conditioners do have a special feature to dehumidify the air.

What is R-410A? Verified

R-410A is a cooling agent that is used in appliances that cool up to 0°C, like refrigerators and air conditioners. It is the replacement of older cooling agents and does not damage the ozon layer.

Does an air conditioner have a negative influence on air quality? Verified

If the air conditioner has been properly maintained then it will have no influence on air quality. If for example a filter hasn't been replaced for a long time, or other maintenance has not been performed, than an air conditioner can produce dirty air.
