10th. When the correct weight of refrigerant has been charged, close the LO valve.
11th. When the equipment is functioning according to the specified working conditions, close the valve of the
charging bottle and disconnect the tubes taking precautions regarding gas purge.
12th. Place the caps on the supply and return lines of the compressor.
Detecting Leaks:
⋅ Symptoms of gas leaks.
Leaks will cause a decrease in the refrigerant charge in the equipment. Low refrigerant charge may be the caused by
⋅
the following symptoms:
The evaporating temperature is very low. This may be also caused by an obstructed fluid line or the
1.
incorrect operation of the expansion valve.
2. The compressor is functioning on cycles which are too short.
Compressor is overheated: Gas leaks cause gas flow to be insufficient to cool the compressor. This may
3.
cause the tripping of the internal thermostat of the compressor.
4. The compressor operates continuously, there is not enough refrigerant to obtain the desired power, and
since the specified temperatures are never reached, the unit never shuts down.
⋅ In any case, it is better not to wait until a leak appears and service regularly the circuit.
Methods for Searching for a Gas Leak:
There are various tools on the market used in order to detect leaks, although not all of them are sufficiently sensitive
⋅
to certain types of refrigerants. It is very important to choose an adequate detector for the refrigerant used for this
equipment and that the maintenance guidelines by followed.
⋅ You can also use soap bubbles (liquid detergent in a spray bottle) to detect leaks.
⋅ Other methods such as halogen lighters and additives may also be used to detect leaks.
The R-407-C Gas:
⋅ The R-407-C is a NONFLAMMABLE gas; it has no flash point, and so is not subjected to the rules and regulations of
the transportation of inflammable gases.
⋅ The R-407-C does not irritate the skin, eyes or mucous membranes and does not produce and side-effects.
⋅ It has a very low level of toxicity for one or many repeated exposures; it does not cause cancer or mutations.
⋅ The R-407-C may cause freezing if it comes into contact with the skin, due to its immediate evaporation.
⋅ As with all hydrocarbons, whether they are halogenated or not, the R-407-C gas may, although it has a very low level
of toxicity, cause anaesthetic or preanaesthetic conditions if inhaled deeply and within a closed area.
