SERVICING PRECAUTIONS

Air Recharging in Compressor

Test the refrigeration by connecting itelectrically before
refilling operation. It is necessary to ascertain the function

of the motor*compressor and identify the defects
immediately. If the defects have been found, empty the old

system of eventual R-12 residue by breaking off the end of
the extension piece at its narrow point. (Figure 1)

Replace the filter and any damaged components. Unsolder
and pull off the piece remaining inside the service tube and
then attach an extension completely with male Hansen and
last, solder it to the same tube again. (Figure 2)

It is necessary to execute the soldering operation with
valve open so that the fumes caused by oil residue can
come out freely without blowholes between two tubes

The extension fitted with the male Hansen is connected to

the female fitting of the vacuum pump tube. (Figure 3)

Before performing this operation (if the vacuum pump and

refilling cylinder are connected), make sure that the valve

placed between the vacuum pump and refilling tube are
closed to keep the Freon for adding to the system. (Figure 5)

Air evacuating from the system begins so soon as the

vacuum until the reading on the low-pressure gauge
indicates vacuum (0 absolute, -1 atm., -760 mm hg) in any
case it is advisable to keep the pump running for about 60
minutes. (Figure 3)

vacuum pump will be necessary and add a small quantity
of Freon to the system, if vacuum should not be obtained
(pressure gauge can't fall to 1 atmosphere), start the
refrigeration unit and find the leakage with the special leak-
finder. When the defective soldering point is visible, re-do it
after opening the extension tube valve and reestablishing
the normal outside pressure inside the group.

Because the melted alloy is sucked into the tubes and
block them, the pressure must be rebalanced when
vacuum is in the system in soldering. As soon as the

In addition, check the graduated scale on the cylinder for
the quantity of R-12 to be added, for example, if we have

750 grams of Freon in the cylinder and must add 165
grams to the group, this amount will be reached when

R-12 has dropped to 585 grams, remembering that the

indicator shows a lower limit of meniscus. Do this after
choosing the scale corresponding to the gas pressure

different scales reported as the same gas pressure

indicated by the pressure gauge on the top of the column.
To make R-12 flow into the system, open the valve placed

at the base of the cylinder and connected to the filling tube.
The amount of Freon cannot be added to the system all at
once because it may cause a blocking of

motor-compressor. Therefore, proceed by adding original
quantity of about 20-30 grams and close the valve

immediately.
The pressure rises and the motor-compressor must start,

sucking the gas and making the pressure go down again.

Regulate the valve again, maintaining the same manner

until reaching to the quantity of R-12 established for the
system being charged. When the system is running, the
suction pressure must be stabilized between 0.10 to 0.4
atmosphere.

Test the refrigeration by connecting it electrically before

of the motor*compressor and identify the defects

of the extension piece at its narrow point. (Figure 1)

and pull off the piece remaining inside the service tube and
then attach an extension completely with male Hansen and
