cause side effects as shown below:
- Increased pressure in the system.
- Increased current consumption.
- Decreased refrigerant efficiency
- Freezing and obstruction of the pipes
capillaries.
- Corrosion of the parts of the system of
refrigeration.
To avoid the above, the internal assembly and the
tubes, places between internal and external group,
must be tested for leaks and purged to remove
non-condensing elements and humidity from the
system.
Check that each tube, (is the gas side tubes
that of the liquid) between internal group and
external group, has been connected in the correct
way and that all wiring necessary for testing have
been carried out. Remove the valve cap on the
assembly external. Make sure that both are now
gas and liquid valves remain closed.
Check the length of the tube and its quantity
of the refrigerant, for a correct charge, check the
overheating value. The table values are
indicative.
When you change places in the unit, carry it out
bleeding with the vacuum pump. Make sure the
refrigerant inside the conditioner is always
in liquid state.
The outdoor unit is supplied with a gas charge
R410A refrigerant suitable to guarantee a correct
operation up to a maximum distance of 5 meters
from the indoor unit.
If you decide to install the 2 units at a distance
greater than 5 meters, be sure to add 20 g of
refrigerant gas for each extra meter of pipe (Tab. 3).
For example, if there are external and internal units
7 meters of piping add 40 g of R410A gas.
In any case, never exceed 15 meters.
Do the addition only after making the vacuum in the
pipes that connect the 2 units, such as illustrated in
chapter 3.4, after which you can proceed with the
opening of the gas taps, mounted on board
machine.
3.5 EVACUATION
Connect the end of the charging hose to the
vacuum pump to evacuate the air from the pipes
of the internal unit. Check that the knob
"LO" of the pressure gauge valve is open.
Then run the vacuum pump. The time of
operation varies depending on the length of the
tubes and pump capacity.
When the desired vacuum is reached, close
the "LO" knob on the pressure gauge valve e
stop the vacuum pump. In conclusion, using
a wrench for service valves, rotate the stem
of the gas side valve counter clockwise for
open it completely.
Loosen the charging hose connected to the socket
gas side service to relieve pressure, then
remove the tube. Replace the cover nut on the
gas valve and service outlet and tighten
well with an adjustable wrench.
This procedure is very important to avoid
plant leaks Replace the service valve caps either
on the gas side than on the liquid side and tighten
well.
This completes the air purge procedure with the
vacuum pump, make sure all the pipes are
connected correctly and that the valves of service of
the gas and liquid sides are completely
open.
