<The system for air tight test and vacuum drying>
• Referring to figure 29, connect an nitrogen tank, refrigerant tank,
and a vacuum pump to the outdoor unit and function unit.
The refrigerant tank and the charge hose connection to refrigerant
charge port or the valve A in figure 29 are needed in “
9. ADDI-
TIONAL REFRIGERANT CHARGE AND CHECK OPERATION
”.

<Air tight test>
Pressurize the liquid pipe, gas pipe and the equalizer pipe (for the
multi outdoor unit system only) from the each shutoff valve ser-
vice ports of outdoor unit and the service ports of function unit to
4.0 MPa (40 bar) (do not pressurize more than 4.0 MPa (40 bar)).
If the pressure does not drop within 24 hours, the system passes
the test.
If there is a pressure drop, check for leaks, make repairs and per-
form the airtight test again.
<Vacuum drying>
Evacuate the liquid pipe, gas pipe and the equalizer pipe (for the
multi outdoor unit system only) from the each shutoff valve service
ports of outdoor unit and the service ports of function unit by using
a vacuum pump for more than 2 hours and bring the system to
–100.7 kPa or less. After keeping the system under that condition
for more than 1 hour, check if the vacuum gauge rises or not. If it
rises, the system may either contain moisture inside or have leaks.
Note
[Airtight test and vacuum drying while in Evaculation mode setting]
When all the electrical work on the system including the indoor unit is
finished and it is safe to supply power to the system, turn ON the
entire system and set the Evaculation mode setting (service mode)
through the PCB (A1P) of the outdoor unit. All the connection piping
and indoor unit excluding the equalizer piping can be airtight tested
and vacuum dried through the liquid pipe service port of the function
unit. Furthermore, refrigerant charging through the liquid piping is
possible while the system is not in operation. Refrigerant charging is
not possible while the system is in operation.
For the details of the Evaculation mode setting, refer to the [Service
precautions] label (below) on the EL.COMPO.BOX lid of the outdoor
unit.
If moisture might enter the piping, follow belows.
(I.e., if doing work during the rainy season, if the actual work
takes long enough that condensation may form on the inside of
the pipes, if rain might enter the pipes during work, etc.)
(1) After performing the vacuum drying for two hours, pressurize to
0.05 MPa (i.e., vacuum breakdown) with nitrogen gas, then
depressurize down to –100.7 kPa for an hour using the vacuum
pump (vacuum drying).
(2) If the pressure does not reach –100.7 kPa even after depressur-
izing for at least two hours, repeat the vacuum breakdown - vac-
uum drying process.
(3) After then, maintain the vacuum for an hour and make sure the
pressure does not rise by monitoring with a vacuum gauge.
8-2 Pipe insulation
• Insulation of pipes should be done after performing “8-1 Air tight
test and vacuum drying”.
• Always insulate the liquid pipe, gas pipe and equalizer pipe (the
piping between the outdoor units in the case of the multi outdoor
unit system) and these pipe connections. Failing to insulate the
pipes may cause leaking or burns.
And be sure to use the insulation which can withstand such tem-
peratures of 120°C or more for the gas piping because the high
pressure gas follows in these pipings.
• Thermal insulate the liquid pipe and gas pipe of the function unit
up to the point immediately before the piping support in the func-
tion unit. (Refer to figure 30)
• If there is a possibility that condensation on the shutoff valve
might drip down into the indoor unit through gaps in the insulation
and piping because the function unit is located higher than the
indoor unit, etc., this must be prevented by caulking the connec-
tions, etc. (Refer to figure 30)
(Refer to figure 30)
1. Piping support
2. Gas pipe (to outdoor unit)
3. Liquid pipe (to outdoor unit)
4. Thermal insulator end (4 points)
5. Perform caulking processing.
6. Liquid pipe (to indoor unit)
7. Gas pipe (to indoor unit)
• Reinforce the insulation on the refrigerant piping according to the
installation environment. Condensation might form on the surface
of the insulation. Refer to the below.
Ambient temperature : 30°C, humidity : 75% to 80% RH : min.
thickness : 15mm.
If the ambient temperature exceeds 30°C and the humidity
80% RH, then the min. thickness is 20mm.
See the Engineering data book for detail.
• The piping lead-out hole lid should be attached after opening a
knock hole.
If small animals and the like might enter the unit through the pip-
ing lead-out hole, close the hole with blocking material (procured
on site) after completion of “9. ADDITIONAL REFRIGERANT
CHARGE AND CHECK OPERATION”. (Refer to figure 31)
(Refer to figure 31)
1. Piping lead-out hole lid
2. Open a knock hole at “ ”.
3. Block “ ”.
Note
• After knocking out the holes, we recommend you remove burrs in
the knock holes (See figure 31) and paint the edges and areas
around the edges using the repair paint.
8-3 Checking of device and installation conditions
Be sure to check the followings.
For those doing electrical work
1.
Make sure there is no faulty transmission wiring or loosing of a nut.
See “
7-4 Transmission Wiring Connection Procedure
”.
2.
Make sure there is no faulty power wiring or loosing of a nut.
See “7-5 Power Wiring Connection Procedure”.
3.
Has the insulation of the main power circuit deteriorated?
Measure the insulation and check the insulation is above regular
value in accordance with relevant local and national regulations.
Prohibition
Do not use a insulation resistance tester to light electric circuits (e.g.,
transmission wire terminals between outdoor and indoor units).
