Step 1….Pressurize to 0.5 MPa (5 kg/cm²G) for 5 minutes or longer. Step 2….Pressurize to 1.5 MPa (15 kg/cm²G) for 5 minutes or longer.

Major leaks can be discovered.

Step 3….Pressurize to 4.15 MPa (42 kg/cm²G) for 24 hours. ……………. Micro leaks can be discovered.

(However, note that when the ambient temperature differs during pressurization and after 24 hours, the pressure will change by approximately 0.01 MPa (0.1 kg/cm²G) per 1°C, so this should be compensated.)

If the pressure drops in steps 1 through 3, check the connections for leakage.

• After the airtight test is completed, evacuate the nitrogen gas.

Air purge
With respect to the preservation of the terrestrial environment, adopt “Vacuum pump” to purge air (Evacuate air in the connecting pipes) when installing the unit. y Do not discharge the refrigerant gas to the
atmosphere to preserve the terrestrial environment. y Use a vacuum pump to discharge the air (nitrogen,
etc.) that remains in the set. If air remains, the capacity may decrease. For the vacuum pump, be sure to use one with a

pump stops. (If oil in the vacuum pump is put in an air conditioner including R32, it may cause trouble with the refrigeration cycle.)

Gas leak inspection
Use a leak detector manufactured specially for HFC refrigerant (R32, R410A, R134a, etc.) to perform the R32 gas leak inspection.

• Leak detectors for conventional HCFC refrigerant (R22, etc.) cannot be used, as the sensitivity drops to approximately 1/40 when used for HFC refrigerant.
  y R32 has a high working pressure, so failure to perform the installation work properly may result in gas leaks such as when the pressure rises during operation. Be sure to perform leak tests on the piping connections.

Insulating the Pipes
y The temperatures at both the liquid side and gas side will be low during cooling so in order to prevent condensation, be sure to insulate the pipes at both of these sides.
y Insulate the pipes separately for the liquid side and gas side.
y Insulate the branch pipes by following the instructions in the installation manual provided with the branch pipe kit.

REQUIREMENT
Be sure to use an insulating material which can withstand temperatures above 120°C for the gas side pipe since this pipe will become very hot during heating operations.

WARNING
Be sure to connect the earth wire. (grounding work) Incomplete grounding may cause an electric shock.
Connect the earth wire properly following applicable technical standards. Connecting the earth wire is essential to preventing electric shock and to reducing noise and electrical charges on the outdoor unit surface due to the high-frequency wave generated by the frequency converter (inverter) in the outdoor unit. If you touch the charged outdoor unit without an earth wire, you may experience an electric shock.

8 Finishing

clamp them to the wall with off-the-shelf support brackets or their equivalent. Keep the power wires and system interconnection wires off the valve on the gas side or pipes that have no heat insulator.

9 Test run

y Turn on the leakage breaker at least 12 hours before starting a test run to protect the compressor during

startup.

To protect the compressor, power is supplied from the 380-415 VAC input to the unit to preheat the compressor.

y Check the following before starting a test run:

y That all pipes are connected securely without leaks.

y That the valve is open.

If the compressor is operated with the valve closed, the outdoor unit will become overpressurized, which may

damage the compressor or other components.

If there is a leak at a connection, air can be sucked in and the internal pressure further increases, which may

cause a burst or injury. y

Annual maintenance

For an air conditioning system that is operated on a regular basis, cleaning and maintenance of the indoor / outdoor units are strongly recommended. As a general rule, if an indoor unit is operated for about 8 hours daily, the indoor / outdoor units will need to be
person. Failure to clean the indoor / outdoor units regularly will result in poor performance, icing, water leaking and even compressor failure.

the existing pipes and

the reliability of

the pipe strength are conventionally referred to the

local site.

If the

conditions can be cleared, it is

possible to update existing R22 and R410A pipes

to those for R32 models.

Basic conditions needed to reuse existing pipes
Check and observe the presence of three conditions in the refrigerant piping works. 1. Dry (There is no moisture inside of the pipes.) 2. Clean (There is no dust inside of the pipes.) 3. Tight (There are no refrigerant leaks.)

Restrictions for use of existing pipes
In the following cases, the existing pipes should not be reused as they are. Clean the existing pipes or exchange them with new pipes. 1. When a scratch or dent is heavy, be sure to use
new pipes for the refrigerant piping works. 2. When the existing pipe thickness is thinner than the

use new pipes for the refrigerant piping works. y The operating pressure of R32 is high. If there is
a scratch or dent on the pipe or a thinner pipe is used, the pressure strength may be inadequate, which may cause the pipe to break in the worst case. * Pipe diameter and thickness (mm)

y In case the pipe diameter is Ø12.7 mm or less and the thickness is less than 0.7 mm, be sure to use new pipes for the refrigerant piping works.
3. When the outdoor unit was left with the pipes disconnected, or the gas leaked from the pipes and

y There is the possibility of rain water or air, including moisture, entering the pipe.

4. When refrigerant cannot be recovered using a refrigerant recovery unit. y There is the possibility that a large quantity of dirty oil or moisture remains inside the pipes.
5. When a commercially available dryer is attached to the existing pipes. y There is the possibility that copper green rust has been generated.
6. When the existing air conditioner is removed after refrigerant has been recovered. Check if the oil is judged to be clearly different from normal oil. y The refrigerator oil is copper rust green in color: There is the possibility that moisture has mixed with the oil and rust has been generated inside the pipe. y There is discolored oil, a large quantity of residue, or a bad smell. y A large quantity of shiny metal dust or other wear residue can be seen in the refrigerant oil.
7. When the air conditioner has a history of the compressor failing and being replaced. y When discolored oil, a large quantity of residue, shiny metal dust, or other wear residue or mixture of foreign matter is observed, trouble will occur.
8. When temporary installation and removal of the air conditioner are repeated such as when leased etc.
9. If the type of refrigerator oil of the existing air conditioner is other than the following oil (Mineral oil), Suniso, Freol-S, MS (Synthetic oil), alkyl benzene (HAB, Barrel-freeze), ester series, PVE only of ether series. y The winding-insulation of the compressor may deteriorate.
NOTE
The above descriptions are results have been
our air conditioners, but do not guarantee the use of the existing pipes of air conditioners that have adopted R32 in other companies.

Branching pipe for simultaneous operation system
In the concurrent twin system, when TOSHIBA has

reused. Branching pipe model name: RBC-TWP30E2, RBC-TWP50E2, RBC-TRP100E On the existing air conditioner for simultaneous operation system (twin, triple system), there are cases

compressive strength. In such case, please change the piping to a branch pipe for R32/R410A.

Curing of pipes
When removing and opening the indoor or outdoor unit for a long time, cure the pipes as follows: y Otherwise rust may be generated when moisture or
foreign matter due to condensation enters the pipes. y The rust cannot be removed by cleaning, and new
pipes are necessary.

However, since it contains more than air, it poses the risk of suffocation if its concentration should rise excessively. Suffocation from leakage of R32 is almost non-existent. If a conditioner system is to be installed in a small room, select a suitable model and installation procedure so that if the refrigerant accidentally leaks out, its concentration does not reach the limit (and in the event of an emergency, measures can be made before injury can occur). In a room where the concentration may exceed the limit, create an opening with adjacent rooms, or install mechanical ventilation combined with a gas leak detection device. The concentration is as given below.
