Do not put pipes on the ground directly without a cap

or vinyl tape at the end of the pipe

If piping installation is not completed until next day

or over a long- er period of time, braze off the ends
of the piping and charge with oxygen free nitrogen
through a Schrader valve type access fi tting to
prevent moisture and particle contamination.

Do not use insulation material that contains NH3

because it can damage cooper pipe material and can
be a source of future leak- age.

Completely insulate both refrigerant gas piping and

liquid piping between the indoor unit(s) and the
outdoor unit.

If not insulated, dew will ocur on the piping surface

18.2 SUSPENSION OF REFRIGERANT
PIPING

Suspend the refrigerant piping at certain points and

Do not loosen the stop ring. If the stop ring is loosened,

it is dan- gerous since the spindle will hop out.

An excess or a shortage of refrigerant is the main

cause of trouble to the units. Charge the correct
refrigerant quantity according to the description of
label at the inside of service cover.

Check for refrigerant leakage in detail. If a large

refrigerant leakage occurs, it will cause diffi culty with
breathing or harmful gases would occur if a fi re was
being used in the room.

Evacuation and refrigerant charge

- Connect the gauge manifold using charging
hoses with a vacuum pump or a nitrogen cylinder to
the check joints of the liquid line and the gas line stop
valve.

- Check for any gas leakage at the fl are nut connection,
by using nitrogen gas to increase the pressure at

4.15 MPa for outdoor units inside of the fi eld-supplied
piping.

- Operate the vacuum pump for 1 to 2 hours until the
pres- sure decreases lower than a pressure of 756
mmHg in vacuum.

- For charging refrigerant, connect the gauge manifold
us- ing charging hoses with a refrigerant charging
cylinder to the check joint of the liquid line stop valve.

- Charge the proper quantity of refrigerant according
to the piping length (Calculate the quantity of the
refrigerant charge).

- Fully open the gas line stop valve, and slightly open
the liquid line stop valve.

- Charge refrigerant by opening the gauge manifold
valve.

- Charge the required refrigerant within the difference
range of ±0.5kg by operating the system in cooling.

- Fully open the liquid line stop valve after completing
refrig- erant charge.

- Continue cooling operation for more than 10 minutes
to circulate the refrigerant.

airtight test. These types of gases are extremely
dangerous, Insulate the unions and fl are-nuts at the
piping connection part completely.

Insulate the liquid piping completely to avoid a

decrease of performance;

if not, it will cause sweating on the surface of the pipe.
Charge refrigerant correctly. Overcharging or

insuffi cient charging could cause a compressor
failure.

Check for refrigerant leakage in detail. If a large

refrigerant leakage occurred, it would cause diffi culty
with breathing or harmful gases would occur if a fi re
were being used in the room.

If the fl are nut is tigthened too hard, the fl are nut may

crack after a long time and cause refrigerant leakage.

18.5 Caution of the pressure by check
joint

When the pressure is measured, use the check joint

of gas stop valve (A), and use the check joint of liquid
piping (B) in the fi gure below.

At that time, connect the pressure gauge according to

the following table because of high pressure side and
low pressure side changes by operation mode.

NOTE

Be careful that refrigerant and oil do not splash to the

electrical parts at removing the charge hoses.

The gas stayed at O-ring
screw part is opened
and may make sound

19. TEST RUNNING

When installation is completed, perform test run

according to the following procedure, and hand
over the system to the customer. Perform test run
regarding indoor units one by one in order, and
confi rm that the electrical wiring and the refrigerant
piping are correctly connected.

Test run should be performed according to the Test

Run Proce- dure on next page.

C A U T I O N

Do not operate the system until all the check points

have been cleared:

• Check to ensure that the electrical resistance
is more than 1 MΩ, by measuring the resistance
between ground and the terminal of the electrical
parts. If not, do not operate the sys- tem until the
electrical leakage is found and repaired. Do not
impress the voltage on the terminals for transmission
1 and 2.

• Check to ensure that the stop valves of the
outdoor unit are fully opened, and then start the
system.

• Check to ensure that the switch on the main
power source has been ON for more than 12 hours,
to warm the compressor oil by the oil heater

Pay attention to the following items while the system

is running:

• Do not touch any of the parts by hand at the
discharge gas side, since the compressor chamber
and the pipes at the dis- charge side are heated
higher than 90°C.

• DO NOT PUSH THE BUTTON OF THE
MAGNETIC SWITCH(ES), it will cause a serious
accident.

• Do not touch any electrical components for
more than three minutes after turning OFF the main
switch

• Confi rm that the gas line stop valve and the
liquid line stop valve are fully open.

• Confi rm that the leakage of the refrigerant does
not exist. The fl are nuts are sometimes loosened by
vibration during trans- portation.

• Check that the refrigerant piping and the
electrical wiring con- form to the same system.

• Confi rm that the dip switch setting on the
printed circuit board of the indoor units and the
outdoor units are correct.

• Check whether or not the electrical wiring of
the indoor units and the outdoor units are connected
as shown in the chapter Electrical Wiring.

A U T I O N

C

Confi rm that fi eld-supplied electrical components

(main switch fuse, fuse-free breaker, earth leakage
breakers, wires, conduit connectors and wire
terminals) have been properly selected ac- cording
to the electrical data given in the Technical Catalog of
the unit and ensure that the components comply with
national and local codes.

N O T E

• For more reference check Troubleshooting
chapter on Opera- tion Part.

• For twin, triple and quad check the indoor unit
outlet air tem- perature at test run. If the temperature
difference is large (aprox. 10 deg. or more (cooling)
20 deg. or more (heating) recheck the refrigerant
piping, Installation may have some problem.

• In the case of anual cooling optional function,
cut JP1 out and set the DSW6-1 to OFF. (Individual
control is not available when anual cooling is
selected).
