accessible to the general public”.
• Follow the showcase to be connected for the climate class.
(EN60335-2-89)
[EMC CHARACTERISTICS]
This System is a class A product. In a domestic environment this
product may cause radio interference in which case the user may be
required to take adequate measures.
[REFRIGERANT]
This System use R410A refrigerant.
CAUTION
This unit is already filled with a certain amount of R410A.
Never open liquid and gas shutoff valve until the step Specified in “9.
CHECKS AFTER WORK COMPLETION”.
• The refrigerant R410A requires strict cautions for keeping the system clean, dry and tight.
Read the chapter “REFRIGERANT PIPING” carefully and follow
these procedures correctly.
A. Clean and dry
Foreign materials (including mineral oils such as SUNISO oil or
moisture) should be prevented from getting mixed into the system.
B. Tight
Take care to keep the system tight when installing.
R410A does not contain any chlorine, does not destroy the
ozone layer, and does not reduce the earth’s protection
against harmful ultraviolet radiation.
R410A can contribute slightly to the greenhouse effect if it is
released.
• Since R410A is a mixed refrigerant, the required additional refrigerant must be charged in its liquid state. If the refrigerant is
charged in a state of gas, its composition changes and the system
will not work properly.
• Be sure to perform refrigerant replenishment. Refer to
“9. CHECKS AFTER WORK COMPLETION” and the label of
instructions on refrigerant replenishment on the cover surface of
the control box,

• Route the path to the indoor unit heat exchanger so that the flow
of refrigerant is from top to bottom.
• When installing a number of indoor units, be sure to install them at
the same level.
• Use either off-cycle defrosting or electric heater defrosting as the
defrosting type. Hot-gas defrosting models cannot be used.
3. SELECTION OF LOCATION
Select a location for installation that meets the following conditions.
Get the customer’s permission.
1. There is no danger of fire due to leakage of inflammable gas.
2. Select the location of the unit in such a way that neither the dis-
charged air nor the sound generated by the unit disturb anyone.
3. The foundation is strong enough to support the weight of the unit
and the floor is flat to prevent vibration and noise generation.
4. The piping length between the outdoor unit and the indoor unit
may not exceed the allowable piping length. (Refer to
“6. REFRIGERANT PIPING”)
5. Locations where the unit’s suction vent and outlet vent do not gen-
erally face the wind.
Wind blowing directly into the suction or outlet vents will interfere
with the unit’s operation.
If necessary, install some kind of obstruction to block the wind.
6. The space around the unit is adequate for servicing and the min-
imum space for air inlet and air outlet is available.
(See the “Installation Space Examples” for the minimum space
requirements.)

6. REFRIGERANT PIPING
To Piping Work Contractors
• Never open the shutoff valve until the steps specified in “7. FIELD
WIRING” and “8-3 Checking of Device and Installation Conditions” of piping.
• Do not use flux at the time of brazing and connecting refrigerant
pipes. Use phosphorous copper brazing filler metal (BCuP-2),
which does not require flux. Chlorine-based flux causes piping
corrosion. Furthermore, if fluoride is contained, the flux will have
adverse influences on the refrigerant piping line, such as the dete-
20
rioration of refrigerating machine oil.
CAUTION
• All field piping must be installed by a licensed refrigeration technician and must comply with relevant local and national regulations.
[Precautions for reuse of existing refrigerant piping / heat
exchangers]
Keep the following points in mind for the reuse of existing refrigerant piping / heat exchangers.
A malfunction may result if there is deficiency.
• Do not use the existing piping in the following cases. Perform new
piping instead.
• The piping is different in size.
• The strength of the piping is insufficient.
• The compressor of the CONVENI-PACK previously used
caused a malfunction.
An adverse influence of residual substances, such as the oxidation of refrigerant oil and the generation of scale, is considered.
• If the indoor unit or outdoor unit is disconnected from the piping
for a long time.
The intrusion of water and dust into the piping is considered.
• The copper pipe is corroded.
• The refrigerant of the CONVENI-PACK previously used was
other than R410A (e.g., R404A / R507 or R407C).
The contamination of the refrigerant with heterogeneity is considered.
• If there are welded connections midway on the local piping, make
gas leakage checks on the welded connections.
• Be sure to insulate the connection piping.
The liquid and gas pipe temperatures are as follows:
Liquid pipe arrival minimum temperature
20°C (Air-conditioning side)
5°C (Refrigeration side)
Gas pipe arrival minimum temperature:
0°C (Air-conditioning side)
–20°C (Refrigeration side)
In the case of thickness insufficiency, add additional insulation
material or renew the existing insulation material.
• Renew the insulation material if the insulation material is
degraded.
Keep the following points in mind for the reuse of existing heat
exchangers
• Units with insufficient design pressure (since this product is an
R410A unit) require a lower-stage design pressure of 2.5 MPa
[25 bars].
• Units for which the path to the heat exchanger has been routed so
that the flow of refrigerant is from bottom to top.
• Units with copper tubing or fan corrosion.
• Units that may be contaminated with foreign matter such as rubbish or other dirt.
