TIPS ON ENERGY EFFICIENT VRF DESIGN
TIP No 1:
Shorter pipe run will
minimize capacity loss
and reduce refrigerant
charge in system.
TIP No 2:
Take advantage
of diversity factor
will reduce your
initial capital as
well as ongoing
running cost.
TIP No 3:
Each zone served
by dedicated
unit will help to
increase comfort
level and reduce
Energy waste.
TIPS ON ENERGY EFFICIENT VRF DESIGN
TIP No 4:
Heat recovery system will
not only provide simultaneous
cooling and heating, but also
recover energy that would
be lost in traditional system.
TIP No 5:
Having minimum
Change Over box in same
zone will prevent units
from fighting against each
others and save energy.
TIP No 6:
Unbalanced selection
will cause small unit
starve from Refrigerant
and run longer than
it should be.

2. The sound pressure level is based on following conditions.
1.5 Meter Beneath the Unit.
With Discharge Duct (2.0m) and Return Duct (1.0m).
Voltage of the power source for the indoor fan motor is 220V.
In case of the power source of 240V, the sound pressure level increases by about 1 dB.
The above data was measured in an anechoic chamber so that reflected sound should be taken into consideration in the field.
3. The data for external pressure *3) indicates "Standard Pressure Setting (High Pressure Setting - Low Pressure Setting)"
values when a filter is not used.
The sound pressure level is based on the Standard Pressure Setting.

(*1) The refrigerant piping size may be required to change depending on the outdoor unit to be connected.
If 12.7 pipe is used at the gas side, remove the flare adaptor at the indoor unit gas piping.
Then attach the flare nut (accessory) for pipe connection.

NOTES:
*1): KPI-10021 has different units according to the applied power supply, 220-240V/50Hz and 220V/60Hz.
*2): The sound pressure level is based on following conditions.
1.5 meters beneath the unit and this data was measured in an anechoic chamber so that reflected sound should be taken
into consideration in the field.
*3): The noise at the air outlets is the values at a 45o angle, 1.5 meters in front of the unit.
*4): The sound pressure level is based on the total heat exchange mode.
In case of the bypass ventilation mode, the sound pressure level increase by approximately 1 dB(A).

MISCELLANEOUS NOTES
11. Miscellaneous Notes
Special Notes
1. Provide a service access door near the unit
piping connection part on the false ceiling for the
cassette type units.
2. Consider the air distribution from the unit to the
space of the room, and select a suitable location
so that uniform air temperature in the room can
be obtained.
Cassette and Ceiling Types - Avoid unit
installation in a room where the ceiling height
(distance between the floor to the false ceiling)
exceeds three meters. If the indoor unit is
installed in a room with a ceiling of higher than 3
meters, it is recommended that an air circulation
fan be installed separately to obtain uniform air
temperature in the room, especially during the
heating operation.
3. Check to ensure that the ceiling slab is strong
enough and that the false ceiling is flat and level.
4. Avoid obstacles which may restrict the air intake
or the discharge flow.
5. Do not install the unit in a machinery shop or
kitchen where vapor from oil or its mist can enter
to the unit.
The oil will deposit on the heat exchanger,
thereby reducing the unit performance, and may
deform, in the worst case, break the plastic parts
of the unit.
6. Pay attention to the following points when the
unit is installed in a hospital or other facilities
where electromagnetic wave is radiated from
medical equipment.
(A) Do not install the unit where the
electromagnetic wave is directly radiated to
the electrical box, remote control cable or
remote control switch.
(B) Install the unit and component as far as
practical (at least three meters) from the
electromagnetic wave radiator.
(C) Prepare a steel box and install the remote
control switch in it. Prepare a steel conduit
pipe and wire the remote control cable in it.
And then, connect earth wire with the box
and the pipe.
(D) Install a noise filter when the power supply
emits harmful noise.
7. Do not install the units in an acid or alkaline
environment due to the corrosive action on the
heat exchanger. In the case that outdoor units
are installed near the sea, it is recommended
that optional corrosion-resistant type outdoor
unit be used.
8. Do not install the units in a flammable
environment due to the danger of an explosion.
9. Regarding cassette type indoor units, consider
the direct and reflected sound level, when
selecting the unit for spaces where extremely
low sound is required.
10. During heating operation, the outdoor heat
exchanger produces condensate dew or
melting water from frost.
Install the outdoor unit where drainage of
such water is convenient, or provide a drain
passage.
11. Heating Performance: The heating capacity
normally decreases when outdoor temperatures
decrease. Therefore, provide an auxiliary
heating unit if outdoor temperatures are very
low.
12. In the case that an outdoor temperature is
low and humidity is high, the outdoor heat
exchanger will covered with frost, resulting in
lower heating capacity. In order to remove
the frost, the unit is automatically changed to
the defrosting mode. During this defrosting
operation, the unit is stopped for approximately
3 to 10 minutes.
13. As this unit is of heat pump type by circulating
hot air in the whole room space, it takes time to
heat up the room temperature.
14. The operating sound data is based on an
anechoic chamber. Therefore, the actual
operating sound will be higher due to reflected
sound from the floor and wall.
15. In the case that the unit is operated for a long
time higher than the indoor temperature of
27oCDB or the humidity of 80%, dewing may
occur on the cabinets resulting in dew drops. If
dewing, it is required to add thermal insulator
on the cabinets.
16. Provide snow-protection hoods to prevent the
outdoor heat exchanger from snow clogging.
If the unit is operated in an are where it snows
heavily, provide a base under the outdoor
unit which should be 50cm higher than the
presumable maximum snow height.
17. It is recommended that periodical service and
maintenance be performed by authorized
service engineers before air conditioning
seasons, in order to avoid performance
decrease due to dust or dirt.
18. This heat pump air conditioner has been
designed for normal air conditioning for men.
Do not apply to other purposes such as for
food, animals, plants, high precision machines
or work of art. Also do not apply to vehicles
or vessels. It will results in water leakage or
electrical leakage.
19. It is recommended that the system be installed
by authorized engineers. If not, it may cause
water leakage, electric shock or fire.
20. In a place where fibers or dusts are floating, the
air filter or heat exchangers or the drain pipe
may be clogged, resulting in water leakage
from the drain pan.

* In case of material 1/2H, flaring is not available.
* In case of material 1/2H, bending is not available.
Use elbow for bend and braze.
* In case of material 1/2H, expanding of tube is not

* For 12.7, 15.88, spanner size is up 2mm.
* For 6.35, 9.53, 19.05, spanner size is the same.
* Perform correct brazing work.

* Synthetic oil absorbs moisture quickly.
* Check refrigerant cylinder color.
Refrigerant Charging
Liquid refrigerant charging is required regarding
zeotoropic refrigerant.
Vacuum Pumping
The current ones are applicable. However, it is
required to mount a vacuum pump adapter which
can prevent from reverse flow when a vacuum pump
stops, resulting in no reverse oil flow.
