9 Operation Details
9.1. BASIC FUNCTION
Inverter control, which equipped with a microcomputer in determining the most suitable operating mode as tim
automatically adjusts output power for maximum comfort always. In order to achieve the suitable operatin
microcomputer maintains the set temperature by measuring the temperature of the environment and performi
shifting. The compressor at outdoor unit is operating following the frequency instructed by the microcompute
judging the condition according to internal setting temperature and intake air temperature.
9.1.1.
Internal Setting Temperature
Once the operation starts, remote control setting temperature will be taken as base value for t
These shifting processes are depending on the air conditioner settings and the operation en
will be used as internal setting temperature and it is updated continuously whenever the e

d. R410A refrigerating machine oil
Conventionally, mineral oil or a synthetic oil such as alkylbenzene has been used for R22 refrigerating machine oil. Because
of the poor compatibility between R410A and conventional oils like mineral oil, however, there is a tendency for
refrigerating machine oil to collect in the refrigerating cycle. For this reason, polyester and other synthetic oils which
a high compatibility with R410A are used as refrigerating machine oil.
Because of the high hygroscopic property of synthetic oil, more care must be taken in its handling than was ne
conventional refrigerating machine oils. Also, these synthetic oils will degrade if mixed with mineral oil o
causing clogging in capillary tubes or compressor malfunction. Do not mix them under any circumstance

12.2.2. R410A Tools
1. Copper tube gauge for clearance adjustment
(used when flaring with the conventional flaring tool (clutch
type))
•
This gauge makes it easy to set the clearance for the
copper tube to 1.0-1.5 mm from the clamp bar of the
flaring tool.
Fig. 1 Copper tube gauge f
2. Flaring tool (clutch type)
•
In the R410A flaring tool, the receiving hole for the
clamp bar is enlarged so the clearance from the clamp
bar can be set to 0-0.5 mm, and the spring inside the
tool is strengthened to increase the strength of the pipe-
expanding torque. This flaring tools can also be used
with R22 piping, so we recommend that you select it if
you are buying a new flaring tool.

5. Charging hose
•
The pressure resistance of the charging hose has been
raised to match the higher pressure of R410A. The hose
material has also been changed to suit HFC use, and
the size of the fitting has been changed to match the
manifold ports.

6. Vacuum pump adaptor
•
When using a vacuum pump for R410A, it is necessary
to install an electromagnetic valve to prevent the
vacuum pump oil from flowing back into the chargi
hose. The vacuum pump adaptor is installed for
purpose. If the vacuum pump oil (mineral oil) b
mixed with R410A, it will damage the unit.

CS-TE9DKE CU-TE9DKE / CS-TE12DKE CU-TE12DKE
8. Electronic scale for refrigerant charging
•
Because of the high pressure and fast vaporizing speed
of R410A, the refrigerant cannot be held in a liquid
phase inside the charging cylinder when charging is
done using the charging cylinder method, causing
bubbles to form in the measurement scale glass and
making it difficult to see the reading. (Naturally, the
conventional R22 charging cylinder cannot be used
because of the differences in the pressure resistance,
scale gradation, connecting port size, etc.)
•
•
The electronic scale has been strengthened by using a
structure in which the weight detector for the refrigerant
cylinder is held by four supports. It is also equipped with
two connection ports, one for R22 (7/16 UNF, 20
threads) and one for R410A (1/2 UNF, 20 threads), so
it can also be used for conventional refrigerant charging.
Fig. 7 Electro
There are two types of electronic scales, one for 10-kg
cylinders and one for 20-kg cylinders. (The 10-kg
cylinder is recommended.)
Refrigerant charging is done manually by opening and
closing the valve.
