Features
■ Safety refrigerant system
 Equipment of dual refrigerant circuit (including fan motor) and adoption a new
control method for effectively utilizing it.
(Keeping inside chamber temperature -65℃ at ambient temperature 30 ℃ when
one side compressor failure )
 Usage environmentally friendly of HFC mixed refrigerant
 Filterless cooling circuit without cleaning
 VIP PLUS in front of the housing
■ Control and monitoring system

Stop only abnormal compressor by a manual reset shutoff device at the time of
compressor abnormal equipped for each compressor. Protection the store at normal
refrigeration circuit

Installation centralized monitoring system (MTR-5000) and LAN interface board
(MTR-L03 except for Europa) (Option)

Monitoring the use environment situation and informing appropriate operating
environment by LCD panel (status mode).
■ Visualization safety

Improvement of visibility operation by LCD touch panel controller

Monitoring and display some running conditions

Data management by logging function for monitoring (temperature logging)
■ Environment

Display safety energy operation mode

Compliance with RoHS (Restriction of Hazardous Substances Directive )
Caution
*Parts replacement and option unit installation must be done by trained service engineer.
*Service engineer must refer to the section “Electric parts ” and “ Cooling unit parts”
about the parts for those operation.

2. Collection
1) Collect gas from the system by using collector.
2) To prevent fire, ensure to perform vacuum evacuation
for 5 minutes through compressor, because flammable
R-600 is mixed in the oil.
Note) Ensure to perform vacuum evacuation
before brazing.

3) Connect charging pipe with unit.
If the pipe is short, attach connector with the pipe.

4) Measure tank weight by scale.
Then connect the tank with both gauge manifold and pump.
Pull vacuum 3hours at least through vacuum pump.
Ensure vacuum pump capability should be 300L/minute.

3. Charging gas
1) Turn the pump off 3 hours later.
Open the valve to charge gas in the unit.
Gauge pressure should be 0.2 through 0.5Kg/Mpa.

For the person who performs installation
Backup Cooling Kit Installation Instructions
Follow these instructions when installing the liquid CO2 cylinder of backup cooling kit
for ultra-low temperature freezer.
WARNING
As with any equipment that uses CO2 gas, there is a likelihood of oxygen depletion in the vicinity of the
equipment. It is important that you assess the work site to ensure there is suitable and sufficient
ventilation. If restricted ventilation is suspected, then other methods of ensuring a safe environment must
be considered. These may include atmosphere monitoring and warning devices.
Liquid CO2 cylinder should be installed in the special cylinder stand. The cylinder should not be left
outside of the stand.
PRECAUTIONS
Before installation
●Liquid CO2 cylinder should be a siphon type cylinder.
●Only liquid CO2 can be used for this system. Never use other kind of gases.
●Liquid CO2 loses its cooling capacity when the ambient temperature is above +31℃. Do not install the
liquid CO2 cylinder in a place exposed to direct sunlight or near heat-emitting appliances such as
stoves and heaters. The back-up time per 1 liquid CO2 cylinder depends on the ambient temperature.
Install a liquid CO2 cylinder in the cool location.
● Liquid CO2 cylinder should be installed in a special cylinder stand (see figure).
Never install the cylinder without the stand. If you have difficulty in obtaining the
stand, contact your dealer.
●The length of time in which a 30kg liquid CO2 cylinder can maintain a
temperature of －70℃ is shown in the another sheet “Ambient Temperature vs.
－70℃ Holding Time of Liquid CO2 cylinder (30kg)”.
Install the required number
of cylinders according to the customer’s desired back-up time.
●Before installation, tell the customer about cylinder storage and exchange procedures at the time of
cylinder inspection according to high-pressure gas regulations.
-53-
At installation
● The connecting pipe between the liquid CO 2 cylinder and the
backup cooling kit should not be installed in a place where it may
be bumped in a passage.
● Use the connecting pipe provided with the backup cooling kit.
Run the connecting pipe in a coil or U-bend formation to act as a
cushion (see figure).
● Do not let foreign particles or water get into the pipe or joints.
After installation
● Check that liquid CO2 is injected into the freezer chamber. Refer to the “Injection Test” for an
explanation of the testing procedure.
● Conduct a leakage test of the liquid CO2 cylinder and connecting area.
-54-
Installation
1. Put the liquid CO2 cylinder into the CO2 cylinder stand.
Secure each cylinder to the stand with chains.
Sleeve
Flared nut
2. Connect the valve on the CO2 cylinder stand with the
CO2 outlet of the cylinder with a flexible hose.
3. Close the valve on the CO2 cylinder stand completely
Ring
Pipe
パイプ
Fig.1
and open the cylinder valve. Then check for CO 2 leakage
at the cylinder valve, cylinder stand valve and the
connecting area of the flexible hose.
4. When no leakage is found, close the cylinder valve.
5. Cut the connecting pipe (total length; 2.5m) enclosed
with the backup cooling kit into an appropriate length.
The cut end should be connected to the back-up
system.
Fig.2
6. Remove the cap covering the connecting port on the
backup cooling kit. Place the flared nut, ring, and sleeve
onto the end of the connecting pipe as shown in Fig. 1.
Soapy water
7. Insert the cut side of the connecting pipe all the way
into the connecting port on the backup cooling kit and
tighten the flared nut securely.
8. Connect the other side of the connecting pipe with the
cylinder valve (when 1 cylinder) or the cylinder stand
Fig.3
valve (when more than 1 cylinder). Tighten the flared nut
all the way.
Note:
Run the connecting pipe in a coil or U-bend formation to act as a cushion (see Fig. 2).
9. Open the valve installed the container set stand or the container valve, and make sure that there is no leak
in the both ends of connection pipe. Leakage will find by painting the soapy water to the connecting portion.
（Fig.3）
10. Shut all container valves in this state. And also closed valve installed the container set stand
11. By "injection test” below, please perform the injection test.
-55-
Injection test
1. Run the freezer until the chamber temperature reaches the appropriate level.
2. With the power switch of the backup cooling kit turned off, open the cylinder valve and the cylinder
stand valve.
3. Set the temperature of the backup cooling kit to a temperature 10℃ or more higher than the freezer
chamber temperature.
Note:
The temperature setting range of the backup cooling kit is between － 50 and － 70 ℃ . The
consumption of liquid CO2 gas is increased and the backup cooling time is decreased considerably if
the set temperature is lower than －70℃.
4. Turn on the power switch of the backup cooling kit with the freezer door closed. For the up-right
freezer, check the indicator lamp (green) on the door switch is ON.
5. Press the test switch for the backup cooling kit to check the liquid CO2 gas is injected into the freezer
chamber.
With the back-up system set in this way, the liquid CO 2 gas is injected into the freezer chamber
automatically to ensure freezing when the chamber temperature reaches the set temperature of the
backup cooling kit.
6. If the set temperature of the backup cooling kit is below －60℃, turn off the power switch of the
freezer.
7. Check the liquid CO2 gas is injected into the freezer chamber automatically when the chamber
temperature rises.
8. Ensure the injection of the liquid CO2 gas automatically stops when the chamber temperature goes
down. Note the backup cooling time is decrease if the liquid CO 2 gas is injected continuously.
● Refer to the “Operating instructions” for an explanation of switches on the freezer.
