■Brine
Comply with the precautions when using ethyl alcohol.
Not doing so may result in an explosion or fire.
Do not use calcium chloride brines, silicon oil, organic
solvents, or pure water as the brine.
Doing so may result in parts degradation or equipment damage.
Use an ethyl alcohol aqueous solution or an ethylene glycol brine in the water tank. If the
set temperature is 10 °C or higher, tap water can also be used.
●Cautions if an ethyl alcohol aqueous solution is used
There is a risk that ethyl alcohol will catch fire or explode depending on the usage
environment conditions. Caution is also needed, because at concentrations of 60 wt% or
higher, this becomes a Class 4 hazardous material, and its usage quantity and storage
quantity will be regulated under the Japanese Fire Service Act. Comply with the following
precautions when using this material.
Fires or explosions may result from volatile
gas, so use this material at a well-
ventilated location where no heat sources
in the vicinity reach 300 °C or higher.
Do not use this material if there is a risk
that the ambient temperature will approach
the ignition point.

The table above is a guide only, and the freezing temperature values are not guaranteed.
With ethylene glycol brines, the safe use temperature range and freezing temperature will
differ depending on the manufacturer, so check the respective catalog.
At low temperatures, the viscosity of the brine will increase, and the quantity of brine
may decrease. If the quantity of brine decreases, heat may not be exchanged properly
by the coil in the cooling water tank, and performance may not match the description in
the specifications.
●Brine management
Replace the brine periodically to prevent the equipment from rusting and the brine from
decaying.
If water or ethylene glycol brine is used, ensure that the pH of the brine remains neutral to
weakly alkaline (pH 7.0 to pH 8.0). If it becomes acidic, there is a risk that it will corrode
the equipment. The brine will become acidic if used for an extended period, so check the
pH periodically, and ensure that it remains neutral to weakly alkaline.

16
■Preparations
●Injecting the brine
(1) Check that the drain hose is fastened to
the side, and that the drain cap is on the
hose tip.
(2) Slowly add brine until the cooling coil is
immersed below the liquid surface
(approx. 4 L).
If the cooling coil is not immersed below the liquid surface, moisture in the air will
condense on the coil, and then mix with the brine, reducing the brine concentration.
The liquid level will also increase.
Depending on the type of brine, temperature changes may affect the volume of the
brine. During operation, replenish the brine if the liquid level in the water tank
decreases and the cooling coil becomes exposed.
The water tank is not equipped with an overflow function, so be careful that the tank
does not overflow with brine.
To prevent freezer malfunctions, do not use brine with a temperature of 30 °C or higher.
●Installing the cooling line
Mandatory
Be sure to add the brine to the water tank before installing
the cooling line.
When brine is injected into the water tank after the cooling line is
installed, it may fail to circulate unless the air inside the circulating pump
is removed.
Using hoses at hand, connect the OUT nozzle
to the brine supply destination, and the brine
supply destination to the IN nozzle. At this
point, use hose bands at hand to ensure that
the hoses do not come off during operation.
A coupling style has been adopted for the
nozzles. When removing a nozzle, press on
the grey area on the front while pulling out the
nozzle. When attaching a nozzle, pressing on
the grey area while inserting it will make the
process easier.

< Cautions when attaching/removing hoses and nozzles >
If you are connecting or removing a hose from a nozzle when the nozzle is attached
to the connection port, be careful not to apply unnecessary force to the nozzle
connection port. Otherwise, there is a risk that the nozzle connection port will be
damaged.
If the nozzle connection port freezes, it will not be possible to remove the nozzle. If
you remove it forcibly, there is a risk that the nozzle and nozzle connection port will
be damaged. Be sure that any ice is melted before removing the nozzle.
< Multiple brine supply destinations >
If there are multiple brine supply destinations, to ensure as large a brine return quantity
as possible, install branch pipes just after the OUT nozzle and just before the IN nozzle
to create parallel piping. At the same time, install flow rate adjuster valves for each circuit.
If the piping is in series, the quantity of brine circulating may decrease, and the
inherent cooling performance may not be obtained.
< If the brine supply destination is equipped with a fully closed function >
If the brine supplied equipment uses a solenoid valve to fully close the pipes in order to
conserve fluid or as a safety function, then install a bypass pipe so that the return flow
does not reach zero even when the valve is fully closed.

●Connecting the power supply
Check that the POWER switch is OFF and that
the circuit breaker is OFF ( ). Then connect
the power plug to a 100 V AC grounded 3-pin
power outlet.
If there is no grounded 3-pin power outlet, use
the outlet adaptor provided to connect to a 2-
pin power outlet. In this case, be sure to
connect the ground wire to a ground terminal.
Use an independent power outlet that has a rated voltage range of 100 V AC ±10 % and a
current of at least 15 A. If other equipment is used simultaneously and the power voltage
drops, the freezer may fail to start up properly, resulting in malfunctions.
■Operation
●Temperature setting
(1) Turn ON the circuit breaker ( ), and
turn ON the POWER switch.
The POWER switch will light, and brine

water tank using the drain hose, place the cap on the hose, and fasten it to the side of the
main unit.
●If the brine is not circulating
When brine is injected into the water tank after the cooling line is installed, it may fail to
circulate unless the air inside the circulating pump is removed.
At this point, release the air inside the circulating pump as per the following procedures.
(1) Turn OFF the POWER switch, and
remove all the brine from the water tank.
(Place the brine in a container, and do
not discard it.)
(2) Remove the IN nozzle and the OUT
nozzle.
At this point, be careful as brine may fly
out of the nozzle tip.
(3) Slowly add brine removed in (1) to the water tank until the cooling coil is immersed
below the liquid surface.
The priming liquid will fill the inside of the circulating pump, and the trapped air will be
released.
