3.2 Installation

 Keep the product horizontal to a rigid and flat floor which can

resist the weight of the product, and take measures to prevent the
product from tipping over. Improper installation may cause water
leakage, tipping, damage of the product or injure the operator.

 Keep the ambient temperature of the product between 5 to 35oC.

Operation below 5oC may cause the compressor failure, and
operation above 35oC may cause the product to overheat and shut
down.
 Power supply 200V : The operating ambient temperature is 5 to
40oC.

 Do not set up the product in places possibly exposed to leakage of

flammable gas. Should any flammable gas stay around the
product, the product may cause a fire.

 Do not use the product outdoors. If the product subjected to rain

or water splash it may cause electrical shock, fire or failure.

 Only qualified persons are allowed to wire the product.
 Be sure to shut off the user’s power supply. Wiring with the

product energized is strictly prohibitted.

 The wiring must be secured to the product to prevent the external

force of cables being applied to the terminals. Incomplete wiring or
improper securing of wiring may cause electrical shock, excessive
heat and fire.

 Ensure a stable power supply with no voltage surges.
 Ensure that an Earth Leakage Breaker is used in the power supply

of the product. See “Table 3-2”.

 Use a power supply suitable for the specifications of the product.
 Be sure to connect the ground connection.
 Ensure that a lock out facility is availble on the power supply.
 Each product must have its own separate Earth Leakage Breaker.

Otherwise there can be a risk of electric shock or fire.

 Do not modify the intenal electrical wiring of the product. Incorrect

wiring may cause electrical shock or fire. Also, modifing the
internal wiring will void the product’s warranty.

 Connect piping firmly. Incorrect piping might cause leakage of

supplied or drained leakage and wet surrounding area and facility.

 Pay attention not to allow dust and foreign materials to enter into

water circuit etc. during connection of piping.

 Hold the piping port firmly with specific wrench when tightening.
 The piping should be selected with due consideraton of pressure and

temperature. Otherwise, the piping can burst in service.

 Do not use the materials that rust or corrode for the circulating fluid

circuits. Using the materials that tend to rust or corrode may cause
clogs or/and leakages of the circulating fluid circuits. In case of
using these kind of materials, consider and carry out some
prevention against the rusting or corrosion by the customer side.

 Do not generate a rapid change of pressure by water hammer etc.

4.3 Preparation of circulating fluid

When the circulating fluid tank is filled the user’s machine and piping remains
empty. In that condition, the circulating fluid flows out to the user’s machine

and piping and the tank level decreases and may require a refill. In that case,
refill the circulating fluid in the following procedure.

1. Press the [PUMP] key on the operation display panel (press the [RUN/STOP] key and

[MENU] key simultaneously).
The pump operates independently while the [PUMP] key is pressed. The [RUN] lamp

(green) flashes while the pump is operating independently, and the circulating fluid in
the tank is supplied to the customer’s device and piping. This can be done to check for
leakage, and to discharge air from the piping.

When the fluid level in the tank drops below the "L" level, stop the operation of the
pump itself, and add some circulating fluid into the tank. Repeat the same sequence
after adding the fluid until the fluid level in the tank stops decreasing. When the liquid
level in the tank stops decreasing, it means that the circulating fluid is filled completely
in the piping of the user's facility.

4.6 Adjustment of Circulating Fluid

 Flow adjustment

HRX-OM-R039

Chapter 4 Starting the Product

If the flow rate is less than 5L/min it will not be able to achieve the specified
cooling capacity. The adjustment of flow rate should be performed using a
manual bypass valve and monitoring the pressure or flow rate in the

customer’s device, referring to the recommended piping flow shown in

Figure 3.4-2, until they reach the required value.

When the flow rate of the circulating fluid becomes 4L/min. or lower, a



protective device of the thermo chiller operates to stop it's operation.
("AL07" alarm will be generated.)

Please reconsider the piping of the equipment that the product is



connected to, or consider using the "Bypass piping set; HRS-BP001"
that is available as an option.

Use specified circulating fluids only. If other fluids are used, they may
damage the product or result in dangerous hazards.
When using fresh water (tap water) ensure that it satisfies the water
standard shown in the table below.

Clean the tank, circulating fluid circuit, and change the circulating fluid
in the tank if any problems are found during the regular check.
Additionally, even if no problems are found, it is necessary to change
the fluid once every 3 months in case evaporation of the fluid causes
concentration of impurities. Refer to the page containing "7.2

 Removal of the dustproof filter

1. The dustproof filter is installed at the lower part of the front face of the thermo-chiller. It is

mounted with a magnet.
Pull out the lower part of the side surface of the dustproof filter.

2. When the magnet comes off, pull the dustproof filter downwards to remove.
