1.6 Emergency Measures

Figure 1-16 Location of Emergency Off [EMO] Switch

1.6.1 Emergency off [EMO] switch

Press the red emergency off [EMO] switch on the front of the system only if the
need to shut off the power arises due to emergency such as natural disaster, fire,
earthquake or personal injury.

The emergency off [EMO] switch is a large, red mushroom-shaped push button
labeled with ‘EMO’ on it. The system comes to a halt if this button is pressed.

When press the emergency off [EMO] switch, the control power for this system is
shut off to bring the system to a stop. The main breaker of this system, however, is
designed not to trip, which enables the motor circuit to remain partially energized.

the circuit diagram and see how the EMO switch is interconnected to the system.

Restart of this system is enabled only when this button is reset manually.

No automatic recovery is applied to the emergency off [EMO] switch.
Always eliminate the cause of activating the EMO before resetting.
Potential serious accidents may occur if disregarded.

When the system is in remote mode, the remote mode is retained despite the
power outage. Thus the system operation is to resume as the start signal is
issued from your system.

Chapter 1 Safety

 Reset of emergency off [EMO] switch

1. Before restarting, always make sure that the cause of the emergency off condition (The

reason why the EMO switch was activated) has been eliminated from the power supplies,
the system and peripheral equipment.

2. With the cause completely eliminated,

turn the emergency off [EMO] switch
clockwise to reset.

The EMO button returns to its original position.

3. The screen then changes from the “Model Indication screen” to “Status screen 1” as power

is being restored to the system.

When transporting the system with the casters, raise the adjustable feet
(4 pcs.) to the highest position and lock them with the nuts.
The adjustable foot at the lower position may cause damage to this
system and personal injury through contact with the floor or steps
during system transport.

Proper procedure must be followed when using this system.
Exercise caution to assure personnel safety during the installation, operation,
maintenance, and inspection of the system.

Only personnel, who have adequate knowledge and experiences with not only
this system but associated equipment are allowed to perform transport,
installation, and maintenance involving potential hazardous task.

For transporting with the forklift, be sure to insert the fork into a
designated position, referring to “3.1.1 Transporting with forklift” on
page 3-2.

Do not set this system on its side during transportation. Oil in the
compressor drains into the refrigerant pipe, which causes lubricant
shortages leading to damage to the compressor.

Drain the remaining fluid out of the pipe as much as possible.
The remaining fluid may spill if disregarded.

Exercise caution not to damage the panel and piping with the forklift
when transporting the system.

 This system is heavy, and requires a forklift to safely move it.
 Forklift insertion positions are on either left or right side of this system.

Always insert the forks all the way through. Becareful not to hit the
casters and adjustable feet.

 Do not set this system on its side for transportation. Potential damage to

this system carrying danger of personnel injury if disregarded.

 Do not insert the fork from the back as well as front.

3.1.2 Transporting with caster

This system is heavy, which requires assistance for this work.
Exercise caution and look out for sloped surfaces such as ramps, etc.

Do not grab piping on the back of this system or panel handles when
transporting with the casters.
Potential damage to piping and panels may occur if disregarded.

System installation should be kept from areas with the potential of
flammable gas leak. Ignition may occur if leaked gas is collected
around the system.

This system is NOT designed for outside use.
Potential electric shock, fire and system damage may occur if exposed
to rain, water and dust.

This system is to be installed on a level floor that can withstand the
weight of this system. Potential water leak and personal injury due to
system tipping over may occur if disregarded.

3.2.1 Installation conditions

System installation is not allowed outside or in the conditions described below.
Potential system malfunction and damage may occur if disregarded.

Clean room specifications are not applied to this unit. The pump and ventilating
fan installed in this unit generate particles.

Location that is exposed to water vapor, salt water, and oil



Location that is exposed to dust and powder



Location that is exposed to corrosive gas, solvent, and flammable gas



Location that is exposed to direct sun light or radiant heat



Location where ambient temperature is out of the following range:



In operation 10 to 35°C
In storage 0 to 50°C (with no water or circulating fluid in piping)

Location where relative humidity is out of the following range:



In operation 30 to 70%
In storage 15 to 85%

Location that is subjected to abrupt changes in temperature



Location that is subjected to intense electromagnetic noise (intense electric field,



intense magnetic field, or surges)

Location that is subjected to static electricity, or condition that discharges static



electricity to the system

Location that is subjected to strong high frequencies



Location that is subjected to potential lightning damage



Location with altitudes of 1000m or higher



Location that is affected by strong vibrations or impacts

3.2.2 Installation location and maintenance work area

This system does not have ventilating hole on the both right and left sides. Although this can be
installed directly contacting to walls or devices, installation with maintenance space is
recommended. (See “Figure 3-2)

HRX-OM-I051

To save space, this system can be installed to allow access only in front and back for daily operation
and inspection. For maintenance and repair work, additional access space is required for the left and
right side of the system. We recommend a separate repair area, without taking space from
installation site, to accommodate the needed extra space.

 Anti-seismic bracket is an optional part (except for HRZ008-L, HRZ008-L1), which is

required for the installation of this system (HRZ-TK002).

 Preparation of anchor bolts suitable for floor material is your responsibility. M8-anchor

bolts (8 pcs.) are required for HRZ008-L and HRZ008-L1, and M12-anchor bolts (4 pcs.)
for other models. See “Appendix 8.5 BAND/READY function”
