 Choose proper external piping with consideration for pressure,

temperature and compatibility with the circulating fluid. Potential pipe
rupture during operation may occur if disregarded.

 Always insulate external circulating piping. Potential insufficient cooling

performance due to heat absorption from the pipe surface and potential
insufficient heating performance caused by thermal radiation if
disregarded.

 Use clean pipes and pipe fittings, free of particles, oil and moisture.

Apply air blow to the parts before using. The presence of particles, oil or
moisture in the circulating fluid circuit causes system failure attributed to
insufficient cooling or froths in the circulating fluid in the tank.

 Install circulating fluid piping not to exceed 10m high. The maximum

amount of circulating fluid in piping, including your system, should
remain under 2.5L if 7m or higher circulating fluid piping is installed (for
HRW-H, -HS). An alarm may be raised, or potential fluid leak from the
tank may occur at system stop if disregarded.

 Be sure to choose a circulating fluid pipe capable of letting the fluid flow

at rated flow rate or better. See “Pump performance” defined in

“Appendix 8.1.1 System specification” for the flow rate rating.

 Have a drip pan available incase of a fluid leak.
 Make sure of the locations of ports for the circulating fluid supply, return,

facility water inlet, outlet and their corresponding connections are
correct.

 Install valves in circulating fluid piping for flow rate adjustment and

maintenance. As the value of flow rate displayed on the screen will be
less than proper value when flow rate is excessive, flow rate adjustment
should be started with the valves shut. See “Circulating fluid flow rate
display range” defined in “Appendix 8.1.1 System specification” for the
flow rate display range.

 Secure the piping connector section with a pipe wrench, and provide

proper tightening to the pipe.

 Avoid physical shock when securing and tightening the connectors.

Potential breakage and fluid leak may occur if disregarded.

Rear

Circulating fluids to use vary with system models.
See section 8.1.1 “System specification” in Chapter 8 for the
designated circulating fluid for a specific model.

 High concentration EG in the circulating fluid may cause circulating pump overload,

which triggers “Pump Breaker Trip FLT”.

 Potential cooling error may occur if the circulating fluid varies in concentration.

Make sure of no oil, moisture, and other foreign materials contaminate the
circulating fluid. Potential cooling error or system failure, due to contaminant
freezes internally, may occur if disregarded.

Attention should be taken on water quality. Ensure water quality is within specified
range, and other foreign materials contaminate the circulating fluid. Potential
cooling error or system failure, due to contaminant freezes internally, may occur if
disregarded.

4.3 Supply of Circulating Fluid HRW Series

4-3

4.3.2 Supply of circulating fluid

When supplying the circulating fluid, make sure that the fluid inside
this system has dropped to room temperature for the prevention of
burns.

Circulating fluid must be supplied to be in the range between “HIGH”

and “LOW”. Potential overflow of hot circulating fluid may occur due

to excessive volume.
Total fluid volume use to fill up the system including initial priming
should not exceed combined volume of Sub Tank and Main Tank.
If level is below the “LOW” mark, this system will trigger an alarm.

Be sure to tighten the cap until it clicks after circulating fluid supply.
Potential circulating fluid vaporization may occur if disregarded.

Remove the circulating fluid fill cap, and fill the circulating fluid until it reaches its
specified level.
The circulating fluid specified level is a range between “HIGH” and “LOW” in
Figure 4-1.

Be sure to tighten the cap until it clicks after fluid supply.
If the circulating fluid is supplied over the specified level, follow the procedure
provided in section 7.3.1 “Draining of circulating fluid out of tank” on page 7-4 to
drain excess fluid until it reaches the specified level.

[Tips]

Level between “HIGH” and “LOW” represent liquid level in normal running

condition. Immediately as you start filling up the chiller, the internal
transferring pump start pumping fluid from the Sub Tank into the Main Tank.
Thus the fluid level in the level gauge will start to drop.
During initial priming of the external piping, addition fluid is needed. See
section 8.1.1 “System specification” on page 8-1 for Sub Tank and Main Tank
capacity.

8.4 Offset Function

Potential deviations in temperature between this system and your system may be
concerned depending on the installation environment. The offset function falling
into three types (MODE1 to 3) is assigned to calibrate deviations in temperature.
See the following descriptions for the offset function. See section 5.3.9 “Initial
Setting screen” for setting.

TEMP PV value, which is displayed on the Status screen, is output as circulating
fluid temperature data in terms of communication.

When MODE1 is selected



This mode is used to exercise temperature control to allow the discharge
temperature of the circulating fluid to be “TEMP SP value + OFFSET value”.
TEMP PV value denotes the discharge temperature of the circulating fluid.

E.g.: TEMP SP value: +20°C, OFFSET value: +2°C

 Circulating fluid discharge temp.: +22°C, TEMP PV: +22°C

When MODE2 is selected



This mode is used to exercise temperature control to allow the discharge

temperature of the circulating fluid to be “TEMP SP value”.
TEMP PV value denotes “Circulating fluid discharge temp. value + OFFSET
value”.

E.g.: TEMP SP value: +20°C, OFFSET value: +2°C

 Circulating fluid discharge temp.: +20°C, TEMP PV: +22°C

HRX-OM-K003

Chapter 8 Appendix

When MODE3 is selected



This mode is used to exercise temperature control to allow the discharge
temperature of the circulating fluid to be “TEMP SP value + OFFSET value”.

TEMP PV value denotes “Circulating fluid discharge temp. value - OFFSET
value”.

E.g.: TEMP SP value: +20°C, OFFSET value: +2°C

 Circulating fluid discharge temp.: +20°C, TEMP PV: +20°C

When OFF is selected



If no mode is selected, temperature control is conducted to allow the discharge
temperature of the circulating fluid to be “TEMP SP value”.

8.4.1 Example of offset function

When the discharge temperature of the circulating fluid is at 30°C, heat is
dissipated by 1°C to allow the circulating fluid in your system to be 29°C. Under
the above condition, the following process is to be performed with the utilization of
MODEs 1 to 3.

Figure 8-4 Example of Offset Function

 When MODE1 is selected

This mode enables this system to exercise temperature control to obtain 31°C
(TEMP SP value +OFFSET value), with OFFSET value set at 1°C. Once the
discharge temperature of the circulating fluid becomes 31°C, 1°C-thermal
dissipation is assured to allow the circulating fluid in your system to be 30°C.
TEMP SP value is obtained for your system.
Note that “31°C” is recorded in TEMP PV and communication data.
