∗1 This is a manual fluid fill port that is
different from the automatic fluid fill
port. Fluid can be supplied manually
into the tank without removing the
side panel. (Fluid can be supplied
manually for models without option K
if the side panel is removed.)

∗1 When the ambient temperature or circulating fluid
temperature is 10°C or below, refer to "Operation at
low ambient temperature or low circulating fluid tem-
perature" (page 15).
∗2 Use fluid in condition below as the circulating fluid.
Tap water: Standard of The Japan Refrigeration And
Air Conditioning Industry Association (JRA GL-02-
1994)
15% ethylene glycol aqueous solution: Diluted with
clean water, without any additives such as antisep-
tics.
Deionized water: Electric conductivity 1 μS/cm or
higher (Electric resistivity 1 MΩ·cm or lower)

∗6 Fluid flow rate to maintain the cooling capacity. If the
actual flow rate is lower than this, install a bypass
piping.
∗7 If the product is used at an altitude of 1000 m or
higher, refer to “Operating Environment/Storage Envi-
ronment” (page 14) Item 13 “For altitudes of 1000 m
or higher.”
∗8 The anchor bolt fixing brackets (including 6 M8 bolts)
are used for fixing to wooden skids when packaging
the thermo-chiller. No anchor bolt is included.
∗9 For the product operation in the UL compliant condi-
tions, refer to “Operating Environment/Storage Envi-
ronment” (page 14).
