Installation Precautions
Preparation of circulating water
Select circulating water according to the operating temperature.
If objective temperature is 10 °C or higher, use tap water or softened tap water *
If objective temperature is lower than 10 °C, use an antifreeze solution, such as
Nybrine
®
(dilute with tap water)
<Recommended Concentration>
at 5 to 10 °C: Z1 30%
at -20 to 5 °C: Z1 60%
* Do not use pure water as circulating water
The ready-to-use Raku-raku line of Nybrine
®
solutions from Yamato Scientific is
recommended. Contact original dealer of purchase for Raku-raku Nybrine
®
solutions.
Observe the following in order to prevent malfunction
・
Replace circulating water entirely every three months for tap water/ethanol solutions or
every six months for Nybrine
®
solutions. Failure to do so may cause failure in cooling coil
or circulation pump.
・
Do not use liquids with viscosities higher than 300cp as this may cause failure of the
circulation pump.
・
Do not use liquids (caustic soda, sodium hydrate, etc.) that will powder when evaporated.
・
Degraded unit performance and/or pump overload may be caused by using heavy or
viscous circulating water, such as Fluorinert
TM
, Galden
Ⓡ
, etc.
・
Do not use pure water as circulating water. It may corrode the copper in the wetted part.
・
Do not use corrosive liquid or circulating water that generates corrosive substances when
heated (Fluorinert
TM
, etc.). When using a mixture of antiseptic agents, select it according
to the material of wetted part.
Material of wetted part
Reservoir: SS304, cooling coil: Ni
FittingsSS304, C3604
+
Ni, PP, Hoses: Si (milk-white)
Be careful when operating unit in an environment specified below.
・
When using ethanol as antifreeze liquids, be sure to provide adequate ventilation and not
to allow anything that may be a source of fire or ignition (static electricity, etc.)
approached.
・
Do not use circulating water that will be harmful when vapor is breathed in (methyl
alcohol, etc.) .
