Precautions in handling
8. When you need circulation:
•
Detach flexibility pipe or fitting for
the short-circuit and install the
attached hose joint when you
need to circulation at a distance.
Connect a hose with the hose
joint and secure them with hose
clamps not to leak water. When
using silicon oil, select a hose to
resist silicon oil (e.g. fluorine
rubber).
9. When you use liquid, you should
•
The liquid poured into the examination
tank must use water or the silicon oil.
•
It evaporates for water and alcohol, etc.
while using .Replenish sometimes.
•
Using well water or bad-quality water
will cause accumulation of scale and
copestone on the heater pump, etc. Be
sure to use distilled water or pure water
to prevent performance deterioration or
malfunction.
•
The viscosity must use the one to
50CST at 80
℃ or more about the
silicon oil.
