Special Notes
This pump has been used by many of our customers, but while it is rare for this to happen, this
circulating pump inadvertently stops and as a result requires repair.
The reason for this is described below.
To help prevent this circulating pump from stopping inadvertently and use it with peace of mind,
we recommend that you consider the following items.
(1) Rust forms on the circulating pump from the residual water, which
results from the pump being stopped for a long time.
(2) Foreign objects have built up in the circulator pump from
circulating extremely contaminated oil.
(1) Rust tends to form while the circulating pump is stopped. Therefore, even
after the work task is finished, continue to start up the pump only and
circulate oil.
If the pump must be stopped for a long time, separate the water sufficiently
after the vacuum pump has stopped, and drain it.
Thereafter, replace the vacuum pump oil with new oil, circulate the new oil
(without water) in the pump and then stop the pump.
(2) When the oil becomes extremely contaminated, replace it with new oil right
away.
