Precautions For Installation - Yoshitake CF-60 Manual

4. Precautions for installation

 Caution
(1) Before installing the product, remove foreign substances and scale from the piping,
and note that seal materials must not flow into the inside of the product or piping.
Commingling of foreign substances such as scale or seal material leads to
malfunction of the product.
(2) To install the product, check the direction of the product so that the fluid flowing
and the mark on the product are in the same direction.
･For screwed connection, the arrow is shown on the label.
･For wafer connection, "IN/OUT" is shown on the fin.
* Wrong direction leads to malfunction of the product.
(3) Install pipes so that excessive load, torque or
vibration is not applied to the product.
(4) When using this product, running sounds occur. Please
install it as far away as possible from places where low
noise is required.
(5) On installation, align center part of the product with that of
flange by making fin-shaped part contact with bolt as
indicated in the right figure.
*The flange, bolt and nut are not included in the bundled parts.
(6) If component having negative effect on inner parts is included in fluid and
environment, deterioration of rubber parts is accelerated and causes outside
leakage and functional disorder.
(7) Impact by rapid pressure change, such as water hammer, breaks the product or
parts.
(8) If fluid cannot flow due to closed piping situation of the product, fluid temperature
rise expands volume of fluid in the piping and damages the product.
(9) Secure enough space needed for maintenance and inspection of the product.
(10) Do not make dissimilar metal piping which causes difference of electrical potential.
If doing so, the product and parts are corroded.
(11) Consider usage condition (usage frequency or durability) when selection.
(12) Install a strainer (mesh size of 60 or 80) at the inlet side of the product.
* Commingling of foreign substances such as scale material leads to prevent the
product from functioning properly.
(13) The majority of product failures are happened due to scales such as sands and
dust in the pipeline. Please pay attention to the dust inside the pipeline.
(14) The products cannot be used with pipe end core.
