3. Specications

Liquids used

A hydraulic mineral oil viscosity 20 ... 37 cSt at 40 °C viscosity grade VG20 to VG37

to ISO 3448 (BS 4231) is used for the CPB3800 base unit. Most users will be able to

obtain locally suitable oil (see below) as used in hydraulic machinery. However, for the

convenience of users we can supply a 500 ml bottle of oil, viscosity grade VG22.

Other liquids

The pressure balance model CPB3800 is manufactured for use on mineral oil only. If

an end user wishes to use it on another uid, it is the end user responsibility to ensure

that the uid is compatible with high tensile brass, stainless steel, mild steel, and nitrile

rubber, which are the materials that will come into contact with the uid.

Fluids, which attack ABS, should be used with caution. Continual

immersion of the cover in such uids will cause deterioration. Spillages

should be wiped o immediately.

Wear safety goggles!

Protect eyes from ying particles and liquid splashes.
