Installation
Install properly and DO NOT use this product outside the recommended
operating pressure, temperature and other specification ranges.
Improper use may result in such hazards as damage to the product or
malfunctions which may lead to serious accidents. Local regulations
may restrict the use of this product to below the conditions quoted.
CAUTION
Use hoisting equipment for heavy objects (weighing approximately
20 kg (44 lb) or more). Failure to do so may result in back strain or other
injury if the object should fall.
CAUTION
Take measures to prevent people from coming into direct contact with
product outlets. Failure to do so may result in burns or other injury from
the discharge of fluids.
CAUTION
Installation, inspection, maintenance, repairs, disassembly and adjustment and
valve opening/closing should be carried out only by trained maintenance personnel.
Check to make sure that the piping where the product is to be installed is constructed
properly. If the piping is not correctly constructed, the valve may not perform optimally.
1. Blowdown
Before installing the CV-COS unit, be sure to blow down all piping thoroughly.
If this is not possible, perform a blowdown using the bypass valve. Blowdown is
especially important for newly installed piping or after the system
has been shut down for a long period of time.
2. Removing any Protective Caps and Seals
Before installation, be sure to remove all protective seals and caps.

3. Installation Angle
Install the CV-COS so that the arrow mark on the body
points horizontally in the direction of steam flow, and it
should be installed horizontally in the piping with the
actuator at the top. Allowable inclination is 10 degrees in
the fore-aft direction and 15 degrees in the plane
perpendicular to the steam flow line.
4. Piping Support
Install the CV-COS, paying attention to avoid excessive
load, bending and vibration. Support the inlet and outlet
pipes securely.
