Installation
Section 3: Installation
Pre-Installation Considerations
At delivery each component is separately packed for water and dust protection so any
precaution must be kept to reduce the risk of getting dust, water and foreign matters
entering the components.
All Bettis equipments have been flushed to NAS 1638/10 and plugged and function tested
before leaving Bettis.
Equipments ready for use, such as power units, control cabinets, actuators etc. do not
require flushing prior to putting into service.
3.1
Storage and Transport
3.1.1
Storage before Installation
The system equipment must be stored under shelter in their original shipping boxes with
protection for rain, preferable in dry indoor place, not directly exposed to wind, rain, sand,
dirt, etc. The equipments with packing should be kept from the possibility of physical
damage and protected against environmental dust. Moist conditions should be avoided.
The equipments should be stored in an easily accessible place where they can be easily
brought out for rigging work.
3.1.2
Transport and Storage
Use proper lifting facilities and transportation equipment.
In case of lifting, take care not to damage the painting. Scratches or damage of a coated
area can cause galvanic corrosion. If scratched repair before equipment is finally installed.
The valves shall be storage and transported in a way to avoid damage on the valve rubber;
e.g. an actuator on valve must not make full contact with the rubber ring on another valve.
By transport, storage and dispatch of actuators type FO, the disc (which in this case is open)
must be protected and packed so damage on the disc will be avoided.
3.1.3
Dispatch
All valves shall be 2 – 5 mm open at dispatch to avoid that the disc is sticking in the rubber.
However, this does not apply to spring closed valves.
CAUTION
Transit and shipment of actuators type FO (Fail Open) must always be done without
hydraulic pressure. This means that the valve in this case is open. Have your attention on
this when handling FO actuators.
