RASCOFLEX Technical & Installation Instruction
R0029B
CARE AND MAINTENANCE
The users are responsible for the inspection, testing and maintenance of their fire protection systems and devices in
compliance with this document, also in compliance with the applicable standards of the authorities having jurisdiction.
The installing contractor should contact the manufacturer or distributor in the region in relation to any product questions.
It is recommended that automatic sprinkler systems should be inspected, tested and maintained by an approved and
qualified inspection service in accordance with local requirements and/or national codes.
The life expectancy of RASCOFLEX can be determined by various factors including, working conditions and construction
of flexible sprinkler drop, such as operating temperature, operating pressure, bend radius and bending stress beyond its
limitation, the thickness of the corrugation, the corrugation pitch, depth, shape of the corrugation, static condition such
as installation beyond design limitations of flexible drop, and unknown factors of installation performed by contractor.
Any change in one of these factors will void the life length expectations of the flexible sprinkler drop. For longer cycle
life of the flexible sprinkler drop, it is strongly recommended to follow the guidelines of this manual, appropriate Agency
Standards such as LPCB guidelines, FM, VdS and UL as well as local authority’s rules and codes. A manufacturer cannot
predict and dictate every variable which may be encountered during application, installation or any misapplication,
mechanical damage, and/or any uncontrollable situation that may arise during installation.
In case of system malfunction of the flexible sprinkler drop, it is recommended to contact regional distributors for further
information. Distributors and the manufacturer will assist the end user in sourcing the root cause of an issue and to
prevent further malfunctioning of this product. Once the flexible sprinkler drops or any fire protection systems are in
place, the end user should maintain the fire systems through a qualified fire protection maintenance service provider; to
maximize system integrity, to avoid failure and ensure fast and effective response in a fire emergency.
When water additives are added (according to NFPA and International Fire Code, depending on several variables) the
additives need to be between 30 – 70% of the total volume of water in the wet sprinkler system. However, the user of
flexible sprinkler drops must adhere to the industrial installation regulation, such as NFPA as well as local authority rules
and regulations. Failure to do so may cause serious personal injury and property damage. It is recommended to seek
advice for the compatibility of water additives with installation regulators and guidelines, such as NFPA and International
Fire Code.
In addition, depending on the usage and where it is applicable, the user of flexible drops must follow and adhere to the
compliance with appropriate local water regulatory requirements, regulations, rules, or appropriate restrictions on use.
After a fire protection system is in place for service, the user must inform the appropriate authorities and those
responsible for monitoring and maintaining proprietary and/or central station alarms.
Before closing a fire protection system control valve for inspection or system maintenance, the user must obtain
permission from the appropriate authorities and notify all personnel that may be affected.
NOTICE
It is the responsibility of the system designer to verify suitability of RASCOFLEX
stainless steel flexible drop for use with the intended fluid media. The effect of
chemical composition and exposure, pH level, operating temperature, chloride level,
oxygen level, UV light and flow rate on stainless steel flexible drop must be evaluated
by the material specifier; to confirm that the system life will be acceptable for the
intended service and usage. The flexible drop is intended for use indoors.
