Installation
Proper operation of the FP 400-Torrent Deluge Valves depends upon their trim being installed in accordance with the appropriate
trim configuration guidelines.
Notes
:
■
Any deviation in trim size or arrangement may adversely affect the proper operation of the deluge valve.
■
All the pilot system devices, must be UL-Listed, FM Approved and compatible with the particular system. Refer to current “Fire
Protection Equipment Directory”.
Warning
: The deluge valve and trim must be installed only in areas where they will not be subject to freezing temperatures.
2.1
Installation Instructions
2.1.1
Allow enough room around the valve assembly for any adjustments and future maintenance.
2.1.2
Before the valve is installed, flush the pipeline to remove any dirt, scale, debris, etc.
Warning: not flushing the line may result in the valve being rendered inoperable.
2.1.3
Install the valve on the pipeline so that the valve flow arrow designated on the body casing points in the desired
direction. Ensure that the valve is positioned so that the cover can be easily removed for future maintenance.
2.1.4
Install a Listed indicating valve upstream of the Dry Pipe valve (supervised “open”).
2.1.5
Install another Listed Indicating Valve downstream of the Dry Pipe Valve (supervised “open”) to shut off and
isolate the sprinkler piping in order to allow water flow testing and maintenance.
2.1.6
Install a Drain Valve of appropriate size downstream of the Dry Pipe Valve (normally closed), this drain valve
shall be installed between the Dry Pipe valve and the downstream Indicating Valve for flow test and accumulated
water drain.
2.1.7
The water supply priming line must be connected to the upstream of the main isolating valve.
2.1.8
Subject to all other instructions, drawings and technical specifications, which describe Bermad Valve, install in
their proper positions the components comprising the Water Control Trim Package, according to the drawing
relevant to the specific type, hereby enclosed.
2.1.9
Install the necessary accessories, which appear in the drawing.
2.1.10
All additional accessories, although not packed together with the BERMAD Dry Pipe valve, must be installed as
shown in the relevant drawing and other illustrations.
2.1.11
Install additional accessories that are required by the NFPA codes or by authorities having jurisdiction.
2.1.12
The water supply priming line must be connected to the upstream of the Dry Pipe valve.
2.1.13
After installation in the main line, carefully inspect/correct any damaged accessories, piping, tubing, or fittings;
ensure that there are no leaks.
