Head Placement
•
Between 1.40 and 1.45 m high for sprayhead in non-kitchen area.
•
Between 1.20 and 1.45 m high for sprayhead in kitchen area.
•
In a “preferred position” and clear from obstructions (1.5 m around the head).
•
Head placement matches the layout drawing supplied with the commissioning form.
•
The coverage must be in line with Plumis Guidelines and the guidance in this DIOM. Any deviations
must be justified by the Designer and agreed in written with the AHJ.
High Pressure Hose
•
High pressure hose must have been flushed with air to remove water, avoid dripping and Legionella.
•
High pressure hose must be protected by a fire resisting barrier, and a fire resisting sleeve if exposed.
•
It is critically important that the high-pressure hose locking pin (behind the pump) is in position so that
the quick connector and O-ring are firmly retained after any operations that required disconnection of
the high-pressure line.
•
Appendix C (high pressure hose specification) is met.
Stainless Steel Piping (alternative to high pressure hose)
•
Material: Stainless Steel
•
Stainless steel pipes and fittings must conform to
UK (BS 8458:2015): ASTM A269-10 and ASTM A312
US (NFPA 750): ASTM A269 or ASTM A 632 or ASTM A 778 or ASTM A 789/ A 789M
•
Internal diameter: 5/16” (8 mm)
•
Working pressure at least: 150 bar
•
Maximum total length: 50 m
Fire Stopping
•
Ensure any connections between fire-separating elements are fire-stopped at both ends to maintain
the continuity of resistance.
Coverage
•
IMPORTANT!
It is the designer’s responsibility to ensure when using the product as part of a fire
strategy or for code compliance to ensure the system is installed as per the guidelines (see page 24).
•
If protecting the means of escape only, ensure all adjacent rooms which are not separated by a fire
resisting door are covered. Covering only the stairs will not suppress fires in non-separated adjacent
rooms, negatively impacting tenability on the escape route.
Documentation
•
Installer sign-off details (including pump pressure) are noted on pump.
•
An occupant information sheet must have been provided to the property.
•
The Installer Commissioning form must have been provided (can be obtained from Plumis or the
installer) with a matching layout drawing.
•
The Plumis Warranty Certificate is provided (can be obtained from Plumis) once the layout has been
submitted and approved by Plumis.
•
It may be useful to take photos of any safety critical elements for your own records.
