2.1.1
INSTALLATION
Ducts, fittings etc. will, when installation is completed, be completely free from; debris, oil (from manufacturing of duct), dust, drill cuttings and all other products that can jeopardize indoor air quality or function of filters, dampers, terminal units etc.
Ducts will when delivered to site be either: by suitable means, manufactory cleaned and sealed or cleaned on site before erection with, by the client, approved means and methods. Depending on manufacturing methods cleaning of ducts could be omitted.
Open ducts and all other openings in the duct system immediately after erection will be covered with dust-tight covers to maintain required cleanliness.
Fittings and equipment that will be installed in the ductwork shall be kept in their dust-tight wrappings until installed.
Fasteners: Rivets, bolts or sheet metal screws shall generally be steel, with zinc coating, but will match the duct material in which installed. Standard or self-drilling sheet metal screws may be used as appropriate. Blind Rivets using pull-through mandrels are not permitted if they leave holes for air leakage. Fasteners will not project into duct interior more than 12 mm.
Duct Support: Except as otherwise indicated, support materials will match ducts; Fasteners, straps, rods threaded both ends, rods threaded one end, rods continuously threaded, trim and angle for support of ductwork. Securing ductwork to the support by sheet metal screws will not be allowed. 1.5 mm galvanized steel straps, 25 mm wide, will be used for ducts up to 1500 mm max dimension, 40 mm wide for larger ducts.
All dampers including pressure test points and locking mechanisms will be accessible and face the commissioning engineer and maintenance personnel.
