External brackets, one for each side, transition and connect lower section
of the bypass air plenum to the ERS plenum cabinet. These brackets ship
with the BAP and also complete the connection between the BAP and
roof curb.
6. Fan rigging, lifting and installation
After the ERS and Vektor fan BAP are joined and secured, the Vektor-M fans can be set on the BAP. Refer to the
Vektor-MH, Vektor-MD and Vektor-MS installation instruction, document number 464652 for this procedure.
Assembly and Installation (Vektor-C)
1. Assemble factory supplied roof curbs
Roof curbs are modular in construction and require field assembly.
Each roof curb will arrive in sections along with an assembly kit for field installation. Verify all roof curb sections
and assembly kit(s) have arrived for each fan mark and are in good condition prior to signing the shipping receipt.
Use one Roof Curb Assembly Kit with gasketing and hardware for each section to be joined. Attach self-adhering
foam gasketing (supplied) to one side of either joining section (see Drawing 1a). Gasketing should be placed to
form a continuous seal. Corner locations may need second strip to cover seam joints. Supplied hardware should
then be used to secure the two sections together as shown (see Drawing 1b). Hold nut with wrench while bolt is
tightened.

Tighten the bolt-washer assemblies to the top and both sides of the joining
sections. Start on the lower sides and work towards the top. As the bolts are
tightened, the plenum sections will draw together. Use anti-seize gel to prevent
galling / welding of all stainless steel fasteners. If necessary, pull the units together
with a mechanical come-along device at the structural base of the unit or at lifting
lugs.
