that it is in place and not

damaged or missing prior to joining the two plenums together.

Inside the ERS plenum are slots along the marrying sections

which accept the bolt and washer assemblies. Using the hardware kit,

attach the unit sections by bolting

together frame extrusion from the

inside.

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.

External brackets, one for each side, transition and connect lower section of the bypass air plenum to the ERS cabinet. These brackets ship with the BAP and also complete the connection between the BAP and roof curb.

The assembly hardware (stainless steel bolts) required to join the sections is located in the Vektor fan bypass air plenum accessory kit.

Lift and set the Vektor fan BAP on the curb against the ERS plenum. Follow rigging and lifting instructions in the Vektor-MD installation instruction (part number 464652). Push fan bypass air plenum tight against ERS plenum, making sure to line up bolt holes. Be certain to compress foam gasket to form an airtight seal.

After the ERS plenum and Vektor fan BAP are joined and secured, the Vektor fans can be set on the BAP. Refer to Vektor Fan installation instruction (part number 464652) on this procedure.

Installation

Installations with inlet configurations that deviate from this standard may result in reduced fan performance. Restricted or unstable flow at the fan inlet can cause pre-rotation of incoming air or uneven loading of the fan wheel yielding large system losses and increased sound levels.

Vektor Riser Installation

Check curb or structural supports for levelness. Both must be level to ensure proper drainage from plenum and fan(s).
