Handling & Installation
The Greenheck Vektor-H laboratory exhaust system is shipped in subassembly sections for easy rigging
and installation. Depending on the options ordered, the sections can include: Roof Curb, Bypass Air Plenum
Assembly, Blower Assembly, Stack Extension, and Discharge Nozzle.
The Vektor-H is designed to be self-supporting and standing (without the use of guy wires) when assembled per
the instructions provided within this manual. The roof curb must be securely fastened to the roof structure in
accordance with the contract documents. All subassembly sections have lifting lugs as shown.
Lifting lugs on each subassembly are designed to handle the weight of the subassembly section only.
Do not attempt to lift the entire system as a complete assembly.

Installation Instructions
Note: When installing each section, be sure to rig each piece
separately using the lifting lugs provided.
1. Mount roof curb to roof deck in accordance with local codes.
2. Install 3/16-inch thick x 1/2-inch wide, closed-cell neoprene gasket
on the top edge of the curb, adhesive side down (gasket provided).
Leave no gaps between gasket sections to ensure tight seal.
3. Place the bypass air plenum (BAP) onto the previously installed
gasket and secured roof curb. If a BAP is not provided for the unit,
skip to Step 5. Pre-drill pilot holes into the roof curb and attach
the BAP to the roof curb using the provided 5/16-inch self-tapping
screws. Screw fasteners are to be installed in all pre-punched curb
holes.
4. Install 3/16-inch thick x 1/2-inch wide, closed-cell neoprene gasket
on the top edge of BAP, adhesive side down (gasket provided).
Leave no gaps between gasket sections to ensure a tight seal.
5. Place the curb cap of the fan housing onto the gasket and BAP
(onto roof curb if BAP is not provided). Attach the curb cap
using the provided 5/16-inch self-tapping screws. If a BAP is not
provided, pilot holes must be drilled into the roof curb.
6. Install the final nozzle subassemblies as shown in the submittal
drawing. Align flange bolt holes and fasten sections using the 316
stainless steel bolts, washers, and lock washers provided.
7. Follow electrical connection and pre-start-up checks as listed on
