Plenum Service Clearances and Access Locations

ERS plenum cabinet and Vektor fan bypass air plenum (BAP) require minimum clearances for access on three sides for routine maintenance. Filter replacement, drain pan inspection and cleaning, coil inspection, damper actuator adjustments and inspection, fan bearing lubrication and belt adjustment (belt drive units), are examples of routine maintenance that must be performed. Coil and filter sections are always provided with a service door or panel for proper component access. Clearances for component removal may be greater than the service clearances. Refer to page 12 for coil clearances.

NOTE

Gasketing material (shipped with Vektor fan) should be placed on the top edge of secured roof curb prior to placing the ERS plenum cabinet and Vektor bypass air plenum on the curb.

NOTE

If fan bypass air plenum (BAP) is in sections, these should be assembled first, prior to connection to ERS plenum cabinet. Refer to Vektor Fan IOM (part number 464652) on how to assemble the fan BAP.

Determine the placement of the plenum sections relative to each other. Please refer to the submittal drawing for the orientation of any bypass air plenum

2. Cut roof opening and locate curb

Layout the unit roof openings such that exhaust

inlet of the unit will line up with the corresponding

ductwork (refer to Recommended Roof Openings

on page 7). Do not make opening larger than

necessary. Be sure to allow for the recommended

service clearances.

3. Install roof curbs

Locate curb over roof opening. Check that the

diagonal dimensions are within ±1⁄8 inch of each

other and adjust as necessary. Shim as required

to level. Secure curb to roof deck. Attach

supplied gasketing to top of curb.

Assembly of Roof Curbs and ERS Plenum Cabinet to the Bypass Air Plenum (BAP)

Rooftop units require curbs to be mounted first. The duct connections must be located so they will be clear of structural members of the building.

1.Assemble factory supplied roof curbs

Roof curbs are Model VK-ERS, which are shipped knocked down and require field assembly (by others). Assembly instructions are included with the roof curb.

4. Set the ERS plenum cabinet

Lift ERS plenum cabinet to a point directly above

the curb and duct openings. While lowering,

guide cabinet to align with duct opening. Roof

curbs fit inside the unit base. Set ERS plenum

cabinet into place on assembled VK-ERS roof

curb. Allow gasketing on curb to compress before

setting the fan bypass air plenum. Make sure the

unit is properly seated on the curb and is level.
