3.0 Installation Preparation

3.1 Drain Trap Preparation

It is suggested that the condensate drain elbow and horizontal drain pipe be installed before the unit is set in its final position.

3.2 Unit Storage

If a DOAS must be stored before final placement, it requires a firm, level base. Prevent racking, which can cause doors and panels to bind. Cover units with protective tarps to prevent water and dirt entry through duct openings. Do not use the DOAS for storing construction supplies. Secure all doors and access panels.

3.3 Rooftop Curbs

Rooftop curbs are ordered and delivered separately and must be assembled per furnished instructions. Verify unit clearances against dimensioned drawings. Level curbs from the underside to ensure a continuous, level bearing surface for the DOAS. If a curb is placed above structural members, use shims beneath the curb at structural member locations to distribute the load. Shims are also required at lifting lug locations and every four feet. The bearing surface (top) of the curb must be within 1/8" of level per four-foot distance, with the front-to-back level at the drain pan being critical. After leveling, install the provided foam gasketing on the curb's top surface.

3.4 Curb Clips

Optional curb clip kits are available for DN-Series units, designed for winds up to 90 MPH. Install clips and hardware per instructions before placing the DN unit on the curb. Refer to the DN Curb Clip Installation Manual for details.

Diagram showing a typical installation of RenewAire curb clips.

3.5 Equipment Rails

Commercially available equipment rails can be used for rooftop or indoor installations. Ensure rails are sized to properly support the DOAS. Verify unit clearances against dimensioned drawings. Level rails within 1/8" of level per four-foot distance and ensure direct bearing support on building structural members.

3.6 Pre-Position Ductwork

For units with underside ductwork, pre-position the ductwork and install any needed gasketing on connecting surfaces. Ensure ductwork does not interfere with unit movement and placement.

3.7 Lateral Ground Movement

If the DOAS must be moved laterally on the ground to its final position, the installer must ensure proper support and safe movement. Moving the unit on its pallet is often preferable for better support and forklift use.

3.8 Unit Placement

Hoist the unit directly above its intended location (curb or rails) and lower it straight down. If using a RenewAire curb, foam gasketing will be applied. Avoid lateral adjustments that could damage the gasketing.

⚠️ CAUTION

It is the installers responsibility to select equipment, structures, and materials suitable to support the loads and substrates involved with installation. Secure the unit so it cannot fall or tip in the event of accident, structural failure, or earthquake. Do not store or stack items on the unit when installed.

3.9 Installation of Hoods

Rooftop units (RT models) include weatherhoods shipped separately for field installation. Install hoods after rigging and hoisting are complete to prevent damage.

All weatherhoods have a top rear flange that inserts behind the roof panel overhang. To install, remove and re-use factory-installed roof edge screws.

3.9.2 Exhaust Air Hood

Diagram of an Exhaust Air (EA) Hood with an insertion flange.

Installation: Slide the top flange under the roof panel back trim. Reinstall hood flange screws and then install screws along the sides and bottom edge of the hood.

3.10 Utility and Mechanical Connections

Make utility and mechanical connections after the unit is placed and hoods are installed. Structural alterations must comply with all applicable building, health, and safety codes. Avoid damaging electrical wiring or other utilities when cutting or drilling.

Unit labels indicate locations for field-supplied high voltage power and low voltage control wiring entry. Wiring penetrations outside designated locations must follow local code.

Indoor units with coils have connections at the front. Rooftop units with DX coils have connections at the back. Rooftop units with fluid (water) coils connect at the back, inside the unit. An area at the back of the unit is available for piping penetrations through the floor and curb.

Units with gas heat have connections at the front.
