MOUNTING

The Spruce RB Series Fans may be mounted at any angle without affecting performance although the vertical mounting position shown in Fig. 1 is highly recommended. If the vertical mounting position is not possible, care should be taken to avoid creating a low spot in the fan/duct system where condensation might accumulate in the fan housing as shown in Fig. 2. In situations where horizontal mounting is desired and condensation is likely to occur (bathroom ventilation in cold climates), this problem might be avoided by mounting the fan 30 degrees beyond horizontal as shown in Fig. 3.

FAN SEALING

RB Series Fans are factory sealed, no additional caulk or other materials are required to inhibit air leakage.

DUCTING

Any type of ducting is acceptable, however, flexible nonmetallic ducting is recommended for easy installation and quieter operation. Insulated flexible ducting is highly recommended in cold climates to prevent the warm bathroom air from forming condensation in the ducting where it is exposed to colder attic air. The outlet of the fan should always be ducted to the outside. Avoid venting the outlet of the fan directly into an attic area. The excess moisture from the bathroom can cause damage to the building structure and any items stored in the attic. Multiple venting points may be connected together using a T or Y fitting. Ideally, the duct should be arranged such that equal duct lengths are used between intake and T or Y fitting, this will result in equal flow rates in each intake branch. If adjustable intake grilles are used on multi-intake systems, then the opening on each grille should be equal in order to minimize noise and resistance. Straight smooth runs of rigid metal ducting will present the least resistance and maximize system performance. The Equivalent Length of Rigid Metal Ducting resulting in .2” WC pressure loss for each fan model is provided in the specification section of these instructions. Flexible ducting, if used, must always be as close to being fully extended as possible. Formed rigid metal duct elbows will present the least resistance and maximize system performance, recommended bend radius of the elbow is at least 1.5 x duct diameter.
To ensure the quiet operation of our inline and remote fans, each fan shall be installed using sound attenuation techniques appropriate for the installation. For bathroom and general ventilation applications, at least 8 feet of the insulated flexible duct shall be installed between the exhaust or supply grille(s) and the fan. RB Series Fans are not suitable for kitchen range hood remote ventilation applications. The ducting from this fan to the outside of the building has a strong effect on the airflow, noise, and energy use of the fan. Use the shortest, straightest duct routing possible for best performance, and avoid installing the fan with smaller ducts than recommended. Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed with existing ducts may not achieve their rated airflow.

BACKDRAFT DAMPERS

Backdraft dampers allow airflow in only one direction preventing cold/hot drafts from entering the vented area and minimizing possible condensation and icing within the system while the fan is not operating. Backdraft dampers are highly recommended at each intake grille for bathroom ventilation in all cold climate installations. Installation instructions are included with Spruce backdraft dampers.

ELECTRICAL WIRING

All wiring must be performed in accordance with the National Fire Protection Association’s (NFPA) ”National Electrical Code, Standard #70” current edition for all commercial and industrial work, and state and local building codes. All wiring must be performed by a qualified and licensed electrician. A Ground Fault Interrupter (GFI) circuit is not required in most installations; check your local codes. Ensure that all exterior electrical boxes are outdoor rated and properly sealed to prevent water penetration into the box. A means, such as a weep hole, is recommended to drain the box. Note that the fan is not intended for connection to the rigid metal conduit.

APPLICATIONS

Suitable for general ventilation, bathroom venting, fresh air supply, duct boosting, building pressurization, etc. RB Series Fans are not suitable for kitchen range hood venting.

INSTALLATION

Step 1: Install Mounting Bracket as shown (Fig. 4) (RB110, RB190 & RB275 only; separate instructions for RB400 & RB500 are included with Mounting Bracket Kit). Insert Grommets into slots in Mounting Bracket. Orient the Electrical Box relative to Mounting Bracket as required. Attach the fan to the Mounting Bracket with 3 #10 self-tapping screws, provided. Avoid over- tightening screws.
Step 2: Select the location for fan mounting. A location 2/3 along with the ducting, a minimum of 10 feet away from the inlet vent to the fan or the T/Y of a multi-intake system —will provide the quietest operation. The fan should be mounted vertically to prevent moisture from accumulating in the fan housing. Attach the bracket to the mounting structure with the 1 1/4” screws provided (Fig. 5).
Step 3: Connect ductwork between the fan inlet and the area to be vented through the inlet grille (Fig. 6). Flexible, non-metallic ducting is recommended for the quietest operation and easiest installation. Insulated flexible ducting is highly recommended for bathroom ventilation in all cold climate installations. Metal worm drive clamps, spring clamps, and adjustable plastic ratchets are recommended for the connection of ducting. Silicon caulk or duct tape may be used for additional sealing. Duct tape should be used to retain insulation.
Step 4: Connect inlet grille(s) (Fig. 7). An optional backdraft damper may be installed in the inlet grille to prevent cold air from backing into the inlet, prevent conditioned air from escaping and also prevent condensation from forming inside the ductwork. Backdraft dampers are highly recommended at each intake grille for bathroom ventilation in all cold climate installations.
Step 5: Connect the outlet of the fan to the outside vent (Fig. 8). The outside vent may go through the roof, sidewall, or soffit as desired. Flexible, nonmetallic ducting is recommended for the quietest operation and easiest installation. Insulated flexible ducting is highly recommended for bathroom ventilation in all cold climate installations.
Step 6: Make an electrical connection to the fan (Fig. 9). Ensure any metal filing used in the installation is properly grounded. A plastic cable connector such as a T&B #3300 may be used to avoid any filing grounding problem. Observe the proper wiring connections (See Section 5.0). Note that the fan is not intended for connection to the rigid metal conduit.
