DIMENSION

The SMART AIR HOOD® (SAH) Balancing Instrument is the most accurate and easy- to-operate air flow hood on the market today. The low profile design allows balancers to work in occupied spaces (bathroom stalls, MRI machines, cubicles, tables/chairs, etc.) and maneuver through doorways easier. By using the included 12-foot hood pole and wireless communications to a mobile device, one operator can balance a branch in less time than traditional balancing teams. Besides being lighter than most traditional capture hoods, the ergonomic design makes the technician exude less energy as the SAH has a lighter, balanced design. The rugged polypropylene base hood features Quad Flow Design Technology for controlling air flow and minimizing back pressure, which yields superior measurement accuracy. The Wi-Fi protocol back to the user’s Android® or iOS® device gives the user real-time feedback, as they may be up to 200 yards (183 m) from the hood which saves the technician from unnecessarily going up and down their ladder multiple times to cut or open the dampers to balance the system. The SMART AIR HOOD® Application Software reduces the number of steps in the air flow balancing process using Predictive Balancing. Predictive Balancing is a method of predicting the optimal flow set point for each register and the order in which they should be adjusted.

INTRODUCTION

WARNING Do not use the hood unit for liquid or gas mixtures other than air. No responsibility will be taken by Dwyer Instruments, LLC for any resulting damage to the unit or to the operator if it is used with corrosive or dangerous or explosive gas mixtures. When using the hood to check air flow at ceiling diffusers, make certain that you can raise and hold the unit safely during use. This instrument is not classified as flameproof or intrinsically safe; therefore, it must not be used where an explosion hazard may exist. The unit is not authorized for use on life support applications.
Note: Observe standard safety procedures when working on ladders and scaffolding. Also, ensure the unit does not become caught in moving machinery or on sharp objects.

CAUTION

• If stored under conditions outside normal operating range, allow the unit to stabilize at room conditions before use.
• Owing to its size and shape, take care when carrying the assembled unit from place to place.
• Avoid people and nearby equipment.
• Avoid objects that may damage the capture hood.
• Turn the instrument off before storage or transportation and remove the batteries if storing for long periods of time.
• Avoid subjecting the quad flow sensing grids to excessive loading during use or assembly. Any air flow other than through the calibrated sensing holes, such as any hair-line cracks, will seriously affect the sensitivity. A damaged quad flow sensing grid must be replaced. It cannot be repaired.
• Do not disassemble the quad flow sensing grids from the capture hood while taking readings or balancing. The retaining structure is specifically designed to accommodate loading due to normal operation.
• Under low humidity conditions, static electric charges may be encountered. These can be avoided by applying a suitable anti-static solution.

SETUP Battery Requirements

SAH Battery

WARNING Fire Hazard While Charging Battery Match the lithium-ion battery polarity symbols on the battery to the polarity symbols inside the battery bracket. Failure to do so may result in personal injury or property damage. The orientation of the polarity symbols on the battery must match the orientation of the label inside the SAH battery bracket (+ to +, – to -). The positive terminal of the NCR18650B battery is also marked by a wide black band on the battery. If a SAH-22-IN (less battery) was purchased, a 3.6 V NCR18650B lithium ion battery, or the equivalent, needs to be purchased from a local supplier and installed properly before the SMART Air Hood® Balancing Instrument can be operational.
Before beginning use with the SAH, it is suggested that the unit be charged using the included charging cable. Plug the mini-USB end of the cable into the unit’s charging port and the USB end into the charging block.

Battery Backup

Four AA batteries can be used as a backup for the lithium ion rechargeable battery, in case it loses charge during a job.

WARNING Be sure to install batteries correctly.

To turn off the hood, press and hold the power button until the LEDs turn off.

INSTALLATION

Assembling Accessories

In order to place the hood onto a diffuser to measure air flow it needs to be mounted to one of the two provided poles. To connect the pole to the hood, align the hole at the end of the pole with the holes in the mounting plate of the hood. Insert the provided locking pin through the holes in order to lock the pole to the hood. When inserting the locking pin, start by placing it into the alignment hole on the opposite side from the power button as illustrated below. In order to insert or remove the pin, press in the button on the end of the pin.

When using the short pole or with the SAH adapter base kit for canvas hoods, the stationary pole adapter should be used to keep the hood pole from pivoting. Place the stationary pole adapter onto the SAH and attach using the screws and wing nuts provided (below). Once secure to the SAH, insert the short pole and secure in place using the locking pin.

To attach a mobile device to the pole, attach the locking attachment to the mobile device case as shown below. Secure the mobile device to the pole using locking attachment by inserting it into the locking device on the pole and rotating 1/4 turn.

Once the mobile device is attached to the pole, the SMART Air Hood® balancing instrument is now ready for use. For shorter ceilings it is recommended to leave the top section of the pole inserted into the pole and adjust the height with the middle section for greater stability.
