3002443 04.14 3. Mechanical Installation 3.1 Positioning The ventilator can be installed in many different positions. However, it should always be possible to open the access door at least 80 degrees, and the locking bolts should always be accessible. Acceptable ventilator positions are shown below in Fig. 3. Note that the ventilator motor can never point straight down as this could cause condensation build-up around the shaft, which can shorten the product life.
3002443 04.14 3.3 Ceiling Mounting The box ventilator can be mounted with plumber’s strap or threaded rod with nuts and washers, or it can be placed on support legs (included). As Fig. 6 illustrates, the ventilator can be placed in virtually any position or direction, except with the motor pointing down. When placing the venter on the support legs (1), the vibration dampers (4) should be used and secured by nuts (2).

All electrical wiring must be in accordance with requirements of authority having jurisdiction or, in absence of such requirements, with National Electrical Code NFPA 70 — latest edition.
3002443 04.14 5. Start-up and Configuration 5.1 System Testing Before any adjustments are made to the system, follow these procedures: 1. Turn the fan ON and make sure that it is operating. Increase and decrease the speed of the fan by adjusting the fan speed control to make sure it is operating properly. 2. Turn the fan OFF and make sure the pressure switch opens, so the power to the circuit, it controls, is disconnected. DANGER Check other heating appliances (water heater, furnace, fireplace etc.
3002443 04.14 6. Maintenance & Troubleshooting 6.1 Cleaning Intervals The ventilator is designed for prolonged use. It must be inspected and cleaned at least every 12 months. The need for cleaning is dependent on the type of application and how the ventilator is operated. 6.2 Cleaning Deposits should be removed from the impellers and the bottom of the ventilator: 1. 2. 3. 4. 5. 6. Turn the fan off at the repair switch. When the blower wheel no longer rotates, open the access door.
3002443 04.14 6.3 Troubleshooting Problem Probable Cause What to do Fan is making too much noise. Ducting is too small for the volume of the air. Resize ducts. Ducts/Filters are dirty/clogged. Clean and inspect ducts and filters. Fan inlet or outlet is too close to the customer. Relocate duct or fan. Damaged during shipping or installation.
