3. TYPICAL INSTALLATIONS The figure below illustrates a typical installation. The fresh air intake hood must be located at least 6’ away from the outdoor exhaust hood (measurement A), the fresh air from outside duct must be at least 6’ away from the furnace (measurement B) and the stale air from inside duct must be at least 18” from the furnace (measurement C). Ducts connected to outdoor hoods must be insulated. VH0080 4. INSTALLATION 4.
4. INSTALLATION (CONT'D) 4.2 CONNECTING DUCTS TO THE UNIT INSULATED FLEXIBLE DUCTS: Use the following procedure for connecting the insulated flexible ducts to the ports on the unit (exhaust to outside and fresh air from outside). a) Pull back the insulation to expose the flexible duct. b) Connect the interior flexible duct to the opening using a duct tie. c) Carefully seal the connection with duct tape. d) Pull the insulation over the joint and tuck it between the inner and outer rings of double collar.
4. INSTALLATION (CONT'D) 4.4 CONNECTING THE DRAIN Cut 2 sections of the plastic tube, at least 16” long, and attach them to each inner drain fitting, located under the unit. Join both short sections to the “T” junction and main tube as shown. 16” 16” VO0177A Make a water trap loop in the tube to prevent the unit from drawing unpleasant odors from the drain source. Make sure this loop is located OVER the “T” as shown. Run the tube to the floor drain or to an alternative drain pipe or pail.
5. AIR FLOW BALANCING (CONT'D) Preliminary Stages for Balancing the Unit: Seal all the unit ductwork with duct tape. Close all windows and doors. Turn off all exhaust devices such as: range hood, dryer and bathroom fan(s). Make sure balancing dampers are fully opened (F and G in figure below). Choose appropriate locations for the 2 flow collars according to figure below: • On the exhaust air duct (first measuring location, A). • On the fresh air distribution duct (second measuring location, B).
5. AIR FLOW BALANCING (CONT'D) Balancing Procedure (cont'd): 5. If the furnace has a low speed option, select the low speed option and check if the fresh air flow and the stale air flow are still balanced. 6. Remove flow collars, reconnect the ducts and seal with duct tape. Write the required airflow information on a label and stick it near the unit for future reference: date, maximum speed airflows, your name and phone number and business address.
7. MAINTENANCE ! WARNING We take great care to keep sharp edges to a minimum, but please be careful when handling components. Regular maintenance should be performed every 3 months. B Set the wall control to 80% (FAE125M or VFAE125M units only). A B C Remove both door lower screws no. 8-32 x 1” (A) and set aside. Open and lift out the door (B). VO0178 D Slide out the filter and vacuum to remove most of the dust. Wash with a mixture of warm water and mild soap.
8. TROUBLESHOOTING If you think your unit is malfunctioning, check the following: 1 PROBLEMS TRY THIS Nothing works (models FAE125M and VFAE125M only). • See if the transformer is plugged in. • See if the transformer is receiving power from the house circuit breaker. Condensation on windows (air too humid). • Adjust the humidity control knob as per instructions (see Section 6) (FAE125M and VFAE125M models only). • Leave curtains half-open to allow air circulation.
