4. A short piece (1-2 foot) of flexible ducting should be used on both sides of the TFP (Fig. 3). This will reduce vibration and noise transfer if present. NOTE: Please refer to the HRV installation manual for proper ducting of that appliance. Type 2 Installation *“Breathing T” is designed to assist in neutralizing pressure differences which can occur between HRV and TFP when joined together. TFP Hanging straps (4) Relief opening (breathing T) 6" port collars Power cord Flexible ducting Air flow HRV To BRANCH LINES Mounting bolts Main supply trunk Flexible ducting TFP air cleaner FLOOR JOISTS or leave a 4" -6" (fresh air supply) Access door gap between the TFP and the HRV Figure 3 CAUTION The room in which the “breathing T” is open should be free of combustion equipment such as gas hot water tanks and furnaces. If the “T” must be exposed in these areas, a pressure test (spillage or backdraft test) should be conducted on the combustion equipment after everything is installed. 3 TYPE 3 INSTALLATION TFP Independent Installation Type 3 Installation No HRV, Radiant Heating System LOCATION 1. A TFP is usually installed in a basement area where air flow noise will be negligible to the occupants. 2. A central location between the clean air supply grille and return grille is recommended. MOUNTING Refer to “Mounting” under Type 2 Installations. DUCTING 1. Install (2) 6” oval port collars (provided) on TFP cabinet with (8)8/32” X 3/8” sheet metal screws provided (Fig.4). 2. Ducting will usually consist of one return with grille from one side of the home, and one supply with grille at the opposite end of the home (Fig. 4). 3. Ductwork should be no smaller than the size of the Figure 4 port collars (6”) on the TFP. FLOOR JOIST (Header) Return Grille High wall or floor grille optional 6" port collars Access door Hanging straps (2) Ducting not included BASEMENT High wall or floor grille optional 1st or 2nd STORY Clean air supply TFP 4. Ductwork should be kept as short and straight as possible to allow for good air circulation. NOTE: For installations of more than one return or supply (greater than .5 e.s.p.) , it is often necessary to add an inline fan to the system as a booster. OPERATING INSTRUCTIONS AND ANNUAL CHECK-UP OPERATING INSTRUCTIONS A lighted ON/OFF switch indicates that the unit is operating. It is recommended the unit run continuously to provide the full benefits of particulate removal from your home. ANNUAL CHECK-UP As each home has differences of size, occupancy, location, infiltration rates and homeowner needs, it is hard to estimate when the collectors will need to be changed. Because of the way air moves through the TFP, the collectors are divided into 3 separate sections. Collectors 1 & 2, then 3 & 4 and then 5 & 6. Collectors 1 & 2 will need to be replaced before the others, then 3 & 4 and so on. You may want to change 1 & 2 again before 3 & 4 or 5 & 6. The collectors will slide out. Some discolouration of the collector medium can be expected and when loose dust falls from the collector, it is time to replace it. Turn the TFP, furnace fan and HRV off. Open the door and slide out the collectors to check buildup and do an annual inspection of overall unit. Before replacing any collectors, vacuum any dust inside the cabinet or surrounding area. When replacing the collectors, make sure the pleats are horizontal when sliding collectors back into the TFP. Close the door and restart TFP, furnace and HRV fan. When your TFP is installed with a forced air heating system you are still required to use the recommended furnace filter. This may be a good time to inspect this filter as well. When new collectors are required, call your Lifebreath dealer. ...
