TYPICAL INSTALLATIONS Installations may vary according to the type of unit and the ports configuration (top or sides). Use the following illustrations as guidelines to help you decide on how the unit will be installed. All the units should be hung from the joists. In every case, bathroom fans and a range hood should be used to exhaust stale air. Also, for homes with more than one level, we recommend one exhaust register at the highest level. There are 3 installation methods: Fully ducted, Central Draw Point and Simplified Installation. NOTE: An electrical outlet has to be available within 3 feet of the unit. 2.1 FULLY DUCTED SYSTEM (PRIMARILY FOR HOMES WITH RADIANT HOT WATER OR ELECTRIC BASEBOARD HEATING.) 2.2 CENTRAL DRAW POINT (CONNECTION TO A FORCED AIR SYSTEM.) For this type of installation, it is not essential that the forced air system blower runs when the unit is in operation, but we recommend it. NOTE: Home with multiple forced air systems should have one unit on each system. Stale air coming from the registers located at the highest level of the house is exhausted to the outside. Fresh air from outside is filtered and supplied by the register located in the lowest liveable level. Homes with more than one level require at least one exhaust register at the highest level. See figure at right. Stale air coming from the registers located at the highest level of the house is exhausted to the outside. Fresh air from outside is filtered and supplied to the return (plenum) or the supply duct of the forced air unit. See figure at right. Stale air is exhausted to the outside. Fresh air from outside is filtered and supplied to the return (plenum) or the supply duct of the forced air unit. See figure at right. NOTE: It is possible to connect the outside fresh air duct to the supply duct of the forced air unit.To do so, the Automatic fresh air bypass must be used (part #: 15391). (See installation sheet included with the Automatic fresh air bypass). To avoid cross-contamination and achieve the highest efficiencies, the Automatic fresh air bypass (part #...
