TABLE OF CONTENTS 1. TYPICAL INSTALLATIONS ......................................................................................................................... 4-5 1.1 FOR HOUSE .................................................................................................................................................. 4 1.1.1 FULLY DUCTED SYSTEM ............................................................................................................................................4 1.1.
1. TYPICAL INSTALLATIONS 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 or ceiling using brackets (included with the unit). If desired, an optional chains and spring kit (part no. 61239, sold separately) can be used instead of brackets. If required, bathroom fans and a range hood can be used to exhaust stale air. Also, for homes with more than one level, we recommend one exhaust register at the highest level.
1. TYPICAL INSTALLATIONS (CONT'D) 1.2 FOR HIGH-RISE DWELLING 1.2.1 FULLY DUCTED SYSTEM (PRIMARILY FOR HOMES WITH RADIANT HOT WATER OR ELECTRIC BASEBOARD HEATING) Stale air coming from the registers located in bathrooms and kitchen is exhausted to the outdoors. Fresh air from outdoors is filtered and supplied by the registers located in bedrooms and living room. See figure at right. VH0095 1.2.
2. INSTALLATION (CONT’D) 2.3 LOCATING THE UNIT Choose an appropriate location for the unit. • Within an area of the house where the ambient temperature is kept between 65°F and 104°F. • So as to provide easy access to the interior of the unit, for quarterly and annual maintenance. • Close to an exterior wall, so as to limit the length of the insulated flexible duct to and from the unit. • Away from hot chimneys and other fire hazards.
2. INSTALLATION (CONT’D) 2.4 HOW TO HANG THE UNIT (CONT'D) Bend 90° integrated hooks (2 places). Hang the hooks onto the brackets. Clip the other side of unit onto the brackets (2 places). VD0338 ! WARNING Ensure the unit is completely held by the brackets before continuing the installation. NOTE: The unit can also be hung using 4 hooks (shaded part in illustration at right), chains, springs and screws (kit sold separately, part no. 61239). CAUTION Make sure the unit is level.
2. INSTALLATION (CONT’D) 2.5 PLANNING OF THE DUCTWORK • Keep it simple. Plan for a minimum of bends and joints. • Keep the length of insulated ducts to a minimum. • Do not ventilate crawl spaces or cold rooms. Do not attempt to recover the exhaust air from a dryer or a range hood. This would cause clogging of the filters and recovery module. • If the house has two floors or more, be sure to plan for at least one exhaust register on the highest lived-in level. 2.
2. INSTALLATION (CONT’D) 2.6 INSTALLING THE DUCTWORK AND REGISTERS (CONT'D) 2.6.2 CENTRAL DRAW POINT SYSTEM (AS ILLUSTRATED IN SECTIONS 1.1.2 AND 1.2.2) Stale air exhaust ductwork: Same as for Fully Ducted System, described on point 2.6.1 Fresh air distribution ductwork: ! WARNING When performing duct connections, always use approved tools and materials. Respect all corresponding laws and safety regulations. Please refer to your local building code.
2. INSTALLATION (CONT’D) 2.6 INSTALLING THE DUCTWORK AND REGISTERS (CONT’D) 2.6.3 SIMPLIFIED INSTALLATION (AS ILLUSTRATED IN SECTION 1.1.3) ! WARNING When performing duct connections, always use approved tools and materials. Respect all corresponding laws and safety regulations. Please refer to your local building code. CAUTION When performing duct connections to the furnace supply duct, this duct must be sized to support the additional airflow produced by the ERV. Also, use a steel duct.
2. INSTALLATION (CONT’D) 2.7 CONNECTING THE DUCTS TO THE UNIT NOTE: All units ports were created to be connected to ducts having a minimum of 5” diameter, but if need be, they can be connected to bigger sized ducts by using an appropriate transition (e.g.: 5” diameter to 6” diameter transition). Insulated flexible ducts: CAUTION Make sure the balancing dampers are set to wide open position before connecting the ducts to the ports.

3. CONTROLS 1 2 The ERV100SP unit is equipped with an integrated defrost control while the ERV100S unit has an integrated control. In both cases, those electronic devices are located under the unit, in front of the electrical compartment. Refer to the figure at right for steps 3.1 up to 3.4. Plug the unit. VC0152 3.1 BOOTING SEQUENCE The unit booting sequence is similar to a personnal computer boot sequence.
3. CONTROLS (CONT'D) 3.2 ERV100SP UNIT INTEGRATED DEFROST CONTROL After the booting sequence is done, the LED (1) will light and stay lit to show in which defrost cycle the unit is set. Use the push button (2) to change the defrost cycle of the unit (see table at right).
3. CONTROLS (CONT'D) 3.5 ELECTRICAL CONNECTION TO WALL CONTROLS The ERV100SP unit must be controlled by a main control. For more convenience, the ERV100S unit can also be controlled using an optional main control. NOTES: 1. The integrated control must be turned OFF on ERV100S unit to use an optional main control. 2. If an optional auxiliary control is used, if activated, this auxiliary control will override the optional main control operation.
3. CONTROLS (CONT'D) 3.5 ELECTRICAL CONNECTION TO WALL CONTROLS (CONT'D) 3.5.1 ELECTRICAL CONNECTION TO VT8W MAIN WALL CONTROL (ERV100SP UNIT ONLY) 3.5.2 ELECTRICAL CONNECTION TO VT7W MAIN WALL CONTROL (ALL UNITS) NO C NC I OC OL Y R G B MODE PREF SET NO C NC I OC OL Y R G B SMART VE0181 3.5.3 VE0250 ELECTRICAL CONNECTION TO VT4W MAIN WALL CONTROL (ALL UNITS) 3.5.
4. ELECTRICAL CONNECTION TO THE FURNACE ! WARNING Never connect a 120-volt AC circuit to the terminals of the furnace interlock (standard wiring). Only use the low voltage class 2 circuit of the furnace blower control. For a furnace connected to a cooling system: On some older thermostats, energizing the “R” and “G” terminals at the furnace has the effect of energizing “Y” at the thermostat and thereby turning on the cooling system.
