2. 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. If required, bathroom fans and a range hood may 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.
2. TYPICAL INSTALLATIONS (CONT’D) 2.4 ATTIC INSTALLATION FOR ERV EKO 1.5 ONLY All three types of installation can be used in the attic (Fully ducted, Central Draw Point or Simplified). The example shown below is a Simplified Installation (connection to a forced air system). NOTE: To get the most of your ERV unit, the ambient temperature around the unit should be conditioned.
3. INSTALLATION (CONT’D) 3.4 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. 3.
3. INSTALLATION (CONT’D) 3.6 INSTALLING THE DUCTWORK AND REGISTERS 3.6.1 FULLY DUCTED SYSTEM (AS ILLUSTRATED IN SECTION 2.1) ! WARNING Never install a stale air exhaust register in a closed room where a combustion device operates, such as a gas furnace, a gas water heater or a fireplace. Stale air exhaust ductwork • Install the stale air exhaust registers where the contaminants are produced: kitchen, living room, etc.
3. INSTALLATION (CONT’D) 3.6 INSTALLING THE DUCTWORK AND REGISTERS (CONT’D) 3.6.3 SIMPLIFIED INSTALLATION (AS ILLUSTRATED IN SECTION 2.3) ! 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 (Method 1), this duct must be sized to support the additional airflow produced by the unit.
3. INSTALLATION (CONT’D) 3.7 CONNECTING THE DUCTS TO THE UNIT Insulated flexible ducts Use the following procedure to connect the insulated flexible ducts to the ports of the unit (Exhaust air to outside and Fresh air from outside ports). CAUTION If ducts have to go through an unconditioned space (e.g.: attic), always use insulated ducts. 1. 2. 3. 4. Pull back the insulation to expose the flexible duct. Attach the flexible duct to the port using tie wrap.
3. INSTALLATION (CONT’D) 3.8 INSTALLING TWO EXTERIOR HOODS Choose an appropriate location to install the exterior hoods: • There must be a minimum distance of 6 feet (1.8 m) EXHAUST HOOD between the hoods to avoid cross-contamination • There must be a minimum distance of 18 inches (457 mm) from the ground 6" Ø (152 MM) OPTIONAL DUCT LOCATION INTAKE HOOD 18" (457 MM) ! WARNING 6' (1.8 M) Make sure the intake hood is at least 6 feet (1.
4. CONTROLS All units are equipped with an integrated control located under the unit, on the recessed side of electrical compartment. Plug the unit. 4.1 UNITS BOOTING SEQUENCE The unit booting sequence is similar to a personnal computer boot sequence. Each time the unit is plugged after being unplugged, or after a power failure, the unit will perform a 30-second booting sequence before starting to operate. 4.1.1 ERV EKO 1.5, HRV EKO 1.
4. CONTROLS (CONT’D) 4.3 SPEED AND DEFROST SETTINGS FOR ERV EKO 1.5, HRV EKO 1.5, ERV 90H-V ECM AND HRV 90H-V ECM UNITS The special design of ERV EKO 1.5, HRV EKO 1.5, ERV 90H-V ECM and HRV 90H-V ECM units offers 4 speed ranges to better meet to different ventilation needs. Refer to the table below to choose the right speed range according to the size of the house: CFM VALUES NOTE: These CFM values are approximate, they may vary according to the installation static pressure. SPEED RANGE HRV MIN.
4. CONTROLS (CONT’D) 4.5 ELECTRICAL CONNECTION TO MAIN CONTROLS For more convenience, these units can also be controlled using an optional main wall control. NOTES: 1. The integrated control must be turned OFF 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. ! WARNING Always disconnect the unit before making any connections.

5. 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.
