1. YOUR UNIT AND ITS PURPOSE 1.1 UNIT DESCRIPTION 1 1. 2. 3. 4. Filters Blower Recovery core Condensation tray 1 3 2 4 VL0052 1.2 PURPOSE OF THE VENTILATION SYSTEM Your ventilation system is designed to provide fresh air, warmed outdoor air to your home while exhausting stale, humid air from your home. By eliminating accumulated pollutants and humidity, it maintains an optimum air quality and an ideal relative humidity. VH0078 NOTES: 1. Shown with a forced air system. Can also operate on its own. 2.
1. YOUR UNIT AND ITS PURPOSE (CONT’D) 1.3 RECOVERY 1.3.1 HEAT RECOVERY CORE Units with a heat recovery core (HRV Constructo 1.5ES and HRV Constructo 2.0ES units) are designed specifically to control excess humidity and reduce ventilation costs by recovering the heat energy from the exhausted air, and using that same heat energy to warm the fresh air being supplied. This heat recovery process is accomplished in such a way that the stale air is never mixed with the fresh air.
1. YOUR UNIT AND ITS PURPOSE (CONT’D) 1.4 DEFROST MODE When the outdoor temperature is below -5°C (23°F), recovery (of heat or energy) creates frost in the module. To maintain its proper operation, the unit is programmed to defrost the recovery module. The defrost frequency varies according to the outdoor temperature. Defrost lasts 7 minutes for HRV Constructo 1.5ES, 6 minutes for HRV Constructo 2.0ES and 10 minutes for ERV Constructo 2.0ES models (or 10 minutes for all models if set on “Extented Defrost”).
2. CONTROLS 2.1 INTEGRATED CONTROL These units are equipped with an integrated control, located on the electrical compartment. Use the push-button (1) to control the unit. The LED (2) will then show on which mode the unit is in. 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, the operation of this auxiliary control will override the optional main control operation. 2 1 Refer to table below.
3. MAINTENANCE ! WARNING Dangerous voltage may be present. During maintenance and repairs, the unit must always be turned off, then unplugged. We take great care to minimize sharp edges; however, please proceed with caution when handling all components. When cleaning the unit, it is recommended to wear safety glasses and gloves. Regular maintenance should be performed every 3 months. Annual maintenance should take place every fall season. 3.1 EVERY THREE MONTHS 1. Disconnect power supply. 2.
3. MAINTENANCE (CONT’D) 3.2 ANNUAL MAINTENANCE (FALL) 3.2.1 HEAT RECOVERY CORE Repeat steps 1 to 6 from the Section 3.1 and continue with the following steps: CAUTION Hot water and a strong detergent will damage the heat recovery core. 1. Clean the heat recovery core: • Remove core. • Let it soak in a mixture of cold or lukewarm water and mild soap (dishwashing liquid). • Rinse thoroughly. • Shake the core to remove excess water and let it dry. 2. Clean blower assembly.
4. TROUBLESHOOTING PROBLEM YOU SHOULD TRY THIS 1. Nothing works. • See if the unit is plugged in. • See if the unit is receiving power from the house circuit breaker or fuse. 2. Noisy unit. • Clean the unit (see Section 3). If the problem is not solved, contact your installer. 3. Condensation on windows (air too humid). • Operate the unit at maximum speed (MAX.) during activities generating excess humidity (family gatherings, extra cooking, etc.). • Leave curtains half-open to allow air circulation.
