Your ventilation system should be installed in conformance with the appropriate provincial or state requirements

or, in the absence of such requirements, with the current edition of the National Building Code, and / or

ASHRAE’s “Good Engineering Practices”.

IMPORTANT - PLEASE READ THIS MANUAL

BEFORE INSTALLING UNIT

CAUTION - Before installation, careful consideration must be given to how this system

will operate if connected to any other piece of mechanical equipment, i.e. a forced air furnace

or air handler, operating at a higher static pressure. After installation, the compatibility of the

two pieces of equipment must be confirmed by measuring the airflow of the Heat Recovery

Ventilator using the balancing procedure found in this manual.

It is always important to assess how the operation of any HRV may interact with vented com-

bustion equipment (i.e. Gas Furnaces, Oil Furnaces, Wood Stoves, etc.).

NEVER - install a ventilator in a situation where its normal operation, lack of operation or par-

tial failure may result in the backdrafting or improper functioning of vented combustion equipment!!!

DETERMINING YOUR AIRFLOW REQUIREMENT Example for maximum airflow normally required. HRVs are typically sized to ventilate the whole house at a minimum of 0.35 air changes per hour. To calculate, simply take the square footage of the house (including basement) and multiply by the height of the ceiling to get the cubic volume. Then, divide by 60 and multiply by 0.35.

HRV INSTALLATION LOCATION PRACTICAL TIPS • Have a nearby power supply (120 Volts, 60Hz). • Choose a location which allows the possibility of mounting the unit to supporting beams. • The unit should be level in order to allow proper condensate drainage. The HRV must be located in a heated space where it will be possible to conveniently service the unit. Typically the HRV would be located in the mechanical room or an area close to the outside wall where the weatherhoods will be mounted.

EXTERIOR DUCTING INSTALLATION WEATHERHOOD LOCATION • Decide where your intake and exhaust hoods will be located.
PAGE 8
INTERIOR DUCTING INSTALLATION GENERAL TIPS To maximize airflow through the ductwork system, all ducts should be kept short and have as few bends or elbows as possible. 45º elbows are preferable to 90º. Use “Y” tees instead of 90º elbows whenever possible. All duct joints must be fastened with screws or duct sealant and wrapped with aluminium foil duct tape to prevent leakage.

START UP PROCEDURE Every time the unit is plugged in, it will go through a 45 second self diagnostic. During this time, the fresh air fans will not turn on. The switch on the side of the unit is used to toggle between STANDBY, LOW speed and MEDIUM speed modes. In order to activate HIGH speed, a jumper must be placed between the DEHUM + and DEHUM - contacts. Airflow Balancing WARNING If the unit’s air flows are not properly balanced… – The unit’s efficiency may be reduced.
PAGE 14
AIRFLOW BALANCING (CONT'D) ADJUSTING AIRFLOWS A damper is integrated into the Fresh Air to Building collar. This damper replaces the installation of a separate damper into the Fresh Air to Building ducting line. The damper-collar is pre-set in the fully opened position. If the procedure requires a reduction in airflow to the fresh air duct, simply turn positioning knob located on the side of the collar clockwise until desired airflow is obtained.

Low Voltage Control Systems * Please see instruction manuals for individual controls for proper wiring and set up of control systems. EDF1 EDF1R 2-wire connection •P ress button once for continuous low speed. • Pressing the button twice allows the HRV/ ERV to run a continous cycle of 20 minutes on and then standby for 40 minutes. • Press the button a third time and the system will run continuously on high speed. • Use in one central location.

TROUBLESHOOTING Problem Causes Solutions Air is too dry – Dehumidistat control is set too low – Increase the desired level of humidity. Change ventilation mode from continuous mode to standby. – Have contractor balance HRV airflows – HRV out of balance Air is too humid – Dehumidistat control is set too high – Dryer vent exhaust is inside home – Reduce the desired level of humidity. Combine this with the use of continuous exchange mode. – Wait until outside temperature stabilizes (winter).
