Item #: 427470 Rev Date: 2017-07-28 Installation Manual SER150 Energy Recovery Ventilators Your ventilation system should be installed in conformance with the appropriate provincial/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”.

Note Warning/ Important note Information Technical information Practical tip PLEASE READ THIS MANUAL BEFORE INSTALLING UNIT For residential use only 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.

INSTALLATION EXAMPLES Suggested installation for: • Hydronic baseboard • Infloor heating • Electric baseboard • Mini split heat pump Example only – duct configuration may differ depending on the model. FULLY DEDICATED SYSTEM BEST FOR NEW CONSTRUCTION 1. Stale air is drawn from key areas of the home requiring local exhaust (bathroom, kitchen, laundry room). 2. Fresh air is distributed directly to habitable rooms in the house (bedrooms, living room) 3.
INSTALLATION EXAMPLES (CONT'D) Suggested installation for: • Central furnace (air handling unit or central air conditioners) • When ducting fresh air to living area is not possible or practical, i.e. expensive or when the central AHU will operate year-round. DIRECT CONNECTION of the FRESH air to living area to the RETURN PLENUM of the AIR HANDLER (Stale air drawn from key areas of home) PARTIALLY DEDICATED SYSTEM (BETTER) 1.
INSTALLATION EXAMPLES (CONT'D) Suggested installation for: • When bathroom and kitchen already have local exhaust system • May be suitable for retrofitting DIRECT CONNECTION of both the ERV SUPPLY AIR STREAM and EXHAUST AIR STREAM to the FURNACE COLD AIR RETURN Benefits: Least expensive installation type SIMPLIFIED INSTALLATION (GOOD) (RETURN/RETURN METHOD) 1. Furnace blower must operate when ventilation from ERV is required. The furnace should be set to run continuously or interlocked with ERV.
EXTERIOR DUCTING INSTALLATION WEATHERHOOD LOCATION OUTSIDE CORNER • Decide where your intake and exhaust hoods will be located. INSIDE CORNER 36" (1m) Locating the Intake Weatherhood • Should be located upstream (if there are prevailing winds) from the exhaust outlet. • At a minimum distance to 900 mm (3') away from dryer vents and furnace exhaust (medium or high efficiency furnaces), driveways, oil fill pipes, gas meters, or garbage containers.
INTERIOR DUCTING INSTALLATION • 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“ ducts instead of “T” ducts whenever possible. • All duct joints must be fastened with screws or duct sealant and wrapped with aluminum foil duct tape to prevent leakage.
ERV INSTALLATION LOCATION The ERV must be located in a conditioned space where it will be possible to conveniently service the unit. Typically the ERV would be located in the mechanical room or an area close to the outside wall where the weatherhoods will be mounted. If a basement area is not convenient or does not exist, a utility room may be used.
INSTALLING DRAIN LINE Through normal operation and during its defrost mode, the ERV may produce some condensation. This water should flow into a nearby drain, or be taken away by a condensate pump. The ERV and all condensate lines must be installed in a space where the temperature is maintained above the freezing point. A “P” trap should be made in the drain line. This will prevent odors from being drawn back up into the unit.
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.
Observe polarity on all accessory controls where applicable.

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 ERV airflows ERV 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).
ERV MAINTENANCE CHART Limited Warranty Maintenance Required Recommended Frequency Date Maintenance Performed Check and Clean Filters Every 3 months or if dirty Check Energy Recovery Core Every 6 months Check Drain Pan and Lines Every 3 months • The warranty is limited to 5 years on parts and 7 years on fans from the date of purchase, including parts replaced during this time period.
ERV core washing instructions For proper maintenance of your energy recovery core please follow these instructions 1 3 2 5 4 6 7 8 1 Remove both filters by sliding them out. 2 Remove the core from the unit. 3 With one of your core's air inlets facing down, place it in a large sink, bathtub, or shower. 4 Pour clean tap water through the face of the core facing upwards until it runs clear. Ensure the entire surface is rinsed.
