Excessive negative pressure may also cause the backdrafting of vented combustion equipment. Read the Application Warning on the front of this manual! Prior to balancing, ensure that: 1. All sealing of the ductwork system has been completed. 2. All of the HRV/ERV's components are in place and functioning properly. 3. Balancing dampers are fully open. 4. Unit is on HIGH speed. 5. Air flows in branch lines to specific areas of the house should be adjusted first prior to balancing the unit. A smoke

During the air conditioning season, the HRV will help cool the incoming fresh air with the cooler stale exhausting air. RNC Electronics RNC electronics offers standard 2-speed operation of low/high. There is also an installer selectable 2-speed operation of medium low/high (refer to "Increasing Low Speed to Medium Low" in this manual). The RNC circuit board also includes an interlock relay which is used to Interlock the HRV to an Air Handler/Furnace. Refer to "Interlocking HRV Operation to an Ai

During the winter months, the incoming cold fresh air is warmed by utilizing the heat recovered from the stale air before it is exhausted to the outdoors. During the summer months, the cool outgoing stale air from the air conditioned dwelling is used to help cool the incoming fresh air. Your HRV features the digital electronic BASE MODULE that uses a microprocessor to control fan speed and unit operation. Both digital (3 wire) and standard (2 wire) remote devices can control the HRV when conne

Furnace blower may be required to operate when ventilation from HRV/ERV is required. The furnace should be set to run continuously or interlocked with HRV/ERV. 2. A minimum separation of 40 inches (1 m) is required between the two direct connections. 3. The

Due to numerous applications in which this equipment can be installed, it is difficult to predict servicing intervals. In certain situations where there is heavy smoke, servicing the equipment every one two months may be needed; whereas ventilating a meeting room for example for carbon dioxide may only need service every six months to a year. Motor Access to the motor is through the front service doors. Note heat exchanger core can be removed to provide more room. See CORE in this section. The m

The HRV cabinet has prepunched holes for the drain (see below). Insert the drain spout through the hole in the drain pan. Do not forget the “O ring” which seals each spout to the pan REMEMBER TO HAND TIGHTEN ONLY the washer and lock nut which hold the drain spout in place. Construct a P-Trap using the plastic tee connector. Cut two lengths of hose and connect each piece to an end of the “T” fitting, then connect the other ends to the two drain spouts. Position the “T” fitting to point upward and
