GENERAL SAFETY INFORMATION For Your Safety To reduce the risk of injury, loss of life, electric shock, fire, malfunction, and damage to equipment or property, always observe the following safety precautions. Explanation of symbol word panels The following symbol word panels are used to classify and describe the level of hazard, injury, and property damage caused when the denotation is disregarded and improper use is performed. A WwW.
GENERAL SAFETY INFORMATION 0 The special-purpose or dedicated parts, such as mounting fixtures, must be used if such parts are provided and appropriate. Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent back drafting.
DESCRIPTION The Panasonic Energy Recovery Ventilator (ERV) uses 2 sirocco fans driven by 2 DC motors. The motor is designed to have an extended service life with reduced energy consumption. The ERV also incorporates a thermal-cutoff for safety. The exhaust air (EA) and outdoor air {OA) ducts include electric dampers to prevent back drafting. Energy Recovery Introduction: Compared to an HRV (Heat Recovery Ventilator), the ERV can also transfer humidity and recover energy from that humidity.

START-UP PROCEDURE 1.Fill in beginning time on the OA filter before starting up the unit. The method of removing and installing OA filter please refer to P.20 (Fig.20) and P.21 OA filter BEGINNING TIME: BX 2.Connect the power cord to outlet then turn on the main switch on ERV for start-up. If the ERV does not run, please check the wiring connections. 3.Remove plug covers in plugs on frame and check static pressure.
OPERATION ® Filter indicator: The indicator light will turn on when the ERV accumulated run time equals 3 months. When the indicator is on (with buzzer sound), RA and OA filter maintenance should be performed. (1) The indicator will turn on when the product accumulated run time reaches 90 days. The buzzer sound will occur every hour for 10 seconds. (2)To turn off the buzzer indicator, press filter reset button for about 10 seconds until you hear a long beep.
OPERATION This product is designed to operate in outdoor temperature ranges from -22 °F (-30 °C)~ 104 °F (40 °C). In cold temperature below 14 °F (-10 °C), product will automatically be operated in defrost mode, which consists of an alternating heat exchange / circulation operation. During defrost mode, the OA damper closes and the center bypass damper opens. This allows indoor air to be recirculated during the defrost cycle only. EA damper open Outside air (OA) = OA damper.
MAINTENANCE A CAUTION Electric shock may result. Disconnect power by switching off main switch first, then unplug the power plug before working on unit when it is in default mode. Electric shock may result. Disconnect power by switching off wall switch first, then 0 main switch and unplug the power plug before working on unit when replacing the jumper cable with wall switch.
MAINTENANCE 4 Reinstall and close frame cover by locking the latches. (Fig.22) 5.After re-connecting power, press the filter reset button about 3 seconds to reset run timer. (Fig.
