SAFETY CONSIDERATIONS

Improper installation, adjustment, alteration, service, maintenance,

or use can cause explosion, fire, electrical shock, or other

conditions which may cause death, personal injury or property

damage. Consult a qualified installer, service agency, or your

distributor or branch for information or assistance. The qualified

installer or agency must use factory--authorized kits or accessories

when modifying this product. Refer to the individual instructions

packaged with kits or accessories when installing.

Follow all safety codes. Wear safety glasses, protective clothing

and work gloves. Have a fire extinguisher available. Read these

instructions thoroughly and follow all warnings or cautions

included in literature and attached to the unit. Consult local

building codes and the current editions of the National Electrical

Code (NEC) NFPA 70.

In Canada, refer to the current editions of the Canadian Electrical

Code CSA C22.1.

Recognize safety information. This is the safety--alert symbol

When you see this symbol on the unit and in instruction manuals,

be alert to the potential for personal injury.

Understand the signal words DANGER, WARNING,and

CAUTION. These words are used with the safety--alert symbol.

DANGER identifies the most serious hazards which will result in

severe personal injury or death. WARNING signifies hazards

which could result in personal injury or death. CAUTION is used

to identify unsafe practices which may result in minor personal

injury or product and property damage. NOTE is used to highlight

suggestions which will result in enhanced installation, reliability, or

operation.

INTRODUCTION

The Energy/Heat Recovery Ventilator (ERV/HRV) is used to

exchange indoor stale air with outside fresh air. The unit is

equipped with a special energy/heat recovery core which transfers

both sensible and/or latent heat between the fresh incoming air and

stale exhaust air. The cross--flow design core allows entering and

leaving air streams to transfer heat and/or latent energy without

mixing (See Fig. 3).

The model operates at 2 airflows, 50 CFM in low speed and 100 CFM in high speed. This unit comes in two configurations, vertical or horizontal. Special attention should be given to duct application, balancing the ERV/HRV, and locating unit for easy access and routine maintenance. 4. Mechanical filters trap dust contained in the air. 5. Energy recovery core is a cross--flow type. The core transfers heat between the 2 air streams. 6. Blowers bring in fresh--air from outside and exhaust stale-air to outside.

UNIT INSTALLATION CAUTION UNIT DAMAGE HAZARD Failure to follow this caution may result in equipment damage or improper operation. Do not install ERV/HRV in a corrosive or contaminated atmosphere. ! WARNING CARBON MONOXIDE POISONING HAZARD Mount Unit Failure to follow this warning could result in personal injury or death. The ERV/HRV can be suspended from floor joists using chains and 4 springs. Attach metal hanging bracket to all 4 sides of cabinet. (See Fig. 6.

Connect Ducts to ERV/HRV ! Condensate Drain CAUTION PROPERTY DAMAGE HAZARD Failure to follow this caution may result in minor property damage from sweating duct or loss of unit efficiency and capacity. ERV / HRV If ERV/HRV duct work is installed in an unconditioned space, insulated flexible duct is required. Insulated flexible duct is required on both fresh--air inlet and exhaust--air outlet ducts connecting to exterior wall.

Wiring OneTouch Control Remove top cover assembly from wall control and pass thermostat wire through hole located on back of control before attaching to wall. Connect Y, R, G, and B (yellow, red, green, and black) between wall control and ERV/HRV connector following color code. (See Fig. 5 and 10.) Replace top cover assembly. NOTE: ERV/HRV wall control and circuit board operate on 12VDC. The OneTouch Control can be used as the primary wall control for the ERV/HRV.

OPERATING THE ERV/HRV WITH THE EVOLUTION CONTROL The ventilator has four settings in heating mode and three settings in cooling mode. Heating: AUTO -- the ventilator selects the speed based on indoor humidity and outdoor temperature. It may cycle on/off every 30 minutes depending on humidity and outside temperature. LOW -- low speed all of the time. HIGH -- high speed all of the time. DEHUM -- will only turn on if humidity is 3% over setpoint.

BALANCING ERV/HRV Balancing intake and exhaust airflow is very important for proper system operation and optimum performance when applying an ERV/HRV. Unit balancing prevents a positive and/or negative pressure within the home. Balancing the ERV/HRV is done by applying magnehelic gauge and using the balancing dampers at the fresh air intake and stale air exhaust ducts. (See Fig. 13.)

VENTILATION EVALUATION between Red and Gray wires on Molex plug (pins 1 and 4) and blower motor runs in low--speed operation. CAUTION ! CARE AND MAINTENANCE Door UNIT DAMAGE HAZARD Failure to follow this caution may result in reduced unit efficiency, capacity or unit life. DO NOT use HRV during construction of a house or when sanding drywall. This type of dust may damage system. Ventilator Sizing ERV / HRV Tables 3 and 4 should be used to determine the required airflow for a home.

! CAUTION UNIT COMPONENT DAMAGE HAZARD Failure to follow this caution may result in equipment damage or improper operation. DO NOT use water to clean core or damage will result. In addition, before servicing or removing the core inspect the edges to see if they appear soft (or slightly expanded). This can be normal and due to moisture in the air. DO NOT handle or service core until it is dry or air passages can become damaged and/or closed.
