GENERAL SAFETY INFORMATION
When using electrical appliances, basic precautions should always be followed to reduce
the risk of fire, electric shock and injury to person, including the following:
WARNING:
TO REDUCE THE RISK OF FIRE, ELECTRIC
SHOCK AND INJURY TO PERSON, OBSERVE THE FOLLOWING:
a) Use this unit only in the manner intended by the manufacturer. If you have questions,
contact the manufacturer.
b) Before servicing or cleaning the unit, disconnect the power cord from the electrical outlet.
c) ONLY qualified persons should attempt repair or service of any electrical/internal
component of this product.
WARNING:
TO REDUCE THE RISK OF FIRE, REMOVE ANY SHIPPING
MATERIAL THAT MAY BE PRESENT INSIDE THE UNIT.
c) The cover to this unit is removable to ensure ease of access to internal components during
cleaning and servicing. USE CAUTION when opening or removing the cover of the unit to
avoid risk of personal injury or damage to the cover.
d) Installation work and electrical wiring must be done by qualified person(s) in accordance
with all applicable codes and standards, including fire-related construction.
e) Sufficient air is needed for proper combustion and exhausting of gases through the flue
(chimney) of fuel burning equipment to prevent back drafting. Follow the heating equipment
manufacturer’s guideline and safety standards such as those published by the National Fire
Protection Association (NFPA) and the American Society for Heating, Refrigeration, and Air
Conditioning Engineers (ASHRAE), and the local code authorities.
f) When cutting or drilling into wall or ceiling, do not damage electrical wiring and other
hidden utilities.
CAUTION:
FOR GENERAL VENTILATING USE ONLY. DO NOT USE
TO EXHAUST HAZARDOUS OR EXPLOSIVE MATERIALS AND VAPORS.
g) Ducted fans must always be vented to the outdoors. Do not intake/exhaust into or from
between walls, ceilings, attics, crawl spaces or garages.
h) Do not run any air ducts directly above or closer than 2 ft to any furnace or its supply plenum,
boiler, or other heat producing appliance. If a duct has to be connected to the furnace return
plenum, it must be connected not closer than 9' 10" from this plenum connection to the
furnace (applies only in regions where the outside temperature falls below 32° F).
i) This unit must be grounded. The power cord is equipped with a three-prong grounded
plug that must be inserted into a matching receptacle. Under no circumstances should the
ground prong be cut off the plug. Where a two-prong wall receptacle is encountered, it
must be replaced with a properly grounded three-prong receptacle installed in accordance
with the National Electrical Code (NEC) and all applicable local codes and ordinances. This
work must be done by a qualified electrician, using copper wires only.
j) To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray,
construction dust, etc. off power unit. Turn unit OFF during construction or renovations.
k) Read all instructions before installing or using exhaust fan.
l) For residential installations only.
m) Must use suitable weather hood with insect screen to protect air intake.
n) DO NOT install this product in an unconditioned space—61º F ambient temperature is
recommended—or in a space/manner where maintenance and service might pose a risk of
personal injury or damage to this product.
o) If ductwork passes through unconditioned spaces, it must be insulated.
WARNING:
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, DO
NOT USE THIS FAN WITH ANY SOLID-STATE SPEED CONTROL DEVICE.
p) This unit is not designed to provide combustion and/or dilution air for fuel-burning appliances.
q) Due to the weight of the unit, two installers are recommended to perform installation.
WARNING:
DO NOT USE IN KITCHENS.
WARNING:
FOR INDOOR INSTALLATIONS ONLY.
WARNING:
THE DUCTING FROM THIS FAN TO THE OUTSIDE OF THE
BUILDING HAS A STRONG EFFECT ON THE AIR FLOW, NOISE AND ENERGY USE OF THE
FAN. USE THE SHORTEST, STRAIGHTEST DUCT ROUTING POSSIBLE FOR BEST PERFORMANCE,
AND AVOID INSTALLING THE FAN WITH SMALLER DUCTS THAN RECOMMENDED. INSULATION
AROUND THE DUCTS CAN REDUCE ENERGY LOSS AND INHIBIT MOLD GROWTH. FANS
INSTALLED WITH EXISTING DUCTS MAY NOT ACHIEVE THEIR RATED AIRFLOW.
INSTALLATION CONSIDERATIONS:
Prior to integrating this ERV/HRV with any other piece of mechanical equipment, i.e. furnace, air handler, combustion heating appliance, careful consideration must be given to system design and
integration to ensure compatibility and proper operation of both appliances. Do not connect the duct system of your ERV/HRV to any clothes dryer or kitchen exhaust fan duct system.
Whether installing this ERV/HRV as part of an independent system or to integrate it with a central heating/cooling system, use the procedure in this manual to ensure that the air flows of the ERV/HRV are
balanced. Only a properly balanced ERV/HRV will deliver maximum performance and energy efficiency.
Although this document contains guidelines for proper ERV/HRV sizing and installation, your ventilation system should be installed in conformance to the appropriate local or state building
regulations or National Building Code and/or ASHRAE “Good Engineering Practices”.
