INSTALLATION INSTRUCTIONS
CAUTION:
MAKE SURE UNIT IS UNPLUGGED BEFORE STARTING
INSTALLATION.
WARNING:
TO REDUCE THE RISK OF FIRE, REMOVE ANY
SHIPPING MATERIAL THAT MAY BE PRESENT INSIDE THE UNIT.
SECTION 1
Preparing the Installation Area
CAUTION:
INSTALLERS ARE RESPONSIBLE FOR THE PERFORMANCE
OF THE VENTILATION SYSTEM AND FOR ENSURING THAT ALL CODES AND
STANDARDS ARE MET.
1. Ensure that all the following conditions are met:
a) Do not mount the fresh air supply near a source of contaminated air such as
automotive exhaust, gas or propane exhaust, garbage containers or oil tanks.
b) Do not connect a dryer exhaust to an ERV/HRV.
c) Combustion appliances such as furnaces and water heaters must not draw
combustion air directly from an ERV/HRV.
d) Do not connect a kitchen range hood to any part of this system.
e) Do not install in attics or other unconditioned spaces (min. 61º F).
f) Do not install in enclosed garages.
g) Maintain straight duct runs as much as possible, using as few joint fittings as possible.
h) Keep use of flexible ducting to a minimum.
i) Be sure to observe local codes regarding running and insulating ducts in
unconditioned spaces.
j) Poorly insulated ducts run in unconditioned spaces will hamper the efficiency of the unit.
SECTION 2
Installation Options
CAUTION:
INTERCONNECTION WITH A FORCED AIR FURNACE DUCT
SYSTEM IS PERMISSIBLE; HOWEVER, YOUR ERV/HRV IS NOT INTENDED TO BE
CONNECTED TO ANY OTHER EQUIPMENT OR APPLIANCES.
NOTE:
When selecting an installation option, consideration should be given to the increased
electrical consumption of the furnace fan. The way your ERV/HRV is installed may make a
significant difference to the electrical energy used. To minimize the electricity use of the
ERV/HRV, a stand-alone fully ducted installation is recommended. If you choose a simplified
installation that operates your furnace air handler for room-to-room ventilation, an electrically
efficient furnace that has an electronically commutated (EC) variable speed blower motor will
minimize your electrical energy consumption and operating cost. Installing a user-accessible
control with your product will improve comfort and may significantly reduce the product’s
energy use. Most building codes require a centrally located control with an on/off switch.
Fully Ducted System
1. This system uses an
independent duct system for
supply and exhaust air. The ERV/
HRV is controlled independently
of all other equipment. The best
results are achieved when:
• Each room of the space
is serviced with a vent
mounted in the ceiling or
high on an interior wall
(within 12" of the ceiling).
• Vents are located deep
within a room, where they
will not short circuit or
create an uncomfortable draft.
Extended Exhaust System
1. This system uses the ERV/HRV in conjunction with a forced air furnace distribution
system. In this system the ERV/HRV supply air to the house is introduced into the return
duct of the forced air furnace. Separate
ductwork (not included) is used to transfer
stale air from the wet rooms to the ERV/HRV.
2.
Extended System, Continuous Ventilation:
The furnace fan may not need to run
continuously with this system. Check local code requirements. For improved supply air
distribution during continuous ventilation mode, the furnace may be interlocked to the ERV/
HRV. See Section 7 for interlock wiring and settings and Section 10 Control Wiring and Options.
3.
Extended System, Intermittent Ventilation:
If the ERV/HRV is operated intermittently,
the furnace fan should be interlocked with the ERV/HRV for good distribution of supply air
during high-speed ventilation conditions.
Simplified System
1. This system uses the furnace’s return plenum for both supply air distribution and exhaust
air collection. The exhaust air connection must be a minimum of 40 inches upstream of
the supply air connection to avoid short circuiting of the fresh air.
2.
Simplified System, Continuous Ventilation & Intermittent Operation:
For proper
supply air distribution with this system, and to prevent short circuiting in the return air
duct, the furnace fan must run during ventilation mode. Interlock the furnace and unit in
accordance with Section 7.
SECTION 3
Preparing the Unit
1. Unpack unit from the carton and confirm that all pieces are present. In addition to the unit
you should have:
Standard Filters
Anti-Vibration Straps
Removable Terminal Block
8 - Washers
4 - ½ Screws
Drain Hose Assembly (HRV ONLY)
Core
RVC8 Control Switch
Instruction/Safety Sheet
2.
Choose the location for your unit. To ensure the best air and sound performance, it is
recommended that the length of ducting and the number of elbows be kept to a minimum,
the radius of each elbow be as large as possible for the installation, and that insulated hard
ducting be used. The unit is designed to mount from the ceiling using the included anti-
vibration mounting straps. Avoid mounting the unit under bedrooms or other quiet areas.
NOTE:
The unit must be installed into a location that can be easily accessed once installed.
3.
No additional vibration deadening materials are needed for this fan.
SECTION 4
Mounting the Fan
1. Using appropiate sized mounting screws at
least #8 x 1.5" (not included) insert through
the included washers and hanging strap
grommets, then fasten to the mounting
surface. If mounting to a material other than
a wood joist use an appropriate mounting
method as determined by a professional.
2. Insert the included screws through the washers
and bottom grommets of the straps, then
fasten to the unit.
3. Pull down vertically on each strap while lifting
the bottom of the unit. Level the unit from right
to left and front to back.
4. To loosen strap, lift up on the buckle.
NOTE:
Support unit and gently lift as you tighten each strap.
