equipment, observe precautions in the literature, on tags, and on
labels attached to or shipped with the unit and other safety
precautions that may apply.
Follow all safety codes. Installation must be in compliance with
local and national building codes. Wear safety glasses, protective
clothing, and work gloves. Have fire extinguisher available. Read
these instructions thoroughly and follow all warnings or cautions
included in literature and attached to the unit.
Recognize safety information. This is the safety--alert symbol
When you see this symbol on the unit and in instructions or
manuals, be alert to the potential for personal injury.
Understand these signal wo rds; 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.
INSTALLATION CONSIDERATIONS
Inspect Equipment
Move carton to final installation location. Remove ERV/HRV from
carton taking care not to damage unit. Remove all packaging and
inspect unit for damage. Remove parts bag from inside unit. File
claim with shipping company if shipment is damaged or
incomplete. Check to make sure ERV/HRV unit matches Fig. 1 or
Fig. 2.
Select Location
The ERV/HRV should be located in a conditioned space and in
close proximity to a fused power source. It should be easily
accessible for routine maintenance.
If ERV/HRV is installed independent of a forced--air system, unit
should be located near the center of the air distribution system. If
ERV/HRV is installed in conjunction with a forced--air system, unit
ERV / HRV
should be located next to (or close to) the indoor equipment.
COMPONENT DESCRIPTION
The following listed items are components o f ERVBBSHA (See
Fig. 4).
1. Exhaust--air connected to outdoor air exhaust hood.
2. Fresh--air intake connected to outdoor air inlet hood.
3. Fresh--air supply from ERV connected to return--air duct of

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.
Mount Unit
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.) The unit may be installed on a shelf if an isolation pad
is provided to dampen vibration. Unit should always be installed as
level as possible.

WARNING
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal injury
or death.
Do not install return--air registers (or stale--air pickup registers)
in same room as gas furnace or water heater.
A05331
Fig. 6 -- Chain Spring Installation
Independent System Application
In the absence of a forced--air system and a typical duct system
layout, the ERV/HRV can be applied as an independent or stand
alone unit. To ensure comfort, this type of application involves
running both fresh--air and return--air registers (or stale--air pickup
registers) throughout the home.
Fresh--air registers are normally located in bedrooms, dining room,
living room, and basement. It is recommended that registers be
placed 6 to 12” (152 to 305mm) from the ceiling on an interior
wall and airflow directed toward ceiling. If registers are floor
installed, airflow should be directed toward the wall.
Return--air (or stale--air pickup registers) are normally located to
draw from kitchen, bathroom, basement, or other rooms where
stale--air can exist.
Proper size and type of registers must be used to minimize pressure
drop. The velocity of airflow through register should not be above
400 ft (122m) per minute.
Maximum length of duct for the system should be designed
according to the highest speed of the unit. Refer to specifications
listed in unit Product Data Digest for ventilation capacities.
Forced--Air Application
Most ERV/HRV applications will be installed in conjunction with
new or existing forced--air system. To operate properly, the
fresh--air supply and stale--air return from ERV/HRV connect
directly to return--air duct system. This is how the ERV/HRV
distributes fresh air and removes stale air from inside of building
(See Fig. 7). For these installations, furnace or fan coil blower must
be interlocked and operate continuously whenever ERV/HRV is
energized. See Fig. 17 for interlock wiring detail.
NOTE: The fresh air from ERV/HRV is introduced into return--air
duct at a point no less than 6 ft (1.8m) upstream of furnace or fan
coil. This connection should be direct (See Fig. 7). This is to allow
incoming fresh --air to mix before entering indoor equipment.

PROPERTY DAMAGE HAZARD
Failure to follow this caution may result in minor property
damage from sweating duct or loss of unit efficiency and
capacity.
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. When
using insulated flexible duct, the vapor barrier of the flexible ducts
must be taped very tight to prevent condensation problems. To
reduce pressure drop, stretch the flex duct and support it in a proper
manner to avoid reduced airflow.
When connecting the ERV/HRV to a return--air duct system,
insulated flexible duct can be used. However, when metal or rigid
ducts are applied use approximately 18” (457mm) of flexible duct
at ERV/HRV ports for fresh--air supply, and stale--air return. When
ERV / HRV
using metal duct from fresh--air supply to system duct work, the
metal duct should be insulated. (See Fig. 8.) This can act as a
silencer when connecting ducts to return--air duct system. This
should eliminate transmission of noise or vibration from unit to
main duct system.
CAUTION
1. Punch out holes in foam insulation and door, then insert
sleeved grommets into bottom of unit using the gasket
washer and nut. (See Fig. 9.)
2. Cut two sections of plastic tubing, about 12” / 305mm long
and attach them to each drain.
3. Join the two short sections of plastic tubing to the “T” connector and the main tube as shown.
4. Make a loop in the tubing below the “T” connector to create
a trap to prevent sewer gases from entering the ventilation
system. (See Fig. 9.)
5. Connect unit drain to building’s main drain. Provide slight
slope from unit for run --off.

Locate and Install Exterior Hoods
IMPORTANT: To prevent condensation problems, insulated
flexible ducts are required on both fresh--air inlet and exhaust--air
outlet ducts connecting between ERV/HRV and exterior wall.
Fresh--air intake and stale--air exhaust must be separated by at least
6 ft (1.8m). Fresh--air intake must be positioned at least 10 ft (3m)
from nearest dryer vent, furnace exhaust, driveway, gas meter, or
oil fill pipe. Fresh--air intake must be positioned as far as possible
from garbage containers and potential chemical fumes. When
possible, it is advised to locate the intake and exhaust hoods on
same side of house or building. The intake and exhaust hoods
should never be located on interior corners or in dead air pockets
(See Fig. 7). Both intake and exhaust hoods must be 18” (457mm)
from ground and at least 12” (305mm) above anticipated snow
level.
After selecting proper hood locations, make appropriate size hole
through exterior wall, pass flexible duct through hole and insert
hood tube into duct. Tape duct vapor barrier tightly around hood
tube and insert assembly back into wall and fasten securely.
