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).

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.
CAUTION
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--in. (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.
!
WARNING
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.
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
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.
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
reducepressure 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--in. (457mm) of flexible
duct at ERV/HRV ports for fresh--air supply, and stale--air return.
ERV / HRV
When 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
To connect condensate drain, proceed as follows:
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--in. / 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.

Fig. 8 -- Flexible Duct Fit--Up
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--in.
(457mm) from ground and at least 12--in. (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.

Operation
The Standard and Latent wall controls have 4 basic modes of
operation, OFF, LOW, HIGH, and INTERMITTENT. Be sure that
all modes of operation are fully functional. See Table 1 indicating
standard control operation.
1. With switch off, ERV/HRV is inoperative and the LED is
out.
2. With switch on LOW, ERV/HRV continuously exchanges
air with outside. If control is satisfied, blower will run in
low speed, otherwise, blower will run on high speed. The
LED is illuminated all the time.
3. With switch on INTERMITTENT, the ERV/HRV exchanges air with outside on high--speed blower, and unit
shuts down when control is satisfied. The ON LED is illuminated all the time, and AIR EXCHANGE LED is illuminated only when unit is running.
Humidity Selector
The humidity selector is a built--in control designed to properly
control the level of humidity in the house during the winter and
summer months. This control helps avoid condensation problems
in upper northern regions where indoor humidity is a problem
during the winter season.
NOTE: This control is not to be confused with a dehumidistat
used during the summer months to control high relative indoor
humidity.
Table 2 recommends humidity levels to avoid condensation.
