Installation Instructions For Energy Recovery Ventilator (Fixed)
For Stand Alone Rooftop Application
Energy recovery COMPONENT certified to the ARI Air-toAir Energy Recovery Ventilation Equipment Certification
Program in accordance with ARI Standard 1060-2000.
Actual performance in packaged equipment may vary.
Inspection
Upon receipt of shipment at the job site, carefully check the
shipment against the bill of lading. Make sure all units have
been received. Inspect the carton or crating housing of each
Rooftop Unit and inspect each unit for damage. Assure that
the carrier makes proper notation of any shortages or damage
on all copies of the freight bill and that he completes a Carrier
Inspection Report. Concealed damage not discovered during
unloading must be reported to the carrier within 15 days of
receipt of shipment. NOTE: It is the responsibility of the
purchaser to file all necessary claims with the carrier.
Storage
Upon the arrival of equipment at the job site, immediately store
units in a clean, dry area. Do not stack units. Do not remove
equipment from pallets until equipment is required for
installation.
Unit Protection
Cover rooftop units on the job site. Cap the open ends of pipes.
In areas where painting, plastering, roofing, or the spraying of
fireproof material has not been completed, all due precautions
must be taken to avoid physical damage to the units and
contamination by foreign material. Physical damage and
contamination may prevent proper start-up and may result
in costly equipment cleanup.
Application
Field supplied balancing dampers in duct are recommended.
Recovery Wheel Mode
The Recovery Wheel mode is accomplished by two blowers
providing continuous exhaust of stale indoor air and
replacement by equal amount of outdoor air. Energy recovery
is achieved by slowly rotating the energy recovery wheel within
the cassette frame work. In winter, the ERV adsorbs heat
and moisture from the exhaust air stream during one half of a
complete rotation and gives them back to the cold, drier intake
air supply during the other half rotation. In summer, the process
is automatically reversed. Heat and moisture are absorbed
from incoming fresh air supply and transferred to the exhaust
air stream. This process allows outdoor air ventilation rates
to be increased by factors of three or more without additional
energy penalty or increase in size of heating or air conditioning
systems.

Operation
(How It Works)
The unit contains an Energy Recovery Wheel (ERW)
that is a new concept in rotary air-to-air heat exchangers.
Designed as a packaged unit for ease of installation and
maintenance, only the connection of electrical power is
required to make the system operational.
When slowly rotating through counter flowing exhaust
and fresh air streams the ERW adsorbs sensible heat
and latent heat from the warmer air stream and transfer
this total energy to the cooler air stream during the
second half of its rotating cycle. Rotating at 50-60
revolutions per minute, the wheel provides constant flow
of energy from warmer to cooler air stream. The large
energy transfer surface and laminar flow through the
wheel causes this constant flow of recovered energy
to represent up to 85% of the difference in total energy
contained within the two air streams.
Sensible and latent heat are the two components of total
heat. Sensible heat is energy contained in dry air and
latent heat is the energy contained within the moisture
of the air. The latent heat load from the outdoor fresh air
on an air conditioning system can often be two to three
times that of the sensible heat load and in the winter it is
a significant part of a humidification heat load.
During both the summer and winter, the ERW transfers
moisture entirely in the vapor phase. This eliminates wet
surfaces that retain dust and promote fungal growth as
well as the need for a condensate pan and drain to carry
water.
Pressure Sensor
Measurement device on the ERV to determine airflow
across the Enthalpy Wheel.
Low Ambient Control Kit
Prevents frost formation on energy wheel heat transfer
surfaces by terminating the intake blower operation when
discharge air temperature falls below a field selectable
temperature setting. Intake blower operation resumes
operation after temperature rises above the adjustable
temperature differential.
The frost threshold is the outdoor temperature at which
frost will begin to form on the ERV wheel. For Energy
Recovery Ventilators, the frost threshold is typically below
10ºF. Frost threshold is dependent on indoor temperature
and humidify. The table shows how the frost threshold
temperatures vary depending on indoor conditions.

INDOOR RH AT 70ºF
FROST THRESHOLD
TEMPERATURE
20%
0ºF
30%
5ºF

10ºF
Because Energy Recovery Ventilators have a low frost
threshold, frost control options are not necessary in many
climates. Where outdoor temperatures may drop below
the frost threshold during the ERV operational hours,
exhaust only frost control option is available.
Low Ambient Kit is appropriate for climates with limited
HVAC system operation when outdoor temperatures are
below 10ºF.
Because it is constantly rotating when in the air stream,
the ERV is always being cleaned by air, first in one
direction then the other. Because it is always dry, dust or
other particles impinging on the surface during one half
cycle, are readily removed during the next half cycle.
Stop-Start-Jog
Control option that allows intermittent operation of the
enthalpy wheel during mild outdoor conditions to provide
cycling and cleaning of the wheel.
During the heating season, when outdoor air
temperatures are below 15ºF, it is recommended to use
the (optional) low ambient kit (field installed).
Motorized Exhaust Damper
Damper mounts inside the exhaust air hood. It opens
when the ERV is energized and closes when
de-energized. Powered by B31 damper motor.

THE SMART SOLUTION FOR ENERGY EFFICIENCY
D (ERV) Series
R e v. : 0 4 A p r i l , 2 0 1 4
Rotation Sensor
The circuit indicates the absence of pulses, within a
specified time range, provided by a magnetic sensor
detecting a magnet mounted on wheel surface.
After the initial time delay of approximately 5 seconds
from circuit power up, if the sensor fails to provide a
signal pulse (no wheel rotation) within approximately 5
additional seconds, the alarm relay will activate and latch
(until circuit powers down) providing a 5 amp contact
closure output.
This would indicate no wheel rotation and/or magnet in
the system has stopped at the magnetic sensor pickup
point. If the pulse (wheel rotation) is detected within the
approximately 5 second time period, the alarm relay will
remain open. No field timing adjustment of any type will
be required.
Dirty Filter Switches
Provides indication (red light) of switch closure (field
adjustable set point) when differential pressure across
the filter bank has increase to trip when 24 VAC is
applied to terminals.
Recovery Wheel Mode
On a thermostat call for blower operation in heating,
cooling or continuous blower, the ERW will rotate
between fresh air and exhaust air streams. Both the
fresh air and exhaust air blowers will also be operating to
overcome the air resistance of the ERV.
c. Reapply power.
5. Verify that both blower motors are operating under
their full load AMP rating (FLA). The FLA can be
found on each motor and the unit nameplate.
A. Return Damper Settings
(When tied into HVAC System)
Manually adjust position of field installed dampers to
balance air flow.
B. Air Flow / Blower Speed Adjustment
Blower speed selection is accomplished by changing
the sheave setting on both fresh air and exhaust air
blowers. To set ERV for the required air flow (CFM),
the external static pressure applied to the ERV (duct
static) must be known. See the CFM vs External
Static Pressure chart for the appropriate unit to
determine the correct blower RPM for the specified
CFM and External Static Pressure.
After blower speed adjustments have been made. Ensure
that when the belt is replaced it is tensioned correctly.
The motor mounting plate can be adjusted to tension the
belt. If using a belt tension checker, adjust the span to the
appropriate setting and check the belt defection force.
The belt deflection force should be between 5-8 lbs or the
lowest tension at which the belt will not slip under peak
load conditions.
1. Disconnect main power to unit before making
adjustment to economizer and/or ERV unit.
2. Replace ERV control access cover.
3. Set thermostat to normal operating position.
System Check
1. Disconnect main power.
4. Restore power to unit.
2. Turn to “Cont” for blower operation on thermostat
controlled models.
3. Restore power to unit. Observe ERV wheel rotation
and both fresh air and exhaust air blowers will
operating.
NOTE: If Low ambient kit is used the jumper
between TB37-5 & TB37-6 should be removed.
Also if system check out is being conducted at
low ambient temperatures, technician should
be aware that this kit can cause system not to
operate.
4. Verify that the ERV (3) three phase blower motors
are phased sequentially ensuring correct rotation and
operation.
a. Disconnect power.
b. Reverse any two field power leads to the ERV.
Maintenance
1. All motors use pre-lubricated sealed bearings; no
further lubrication is necessary.
2. Make visual inspection of motors, belts and wheel
rotating bearings during routine maintenance.
3. Eight pie-shaped segments, are seated on stops
between the segment retainer which pivots on the
wheel rim and secured to the hub and rim of wheel.
Annual inspection of the self cleaning wheel is
recommended. With power disconnected, remove
ERV access panels (rear) and unplug [J150 & P150]
(Refer to wiring diagram in this instruction
manual). Remove segment and wash with water and/
or mild detergent.
4. To install wheel segments follow steps A through
E . See Figure 2. Reverse procedure for segment

insert the nose of the segment between the hub
plates.
C. Holding segment by the two outer corners, press
the segment towards the center of the wheel
and inwards against the spoke flanges. If hand
pressure does not fully seat the segment, insert
the flat tip of a screwdriver between the wheel
rim and outer corners of the segment and apply
downward force while guiding the segment into
place.
D. Close and latch each segment retainer under
segment retaining catch.
E. Slowly rotate the wheel 180º. Install the second
segment opposite the first for counterbalance.
Rotate the two installed segments 90º to balance
the wheel while the third segment is installed.
Rotate the wheel 180º again to install the fourth
segment opposite the third. Repeat this sequence
with the remaining four segments.
