ANSI/NFPA No. 70.

V - Ap pli ca tion

These Energy Recovery Ventilators (ERV) are used in a
horizontal discharge manner equipped with field
provided balancing damper assembly in the horizontal
duct work. A roof curb must be provided to Rooftop
Systems specifications. These wheels conserve energy by
mixing warmer air with cooler air in the following manner:

Re cov ery 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.

VIII - Op er a tion
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 transfers 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.

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.

During the heating season, when outdoor air temperatures
are below 15oF, it is recommended to use the (optional)
low ambient kit (field installed).

Low Ambient Kit is appropriate for climates with limited
HVAC system operation when outdoor temperatures are
below 10oF.

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

20% 0oF
30% 5oF
40% 10oF

FROST THRESH OLD

TEM PER A TURE

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 Am bi ent Kit (Op tional)

Low Ambient Kit turns off the supply blower when outdoor
temperatures fall below the frost threshold. The exhaust
only thermostat set points are field adjustable. Supply fan
operation is automatically restored when the exhaust air
temperature rises above the thermostat set point.
Provisions for introducing make-up air into the building
when the supply blower is off to avoid depressurization
should be considered.

Re cov ery 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.

IX - Sys tem Check

1. Disconnect main power.

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 while
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.

PAGE 2

a - Disconnect power.

b - Reverse any two field power leads to 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 - Re turn Damper Set tings

Manually adjust position of field installed dampers to
balance air flow.

B - Air Flow / Blower Speed Ad just ment

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.

4. Restore power to unit.

X - Main te nance

1. All motors use prelubricated 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 is secured to the hub and rim of the
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 1. Reverse procedure for segment
removal.

a. Unlock two segment retainers (one on each side of

the selected segment opening.

b. With the embedded stiffener facing the motor side,

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 screw driver 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.

XI - Pul ley Kit In stal la tion

The units are shipped from the factory at the low static
setting. Pulley kits are available for the medium and high
static settings. To install a pulley kit.

1. Check content of pulley kit, if pulley kit contains:

a. An adjustable sheave and a fixed pitch pulley then

remove belt and both motor and blower pulley

b. An adjustable sheave then remove the motor

pulley.

c. A fixed pitch pulley then remove the blower pulley.

2. Replace pulley(s) with the pulley(s) from pulley kit.
Make sure each pulley is installed with a key. Tighten
the set screw on the pulley(s) to 100 in.lb.

3. Install the belt that came with the pulley kit. Tension
belt as explained in the blower speed adjustment
section.

4. Check the speed of the blower. Adjust the motor
sheave to increase or decrease the speed of the
blower. See blower adjustment section.
