V - Ap pli ca tion

These Energy Recovery Ventilators (ERV) are used in a down discharge manner equipped with field provided
balancing damper assembly through the roof. 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 era 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

FROST THRESH OLD

TEM PERA 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.

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.

5- Disconnect main power to unit before making adjustment to economizer and/or ERV unit.

6- Replace ERV control access cover.

7- Set thermostat to normal operating position.

8- Restore power to unit.

X - Maintenance

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.
