Energy recovery COMPONENT certi

ed to the ARI Air-to-

Air Energy Recovery Ventilation Equipment Certi

cation

Program in accordance with ARI Standard 1060-2000.
Actual performance in packaged equipment may vary.

ETL Certi

ed per UL 1995 and CSA 22.2

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

le 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, roo

ng, or the spraying of

reproof 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.

Rigging Unit For Lifting

1. Maximum weight 300-1200 lbs. See Physical Data Table.
2. Remove crating.
3. All panels must be in place for rigging.

external static pressure and air

ow (CFM) requirements. If

blower speed is not adjusted for conditions, possible motor
over loading can occur.

8. Ground unit with a suitable ground connection either

through unit supply wiring or an earth ground.

NOTE: Unit voltage entries must be sealed

weather tight after wiring is complete.

9. Remove motor access panels. Locate belts fastened

to blower assembly. Install belt onto motor and blower
pulley. Adjust motor sheave to correct blower RPM for
CFM and external static pressure requirements. See
charts in this instruction. Multiple pulley arrangements
are available to meet the entire range.

10. Replace access panel onto the ERV unit and secure.
11. Restore power to unit.
12. Cleanup once unit is operating properly, caulk

any open joints, holes or seams to make the units
completely air and water tight.

13. Leave this instruction manual with owner or in an

envelope to be kept near unit.

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

owing 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

of energy from warmer to cooler air stream. The large
energy transfer surface and laminar

ow through the

wheel causes this constant

ow 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

C L I M A T E M A S T E R W A T E R - S O U R C E H E A T P U M P S

C l i m a t e M a s t e r Wa t e r - S o u r c e H e a t P u m p s

times that of the sensible heat load and in the winter it is
a signi

cant part of a humidi

cation 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,

rst 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 (

eld 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.

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 (Optional)

Low Ambient Kit turns off the supply blower when outdoor
temperatures fall below the frost threshold. The exhaust
only thermostat set points are

eld 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.

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.

System 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 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

eld 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. Return Damper Settings

Manually adjust position of

eld installed dampers to

balance air

ow.

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

ow (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 speci

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 de

ection 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.

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 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

anges. If hand

pressure does not fully seat the segment, insert
the

at 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

rst 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.

Pulley Kit Installation

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

xed pitch pulley then

remove belt and both motor and blower pulley

b. An adjustable sheave then remove the motor

pulley.

c. A

xed pitch pulley then remove the blower pulley.

2. Replace pulley(s) with the pulley(s) from pulley kit.
