SAFETY
1.1 GENERAL
Sullair Corporation and its subsidiaries design and
manufacture all of their products so they can be
operated safely. However, the responsibility for safe
operation rests with those who use and maintain
these products. The following safety precautions are
offered as a guide which, if conscientiously followed,
will minimize the possibility of accidents throughout
the useful life of this equipment.
The compressor should be operated only by those
who have been trained and delegated to do so, and
who have read and understood this Operator's
Manual. Failure to follow the instructions, procedures
and safety precautions in this manual may result in
accidents and injuries. NEVER start the compressor
unless it is safe to do so. DO NOT attempt to operate
the compressor with a known unsafe condition. Tag
the compressor and render it inoperative by
disconnecting and locking out all power at source or
otherwise disabling its prime mover so others who
may not know of the unsafe condition cannot attempt
to operate it until the condition is corrected.
Install, use and operate the compressor only in full
compliance with all pertinent OSHA regulations and/
or any applicable Federal, State, and Local codes,
standards and regulations. DO NOT modify the
compressor and/or controls in any way except with
written factory approval.
While not specifically applicable to all types of
compressors with all types of prime movers, most of
the precautionary statements contained herein are
applicable to most compressors and the concepts
behind these statements are generally applicable to
all compressors.
1.2 PERSONAL PROTECTIVE
EQUIPMENT
A. Prior to installing or operating the compressor,
owners, employers and users should become
familiar with, and comply with, all applicable
OSHA regulations and/or any applicable Federal,
State and Local codes, standards, and regula-
tions relative to personal protective equipment,
such as eye and face protective equipment,
respiratory protective equipment, equipment
intended to protect the extremities, protective
clothing, protective shields and barriers and elec-
trical protective equipment, as well as noise
exposure administrative and/or engineering con-
trols and/or personal hearing protective equip-
ment.
1.3 PRESSURE RELEASE
A. Install an appropriate flow-limiting valve between
the service air outlet and the shut-off (throttle)
valve, either at the compressor or at any other
point along the air line, when an air hose exceed-
ing 1/2" (13mm) inside diameter is to be con-
nected to the shut-off (throttle) valve, to reduce
pressure in case of hose failure, per OSHA Stan-
dard 29 CFR 1926.302(b)(7) and/or any applica-
ble Federal, State and Local codes, standards
and regulations.
B. When the hose is to be used to supply a mani-
fold, install an additional appropriate flow-limiting
valve between the manifold and each air hose
exceeding 1/2" (13mm) inside diameter that is to
be connected to the manifold to reduce pressure
in case of hose failure.
C. Provide an appropriate flow-limiting valve at the
beginning of each additional 75 feet (23m) of
hose in runs of air hose exceeding 1/2" (13mm)

personnel that are trained, qualified and dele-
gated to do so.
B. Keep all parts of the body and any hand-held
tools or other conductive objects away from
exposed live parts of electrical system. Maintain
dry footing, stand on insulating surfaces and DO
NOT contact any other portion of the compressor
when making adjustments or repairs to exposed
live parts of the electrical system. Make all such
adjustments or repairs with one hand only, so as
to minimize the possibility of creating a current
path through the heart.
C. Attempt repairs in clean, dry and well lighted and
ventilated areas only.
D. DO NOT leave the compressor unattended with
open electrical enclosures. If necessary to do so,
then disconnect, lock out and tag all power at

rotating machinery and prior to handling any
ungrounded conductors.
1.9 LIFTING
A. If the compressor is provided with a lifting bail,
then lift by the bail provided. If no bail is provided,
then lift by sling. Compressors to be air-lifted by
helicopter must not be supported by the lifting
bail but by slings instead. In any event, lift and/or
handle only in full compliance with OSHA stan-
dards 29 CFR 1910 subpart N and/or any appli-
cable Federal, State, and Local codes, standards
and regulations.
B. Inspect points of attachment for cracked welds
and for cracked, bent, corroded or otherwise
degraded members and for loose bolts or nuts
prior to lifting.
C. Make sure entire lifting, rigging and supporting
structure has been inspected, is in good condi-
tion and has a rated capacity of at least the

are provided, then make sure compressor is
secure and well balanced on forks before
attempting to raise or transport it any significant
distance.
L. Make sure forklift truck forks are fully engaged
and tipped back prior to lifting or transporting the
compressor.
M. Forklift no higher than necessary to clear obsta-
cles at floor level and transport and corner at
minimum practical speeds.
N. Make sure pallet-mounted compressors are
firmly bolted or otherwise secured to the pallet
prior to attempting to forklift or transport them.
NEVER attempt to forklift a compressor that is
not secured to its pallet, as uneven floors or sud-
den stops may cause the compressor to tumble
off, possibly causing serious injury or property
damage in the process.
1.10 ENTRAPMENT
A. If the compressor enclosure, if any, is large
enough to hold a man and if it is necessary to
enter it to perform service adjustments, inform
other personnel before doing so, or else secure
and tag the access door in the open position to
avoid the possibility of others closing and possi-
bly latching the door with personnel inside.
B. Make sure all personnel are out of compressor
before closing and latching enclosure doors.

EES USER MANUAL
DESCRIPTION
2.1 INTRODUCTION
The Sullair Integral Heat Recovery System is a
means of recovering energy which is expended while
producing compressed air. This energy can be
converted into a useable source of heat. The heat is
stored in the compressor cooling air as it passes over
the compressor motor, fluid cooler and aftercooler.
Latent heat rejected when moisture is condensed
from the compressed air in the aftercooler may also
be recovered. The compressor cooling air may then
be used as preheated makeup air or heating air.
Heat may also be rejected when not required.
Because the heat recovery system is built into the
compressor package it requires a minimal amount of
installation labor. The system has been designed so
that use of auxiliary blowers is not needed as long as
good duct design is practiced.
2.2 APPLICATION
CONSIDERATIONS
GENERAL
The Sullair EES is designed primarily to recover the
heat of compression in the form of heated makeup
air. Maximum energy utilization, minimum cost of
installation, and maximum return on investment will
be realized by using the EES in this manner. For
every cubic foot of outside air brought into a building
by the EES, another cubic foot of air that would have
infiltrated into the building at outside temperature will
be eliminated. The fuel savings result from the
primary heating system of the facility not having to
heat that cubic foot of air at outside temperature to
the temperature of the heated space.
It is possible for the EES system to operate efficiently
as a heating system; that is, where air is drawn and
heated to some higher temperature (say 90°F
[32°C]), then distributed throughout the heated
space. This usually requires greater capital
investment in the form of a larger ductwork system to
distribute the heated air.
As a preheated makeup air system, air is brought in
from the outside at some low temperature (say 40°F
[14°C]), heated approximately to the heated space
temperature (say 65°F [18°C]), and then released to
the heated space at one location. Since the air is
close to heated space temperature, there is little
advantage in distributing this air throughout the plant.
In either case, the same amount of energy is
recovered, but in the makeup air system, significant
reductions in the installed costs are possible.
It is also possible to utilize the waste heat of
compression for process heating applications such
as drying parts. This type of application will usually
net a greater return on investment because the heat
can be used year round.
DANGER
Any makeup air introduced into a heating or
ventilation system by this system must be
of breathing air quality as defined by appli-
cable codes, laws or regulations.

2.3 FUNCTIONAL DESCRIPTION
—MIXED AIR
TEMPERATURE SENSOR
Refer to Figure 2-1. The mixed air temperature
sensor is mounted in the compressor enclosure in
front of the combination cooler. This sensor monitors
the temperature of the mixture of bypass and outdoor
air. Based on this sensor, the proportional controller
(Figure 2-2) will modulate the incoming and bypass
air damper actuator motors to maintain a set
temperature of air into the cooler.
2.4 FUNCTIONAL DESCRIPTION
—OUTSIDE AIR
TEMPERATURE SENSOR
Refer to Figure 2-1. The outdoor air temperature
sensor is mounted in the incoming air stream outside
of the compressor enclosure. This sensor monitors
the temperature of the incoming air. When the
temperature of the incoming air exceeds the set
value on the outside air temperature controller
(Figure 2-2), all heat of compression is rejected
outdoors. In addition, the incoming air damper is
fully opened and the bypass air damper fully closed.

2.5 FUNCTIONAL DESCRIPTION
—ROOM THERMOSTAT
The room thermostat monitors the temperature of the
heated space. If the temperature of the heated
space exceeds the set value, all heat of compression
is rejected outdoors.
2.6 FUNCTIONAL DESCRIPTION
—INCOMING AND BYPASS
AIR DAMPERS AND
ACTUATORS
Refer to Figure 2-1. The incoming and bypass air
dampers modulate to maintain a set mixed air
temperature into the combination cooler. Based on
the mixed air sensor value, a proportional controller
(Figure 2-2) sends a variable 0-10VDC control signal
to a proportional actuator direct mounted to each
damper shaft. Each damper operates from the same
control signal but in opposite directions, i.e. the
incoming damper is normally closed while the bypass
damper is normally open.
Both actuators are spring return so when the
compressor does not have power or is on standby,
the actuators return to their normal position. When
heat of compression is being rejected due to the
outside air temperature setpoint being exceeded , a
signal is sent to control relay 2 (Figure 2-2) which
overrides the control signal and drives the incoming
damper to fully open and the bypass damper to fully
closed. The incoming damper can be set to maintain
a minimum open position with the compressor
running. This ensures fresh air is always entering
the heated space.
2.7 FUNCTIONAL DESCRIPTION
—REJECTED AND
RECOVERED AIR DAMPERS
AND ACTUATORS
Refer to Figure 2-1. Depending on the temperature
of the heated space and the incoming outside air,
heated cooling air will either be recovered or rejected
outdoors.

OR
• The temperature of the incoming outside
air is higher than the set value of the out-
side air temperature controller. Refer to
Figure 2-5.
Operation of the rejected and recovered air dampers
is accomplished with use of two position actuator
motors. Only one damper should ever be open at a
given time. When heat is being recovered, the
recovered damper opens while the rejected damper
closes. Conversely when heat is being rejected, the
rejected damper opens while the recovered damper
closes. Both actuators are spring return so when the
compressor does not have power or is on standby,
the actuators return to their normally closed
positions.
2.8 FUNCTIONAL DESCRIPTION
—POWER PRESENT RELAY
A power present relay (Figure 2-2) is used to prevent
unnecessary operation of the EES components. The
EES system will only operate when the compressor
is running. When power is not provided to the
compressor or when the compressor is in standby
mode and not running, there is no power to the EES
controls or motor actuators. Refer to Figure 2-6.
Upon compressor startup, a signal is sent from the
WS controller to the power present relay located in
the EES electrical enclosure. Power is then provided
to the controls and the EES will function normally.
