PRE-INSTALLATION
CODES
Check all applicable codes regulations and permits for installation requirements. Installation must
comply with utility regulations and local codes as well as those of the National Fire Protection
Associations 90A or 90B as applicable.
NOTE: Building of safety codes may require that exhaust fans be interlocked with the make-up air
unit. This requirement is satisfied with an optional ARES exhaust fan control relay assembly or
interface panel.
UNIT INSPECTION
Check unit for shipping damage. If damage is found, report it immediately to the carrier and file a
damage claim.
ROOF LOAD
Roof load-bearing capacity must be adequate to handle the operating weight of the make-up air unit. To
spread this load over additional roof joints and to support the unit above accumulated rainwater, 8"
mounted rails are frequently used.
Check roof loading and structure for support. Approximate operating weights are shown below.
BLOWER HOISTING OPERATION AVG. ROOF
WEIGHT WEIGHT LOADING
(Approx. lbs.) (lbs.) (PSF)
SE1/DE1 470 612 44.8
SC1/DC1 470 470 34.4
SE2/DE2 490 632 46.2
SC2/DC2 490 490 35.8
SC3 525 525 30.5
Hoisting weight includes crate. Operating weight includes water. Hoisting eyes are included to lift the
make-up air unit to the roof.
LOCATION
1. In a roof installation, units should be installed level on a roof curb, rails or roof stand (minimum 4"
high) to allow ventilation beneath the unit. Adequate space for a water drain connection is required
beneath the sump pan of the cooling section, which is also a 4" minimum.
2. If adequate air supply volume is provided, the unit may also be installed on a sidewall. Exact
location will depend upon building construction and the placement of ceiling registers and ducts.
These should be placed carefully to provide maximum distribution of make-up before it is drawn
into the exhaust systems.
3. Install the unit as close as possible to the supply register to minimize duct system resistance (total
external static pressure loss through the duct.)
4. Be sure the unit’s capacity is equivalent to the demands of the systems.
5. Duct velocity should not exceed 1500 FPM.
6. Do not install unit near plumbing vent pipes and exhaust stacks.

7. Natural air circulation must be permitted around the unit at all times.
NOTE:Provide a minimum of 36" clearance at all times around the unit for service access to
Filters, Blower, and Motor and for air circulation.
8. A suitable electrical disconnect switch needs to be installed somewhere in plain view of the
equipment for servicing purposes (this is not a code requirement in all localities, it is a safety
recommendation).
HOISTING EYE INSTALLATION
Remove the blower pad frames.
Position the hoisting eyes on corners of the unit with the angle towards the
center of the unit. (See illustration at right)
Run the bolt through the unit housing and hoisting eye, then attach the nut.
(See illustration at right).
INSTALLATION
DUCTWORK
1. Sizing and layout of ductwork and outlets should provide maximum uniform airflow throughout the
area. Make-up air should be introduced at a location inside the area, but as far away from existing
exhaust hoods as possible to permit conditioned air to flow throughout the entire area before
reaching the exhaust zone, or unless connected to an engineered make-up air system.
2. Ductwork must be adequately sized and designed for minimum resistance (static pressure) to
provide required airflow. Check rating plate for minimum allowable CFM.
3. To avoid pressure losses, all short radius rectangular elbows should have turning vanes, offsets
should not be avoided, and small ducts and takeoffs should be undersized.
4. Main supply duct normally consists of a rectangular vane elbow at the unit and vertical duct
extension, both pieces having the same dimensions as the unit discharge opening. The ductwork
gauge size must be according to local codes. Ceiling registers should be the fixed type (if
adjustable, modify so full closing is not possible). (See illustration below)
CEILING REGISTER
With the make-up air unit in place on the floor, and
the framed roof opening installed:
1. Position roof jack over the opening.
2. Caulk and attach the transition elbow to the
unit with a flexible connection.
3. Push the extension duct up until it slides
through the roof jack into the transition elbow
(the bottom flange of the extension duct
should fit flush with ceiling). Seal, caulk and
secure into place.
4. In the building, center the box over the
opening and secure it.
5. Protect outdoor ductwork with weatherproof
insulation material.
6. This is ARES recommendation but you should
always check local codes in your area.

SE AND DE EVAPORATIVE COOLING
WATER SUPPLY: Water is circulated by a sump pump to troughs above the cooling media. It then flows
by gravity through “V” shaped slots and saturates the cooling filters. A float valve assembly replaces
water lost by evaporation. To avoid build up of organic minerals and salts in the sump, an adjustable
bleed-off valve directs a small stream of water through the overflow drain. An optional fill and drain kit,
which consists of a 3-way valve, 2-way valve and relay itemized for freeze protection of the Make-up Air
Unit water line, is available for field installation.
CAUTION: Damage caused by not correctly installing and servicing the bleed-
off pipe is not covered by the ARES warranty.
Use an inside cold water line that has not passed through a water softening system because salts will
create additional maintenance and upkeep.
1. Install a 1/2" water piping to the right front support leg of the unit. Include a convenient shut-off
valve and provisions for draining to prevent freezing in the piping layout.
2. Install the overflow standpipe in the sump drain (supplied with the unit).
3. Install a drain line between the overflow standpipe (in the sump drain) to a suitable drain (check
local codes).
4. Install float valve assembly through the hole provided in the blower-cooler unit and adjust it so the
water level is approximately 2" deep in the sump pan. (See illustration below).
CAUTION: Damage caused by incorrect water level in sump pan is not covered
by the ARES warranty.
5. Adjust the bleed valve to bypass the main water
line to rid the system of organic and mineral
deposits. (See illustration above)
ELECTRICAL INSTALLATION
1. Check the electrical ratings stamped on the serial
plate to be sure they are correct for use with
available electricity.
CAUTION: Damage caused by incorrect power
supply is not covered by the ARES warranty.
2. The installed unit must conform to all codes and
regulations applying to the job site including
requirements of State and local agencies. All
wiring, grounding and connections must comply with the most current version of the National
Electric Code. Permits should be obtained prior to installation.
3. External controls must be provided to start and stop the fan motor and pump (E models only). An
external mounted starter should be used for motors.

4. Connect power to the motor leads provided. See nameplate for proper voltage and frequency.
5. Check the blower for proper rotation. Interchanging any 2 leads on 3-phase model only may
reverse rotation. Check motor nameplate for single phase.
6. On cooling models, connect the pump leads to the appropriate power
supply. See nameplate for the proper motor voltage.
OPTIONAL ACCESSORIES
The interface panel provides pilot duty switching circuits for interlock operation
of exhaust fans with make-up air units for one or two speeds. (See illustration
at right).
The fill and drain kit provides filling and draining of the sump pan. (See
illustration below)
OPERATION
INITIAL START-UP
1. Check electrical power against the unit’s nameplate.
2. Check airflow through the unit.
3. Re-check that the stand pipe and bleed-off kit have been correctly installed. The adjustable motor
sheave should be adjusted to provide the correct blower wheel RPM to attain the airflow at the
inherent system resistance. Adjust the sheave so the airflow is at or above the minimum shown on
the nameplate. See illustration at right.
4. Check belt tension and alignment. When installing the
belt or adjusting tension, loosen the four motor mounting
bolts and reposition the motor until the belt can be
deflected 1/2" to 3/4" for each foot of belt between the
pulley and sheave. (See illustration at right)
NOTE:Never adjust the belt tension by changing the
setting of the motor sheave. This setting was determined
to provide the correct blower speed for the given CFM
and system static pressure.
5. If ductwork has been installed and unusual static pressure is encountered, the pulley settings may
be changed, providing the blower ampere ratings are not exceeded as indicated on the unit
nameplate.

TROUBLE SHOOTING GUIDE
1. If unit is inoperative, check:
a. Circuit breakers
b. Line fuses
c. Voltage at starter
2. If insufficient cooling occurs, check:
a. Visually check pump operation.
b. Water system obstructions.
3. If low airflow occurs, check:
a. Blower belts slipping
b. Improper motor sheave setting
c. Evaporator or filter pads plugged up
d. Excessive ductwork resistance
e. Blower motor horsepower too low for requirements.
4. If there is mineral buildup on evaporative pads, check: (Evaporative only SE and DE)
a. Insufficient bleed off water
b. Bleed line plugged
c. Insufficient water over pads (hardness of water may necessitate more frequent cleaning
and/or pad replacement).
MAINTENANCE AND CLEANING FOR EVAPORATIVE
COOLING UNITS
WARNING: Use care when working around live voltage, failure to do so may result in
severe injury or death for which ARES will not be responsible.
1. The reservoir pan should be drained and cleaned at least once every cooling season and before
every winter operation; clean pans more often if water conditions require it.
a. Remove the overflow standpipe and allow water to drain.
b. Clean out all sediment and if necessary, paint bare metal or scratches with protective paint
or undercoating.
c. Water distribution troughs must be unobstructed.
2. Inspect cooling filter media monthly for mineral deposits (in hard water areas, mineral salts will
build up quickly).
Be sure filter media is clean and does not obstruct airflow during winter operations.
3. The need for changing filter pads more frequently varies with locality, particularly areas where dust,
alkali and other foreign matter accumulate in the pads.
a. To change filter pads, use ARES filter pads #987360 Coolpad or O5915 Glacier-Cor® for
evaporative cooling.
b. Lay louvered panels on a flat surface with wire filter retainers face up.
c. Remove the center frame support and the filter retainers by pressing down on each end of
the retainers to disengage hooks from the holes in the pad frame.
d. Remove and discard used filter pads. Clean and paint all bare surfaces as needed. Check
slots in the water distribution trough to be sure that they are open and free of obstructions.
Evaporative units only (See illustration on next page top right).
e. Install a new filter pad in the frame. Check that the pad is of uniform thickness
and completely fills the frame to avoid air bypass.
CAUTION: Automatically Operated Device - To Reduce theRisk of Injury, Disconnect From Power
Supply Before Servicing.

f. Reinstall the wire filter retainer in the holes provided on the pad frame.
g. For evaporative cooling units, presoak the pads (already reassembled in the frame) with
water thoroughly for several minutes before reinstalling. This soaking conditions the surface
and the fibers of the pads, increasing water absorbability and filter performance in the
evaporative cooling process.
h. Correct belt adjustment is important as it cuts power consumption and prolongs the life of
the belt and motor.
i. When adjusting the belt tension, loosen the four motor mounting bolts and adjust the motor
until the belt can be deflected 1/2" to 3/4" for each foot of belt between the pulley and sheave.
WARNING: Never tighten the belt by adjusting the motor sheave.
j. The blower motor, blower shaft bearings and recirculating pump on evaporative cooling units,
should be oiled twice a year with SAE 20 weight oil.
