FEATURES INCLUDE:
• Stainless Steel Construction
• The basic size of our cooler is 22”x22”x12.5”, making it the most compact cooler in its class.
• 6 Gallon Hydraulic Reservoir
• Weight: 140 lbs dry, making it the lightest hydraulic cooler in its class
• Flow Rate to 60gpm
• Pressure rated to 3000 psi
• Heat rejection is 28HP at 60gpm with 80°F ETD. This is the highest heat rejection in its class
• Hydraulic filter – This filters your return fluid with a ten micron filter, has an integral bypass valve, and baffle. It also conveniently filters the oil
that is added to the reservoir.
• Filter Element = 10 micron
• Filter Bypass valve- Set at 36 psi. This feature protects the filter from over pressurization due to cold oil or a blocked element.
• System Cold Oil Bypass Valve – Set at 60psi. This feature ensures that the low pressure side of the hydraulic system stays at a low pressure.
Primarily protects from over pressurization due to cold oil.
• System relief valve – This Feature ensures that the maximum system pressure does not go any higher than what you set the valve at. Factory set at
3000psi and is adjustable from 500psi to 3000psi.
• Flow control valve – This feature ensures the delivery of consistent flow to the hydraulically powered cooling blower motor. It is factory set to
ensure the most efficient blower speed.

FIGURE 1: ARC-60 Dimensions

POSITIONING AND MOUNTING:
The ARC-60 is designed to fit in very tight spaces, its narrow profile allows for
behind the cab or frame rail mounting. Unit will ship with a mounting template
to aid in proper installation. (See FIG. 6) The ARC-60 requires at least 2” air gap
on the fan shroud side to allow for adequate air intake.
CONNECTIONS (SEE FIG.2):
Note: SAE ports do not require a thread sealant, they seal with an o-ring. Make
sure your SAE fittings have a properly sized o-ring and
are free of thread sealant.
Suction Port-32 SAE – Your hose will go from this port to the
pump inlet port. Minimum hose size – 2”.
Pressure Port -20 SAE – The hose from your pump output will “T” into this port.
One side of the “T” supplies the 2.25gpm to the hydraulic fan. Flow will only
be greater than 2.25gpm through this line if the pressure relief valve setting is
exceeded. The other side of the “T” runs to the motor input or control valve
input depending on your system. Minimum hose size – 1.0”.
Case Drain -8 SAE – Some hydraulic pumps, motors, and control valves have a
case drain line that needs to be plumbed directly back to the cooler reservoir.
This is where you will make that connection. If your hydraulic system does not
require a case drain line simply leave the APSCO provided hex plug in this port.
This plug also doubles as the drain plug for the tank.
Return Port -24 SAE – The hose from the outlet of your motor or control valve
should be plumbed into this port. This port takes all of the return flow from your
motor and sends it through the filter and heat exchanger built into the ARC-60.
Minimum hose size – 1.5”.
Gauge Port -4 SAE – This is a test port on the bottom of your cooler. This port
is connected to the input port of the manifold, for the purpose of connecting
diagnostic equipment like a gauge or transducer to system pressure.
START UP PROCEDURE:
This Unit comes ready to install, no assembly required.
Make up all hydraulic connections.
With the PTO disengaged, remove filter cap from top of cooler. Leave filter in
place and add fluid until the bottom gauge is full and the top gauge is empty
as shown. This will filter the fluid as it is being added. Even new hydraulic fluid
should be filtered. You will need to add hydraulic fluid in slowly because the
filter is in place.
Bleed air from lines and check fluid level again. Ensure that the lines are full of
fluid and the air is bled from your system, some pumps and motors, particularly
piston will be ruined in a matter of seconds if operated without fluid.
Depending on the length and diameter of the system hoses you may need to add
fluid to the reservoir several times.
Install filter cap.
Slowly engage PTO with engine at idle speed.
Check for hydraulic leaks and repair as needed
Check for fan operation. Note that the fan will turn slowly
when system pressure is low.
Recheck reservoir fluid level. Each time you add fluid
disengage PTO, if the reservoir gets completely empty before
you add fluid you will need to bleed air from the lines again.
Pressure relief valve setting – The ARC-60 pressure relief valve is factory set
to 3000psi. This is a good setting if all of your other system components are
rated to at least 3000psi. Failure to set the relief valve 200psi higher than
system pressure or any other system relief valve will result in excess build up
of heat. If you need to adjust the APSCO
pressure relief valve it can be accessed by
removing the access panel at the bottom
of the cooler and the R.V. side plug to
manually adjust. The change in pressure
is roughly a 125 PSI per quarter turn. Any
time the side cover is off the PTO should
be off as well.
Once you verify system functionality with
no leaks and the proper fluid level your
ARC-60 is ready for operation.
SYSTEM MAINTENANCE:
Filter – Unscrew filter cap (use a screw
driver or tool with a square shank) and
replace element every three months.
Fluid – Check fluid level daily (with the
PTO off the fluid level should completely
fill the bottom sight glass with no fluid showing in the top sight glass). Drain and
replace hydraulic oil every 6 to 12 months depending on use.
Recommended Fluid – Use non foaming hydraulic fluid and see Pump and Motor
Manufacturer recommendations.
Clean Radiator – Use a mild cleaner compatible with aluminum. Be careful not
to damage fins if using a power washer to rinse cleaner off of radiator. Visually
inspect daily and clean if necessary.
INSTALLATION & OPERATION

Warning: High Pressure oil can cause severe
injury. Turn off PTO and bleed pressure
before servicing hydraulic system.
Warning: heavy object. To avoid muscle
strain or back injury, use lifting aids and
proper lifting technique when removing or
replacing.
Warning: Rotating Fan Blade. Can cause
serious injury or cut. Keep hands clear. Turn
off and lockout unit before servicing.
Caution: Surface May be Hot. Ensure PTO is
off and unit has cooled before servicing.

Problem Cause Corrective Action
Fan not spinning
Low system pressure
Low oil level in tank
Air leak in suction hose or fitting connections
Collapsed Suction Hose
Flow Control Valve has blocked orifice
Fan sucked in road trash such as a plastic bag and has caused fan to
be in a bind
The system pressure must be higher than 1000 psi for the fan to spin at
full speed. Slower fan speeds in an unloaded condition are part of normal
operation
Fill Tank, tighten fittings, and bleed air from lines
Tighten fittings and bleed air from lines
Replace suction hose
Remove and clean or replace valve. Change fluid and filter element
With Unit de-energized, remove debris, check for proper torque of hub bolts.
Check to make sure the fan is not broken or cracked and motor functions
properly

ARC-60 REPAIR: (Refer to FIG.5, Table 4)
Be sure to turn off PTO, lockout unit, allow time for fluid to cool, and
bleed hydraulic pressure, before removing any body panels or hoses
on or connected to ARC-60.
Drain hydraulic fluid from unit by removing the case drain plug (Item
17, FIG.3), once all the fluid has been drained replace and torque
according to Table 1. Do not re-use this fluid. Remove all connections
to the ARC60, these connections will be wet so be sure to have a
catch pan for the fluid that will be spilled. Cap and plug all hoses and
ports to prevent contamination. It is recommended to do any repair
work on a clean surface in a dust free environment.
Most repairs, such as fan, motor, relief and flow control valves, can be
accessed by simply removing the left side panel then removing and
replacing the part. To remove the left side panel (Item 7, FIG.5) you
must remove the front and top panels as well. If more in depth repairs
are necessary, simply remove the three manifold bolts and the two
radiator bolts that fasten the manifold and radiator to the base plate.
The entire internal assembly can then be lifted out of the frame.
Once the ARC-60 is out of its frame you will be able to remove and
replace any of the components. If the repair requires you to remove
the tank mount bracket (Item 24, FIG 4) mark the position of the
bolts on the tank mount bracket so you can reinstall in the same
position. This will ensure that your sight glass and tank caps will
fit concentrically within the case when you put the ARC-60 back
together. When you re-assemble the ARC-60 be sure use blue loc-tite
on all fasteners and torque according to Table 1.
