VANAIR MANUFACTURING, INC.
(844) VAN-SERV • www.vanair.com
CLAIMS PROCESS FOR
WARRANTED VANAIR
PARTS
This process must be used by owners of
Vanair® equipment in situations where a
warranted item needs repair or replacement
under the terms of the purchase warranty.
Do not return items to Vanair without prior
authorization from the Vanair Warranty
Administrator.
PROCEDURE:
When a customer needs assistance in
troubleshooting a system and/or returning
parts, follow the steps below.
1. Locate the machine’s serial number:
The machine package serial number plate is
located inside the machine compartment on
the underside of the hood (see Figure W-1).
The hydraulic motor and the compressor
unit both also have their own individual serial
number/serial plates (see Figure W-1). For
issues particularly involving either the
hydraulic motor or the compressor unit,
these serial numbers may also be helpful for
conveying information. In any case, the
machine serial number can be used to
confirm and process any issue regarding the
machine overall, including the motor and the
compressor.
2. Have a list of the symptoms/condition/
malfunctions along with any applicable
temperature and pressure readings, and
also the number of operational hours
available:
Note that the above information will also
need to be included on the Return Material
Authorization Form (per Step #6); this form
is necessary for warranty processing if the
warranty claim is deemed valid by the
service case review.
3. Contact the Vanair® Service Department
by phone (1-844-VANSERV) to speak with
a Service Technician.
4. Vanair Service will troubleshoot the
problem based on the information
provided by the customer, and attempt to
return the unit to service as quickly as
possible.
5. If the unit cannot be returned to service,
and Vanair determines this matter is a
warranty issue, the Service Technician
will assign an RMA (Return Material
Authorization) number that will provide
for the return of the item to Vanair for
analysis and a final determination as to
the item’s warranty status.
6. Warranty Claims are solicited via a
Return Material Authorization (RMA)
Form. This form can be obtained by
request directly from the Vanair Service
Department:
Once a current form has been obtained,
follow the instructions given on the form to fill
in the information needed. This form is used
for the purpose of soliciting a warranty case.
Customers have 30 days after the RMA
number is issued to return the item. If the
NOTE
The RMA number must be placed on the
outside of the package being returned.

part is not returned within this period, the
RMA is void and any claims will be denied.
Before sending a warranty part to a
customer, Vanair® will need a P.O. or credit
card number to cover the cost of the part and
shipping. After the part is analyzed and
deemed to be covered under warranty,
Vanair will issue credit to the customer. All
parts eligible for warranty must have the
RMA number on the invoice at the time of
purchase.
No items can be returned “freight collect”.
Freight costs will be addressed at the time
the claim is closed. The customer pays any
additional costs for warranty parts delivered
through expedited services (i.e., Next Day,
Second Day).
VANAIR WILL NEVER ACCEPT ANY
INVOICES FOR PARTS RETURNED: ANY
PARTS RETURNED VIA INVOICE WILL BE
RETURNED FREIGHT COLLECT: NO
PARTS ARE TO BE RETURNED FREIGHT

([e-mail]).
NOTE
All labor claims or invoices must be
approved by the Vanair Warranty
Administrator prior to starting repair work
along with the cost of the repair. All
paperwork associated with the returned
item and warranty repair cost must
reference the RMA number issued against
the part, and be forwarded to Vanair

3.2 GENERAL INSTRUCTIONS
This section provides general guidance for
locating and preparing the Vanair RS45
compressor package for operation. Each
installation is unique and can be affected by
location, ventilation, and other factors such
as electrical and hydraulic power supply
availability and location.
NOTE
Before fully unpacking the unit, inspect the
component parts, supports and loose-
packed parts to ensure that there have been
no internal movements of assemblies or
components, which may have been
damaged during shipment.
WARNING
Before performing maintenance or repair
operations on the compressor, ensure that
all power has been removed and locked
out to prevent accidental application.
DO NOT assume that because the
compressor is in a STOPPED condition
that power has been removed.
WARNING
Install, operate, and maintain this
equipment in full compliance with all
applicable OSHA, other Federal, state,
local codes, standards, and regulations.
WARNING
Do not install in any enclosed space
without first contacting Vanair.
WARNING

3.3 DETERMINING THE
COMPRESSOR UNIT
MOUNTING LOCATION
When determining the location to mount the
RS45 unit, the following criteria must be
taken into consideration:
• Refer to Section 3.5, Installation. The
location must allow for the machine
dimensions (Figures 3-3A through 3-3D),
and additional space requirements for
minimum cooling, access and
maintenance.
• The mounting surface must be level and
able to accommodate the four [4]
mounting bolts of the base frame. Refer
to Figures 3-3A through 3-3D for
mounting hole location dimensions.
• The mounting surface must be able to
support the units weight (196 lbs.).
• The external display must be easily
visible to the operator.
It is recommended, for most installations, to
mount the compressor on the driver’s side of
the vehicle. The unit should be situated in
such a manner that the fan (rear) and intake
side (front) are not obstructed. Do not place
the compressor in any location where it can
intake exhaust fumes, dust or debris.
3.4 HYDRAULIC SYSTEM
OVERVIEW
Refer to Figures 3-3A through 3-3D for
hydraulic pump system connections.
Please take into consideration the following:
• The hydraulic flow and pressure
requirements of the system.
• A continuous hydraulic load is necessary
when compressor is running.
• The duty cycle and ambient operating
temperatures.
• Other hydraulic equipment which may
share that same hydraulic supply system
(Vanair® recommends a dedicated pump
and hydraulic circuit).
The hydraulic hoses must be run to the
machine. Verify that hoses are hooked up
properly to ensure proper flow. Also, verify
that the hoses are laid out properly so that
no chafing or kinking of the hoses is
possible. Refer to Section 7.18, Hose
Installation Guide, for assistance with
proper hose layout and connecting functions.
3.4.1 HYDRAULIC SYSTEM FILTRATION
Vanair recommends using a 10 micron oil
filter on the hydraulic oil return line. Flow
rating of the filter must be equal to, or greater
than,
the maximum GPM at which the
system will be operated.
IMPORTANT
Vanair® highly recommends consulting a
hydraulic supply expert for specifying the
correct hydraulic supply components for
vehicle-side integration (including oil
reservoir size, hydraulic pressure relief,
hose size, etc.) for your application.
IMPORTANT
Contaminated hydraulic fluid allowed to
enter the pump will cause malfunction of the
pump controls. Hydraulic system hoses
must be flushed and cleaned prior to being
connected to the unit.
WARNING
Follow all applicable safety
recommendations as outlined in Section 1:
Safety of this manual.
WARNING
Improperly, or non-connected lines will
damage the equipment.
NOTE
The temperature of the hydraulic oil should
not exceed 160°F due to the rating of the
Vanair-supplied hydraulic motor.

3.4.2 HYDRAULIC OIL RESERVOIR
3.4.2.1 DETERMINING RESERVOIR SIZE
In a conventional hydraulic system, minimum
tank size, in gallons, should be equal to the
maximum GPM flow rate, times two (x 2).
3.4.2.2 DETERMINING RESERVOIR
SHAPE
The reservoir structure should be tall and
narrow rather than shallow and broad
(Figure 3-1). A tall, narrow tank is
recommended because:
1. The oil level is well above suction line
opening, avoiding the
possibility of
drawing air into the pump due to a vortex
or
“whirlpool” effect within the tank during
operation flow.
2. Allows for better oil level tolerance level
of the system if vehicle operates at an
unusual (slightly off level) vehicle angle.
3. To keep return flow well below the
surface so it does not break the surface
and cause aeration (cavitation) of the oil.
3.4.2.3 MANDATORY RESERVOIR
FEATURES
• The reservoir should incorporate the
following design features:
• In terms of location of the reservoir tank
within the hydraulic system, note that the
hydraulic pump’s inlet line (suction line
out from the reservoir to the pump)
should be located near the bottom of the
tank, well below the oil level. The suction
line should protrude a minimum of two
(2”) inches into the reservoir to keep it
away from potential contaminant surface
buildup.
• A baffle or baffles should be included to
prevent sloshing, or centrifugal motion of
the oil; the goal is to break up direct flow
of the oil from the return point to the
suction point. This allows for the cooling
action contact with the tanks’ inner
surfaces, and promote separation of any
air or contaminants that interact with the
flowing oil.
• An ideal baffle design would position
several (but not too many) baffles to
promote an ‘S’ shape flow within the
reservoir, as viewed from above. The
area of the end gaps should be at least
twice the area of the suction line
diameter.
• A drain port with plug, situated at the
lowest point of the reservoir, is needed to
assure complete draining. It should be
installed using an
adapter or housing
which does not protrude above the inner
surface of the floor of the tank. It should
be visible and
accessible for removal,
with sufficient space available for
catching the waste oil.
• If the return line entrance to the tank is
located near the top, it should be
extended downward within the tank to
minimize foaming and aeration of the
circulating oil. This extends oil integrity,
which in turn helps to maintain system
performance and reliability.
IMPORTANT
Use only a filter that is specifically intended
for hydraulic systems.

• An in-line filter on the return line is
needed to protect the system against
contaminants being introduced into the
oil. The filter should be mounted
externally from the reservoir in a location
that allows for easy of service access.
• A breather and fill cap is needed at the
oil fill port, which needs to be located
above the system oil level. The breather
cap acts to both filter air that is drawn
into the reservoir as the oil level
diminishes, and bleeds air out as the
level is regained. This maintains
constant atmospheric pressure in the air
volume within the reservoir.
• A sight-glass provides a direct visual
indication of the oil level without having
to open, or otherwise access, the
reservoir.
3.4.2.4 RECOMMENDED RESERVOIR
OPTIONS
Although not essential for an adequately
functioning reservoir, the following
components will contribute to maximize the
hydraulic system’s efficiency and maintain a
quality operational level.
• Magnetic drain plug: Attracts and
concentrates ferrous contaminants at the
drain plug source for easier accessibility
and removal when cleaning tank interior.
• A temperature gauge: Located in
approximation to, or built in to, the sight
glass assembly allows for temperature
reading at a glance.
• Filler port strainer: Prevents large
contaminant particles from blending with
system oil when adding new oil.
• Return line diffuser (splash) plate reduces
velocity of oil flow before return oil
stream merges with the main reservoir
oil volume.
• A reservoir heater: For those systems that
are exposed to cold climate ambients,
having the ability to preheat the hydraulic
oil prior to start up will make for easier
startups, and reduce the strain of
warming up the system under adverse
cold conditions.
3.4.2.5 RESERVOIR FEATURES TO
AVOID
A strainer used to screen the suction line is
not recommended for systems designed for
mobile equipment use. Having equipment
that likely experiences long suction lines,
cold startups and non-tracked or infrequent
maintenance practices may cause this
strainer to potentially promote system strain
(cavitation) than prolong fluid integrity
through filtration.
A pressurized reservoir is not recommended
for vehicles, as its complexity invites too
much potential for loss of system reliability if
it is not properly maintained.
3.4.3 RECOMMENDED HYDRAULIC
SYSTEM SPECIFICATIONS
Refer to Figures 3-3A through 3-3D.
• Flow controller is optional to reduce flow if
necessary. Consult Vanair®.
HYDRAULIC LINES
The following is a minimum requirement and
NO quick disconnects may be used. Lines
are to be kept as straight and short as
possible.
• Pressure port = Standard, #12, 3/4” hose
(located at manifold block)
• Load sense = #4 JIC = 1/4” hose (Used for
closed center system only)
• Pressure relief/case drain = #6 JIC = 3/8”
hose
• Hydraulic suction = Standard, #16, 1”
hose
3.4.4 STANDARDS GUIDELINES
• Hydraulic pressure relief factory set at
3200 psi.
WARNING
Do not operate machine without hydraulic
system completely assembled.

3.5 INSTALLATION
3.5.1 MACHINE LOCATION
It is vital to locate the machine so that there
is no restriction of cooling air through the
enclosure (Refer to Figure 3-2). Cooling air
enters the enclosure at the rear (cooler)
package end of the machine, passes through
the cooler and exits through vents in the
upper sides and the front.
3.5.2 CLEARANCES
Refer to Figure 3-2. Ensure that adequate
surrounding clearance space exists around
the machine to allow for adequate cooling
ventilation through the canopy shroud,
unobstructed service access, and a clear
view of the control panel. An approximate
recommendation of ten (10) inches
clearance, minimum, is needed for proper
cooling circulation, plus any additional
service access room included where
needed.
3.5.3 MOUNTING
Mounting surface or support should be
adequate for the weight of the machine (196
lbs.), and should be level for normal
operation. Mounting holes are located in the
frame footing for four (4) 1/2” hold down
bolts.
3.5.4 SERVICE CONNECTIONS
Refer to Figure 3-3A through 3-3D. Service
connections are conveniently grouped at the
lower rear section of the unit in the base
frame.
3.5.5 ELECTRICAL CONNECTIONS
Refer to Figure 3-3A through 3-3D. This
system is offered with either 12V DC or 24V
DC circuits.
3.5.6 HYDRAULIC SUPPLY CIRCUIT
Refer to the hydraulic flow schematic
drawings (Sections 7.16A through 7.16D). It
is recommended that the compressor unit
possesses a separate pump/flow/return
hydraulic circuit to other hydraulic
equipment. This is to prevent the possibility
of pressure/flow drops that may occur if
other hydraulically-powered equipment is
activated during compressor operation,
which may in turn, cause the compressor to
stall out. Alternatively, use of a diverter valve
will permit hydraulics to power different
equipment selectively.
3.5.7 ROUTING
Refer to Figures 3-3A through 3-3D, and the
wiring diagram. Ensure that all supply hoses
and electrical wiring are correctly specified,
adequately supported, and do not touch or
rest on any sharp edges. Wiring should be
protected with split loom to prevent
corrosion, and consequently, loss due to
down time.
