Should any damage be discovered during
package inspection, contact the shipping
company immediately.

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.

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

Grounding must consist of a minimum two

(2) gauge wire between the instrument

panel, the machine, and the truck chassis.

NOTE

Although much of the information given in

this installation section is detailed, these

guidelines should be considered as

referential material only, due to the diverse

possibilities of the end user’s vehicle

make, model and year, and the unit model

specifications.

NOTE

Install electrical components (circuit

breakers, pressure switches, toggle

switches, etc.) in locations where

exposure to water or moisture will be most

minimized.

Before performing maintenance or repair

operations on the compressor, ensure that

all power has been removed and locked

out to prevent accidental application.

SECTION 3: INSTALLATION RELIANT RS45 AIR COMPRESSOR

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

IMPORTANT

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
and hydraulic circuit).

®

recommends a dedicated pump

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.

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.

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.

3.4.1 HYDRAULIC SYSTEM FILTRATION

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.

PAGE - 8 090126-OP_r0 (JAN-2018)

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,

system will be operated.

NOTE

The temperature of the hydraulic oil should

not exceed 160°F due to the rating of the

Vanair-supplied hydraulic motor.

IMPORTANT

Use only a filter that is specifically intended

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
drawing air into the pump due to a vortex
or

“whirlpool” effect within the tank during

operation flow.

VANAIR MANUFACTURING, INC.

(844) VAN-SERV • www.vanair.com

possibility of

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
which does not protrude above the inner
surface of the floor of the tank. It should
be visible and
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.

090126-OP_r0 (JAN-2018) PAGE - 9

adapter or housing

accessible for removal,

SECTION 3: INSTALLATION RELIANT RS45 AIR COMPRESSOR

• 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

WARNING

Do not operate machine without hydraulic

system completely assembled.

Refer to Figures 3-3A through 3-3D.

• Flow controller is optional to reduce flow if

necessary. Consult Vanair

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

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.

VANAIR MANUFACTURING, INC.

(844) VAN-SERV • www.vanair.com

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.

4.3 NORMAL OPERATION

Following is an overview of the normal
operation of the Vanair RS45 hydraulic
compressor system from start-up to shut­down. This overview of a typical sequence of

events may not cover all situations.

IMPORTANT

If start-up and shut-down procedures are

not followed, damage to the system and its

components may occur.

4.3.1 INITIAL START-UP PROCEDURE: PRE-CHECKS

Following are step-by-step instructions for
the initial start-up of the RS45 hydraulic

compressor system:

1. Ensure the compressor is positioned on a
level surface so that the proper amounts
of oil can be added, if required.

2. Unit should be bolted down.

4. Check compressor oil level

Figures 4-2 and 4-3)

(refer to

.

NOTE

An alternate compressor oil level check can

be accomplished via the compressor sight
glass. Refer to Table 5A, Key #1, in Section

5, Maintenance for details.

Add or drain if necessary to accomplish the
recommended compressor oil level.

WARNING

DO NOT remove caps, plugs and/or other

components when compressor is running

or pressurized. Stop compressor and de-

pressurize system prior to maintenance of

system. Relieve the entire system pressure

by opening the service valve, which will

vent all pressure to the atmosphere.

Wear personal protective equipment such

as gloves, work boots, and eye and

hearing protection as required for the task

at hand.

5. Ensure hydraulic oil to pump inlet, and
prime if necessary.

6. Ensure service valve on compressor is
closed.

7. Engage hydraulic system (PTO or
hydraulic supply) and allow hydraulic oil
to circulate back to tank. When solenoid
is activated, oil should quickly circulate to
the hydraulic motor on the compressor,
and start producing air.

8. Check for leaks.

9. Refer to Figure 4-5. Press the START

button on the Controller, and wait for
the Main Screen (default is the
Pressure Screen). Check pressure and
temperature screens. Pressure may

check schedules should be more frequent
than the normal suggestions given in

Section 5, Table 5A: Routine Maintenance
Schedule.

IMPORTANT

Be sure to leave sufficient room around the

machine for cooling air circulation during

operation. There must be a minimum of ten

(10) inches for the cooler intake, and ten

(10) inches for the sides and rear. Heated

air must be able to vent away from the

intake.

RELIANT RS45 AIR COMPRESSOR SECTION 5: MAINTENANCE

SECTION 5:

MAINTENANCE

5.1 GENERAL INFORMATION

A good maintenance program is the key to
long compressor life. This section contains a
program that, when adhered to, should keep
the compressor in top operating condition.
However, it should be understood that these
intervals are for normal operation in a good
clean environment. More frequent
inspections, oil changes and general
maintenance should be carried out in dusty
environments, high ambient temperatures,
heavy load applications or extended light
load conditions.

Follow the prescribed periodic maintenance
schedules given in Table 5A: Routine
Maintenance Schedule, in this section as
recommended. Failure to follow the
prescribed periodic maintenance at the
recommended intervals will impair the
package safety, performance characteristics,
shorten the package’s life, and will
negatively affect the warranty coverage of

the package.

IMPORTANT

It is important to keep in mind that

operating the compressor package in a

severe environment may require more

frequent service intervals than prescribed

in the periodic maintenance schedule.

Before starting the compressor system,
inspect the machine package for any
suspect condition that may cause a safety
hazard or hamper operation. Replace

damaged components with Genuine Vanair
Replacement Parts.

WARNING

Follow all applicable safety

recommendations as outlined in Section 1:

Safety of this manual.

WARNING

DO NOT remove caps, plugs and/or other

components when compressor is running or

pressurized. Stop compressor and de-pressurize

system prior to maintenance of system.

Wear personal protective equipment such as gloves,

work shoes, and eye and hearing protection as

required for the task at hand.

WARNING

DO NOT work on any electrical components unless

the battery is disconnected.

WARNING

Follow the prescribed periodic maintenance (PM)

schedule as recommended. Perform the required PM

schedule at recommended intervals.

Failure to follow this prescribed periodic

maintenance at the recommended intervals will

impair the package safety, performance

characteristics, shorten the package’s life, and will

negatively affect the warranty coverage of the

package.

CAUTION

Compressors and drive motors generate heat and

create hot surfaces. Use caution when operating or

servicing the compressor system. Some surfaces

and components may be hot.

®

It is important that the compressor oil be of the
recommended type and that it is inspected and

replaced together with the oil filter and air filters, and

5.2 MACHINE MAINTENANCE SCHEDULE

Refer to Table 5A: Routine Maintenance
Schedule. A routine maintenance schedule

based on time and/or hours logged, is given
in Table 5A . The intervals are determined
from machine usage under typical operation
conditions. However, the operator must be
aware that operating conditions will vary
depending on such things as specific
customer requirements, environmental
temperatures and cleanliness of the ambient
air. With this in mind, the specifications given
in Table 5A should be used as a guideline
instead of a fixed agenda. A safe approach
to routine maintenance would be to perform
the given maintenance task more frequently
under harsher conditions.

Vanair provides a routine maintenance parts
list in Section 7, Table 7A. Should a non-
routine part need replacement or servicing,
peruse the various parts list illustrations in
Section 7 to help determine the exact part
and part number in question. Our parts and
service departments are ready to assist in
identifying and/or replacing non-routine
parts.

For assistance in obtaining routine
maintenance or replacement parts, consult

Section 7.1, Parts Ordering Procedure,

and Table 7A: Recommended Spare Parts

List.

Procedures and schedule intervals can be
found in Table 5A: Routine Maintenance
Schedule for routine maintenance items.
Though many components on the machine
will not require maintenance throughout the
productive lifespan of the compressor, some
parts are suseptable to wear on an
indeterminable basis, due to the many
factors involved with day to day operation.

Parts and component group assemblies
found to be most prone to indiscernible wear
factors can be readily identified in this
section, and also by perusing the component
listing found in Table 7A: Recommended
Spare Parts List. For parts not identified in
this section, nor in Table 7A, refer to the
itemize diagrams found in Section 7:
Illustrated Parts List to determine the item’s
identification and part number.

Replacement parts should be purchased

through your local Vanair
where the Vanair RS45 hydraulic
compressor was purchased. If, for any
reason, parts are not available in this
manner, they can be purchased through

Vanair directly.

WARNING

DO NOT remove caps, plugs and/or other

components when compressor is running

or pressurized. Stop compressor and de-

pressurize system prior to maintenance of

system. Relieve the entire system

pressure by opening the air tank drain/

vent valve, which will vent all pressure to

the atmosphere.

Wear personal protective equipment such

as gloves, work boots, and eye and

hearing protection as required for the task

at hand.

Refer to Figure 5-1. Open fill cap SLOWLY;

contents may be under pressure. Loosen

cap only enough to allow top of cap vent
to relieve any possible residual pressure

before removing cap all the way.

5.4.1 ALIGNMENT

There is no need to adjust the compressor
unit/hydraulic motor alignment; alignment is
achieved via the motor-to-unit adapter. In the
case where the drive coupling element

needs to be serviced (refer to Section

5.4.7), alignment is automatically achieved

by securing the motor to the unit via the
motor adapter.

However, in the case where the coupling
element needed to be replaced, or if the
alignment is such that there is excessive
machine vibration, etc., there is a hub

5.4.2 SETTING THE MINIMUM PRESSURE VALVE

WARNING

Before performing maintenance:

Shut down machine, relieve all system

pressure and lock out all power, as per the

Safety Section of this manual.

NOTE THAT THE SYSTEM CAN BE

STARTED REMOTELY:

Always clearly tag the start-up

instrumentation against accidental system

start-ups during maintenance.

Refer to Figure 5-2 and the following

procedure:

1. Start the machine and allow it to assume
idle speed.

2. Start the compressor and allow it to
accumulate pressure build-up.

3. Using the electronic display as a guide,
adjust the grub screw [C] until minimum
pressure level is achieved.

4. Tighten the lock nut [D] to secure the
grub screw at the proper minimum
pressure level.

5.4.3 COMPRESSOR THERMAL VALVE

The thermal valve controls the hydraulic oil
temperature and permits for rapid hydraulic
oil warm up. The valve commences to pass a
portion of the oil through the cooler at 100°F
(37.8°C), and is fully open at 125°F (51.7°C).
The valve is preset, and cannot be adjusted.
If maintenance is required due to a faulty or
failing valve, the complete valve should be
replaced. Consult the Vanair Parts
Department to obtain a replacement valve.

5.4.4 SERVICING THE SYSTEM CIRCUIT BREAKER, FUSES AND RELAY

Consult Figure 5-3. for the locations of the

fuses and circuit breaker. Vanair
recommends using a fuse removal tool,
though pliers will suffice, when removing the

fuse.

PAGE - 30 090126-OP_r0 (JAN-2018)

DANGER

Fuses will need to be replaced if blown
when tripped. When changing a fuse, or
dealing directly with any function of the

electrical system maintenance, always be

aware of the safety warnings given in

Section 1, Safety.

5.4.5 SAFETY SHUTDOWN SYSTEMS

Protection for over-pressure and/or over­temperature is provided. If either condition
should occur, the diverter valve should
activate to divert hydraulic fluid back to the
tank and the compressor will stop. A screen
will appear on the control panel that will need

to be reset to run.

5.4.6 PRESSURE RELIEF VALVE

Although the pressure relief valve has a
reset ring at the cap, DO NOT test the
pressure relief valve by pulling on the reset
ring. The pressure relief valve requires no
safety testing. If faulty, replace the valve
(refer to symptoms and recommendations
given in the Troubleshooting Guide in
Section 6).

5.4.7 REPLACING THE DRIVE COUPLING

WARNING

Before performing maintenance:

Shut down machine, relieve all system

pressure and lock out all power, as per the

Safety Section of this manual.

NOTE THAT THE SYSTEM CAN BE

STARTED REMOTELY:

Always clearly tag the start-up

instrumentation against accidental system

start-ups during maintenance.

With proper care of the machine, the drive
coupling should normally last indefinitely.
However, it may become worn or ruptured
and need to be replaced. To replace the
drive coupling, order replacement element
no. 277764, and follow the procedure below.

NOTE

Alignment checks should not be necessary,

as the machine is factory-set. However,

when performing a coupling element

replacement, proper sizing and offset

measurements must be properly set and

checked to avoid damage to machine and/or

coupling.

IMPORTANT

It is important to remember that the drive
coupling contains wear elements that will

eventually fail. Operator must ensure that the

when removing the cover.

5.4.7.2 COUPLING ASSEMBLY

2. Remove the two capscrews and lock
washers that secure the motor to the
motor mount.

3. Carefully extract the motor from the
mount, pulling directly outward; this will
separate the coupling assembly.

4. Remove the spider coupling element.

5. Carefully wipe the coupling halves with
a clean cloth, and place the new
element into position on the
compressor coupling half.

PAGE - 32 090126-OP_r0 (JAN-2018)

6. Re-insert the motor with the motor-side
coupling half to mate with the coupling
element and compressor coupling half.
Note that the motor coupling may need
to be rotated slightly by hand to achieve
coupling and element alignment.

7. Re-install the two 3/8” capscrews and
lock washer sets to secure the motor to
the motor mount.

8. Before torquing the bolts, perform an
alignment check on the hubs. (see
Section 5.4.7.1).

The following method is used for a full re­installation of a drive coupling system. For
performing an element change only, refer to
Section 5.4.7.1.

1. install and mate coupling hub bore with
driving shaft. Hub should be installed
with the hub body toward the driving

unit (see Figure 5-5 for typical

mounting component arrangement).

2. Position hub on mating shaft. Ideal hub
position is with the pocket face of the

TROUBLESHOOTING

6.1 GENERAL INFORMATION

The information contained in this section has
been compiled from field report data and
factory experience. It contains symptoms
and usual causes for the most common
types of problems that may occur. However,
DO NOT assume that these are the only
problems that may occur. All available data
concerning the trouble should be
systematically analyzed before undertaking
any repairs or component replacement
procedures.

A detailed visual inspection is worth
performing for almost all problems, and may
avoid unnecessary additional damage to the
machine. The procedures which can be
performed in the least amount of time and
with the least amount of removal or
disassembly of parts, should be performed
first. Always remember to:

1. Check for loose wiring.

2. Check for damaged piping.

3. Check for parts damaged by heat or an
electrical short circuit, usually noticeable
by discoloration or a burnt odor.

Should the problem persist after making the
recommended check, consult your nearest

7.18 HOSE INSTALLATION GUIDE

HOSE LAYOUT

CONSIDERATION

1. Hose is weakened when
installed in twisted position.
Pressure in twisted hose tends
to loosen fitting connections.
Design so that machine motion
produces bending rather than
twisting.

2. Ample bend radius should be
provided to avoid collapsing of
line and restriction of flow.

3. Exceeding minimum bend radius
will greatly reduce hose assem­bly life.

WRONG RIGHT

HOSE LAYOUT

CONSIDERATION

4. Use elbows or other adapters
as necessary to eliminate
excess hose length and to
insure neater installation for
easier maintenance.

5. When hose assembly is
installed in a flexing applica­tion, remember that metal
hose fittings are not part of the
flexible portion. Allow ample
free length for flexing.

6. When properly routing, use
clamps to secure the hose in
its proper position.
