When moving the Air
Compressor, the forklift or hand
lift forks go under the Unit from
the directions as indicated.
When lifting from position ‘A’,
use extended forks.
Please be advised that care
must be taken when moving and
positioning the Units as they are
top heavy.
The Compressor must not be operated in
a confined area where the heat from the
Unit cannot readily escape.
Installation –Mechanical
Moving of the Unit.
Location of the Unit.
Items to consider when installing the Unit are as
follows:
The Unit must be located indoors, in a dry, clean,
cool, dust free, and well ventilated area. If
possible, the Compressor should be located in
a separate room or area, away from the
general operations of the shop.
Allow a minimum of 18” (458 mm) around and 3
feet (915 mm) above the Unit for easy access
to the various sides, this being for both the
proper ventilation of the Unit and ease of
servicing.
Ensure that the floor under the Unit is smooth,
level and capable of bearing the weight of the
Compressor. The Compressor must sit
squarely on the floor.
Ensure that the Unit is anchored to the floor using
isolator pads.
If installed in a compressor room, ensure that the
room is adequately ventilated. (One
Horsepower produces approximately 2500
BTU/HR.) See Page 7.
The ambient temperature should be between
50°F and 104°F (10°C to 40°C).
If installing the Unit on a mezzanine, ensure that
the structure can safely support the weight of
the Unit. As well, the sound level of the Unit
may increase due to the harmonics created by
the structure; use Vibration Pads to lessen this.
When anchoring the Unit, ensure that there is
approx.. ¼” (0.75cm) between the Nut and the
Compressor Foot (as shown below). Do not
bolt down tightly.
Many common Compressor problems can be
attributed to the location or installation of the Unit.
Make sure the Unit is in a suitable location, and
installed correctly.

Lubrication
Oil Fill Port
Oil Drain Valve
Oil Drain Tube
Oil Reservoir
Initial Start-up.
Each Compressor Unit built is extensively tested at
the factory before shipment. The Unit is shipped with
the original oil in it as used for testing purposes.
Check the Oil level and for any Oil leaks on a daily
basis. This must be done when the Unit is off. Top up
the Oil level on a monthly basis.
Use only DV Systems ‘DEV-3000’ Synthetic Oil.
Subsequent Oil Changes.
Drain the existing oil from the Unit. (Please be
advised that the Unit cannot be drained fully of oil, as
some oil may remain in various components ie
Cooler, Tubing, etc.)
Fill the Oil Reservoir to the center of the Sight Glass,
as shown below. Do not under or overfill.
Use only DV Systems ‘DEV-3000’ Synthetic Oil,
available in both 1 US gallon (3.8 litre) jugs or 5 US
gallon (5 x 3.8 litre) pails. Any remaining oil may be
used for ‘top-ups’.
The ‘MK-C7-15-1’ Maintenance Kit includes:
(2) US Gallon (3.8 litre) Oil (‘DEV-3000-K1’)
(2) Oil Filter (’DSC-603’)
(1) Air/Oil Separator Filter (’DSC-302’)
(2) Air Filters (’DSC-001931’)
(1) In Line Filter (‘DSC-612)
(1) Scavenge Line Tube (‘DSC-382’)
Do not attempt to operate the Unit without
first checking whether there is oil in the Oil
Reservoir. Add oil as required. Serious
damage may result from use, however
limited, without oil.
Use of improper oil may negatively affect
Compressor performance or shorten Unit life.
Resulting problems are not covered by the
DV Systems Inc. Air Compressor Warranty.
Condensation (water) may form in the Oil
Reservoir with the oil. If this occurs, as the
water will tend to settle on the bottom of the
Reservoir, drain the water from the Reservoir
until you notice oil draining. Top up the
Reservoir with new oil using only the DV
Systems ‘DEV-3000’ oil.

AC Motor Maintenance Instructions
Cleaning.
To ensure that the Motor operates at optimum temperatures and provides years of trouble-free service,
periodically clean the outside of the Motor Housing of any build-up of dust, etc. Though it is not anticipated that, if
installed correctly and in a suitable environment, there should not be much build-up on the Motor, keeping the
Housing clean will allow the Motor to operate more efficiently.
Lubrication.
This is a ball bearing motor. The bearings have been lubricated at the factory. Motors that do not have regrease
capability are factory lubricated for the normal life of the bearings.
Noted below is a chart outlining the interval at which the Motor should be lubricated, this based on the Motor
horsepower. This must be part of a regular maintenance schedule.

Initial Start-up
1) Remove the LH Front Access Panel, and ensure
that there is sufficient Oil in the Oil Reservoir.
Refer to the ‘Lubrication’ section (page 8) in this
manual for proper type and level of Oil.
2) Do a visual inspection of the Unit, and ensure
that all fasteners are sufficiently tightened. This
must be done, as some fasteners may become
loose in transit.
3) Place the Fused Disconnect / Breaker in the ‘On’
position. Check that there is power to the
Controller
Start-up Procedures
Unit Controls
Do not place any materials in close proximity
to the Compressor. Placing materials against
or close to the Unit will limit the cooling
required, and could lead to premature failure.
4) During normal operation of the Unit, keep the
Access Panels closed at all times.
5) Ensure the Ball Valve on the Unit is closed, press
the ‘Start’ Button, and run the Unit up to
maximum pressure. The Unit will run up to
approx. 145 psi (10bar), at which point the Motor
will continue to run but not compress air.
6) Once the Unit reaches 145 psi (10bar), it will idle
for 5 minutes and shut off. For VSD units, the
unit will idle for 2 minutes and shut off.
7) Open the Ball Valve slightly and allow the air to
bleed from the Tank. Once the pressure reaches
approx 125 psi (8.6bar), the Unit will start and
begin to compress air after a short delay. For
VSD units, this pressure is 135 psi (9.3bar).
8) Measure the amp draw as the Unit reaches
maximum pressure.
9) Close the Ball Valve, allow the Unit to reach
maximum pressure, idle, and shut off. Once off,
check the various fittings etc inside the Cabinet to
ensure there are no internal leaks.
10) Once you are confident that there are no internal
leaks, the Unit will be ready for normal use.
11) Register the Unit to Activate the Warranty by
completing the Warranty Registration form at:
gdg.gardnerdenver.com/DV-Rotary-Warranty
Shut off all power to the Compressor Unit
before attempting any repair or maintenance.
Adjusting the settings of the Controller could adversely affect
the performance of the Unit. Only those individuals with
knowledge of the Unit should make any adjustments.

Preventative Maintenance Schedule
Noted on the following pages are general Maintenance guidelines based on average working conditions. Should
the Unit be worked under extreme conditions, please contact your DV Systems Distributor for further input. As
well, all maintenance/service work must be carried out by a qualified Technician.
The typical operating temperature of the Unit, this dependent on ambient temperatures, is between 70°C and
85°C (158°F and 185°F).
If the operating temperature of the Unit is too low (less than 70°C (158°F)):
condensation will build up in the system and mix with the oil, causing internal component problems in the
Unit
Change the ambient conditions to increase the operating temperature.
If the operating temperature of the Unit is too high (above 85°C (185°F)):
the oil will oxidize and lose its properties, this causing internal damage to components as well
to combat this, the oil must be changed more often than noted below.
When servicing the Air Compressor, shut off all
power to the Unit, and drain it of air pressure.
It is the responsibility of the Compressor owner
to ensure that a regular Maintenance Schedule
is followed.
Note: For Compressor Units used in an environment where the ambient temperature is above
32°C (90°F), the components marked with a ‘ # ’ (on the chart on the following page) must
be changed more frequently.

Variable Speed Drive
Your DV Systems ‘C Series’ Rotary Screw Compressor Unit may have been equipped with a Vacon ‘Variable
Speed Drive’, or ‘VSD’. A Compressor with an integral VSD can handle the constant loads for an extended period
of time (running at close to 100% duty cycle), but it can also run at slower speeds to accommodate lower air
demands at other times of the day.
Variable Speed Drives can reduce the overall energy costs associated with operating the Compressor Unit by
simply controlling the speed of the Motor and Air End to match consumption. As Rotary Screw Compressors
using the variable speed technology match the varying air demands and therefore have the ability to impact your
energy consumption, some energy providers have offered rebates when these Units are purchased. Consult your
local energy provider to determine if this applies.
Shown below is a ‘C Series’ Unit with a Variable Speed Drive.
VSD Interface
The VSD Controller Interface is shown at right. It
provides a means of operating, monitoring, and adjusting
the parameters of the Variable Speed Drive.
Please note that adjustments to the parameters of the
Variable Speed Drive should be made only by qualified
Technicians, or with the guidance of factory trained
personnel. Incorrect adjustments will affect the
performance of the Unit, and could result in damage to
the Drive.

Separator Filter and Refrigerated Air Dryer
Your Unit may be equipped with a Separator Filter and an ‘ASD Series’ Refrigerated Air Dryer Unit as indicated
below. These items are located in the compressed air lines after the air is compressed but before it enters the Air
Receiver. This allows for what is termed a ‘dry’ Tank.
*Drains will discharge automatically under pressure. It is recommended that pneumatic drain tubes be anchored
and filtered as per your local municipality regulations.
More detailed information concerning the Dryer Unit is included in the Dryer manual. The information contained in
this manual is a ‘quick reference’ only.

Separator Filter and Refrigerated Air Dryer (cont’d)
The Dryer will operate as follows:
Pressing the ‘On/Off’ Button for 3 seconds will start the Unit
There is a time delay of up to 2 minutes before the Refrigerant Compressor starts.
The Condenser Fan will start approx. 30 seconds there-after.
The Fan will not normally run at full speed, this indicated by a flashing LED
The readout will initially show ambient temperature indicated by 3 horizontal bars on the readout
Once the Fan and Compressor start, the dew point of the Unit will decrease to approx. 1°C, this indicated
by 1 or no horizontal bars.
Once at approx. 1°C, the Fan will stop, only to be called to run again once the temperature increases to
approx. 5°C
Pressing the ‘On/Off’ Button (when the Unit is operating) will run the Fan at full speed for several
seconds, after which the Unit will stop. (The LED will be on continually while the Fan runs at full speed.)
As well as showing the dew point, the readout may indicate several fault codes as suggested below.
The readout will indicate a variety of ‘fault codes’, the most common being as follows:
Motors.
Typical Dryer Operation.
Typical Fault Codes.
Energy Saving Mode.
The Dew Point has been running at below -1°C for over 6
minutes.
The Unit will automatically restart operation at 6°C.
Temperature Probe Alarm.
The Temperature Probe is not working properly. It may
not be connected to the Board, or the Probe may be
defective.
Replace the Probe if necessary.
High Temperature Alarm.
The Dew Point has been running at above 12.5°C for
over 6 minutes. The Unit must be manually turned off and
on.
The fault could be caused by a dirty radiator, high
ambient temperature, a faulty Fan, or a faulty refrigerant
Compressor, to name only a few.
