Installation – Mechanical
The Importance of a Proper Installation
As with all Air Compressors, a proper installation is key to both a) long Compressor life and b) quality compressed
air. A Compressor Unit not installed correctly, and coupled with a poor maintenance program, can be plagued
with costly issues not covered by the manufacturer’s warranty.
The drawing below indicates the components required for a good installation.
As the ‘H40’ and H50’’ Screw Units do not include an Air Receiver, one must be located as shown. And though
additional filtration and a Refrigerated Dryer is shown, they may not be required in all instances, this is dependent
on the quality of compressed air required.
Additional dry Air Receiver down-stream
could assist for demand surges.

Moving of the Unit.
When moving the Air
Compressor, the forklift or hand
lift forks go under the Unit from
the directions as indicated.
Slots in the Unit Base are
provided for moving of the
Compressor.
Please be advised that care
must be taken when moving and
positioning the Units as they may
be top heavy.
Location of the Unit.
Items to consider when installing the Unit are as
follows:
The Unit should be located 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 48” (1220mm) around and
60” (1524mm) 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 level on
the floor.
If installed in a compressor room, ensure that the
room is adequately ventilated. (One Horsepower
produces approximately 2500 BTU/HR.) See
Page 10.
The ambient temperature should be between
10°C to 40°C (50°F and 104°F).
H40, H50, H50VSD-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 vibration transmitted through
the floor; use Vibration Pads to lessen this.
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.
The Compressor must not be operated in
a confined area where the heat from the
Unit cannot readily escape.

Lubrication
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 when necessary.
Use only DV Systems ‘DEV-3000’ Synthetic Oil. As
well, do not mix the ‘DEV-3000’ with any other
lubricant.
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 Metal Band on the
External Oil Level Gauge as shown below. Do not
under or overfill. See drawing below.
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’.

Preventative Maintenance Schedule
When servicing the Air Compressor, shut off all
power to the Unit, and drain it of air pressure.
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 damage to the internal components
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 it’s properties, this causing internal damage to components as well
to combat this, the oil must be changed more often than noted below.
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 ‘Maintenance Schedule’ on Page
17) must be changed more frequently.
Regular Maintenance Items.
DV Systems offers a Maintenance Kit for your Unit,
namely:
MK-H50 40/50 HP ‘H Series’ Units
Each Kit consists of the following items, follow
Schedule Table on page 17 for the Maintenance
Schedule.

Variable Speed Drive
Your DV Systems ‘H Series’ Rotary Screw Compressor Unit may have been equipped with a ‘Variable Speed
Drive’, or ‘VSD’. A Compressor with an integral VSD can handle the constant loads for an extended period of time
(running at 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 an ‘H 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.

Motors. Typical Dryer Operation.
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.
Typical Fault Codes.
The readout will indicate a variety of ‘fault codes’, the most common being as follows:
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.
