Handling and Setting up (pictures
The filter housing (S) should be easily accessible. There must be a minimum space of 40 cm in front of the suction grid (G) and end cover (b) for
servicing. Cooling air entries (E) and cooling air exits (F) on one sided cooling exit (picture
exit (picture
), must have a minimum distance of 30 cm from any obstructions. The discharged cooling air must not be re-circulated.
The DTA pumps can only be operated reliably if they are installed horizontally.
For installations that are higher than 1000 m above sea level there will be a loss in capacity. For further advice please contact your
supplier.
When installed on a solid base the compressors may be installed without fixing down. If the compressors are installed on a base plate we would
recommend fitting anti-vibration mounts. This range of compressors are almost vibration free in operation.
Installation (pictures
and
These compressors may not be operated without the standard pressure regulating and limiting valves fitted so that the maximum
pressure is not exceeded (see data plate).
The safety valve is a wearing item and must be changed after 10,000 h or at the latest 2 year operation.
For operating and installation follow any relevant national standards that are in operation.
1. Pressure connection at (B).
Long and/or small bore pipework should be avoided as this tends to reduce the capacity of the compressor.
2. The electrical data can be found on the data plate (N) or the motor data plate. The motors correspond to DIN/VDE 0530 and have IP 54
protection and insulation class B or F. The connection diagram can be found in the terminal box on the motor (unless a special plug connection
is fitted). Check the electrical data of the motor for compatibility with your available supply (voltage, frequency, permissible current etc.).
3. Connect the motor via a relevant direct on-line motor starter. It is advisable to use thermal overload motor starters to protect the motor and wiring.
All cabling used on starters should be secured with good quality cable clamps.
We recommend that motor starters should be used that are fitted with a time delayed trip resulting from running beyond the amperage setting.
When the unit is started cold, overamperage may occur for a short time.
The electrical installation may only be made by a qualified electrician under the observance of EN 60204. The main switch must be
provided by the operator.
Initial Operation (picture
)
The desiccant bags in the filter housing (S) must be removed before initial start-up.
Maximum number of starts per hour: 12 (DTA 40 - 80), 10 (DTA 100 / 140)
1. Initially switch the compressor on and off for a few seconds to check the direction of rotation against the direction arrow (O).
Note (DTA 40 und DTA 50): On this initial start the pressure pipework should not be connected. If the compressor runs backwards with
the pipework connected a pressure could build up within the housing which could result in damaged rotor blades.
2. Connect the pressure pipe at (B).
If the length of connection pipework (same pipe diameter as machine connection) is longer than 5 m then we recommend fitment
of ZRK non-return valves to prevent reverse rotation when units are switched off.
The DRUVAC should only be started from stationary.
3. The required pressure ranges can be adjusted by turning the pressure regulating valve (D) according to the symbols on the top of the regulating
valve.
Potential risks for operating personnel
Noise Emission: The worst noise levels considering direction and intensity measured according to DIN 45635 part 3 (as per 3. GSGV) are shown
in the table at the back. When working permanently in the vicinity of an operating compressor we recommend wearing ear protection to avoid
any damage to hearing.
