2 General description
2.1 Overview
WARNING: INCORRECT USE OF EQUIPMENT
Risk of injury or damage to the equipment. Incorrect use of the equipment can cause
damage to the equipment or injury to people. The user is responsible for the safe
operation, installation and monitoring of the system.
The ECODRY plus product family is a range of dry, multi-stage roots vacuum
pumps that offers high pumping speed in a compact form. The pump is
connected by a power cord and is designed for use on clean duty
applications.
The cord ratings are:
Supply voltage (V) Current (A) Frequency (Hz)
100 ‑127 14 50 or 60
200 ‑240 7
The pump is not designed for use with ammable, corrosive, toxic, or other
hazardous gases. Gas or oxygen can mix in the pump.
The dry pumping system can be used in either transient or steady state gas
load conditions. The pump can sustain continuous operation with a
maximum power consumption of 850 W. When the load is more than 850 W
motor power the speed temporarily reduces.When high load passes the
motor speed is increased, or when the transient overload protection has
recovered. Refer to Table: Performance data for information on maximum
inlet pressure.
Refer to Figure: General view, the system is supplied with an DN 25 ISO-KF
inlet port (1) and an DN 25 ISO-KF exhaust port (10).
The pump mechanism is operated by an electric motor driven by an internal
pump controller. The rotational elements of the pumping mechanism are
simply supported at the end by lubricated bearings. PFPE lubricant is used
and this is contained in both the gearbox and motor ends of the pump
module, these are "sealed for life" and the lubricant does not need to be
replaced until the pump service interval is reached.
The system is air cooled by a fan installed internally in the pump enclosure.
The pump has a thermal protection device that will stop the motor if a
thermal overload occurs, for example due to high ambient temperature. If
the thermal protection is triggered, you must restart the pump after it has
cooled down.
The pump is designed to pump the residual gases used in high vacuum
systems. The gases are:
▪Air
▪Nitrogen
▪Krypton
▪Argon
▪Helium

2.3.1 Auxiliary connector socket
An auxiliary control connection on the rear panel controls an optional inlet
valve. This inlet valve can be operated in parallel with the normal pump
output signal. Refer to Figure: General view, (7). The valve is usually closed
and:
▪will open when the normal signal becomes active (pump at speed)
▪will close when you select the stop button or if there is a fault
condition.
The reaction time will be in line with the valve selection and the output signal
is 24 V d.c., refer to Figure: Valve connector for the polarity of the connector
pins when the connector is energized.
The auxiliary connector is regulated to 24 V d.c. to control the accessories. If
the auxiliary load current exceeds the value in Table: Auxiliary load currents,
the output will shut down to protect the pump controller. Refer to Table:

WARNING: HEAVY OBJECT
Risk of physical injury. Use suitable equipment to lift the pump.
WARNING: TRIP HAZARD
Risk of injury or damage to equipment. Make sure that any cables and/or pipe work
attached to the pump are xed carefully to avoid a slip/trip hazard and to prevent any
damage to the cable.
WARNING: LIFTING EYE INTEGRITY
Risk of injury or damage to equipment. Make sure that the maximum angle between
the paired slings used to lift the system is 45 degrees. Increased angle could
compromise the lifting eye integrity.
WARNING: INSTALLATION SAFETY
Risk of injury or damage to equipment. Install the pump in the vacuum system before
you connect the power supply. This will make sure that the pump is not operated and
this will avoid injury during the installation.

WARNING: HEAVY OBJECT
Push-pull hazard with strain injury. Push or pull the pump system only for short
distance and over at surfaces. Lift the system with a correct lifting equipment or two
persons must lift if the oor is uneven or there are obstacles present.
WARNING: EXHAUST BLOCKAGE
Risk of injury or damage to equipment. A peak pressure of 3 bar(g) can be generated
in the pump if the exhaust or pipework attached to the exhaust are blocked.
WARNING: HAZARDOUS SUBSTANCES
Risk of injury or damage to equipment. The pump is intended for clean applications
only. It is not suitable for use with hazardous production materials.
CAUTION: INSTALLATION SAFETY
Risk of injury or damage to the environment. Follow all local legislation when the
pump is installed or removed to reduce the impact of the pump on the environment.
CAUTION: HIGH NOISE LEVEL
Risk of hearing damage. When the pump is operating and is not connected to the
vacuum system (with open inlet) the noise level may exceed 85 dB(A).
CAUTION: CONDENSATE DRAINAGE
Risk of damage to equipment. Use a catchpot to prevent the drainage of condensate
back into the system. Condensate that drains back into the system could damage the
pump.
Obey the instructions that follow when you install the pump:
▪Make sure that there is no blockage to access the pump electrical
supply cable or the other controls.
▪Make sure that there is a minimum air gap of 100 mm on all sides of
the pump to allow effective air circulation.
▪Make sure that the system is on a rm and level surface that can
support the mass of the pump.
▪Make sure that the system is installed away from combustible
materials.
▪Level the pump to a maximum of 5 degrees (measured at the pump
inlet).
▪You must do a risk assessment of the location and make sure that you
can move the pump safely and as per the local and national manual
handling guidelines.
