When installing the pump-motor unit at an altitude of more than 1,000 m [3,280 ft] above sea level, first inquire with the Service department. See rating plate. 3.3 Operating conditions Temperatures Temperature of pumped gases: max. permissible temperature: +40°C [+104°F] Nominal value: +15°C [+59°F] Pump-motor units for higher fluid temperatures on request. Ambient max.
Transport and Handling 4 The transport must be carried out in different ways depending on the type: Transport and Handling 2BH11., 2BH12., 2BH13., 2BH14., 2BH15. (single-impeller): Manual handling WARNING Tipping or falling can lead to crushing, broken bones etc.! Sharp edges can cause cuts! Wear personal safety equipment (gloves, safety shoes and protective helmet) during transport! 2BH15. (two-impeller), 2BH16., 2BH18., 2BH19.
Installation 5 Installation WARNING WARNING Improper use of the unit can result in serious or even fatal injuries! Have you read the safety precautions in Chapter 1, "Safety", Pg. 3 f.
Installation Carry out the following work to install the pumpmotor unit: Minimum distances: Installation and securing, Attachment of the included loose muffler if necessary, Attachment of threaded flange or hose flange (available as accessories) for the connection of inlet or discharge pipe to the muffler, Electrical connection, Connection of inlet and discharge connection to the system.
Installation Sound protection hood (available as an accessory for the 2BH1): Noise protection hoods are suitable for installation in rooms and in the open. They reduce both the total sound pressure level and tonal components that are perceived as particularly annoying. Vertical axis mounting on the wall with the compressor cover pointing downward For vertical axis mounting of the unit on the wall, the unit is fastened using the holes in the foot. The foot of the unit has fastening holes.
Installation The electrical connection must be carried out as follows: Electrical power supply: Observe the rating plate. It is imperative that the operating conditions correspond to the data given on the rating plate! Deviations permissible without reduction in performance: The electrical connection must be permanently safe. There may be no protruding wire ends. Clearance between bare live parts and between bare live parts and ground: ≥ 5.5 mm [0.217"] (at a nominal voltage of UN ≤ 690V).
Installation For motor overload protection: Use motor circuit breakers. This must be adjusted to the specified nominal current (see rating plate). DANGER Electrical danger! There is danger of an electrical shock when a defective pump-motor unit is touched! Mount motor circuit breaker. Have electrical equipment checked regularly by an electrician. Interference immunity of drive motor: For drive motors with integrated sensors, the operator must provide for a sufficient interference immunity itself.

Servicing 9 9.1 Servicing Emptying/Rinsing/Cleaning Before any maintenance/servicing work, empty, rinse and clean the outside of the unit. WARNING Improper use of the unit can result in serious or even fatal injuries! Have you read the safety precautions in Chapter 1, "Safety", Pg. 3 f.? Otherwise you many not carry out any work with or on the pump-motor unit! Empty unit with air and rinse until all residues have been removed. Clean the outside of the unit with compressed air.
Servicing Fault Cause Remedy Carried out by Pump-motor unit does not generate any or generates insufficient pressure difference. Leak in system. Seal leak in the system. Operator Wrong direction of rotation. Reverse direction of rotation by interchanging two connecting leads. Electrician Incorrect frequency (on pump-motor units with frequency converter). Correct frequency. Electrician Shaft seal defective. Replace shaft seal. Service*) Different density of pumped gas.
Disposal 9.3 Service/After-sales service 10 Disposal Our Service is available for work (in particular the installation of spare parts, as well as maintenance and repair work), not described in these operating instruction. A list of spare parts with an exploded drawing is available on the Internet at www.gd-elmorietschle.com. Have the entire pump-motor unit scrapped by a suitable disposal company.
