2 Operating Manual Your Bambi Air Compressor is a precision engineered product. By following these simple steps you will ensure years of trouble free use. Parts & Service are available from your Bambi dealer It is important to quote Model, Type & Serial Number in all communications. The substitution of parts not manufactured nor approved by Bambi can impair performance, service life and create potential mechanical or personnel hazards and will invalidate your warranty. Bambi reserves the right to modify the contents of this operating booklet without notice and the information is in no way binding on the company. Warranty Provided the operating instructions have been followed and the compressor has been properly maintained Bambi compressors are guaranteed against faulty workmanship for a period of 1 year. The air receiver is guaranteed for years. The guarantee does not cover damage by misuse, incorrect parts or service. Contact Bambi Air Compressors or your retailer for further information.

3 1 Safety Precautions What you must do Read these instructions before using your air compressor Ensure the compressor has been installed, electrically connected and piped in by a properly qualified person. Ensure the compressor is kept upright at all times What you must not do Do not attempt any maintenance on the compressor until it has been isolated from the power supply Do not attempt any work on the compressor until the air receiver and pipe work systems are depressurised. Compressed air is dangerous if misused and can prove fatal. Avoid any bodily contact with compressed air During operation the motor will become quite hot to the touch. Avoid contact to prevent burns. Never tamper with the pressure relief valve Never lubricate the oil free motor or pump assembly, this will cause severe damage. Never obstruct cooling fans or outlet vents Siting The Compressor What you must do Provide adequate protection from the weather Site the compressor level in both plains Larger models are heavy, ensure the surface has sufficient load bearing capacity Allow access for maintenance all around the compressor Site in a dry area, avoiding damp or humid conditions. The site must be dust free, well ventilated and have a cool ambient temperature. 0 C should be regarded as the maximum allowable ambient What you must not do Enclose the compressor or allow hot air generated by the motor to re-circulate around the compressor. Ensure there is 30cm clearance around the compressor Restrict air flow around the after cooler or after cooler fan unit Electrical Connections Where applicable, compressors are supplied with a moulded plug in accordance with national standards. Never remove the moulded plug. Note! Duplex models VT300/300D, VT00/00D must be connected to a dedicated fused 20 amp supply. Wired in accordance with European Standard Blue = neutral Brown = live Yellow & Green Stripe = earth

4 2 Operation Refer to exploded parts diagrams and illustrations when reading this section. Starting & Stopping Plug the compressor into an outlet socket of nominal voltage and fitted with the correct fuse as shown in section Electrical Connections. Switch the compressor on using the O/l switch located on the pressure switch - see figs 1&2. The compressor will start running and automatically switch off at the preset pressure. Note! Duplex models VT300/300D, VT00/00D are fitted with a sequential start system to reduce electrical loading. You will notice one motor starting a few seconds after the other. This is normal. As air is used the pressure drops and the motor will restart at the preset pressure. Approx 2 Bar differential. Note! Each time the compressor switches off or the power supply is interrupted, you will hear a short hiss of air. You are hearing the unloader valve discharging the residual delivery pipe pressure. This is normal.

5 3 Operation Dryer Models When equipped with an air dryer unit, the compressor will automatically dry the compressed air before it is stored in the air receiver. This happens automatically and requires no additional maintenance. This eliminates the need to manually drain the air receiver. Operation is similar to standard versions with the following change :- Each time the compressor switches off or the power supply is interrupted, the dryer purge valve opens and automatically activates the drain valve on the after cooler filter allowing the dryer tower to regenerate. All accumulated moisture will discharge into the condensate tank. This should be emptied when it reaches ¾ full. See fig. Note! Waste condensate must be handled in accordance with national environmental rules. Do not exceed the recommended 0% duty cycle, otherwise the dryer will not activate and the humidity of the air will increase. Ensure the after cooler fins are kept clean of accumulated dust. Adjusting Outlet Pressure Use the pressure regulator to adjust the outlet pressure. The 0mm pressure gauge indicates the selected pressure. To increase line pressure rotate the black knob on top of the filter regulator in a clockwise manner, to decrease turn anti clockwise. It is possible to lock the setting by pushing the knob down until it clicks home see fig 3.

6 Routine Maintenance Draining the Air Receiver Drain condensate from air receiver at a pressure of no more than 2 Bar. Slowly open the drain tap provided to allow water to flow out see fig. Close drain tap when all water has drained off. Automatic drains where fitted do not require draining, however the condensate tank will require emptying see previous section Operation Dryer Models. Check Pressure Relief Valve Ensure the air receiver is not pressurised. Unscrew the knurled end of the pressure relief valve until an audible click is heard. Retighten without using excessive force - see fig.

7 Technical We recommend the compressor has a maximum 0% duty cycle to prolong pump life. The motor must never be allowed to run continuously otherwise it will overheat and may become damaged Do not ignore air leaks. All air connections must be leak free to prevent the compressor from over heating. The compressor is fitted with a thermal overload. In the event of excessive temperature the motor will switch off. To re-set the overload follow the procedure below :- Models VT7/7D, VT10/10D, VT200/200D Motor Sizes 0.7Hp, 1.Hp, 2.0Hp Switch off at the pressure switch. Allow 0 minutes for the motor to cool down. Switch on at the pressure switch. Models VT300/300D, VT00/ 00D Motor Size 2x1.Hp 2x2.0Hp The re-set is integral with the pressure switch. The pressure switch will automatically turn off (O) in the event of motor overload. Turn the pressure switch to the on position (I). You must find the cause of the overload and rectify this before continuing to use the compressor. Check for - Drain tap not closed properly Air leaks on the pneumatic fittings Compressor not the correct size for the work load If problems persist contact your dealer.
