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 5 years.
The guarantee does not cover damage by misuse, incorrect parts or service.
Contact Bambi Air Compressors or your retailer for further information.

Safety Precautions
Siting The Compressor
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 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. 40 C
should be regarded as the maximum
allowable ambient
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
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, VT400/400D must be connected to a dedicated fused 20
amp supply.
Wired in accordance with European Standard –
Blue = neutral Brown = live
Yellow & Green Stripe = earth
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, VT400/400D 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.
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 6.
Note !
Waste condensate must be handled in accordance with national environmental rules.
Do not exceed the recommended 50% 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 40mm 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.
4
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 4.
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 5.
5
Technical
We recommend the compressor has a maximum 50% 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 VT75/75D, VT150/150D,
VT200/200D
Motor Sizes 0.75Hp, 1.5Hp, 2.0Hp
Switch off at the pressure switch.
Allow 50 minutes for the motor to cool
down.
Switch on at the pressure switch.
Models VT300/300D, VT400/
400D
Motor Size 2x1.5Hp – 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.
