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.
2) Siting The Compressor
What you must do:
• Provide adequate protection from the
weather.
• Site the compressor level in both
planes.
• 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:
• 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, after cooler fan unit or end
cover ventilation [S models].
Important ! For Silenced VTS Models:
These compressors generate heat.
Never restrict any of the ventilation grilles
otherwise serious damage may occur.
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 –
Single phase: Blue = neutral, Brown = live, Yellow & Green Stripe = earth
Three phase: Brown/Black/Grey = Phase conductors
Blue = Neutral
Yellow and Green Stripe = earth
Three phase compressors should be connected by a competent person
All three phase units require neutral supply
