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.
The use of extension cables is not recommended as this may cause voltage drops which
can result in damage to the motor.
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
