Installation; Suggested Fuse Ratings - Clarke SE Series Operating & Maintenance Instructions

INSTALLATION

Before installing your machine, check that its air output is sufficient for the equipment
to be used. The air output from the compressor must be more than the volume of
air required. We recommend the following:
1. Firm and level site, and the use of floor mountings for stationary compressors
- anti-vibration pads. (Do not bolt machines directly to the floor).
2. Dust and damp free environment.
3. Adequate ventilation for:-
a) Air intake to compressor pump (in order to draw in clean air).
b) Cooling to compressor pump, and electric motor.
4. To allow sufficient access for servicing, a minimum clearance of 500mm must
be allowed around the machine.
5. The power cable from the main supply must be large enough to carry the
starting and running load of the electric motor. This is particularly relevant if
the compressor is some distance from the source of supply.
6. Electrical installations should be completed by a qualified electrician.
7. Electrical connection to the mains supply must be via a suitably fused (see
table below) approved plug or isolator (allowing sufficient capacity for motor
starting). If using a circuit breaker, ensure it is motor rated and of sufficient size
to allow for motor starting.
8. Compressors should be connected to mains electricity supply via an earth
leakage protection device (RCD).
