WARNING
INSTALLATION
● Lethal voltages are used in this
equipment. Use extreme caution when
carrying out electrical checks. Isolate the
power supply before starting any
maintenance work.
● Refer to the safety procedures before
installation of the compressor unit.
1. GUIDELINES
Study the installation information in the manual for
the particular compressor concerned.
The compressor unit is supplied as a complete
package and does not need securing to a
foundation. However, the supporting floor must
have a loading capacity sufficient to support the
weight of the unit (see ‘Leading Particulars’).
Because in operation the compressor will release
heat into the surroundings the compressor room
should be of adequate size and have good
ventilation. The recommended minimum sizes of
room and ventilation openings can be estimated as
follows:
From ‘Leading Particulars’ establish total input
power (kW).
Room volume = 1·35 m
3
per input kW
Ventilation opening = 0·016 m
2
per input kW
Note: An equivalent discharge opening will also be
necessary.
Example:
Cyclon 337 input kW = 44·0
Room volume = 44·0 x 1·35 m
3
= 59·4 m
3
Ventilation opening = 44·0 x 0·016 m
2
= 0·7 m
2
The ventilation inlet opening should be positioned
as low down as possible. The outlet opening should
be positioned as high up as possible, preferably in
the roof or ceiling.
The air flow from the cooler outlet may be directed
either vertically or horizontally simply by changing
the position of the outlet duct which is secured by
fasteners. The air can be ducted for a distance of
up to 3 m if necessary without the need for an
additional fan. Details are available on request from
the local CompAir BroomWade distributor.
To allow adequate air circulation, provide a
minimum of 1·5 m headroom above the
compressor and a minimum of 200 mm clearance
on the RH side. Compressors with horizontal
cooling air discharge must have a minimum of 1 m
and those with vertical discharge a minimum of 150
mm clearance at the back. There should be no
obstruction of doorways, passages or walkways.
The only connections required to the compressor
are as follows:
1. Electrical power supply, 3-phase plus earth.
2. Air delivery outlet to the user’s main pipework
using a flexible hose (optional) or solid pipe.
Model Flexible Hose
330/337/345 C26151-36
Note: If solid pipe is used it must be connected
directly to the outlet of the aftercooler and
supported by the first clamp or support, at least 1 m
from the compressor discharge.
