INSTALLATION
PAGE 28
6.3 MOUNTING
Under normal circumstances a special foundation is unnecessary but verification must be obtained that
the support floor is structurally adequate as well as flat and level. If installed adjacent to vibrating
machinery it may be necessary to bolt down the isolation pads but when tightening, ensure the isolation
pads are not distorted.
If bedplate mounted, ensure floor is level and even surfaced, to prevent distortion.
6.4 CONNECTIONS, PIPEWORK AND FITTINGS
Full consideration must be given to system and pipework layout. Check piping and connections are
suitable for pressures and capacities and if the compressor is flexibly mounted, adjacent pipework must
also be flexible.
Pipework adjoining the compressor should consist of short flexible sections to facilitate maintenance
removal of pipework and absorb any vibration.
It is essential that all pipework is made and installed so that it is not constrained or distorted when
connected to the compressor. Where ever possible use 90° bends with 8" (0.2m) radius, not elbows. This
should provide the discharge pipework with the necessary flexibility to allow for thermal expansion.
Before completing pipework assembly, ensure all port protection plugs and blanks are removed and
suction pipe sections are clear of jointing compound, scale, swarf, dirt or other foreign substance. The
system must be suitably braced to prevent vibration and coupling strain on the compressor. Flexible
suction piping should be suitable to withstand suction collapse.
If suction is from a air main, prevent transfer of liquid from the main to the compressor pipe by connecting
the latter to the top of the main pipe.
Separators and drain traps of adequate capacity should be fitted in an easily accessible low section of
the pipework system to prevent condensate or oil carry-over build up. These must be drained regularly.
The delivery line should incorporate non-return valves, especially for large capacity systems or where
two or more compressors are linked to a common main.
Unloading and control gear piping must be as short as possible.
Reavell compressors incorporate safety valves at all stages as standard equipment to protect the
compressor. They will NOT give protection to downstream piping or equipment. Separate safety valves
should be fitted for these areas.
6.5 DRIVE RECOMMENDATIONS
Details of drive arrangements and non isolation pad mountings are available from Reavell.
An overload device must always be fitted to motors.
Manufacturers terminal box wiring instructions must be observed.
An hours run meter fitted to the motor starter is recommended for efficient maintenance scheduling.
Belt
Drive:
It is very important that the driving and driven pulley grooves are in line and both pulley shafts parallel. V-
belt tensioning procedures follow normal BS.3790, 1981 practice.
Use straight edge for alignment:
