3- INSTALLATION

■ ■ 3.1.■Unpacking
Before unpacking the unit, check that the packaging has not
been damaged in any way and that the exterior is in good
conditi on.
■ ■ 3.2.■Handling
The packaged condensing unit can be lift ed by forklift or pallet
truck. The unit should therefore be kept in its packaging unti l it
has been moved to the installati on site.
Once the packaging has been removed, Silensys® units can
be moved or lift ed either by forklift or straps according to the
model. Units must not be dragged into positi on.
■ ■ 3.3.■Locati ■ on
Silensys® condensing units should not block or obstruct
thoroughfares, doors, shutt ers or the movement of personnel.
The surface supporti ng the condensing unit must be level and
capable of bearing the combined weight of the unit + support.
See table in Appendix 1, for condensing unit weights.
Ensure there is suffi cient distance between the condensing
unit and objects in the surrounding area to ensure good air
circulati on.
See Appendix 3
Silensys® condensing units must be installed in well-venti lated
but not windy locati ons. Ensure there is good air circulati on
to the condenser. There must be no obstacles in front or to
the side of the unit which would cause air recirculati on to the
condenser. This will avoid among others an abnormally high
condensati on temperature. The unit must be set up in a level
positi on. For units installed at high alti tude, it is necessary to
take into account the eff ect of the density of the air.

■ ■ 3.4.■Noise■levels
Silensys® condensing units have been designed to operate
extremely quietly.
Precauti ons must be taken during installati on to avoid
generati ng additi onal noise and vibrati ons:
- Units must be securely mounted on a stable, rigid base,
- Connecti ng pipework must be suffi ciently fl exible to ensure
vibrati on is not transmitt ed to the rest of the installati on.
We someti mes recommend isolati ng material be inserted
between the unit feet and the base or between the wall
mounti ng brackets and the wall. This can be either an isolati ng
pad or anti - vibrati on mounts (not supplied) conforming to
the manufacturer's recommendati ons for their selecti on and
installati on. The selecti on of any anti -vibrati on products and
their potenti al for absorbing vibrati on is not the responsibility
of Tecumseh.
■ ■ 3.5.■Mounti ■ ng■(1 or 2 opti ons according to
■range
® model)
The unit must be installed and affi xed on a level plane.
Ensure the unit is securely fi xed to the type of fl oor or wall
surface upon which it is mounted using the appropriated
fi xings (not supplied).
- Floor mounti ng
Do not use wooden beams as a base onto which the product
is fi xed. Create a concrete base strong enough to support the
load and vibrati on. Use fi xing bolts which are of an appropriate
length and are capable of securing the product correctly.
Use the mounti ng kit supplied with the condensing unit.
- Wall mounti ng (single fan models only)
Use the mounti ng kit supplied with the condensing unit.
Secure the product appropriately.
Make sure that the wall bracket supports at least 250 kg pull-out
at the att achment point.

To ensure the quality of our products, the condensing unit has
been dehydrated and charged with nitrogen.
On models fi tt ed with sucti on tube diameter 1 1/8 or 1 3/8 the
sucti on line from the valve to the end of the tube is not under
nitrogen (the sucti on line is plugged and the valve closed).
