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 condition.
■
3.2. Handling
The packaged condensing unit can be lifted by forklift or pallet
truck. The unit should therefore be kept in its packaging until it has
been moved to the installation site.
Once the packaging has been removed, Silensys units can be
moved or lifted either by forklift or straps according to the model.
Units must not be dragged into position.
■
3.3. Location
Silensys® condensing units should not block or obstruct
thoroughfares, doors, shutters or the movement of personnel. The
surface supporting the condensing unit must be level and capable
of bearing the combined weight of the unit + support.
See table in Appendix 3, page 32 to 33 for condensing unit weights.
Ensure there is sufficient distance between the condensing unit
and objects in the surrounding area to ensure good air circulation.
See Appendix 3, pages 32 to 33
Silensys condensing units must be installed in well-ventilated but
not windy locations. Ensure there is good air circulation to the
condenser. There must be no obstacles in front or to the side of
the unit which would cause air recirculation to the condenser. This

will avoid among others an abnormally high condensation
temperature. The unit must be set up in a level position and
installed at an altitude not exceeding 2000 m.
■
3.4. Noise levels
Silensys condensing units have been designed to operate
extremely quietly.
Precautions must be taken during installation to avoid generating
additional noise and vibrations:
- Units must be securely mounted on a stable, rigid base,
- Connecting pipework must be sufficiently flexible to ensure
vibration is not transmitted to the rest of the installation.
We sometimes recommend isolating material be inserted
between the unit feet and the base or between the wall mounting
brackets and the wall. This can be either an isolating pad or anti-
vibration mounts (not supplied) conforming to the manufacturer's
recommendations for their selection and installation. The
selection of any anti-vibration products and their potential for
absorbing vibration is not the responsibility of Tecumseh Europe.
■
3.5. Mounting (1 or 2 options according to model)
The unit must be installed and affixed on a level plane.
Ensure the unit is securely fixed to the type of floor or wall surface
upon which it is mounted using the appropriated fixings (not supplied).
- Floor mounting
See Appendix 3, pages 32 to 33
Do not use wooden beams as a base onto which the product is
fixed. Create a concrete base strong enough to support the load
and vibration. Use fixing bolts which are of an appropriate length
and are capable of securing the product correctly.
Use the mounting kit supplied with the condensing unit.
- Wall mounting (single fan models only)
See Appendix 3, pages 32 to 33
Use the mounting kit supplied with the condensing unit.
Secure the product appropriately.
■
3.6. Access to connections
See Appendix 4, page 34
■
3.7. Refrigeration connections
To ensure the quality of our products, the condensing unit has been
dehydrated and charged with nitrogen.
On models fitted with suction tube diameter 1 1/8 or 1 3/8 the
suction line from the valve to the end of the tube is not under
nitrogen (the suction line is plugged and the valve closed).
