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
condion.
■ 3.2. Handling
The packaged condensing unit can be lied by forkli or pallet
truck. The unit should therefore be kept in its packaging unl it
has been moved to the installaon site.
Once the packaging has been removed, Silensys units can be
moved or lied either by forkli or straps according to the
model. Units must not be dragged into posion.
■ 3.3. Locaon
Silensys® condensing units should not block or obstruct
thoroughfares, doors, shuers or the movement of personnel.
The surface supporng 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 sucient distance between the condensing
unit and objects in the surrounding area to ensure good air
circulaon.
See Appendix 3, pages 32 to 33
Silensys condensing units must be installed in well-venlated
but not windy locaons. Ensure there is good air circulaon
to the condenser. There must be no obstacles in front or to
the side of the unit which would cause air recirculaon to the
condenser. This will avoid among others an abnormally high
condensaon temperature. The unit must be set up in a level
posion and installed at an altude not exceeding 2000 m.
■ 3.4. Noise levels
Silensys condensing units have been designed to operate
extremely quietly.
Precauons must be taken during installaon to avoid
generang addional noise and vibraons:
- Units must be securely mounted on a stable, rigid base,
- Connecng pipework must be suciently exible to ensure
vibraon is not transmied to the rest of the installaon.
We somemes recommend isolang material be inserted
between the unit feet and the base or between the wall
mounng brackets and the wall. This can be either an isolang
pad or an- vibraon mounts (not supplied) conforming to
the manufacturer’s recommendaons for their selecon and
installaon. The selecon of any an-vibraon products and
their potenal for absorbing vibraon is not the responsibility
of Tecumseh Europe.
■ 3.5. Mounng (1 or 2 opons according to
model)
The unit must be installed and axed on a level plane.
Ensure the unit is securely xed to the type of oor or wall
surface upon which it is mounted using the appropriated
xings (not supplied).
- Floor mounng
See Appendix 3, pages 32 to 33
Do not use wooden beams as a base onto which the product
is xed. Create a concrete base strong enough to support the
load and vibraon. Use xing bolts which are of an appropriate
length and are capable of securing the product correctly.
Use the mounng kit supplied with the condensing unit.
- Wall mounng (single fan models only)
See Appendix 3, pages 32 to 33
Use the mounng kit supplied with the condensing unit.
Secure the product appropriately.
■ 3.6. Access to connecons
See Appendix 4, page 34
