Installation Instructions

The WINTSYS® should be installed in a well-ventilated place
with no drafts. Air should be allowed to circulate around the
condenser and under the compressor. There should be no
obstacles to the front or side of the unit, in order to avoid any
recirculation of air in the condenser.
Amongst other things, this will avoid an abnormally high
condensation temperature. The unit should be installed on
level ground. For units installed at high altitudes, the effect of
the air density should be taken into account.
■ 3.4.

Acoustics

Precautions should be taken during installation to avoid
generating unwanted noise or vibration:
- the unit should be solidly attached to a stable, rigid support,
- the piping lines should be sufficiently flexible to avoid the
transmission of vibrations.
It is sometimes recommended to separate the unit from its
support and the support from the wall or the ground, using
joints made of noise-absorbing or anti-vibration materials (not
supplied). In these cases, users should comply with the
manufacturers' recommendations for their choices and
installations. TECUMSEH is not responsible for the choice of
vibration absorbers or their absorption capacity.
■ 3.5.

Attachment

The unit should be installed and fixed on level ground.
The sealing of supports should be performed using means
suited to the type of flooring (not supplied).
- Floor mounting
Do not use wooden rafters as a mounting rail.
Use a concrete base capable of bearing the load and the
vibrations. Use pegs suited to the materials used with an
appropriate seal length.
■ 3.6.

Access to connection points

■ 3.7.
