INSTALLATION
I
CHOICE OF INSTALLATION SITE
Before installing the unit, agree with the customer the site
where it will be installed, taking the following points into con-
sideration:
- check that the fixing points are adequate to support the
weight of the unit;
- pay scrupulous respect to safety distances between the
unit and other equipment or structures to ensure that air
entering the unit and discharged by the fans is free to cir-
culate.
- Follow the instructions shown in the chapter on DIMEN-
SIONAL DRAWINGS to allow room for maintenance oper-
ations. If installing multiple units the clearances must be
doubled.
POSITIONING
Before handling the unit, check the capacity of the lift equip-
ment used, respecting the instructions on the packaging.
To move the unit horizontally, make appropriate use of a lift
truck or similar, bearing in mind the weight distribution of the
unit.
To lift the unit, insert tubes long enough to allow positioning
of the lifting slings and safety pins in the special holes in the
base of the unit.
To avoid the slings damaging the unit, place protection
between the slings and the unit.
The unit should be installed on special vibration dampers.
See the chapter on DIMENSIONAL DRAWINGS for the sup-
port positions identified by W1, W2 etc. and the correspond-
ing weights for the correct sizing of the vibration dampers.
Fix the unit, making sure it is level and that there is easy
access to water and electrical components.
If the site is exposed to strong winds, fix the unit adequately
using tie rods if necessary.
In heating mode the unit produces a significant quantity of
condensate, which must be suitably drained.
Condensate drainage must not cause problems to objects or
people.
If the outside air temperature is less than 0°C, the conden-
sate may freeze; in these case fit a frost protection heater
on the drain line.
For correct operation of the unit, avoid the following: obsta-
cles to air flow, leaves that may block the heat exchange
coil, strong winds that stop or reinforce air flow, sources of
heat too close to the unit, recirculation or stratification of air.
