2.7.- UNIT INSTALLATION
1.- The EcoLeanTM units could be installed outside or inside.
2.- See the minimum clearance diagrams for access - air supply to the batteries in the heating section of the unit (see page 28).
3.- Assemble the unit on a resistant base, preferably concrete. To prevent vibrations, the concrete base should not come into
contact with the building’s foundations.
4.- It is advisable to assemble the unit on shock absorbers (antivibration mountings).
5.- During heating mode (heating pump coolers) ice forms in the coils. The defrost process is activated during heating mode in
heat pump units, when the outside temperature is low and the outdoor coil could become frozen.
To melt the ice, the defrost function will switch the unit to cooling operation for a short period. When the evaporation
temperature starts to drop, a defrost period sets in to provide sufficient heat transfer. During defrosting, the ice melts from the
batteries. As a result, the ice contains water which must be removed.
WARNING
If the unit is exposed for long periods to installation conditions below 0ºC the water from defrost can freeze in the
base of the unit. This prevents drainage. Ice build up can occur preventing correct operation. For these conditions
contact customer service team.
6.- The heat exchanger water flow during cooling must be the same as during heating.
7.- Fit a water filter in the unit inlet.
It is obligatory to install a mesh filter in units not equipped with Hydronic or Hydraulic module. The step of the mesh
should not be superior to 1 mm.
8.- Use water treating if necessary.
9.- The water inlet to the circuit has to be filled from lowest point, with purges opened, to prevent air being trapped.
10.- Location inside:
For location inside, keep in mind following advice:
- In heat pump units during defrost cycle, the units produce a great amount of water melting the ice off coils.
If you wish to drain the water, adequate drainage should be installed below the unit to collect and carry out the water where
desired.
- Air duct installation:
If air duct has been installed, the operating limits get reduced (see operation limits section in this manual).
(1) The air intake plenum (option) available for models from 0251 to 1403 makes easier the installation of the air intake duct
(see page 24).
(2) The discharge plenum (option) lets the installation of a square discharge duct for the high static pressure units FP1 and FP2
(see page 24).
In heat pump units with double circuits and cooling only
units 1003SM to 1804SM, if only one duct is going to be
installed, a regulated pressure damper should be installed
for each fan, to avoid air by-pass through the fan if it has
stopped.
