8. OPERATING LIMITS
If the fancoil unit is supplied with chilled water, condensate from the coil will be drained via the con-
densate drain connection.
At water temperatures below dewpoint, condensation may occur on components other than the coil.
This is not collected in the condensate drain, and might drip from under the unit.
Therefore the supply, return and drain pipes must be insulated. In case the valve package is installed
next to the unit, the valve package must be insulated.
In order to avoid any condensation, the water temperature should be kept above the dewpoint.
Output must be calculated based on the actual water temperatures and ambient air condition.

9. INSTALLATION
–
Step 01 through 04 is only applicable to the wall. From step 05 the installation is identical for all
Briza Built-In and Surface mount units.
–
respect the open room around the unit as shown in the manual
–
insulate the valves and connections and pipes with self-adhesive thermal insulation against con-
densation or install secondary drain pans
–
slope the fancoil unit slightly towards the condensate drain to help the water drain
