Safety check
7.1.1 Pre-commissioning checklist
–
The entire facility comprising HyCassette-Geko units has been installed both
mechanically and electrically.
–
The system and HyCassette-Geko units are disconnected from the power
source.
–
All medium pipes have been flushed and are free from residues and foreign
matter.
–
The system is properly filled with medium (see Proper use on page 11).
The following pre-commissioning checks must be performed:
•
Check that the HyCassette-Geko is correctly mounted on the ceiling.
•
Manually check the mounting of actuators.
•
Tighten all screw connections on medium connections.
•
Check all electric connections according to the available wiring diagrams and
all terminal connections for secure seating.
•
Proceed with commissioning (see chapter 7.2).
HAZARDOUS VOLTAGE!
Before performing any work on the unit, ensure that the unit is disconnected
and not under voltage. Ensure that the unit is properly secured against subse-
quent switch-on at an appropriate point of the on-site power supply.
DANGER OF SCALDING!
Before completing any kind of job on fan coil units:
Seal off the heating medium inlet before performing work on the valves or the
inlet or outlet pipes and secure this sealing from being opened unintentionally.
Do not commence work before the heating medium has cooled down.
RISK OF ROTATING COMPONENTS!
Rotating fan impeller wheel poses a risk of injury! Before performing any work
on the unit, ensure that the unit is disconnected and not under voltage. Ensure
that the unit is properly secured against subsequent switch-on at an appropriate
point of the on-site power supply.
NOTICE!
Prior to commissioning ensure that
–
the unit discharge (heat exchanger),
–
coil drip tray and suction area of the condensate pump
–
and filter are clean.
If necessary, these components must be cleaned or the filter replaced.
