Maintenance and Troubleshooting

8.1

Maintenance

The HyCassette-Geko unit is a high-quality, reliable unit. In order to guarantee the 
durability and trouble-free performance of the HyCassette-Geko unit, regular 
maintenance and inspection must be performed by technical experts.

NOTICE!

In the maintenance and cleaning work described below, a distinction is made 
between two qualification levels. Certain regular cleaning procedures cited un-
der Chapter 8.3 may only be performed by an instructed cleaning crew, as long 
as the following safety guidelines are ensured by qualified and licensed staff, 
such as a building technician with appropriate training / qualification. Every  
technical maintenance according Chapter 8.2, as well as the inspection and 
cleaning of the SWIRL® cover according to Chapter 8.3 may only be performed 
by qualified licensed staff. Always observe stipulations of the operation manual 
as well as all applicable valid regulations. 

RISK OF ROTATING COMPONENTS!

Danger of injury from rotating fan wheel
Before performing any work on the unit, ensure that the unit is de-energized. 
Ensure that the unit is properly secured against subsequent switch-on at an ap-
propriate 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/outlet pipes and secure this sealing from being opened unintentionally.
Do not commence work before the heating medium has cooled down.

HAZARDOUS VOLTAGE!

Power the unit down before carrying out any kind of work that involves remov-
ing any covers. Ensure that the unit is properly secured against subsequent 
switch-on at an appropriate point of the on-site power supply.

NOTICE!

The manufacturer’s warranty will become void if unit damage is attributed to 
failure to perform regular maintenance and inspections.
