IMPORTANT NOTE!
Danger of frost in cooling mode!
There is a risk of the heat exchanger freezing when used in unheated rooms.
Make sure that the unit is equipped with a frost protection sensor and/or thermostat in this case.
IMPORTANT NOTE!
Warning of misuse!
In the event of misuse, as itemised below, there is a danger of limited or failing operation of the unit. En-
sure that the airflow can circulate freely.
Never operate the unit in humid areas, such as swimming pools, wet areas etc.

1at LPHW 75 / 65 °C, tL1= 20°C, with fan-assisted convection
2The sound pressure level was calculated with an assumed room insulation of dB(A). This corresponds to a dis-
tance of m, a room volume of m³ and a reverberation time of s (in accordance with VDI 2081).
3Sound pressure level < 20 dB (A) and sound power level < 28 dB (A) outside the usual measuring and audible
range.
4at LPHW 167 / 149 °F, tL1 = 68 °F
5The sound pressure level was calculated with an assumed room insulation of 8 dB(A). This corresponds to a dis-
tance of 6.6 inches, a room volume of 3532 cft and a reverberation period of 0.5 s.

5.2 Brief description
Katherm QK are decentralised units for the heating of room air, for use in hotels, offices and business premises, among oth-
ers. Secondary air is drawn in by the fan and passed through the copper/aluminium heat exchanger. The temperature-con-
trolled air rises up the façade of the building to create a pleasant indoor climate.

6 Installation and wiring
6.1 Requirements governing the installation site
Only install and assemble the unit if the following conditions are met:
Make sure that the unit is securely suspended/standing.
Ensure that the airflow can circulate freely.
Provide adequate space for appropriately sized flow and return water connections on site (Connection to the pipe
network [}20]).
There is a power supply on site (Maximum electrical rating values [}24]).
If need be, provide a condensation connection with a sufficient gradient on site.
6.2 Installation
2 people are needed to install the unit.
CAUTION!
Risk of injury from sharp metal housing!
The inner metal of the casing can have sharp edges.
Wear suitable protective gloves.
IMPORTANT NOTE!
Horizontal installation of units!
When installing the units, ensure that they are completely horizontal to ensure proper operation.

Separately packed roll-up grilles, for instance when using installation covers to protect the trenches from dirt, are rolled up in
the factory. The grille can become slightly over-long due to the steel springs extending. Unrolling the grille and laying it flat
for a few hours can return the grille to its original length. Laying the grille into the trench helps it to fit more easily into the
frame.

6.2.2 Screed work
The following work needs to have been completed before screeding can begin:
Water has been correctly connected.
The electrical connections have been correctly wired.
The unit is correctly positioned and levelled.
There are no sound bridges to the concrete slab, especially in the area of the height adjustment feet.
Expansion joints have been provided on site to prevent the unit from being compressed by the floor or screed.
All the appropriate cable conduits have been laid.
Appropriate material has been used to seal all the openings and punched openings in the unit. They also need to be ad-
ditionally sealed when using floating screed or other low-viscosity floor coverings!
Cover the grille and floor trench with the transparent installation cover to protect the trench from dirt or cement.
