ASSEMBLY

Installation instructions – installation procedure
The first step is to measure and screw in the brackets. Floor-level brackets contain a transport stopper and bracket mount, that allows for easy and stable mounting of heat exchanger onto a bracket. Transport stopper prevents movement and damage to the heat exchanger during transport. Floor brackets can be measured according to the drilling templates included in the package. The heat exchanger is then mounted onto them and connected to the heating system. The heat exchangers must be bled. The last step is to fit the convector casing with the grille and attach it to the brackets. The grilles on Optimal, Power, Safe and Max free-standing convectors are removable for easier cleaning and maintenance. For more detailed information on each KORALINE type, please refer to the installation instructions. The units are supplied assembled, except for the brackets and mounts, valves and extension nipples, if applicable, which are included separately with the product.

KORALINE floor standing convectors are not intended for sitting or bearing weights. These activities can lead to damage to the device, reduce its efficiency and increase the risk of accidents. For safe and efficient heating, it is always necessary to ensure that the convector remains free and the exhaust cover is not covered.

BRACKETS AND MOUNTS

KORALINE free-standing convectors are fitted with floor-level brackets and some higher models also with wall fixing mounts as standard (see the Standard contents list at each model line). Sub-floor brackets and wall brackets are available upon request.

Floor-level brackets - fitted as standard

KORALINE free-standing convectors 2,000 mm in length and above are supplied with a central bracket for greater stability
For a correct installation of floor-level brackets it is necessary to use a transport stopper and bracket mount that also holds the heat exchanger in place during transport.

Floor-level brackets a contain transport stopper and bracket mount, that allows for easy and stable mounting of the heat exchanger onto a bracket.

Floor-level bracket height above floor level for all KORALINE models is 100 mm.

Floor-level bracket casing - optional accessory

Floor-level bracket casings are designed to cover connections and the edges of floor-level brackets, and must be ordered in pairs.

Sub-floor brackets - optional accessory

Convector lengths over 2000 mm – three brackets for increased stability are needed

Wall brackets - optional accessory

When mounting convectors on walls, the distance between the unit and the wall is 25–45 mm convector lengths over 2000 mm – three brackets for increased stability are needed.

Wall fixing mounts

Included as standard for higher convectors according to height of the respective model When mounting convectors on walls, the distance between the unit and the wall is 25–45 mm
