KORAFLEX Pool-V FVP

pool design

KORAFLEX Pool-V FVP heaters are suitable for heating humid environments (eg. swimming pools, conservatories, etc.). They are manufactured from AISI 316 stainless steel and are fitted with built-in drainage and dividing partition to protect against flooding. They are characterized by silent operation and can be connected to BMS (Building Management System). We recommend fitting an aluminium grille, and strict adherence to installation and operating guidelines. KORAFLEX Pool-V is finished with a hem, frams are not available.

EXCLUSIVE - RAL 9006 gray lacquered AL/Cu heat exchanger

Not suitable for installation in salt-water pools.

HEM FINISHING

KORAFLEX Pool-V FVP heaters are suitable for installation in humid environments. Fitted with built-in drainage and a sloping base. However, these convectors are not watertight and must not be flooded for long periods. For ideal operating conditions we recommend using water with a pH of 7.2 – 7.6, with a maximum chlorine content of 1 mg/l. Changes in these values – in particular lower pH values – will result in more aggressive water and corrosion of non-stainless steel components. Pool-V heaters installed in humid environments must be cleaned regularly with clean water and dried thoroughly. In case of visible calcareous deposits or oxidation, use a stainless steel cleaner followed by a suitable metal treatment product. For long-term satisfaction it is essential that basic maintenance of the stainless steel components is carried out. Further information can be found in the installation manual and Operating and warranty conditions, available to download on our website.

FV TRENCH HEATER INSTALLATION

Construction recommendations

To ensure correct operation, it is essential that the following principles are respected.

Trench heaters must be installed horizontally with the heat exchanger on the window side. For the grille to function correctly, the upper edge of the casing must be straight and level (not buckled or bent).
The maximum recommended distance of the trench heater from the wall/window is 100 mm.
The size of the trough in the floor for trench heater installation should be at least 100 mm bigger (both in length and width) than the convector.
We recommend connecting the trench heater to the heating system using a lockshield and thermostatic valve. The heat exchanger connection is by an inner G½ thread. Following connection to the heating system, bleed and carry out a pressure test.
When concreting, the trench heater must be levelled using the set screws provided and fastened to the floor using the anchors provided. The anchors keep the trench heater in place while pouring concrete.
Using anchors will extend the bottom width of the trench heater by 42 mm from each side.
While pouring concrete, the trench heater may be weighed down.
While pouring concrete it is important to brace the trench heater to prevent longitudinal buckling. Trench heaters are fitted with spacers for this purpose. Following concreting, these spacers are easily removed. Note: FVP models as standard are, however, not equipped with spacers.
While pouring concrete or anhydrite it is essential to seal all connection openings to prevent leakage. We also recommend insulating trench heaters against dampness.
Where trench heaters are not concreted in, raised floor support it is recommended to use. Standard models are not self-supporting.
We recommend insulating the outer side of the trench heater casing along the length of the heat exchanger with polystyrene to prevent heat loss into the floor.
For trench heaters with forced convection we recommend undertaking fastening and acoustic insulation by pouring thin concrete along the sides and under the base of the heater.
To avoid contaminating the trench heater, we recommend maintaining the protective hardboard cover in place during construction work. The cover, which is included in the standard contents, is not suitable for walking on and serves solely to protect the trench heater from contamination during installation. Strengthened OSB covers for installation purposes are available as optional extras.
KORAFLEX Variant F2V and F4V models with cooling and Pool-V FVP models installed in humid environments are equipped as standard with condensation drainage canals. The Variant F2V 11/20 and Pool-V models are fitted with drainage pipes facing the wall. During the installation of all models, the pipe at the bottom of the trench heaters must be connected to a pipe with sufficient gradient to drain overflow water and/or condensation. We recommend installing a U-bend to prevent odour.
The KORAFLEX Pool-V FVP model is suitable for use at swimming pools. The dividing partition is designed to catch water from the pool; however, it does not function as a standard swimming pool overflow. The partition is always situated closest to the pool. The heating part, including the heat exchanger and fan must be situated away from the pool. The Pool-V FVP model is equipped with two drainage pipes. The installation, operation and maintenance of this equipment requires special attention. Details can be found on web pages or in the installation instructions.
Fans are attached to the trench heater casing using magnets. For stainless steel models velcro is used. This system enables removal of the fans from the trench heater during installation to avoid damage, contamination, etc. Fans may also be removed this way for cleaning when the unit is switched off. With the exception of the Pool series, fans are installed to direct air towards the windows.
Electrical installation design must be carried out by suitably qualified persons in accordance with the relevant regulations.
Installation and servicing of the electrical installation must be carried out by persons with the relevant electro-technical qualifications.
Prior to commissioning, the electrical components must be thoroughly inspected in accordance with relevant regulations.
