Thermor Rafale ACI+ - Manual (Page 13)

WARNING : This device is not intended for use by persons (including children) with physical, sensory or mental disability, or by persons lacking experience or knowledge, unless they have received from a person in
charge of their safety adequate supervision or preliminary instructions on how to use the device.
Care must be taken at all times to keep children from playing with the device.
Important: The applicable national standards must be observed when installing the water heater . If you judge that you do not have sufficient expert knowledge to install this product correctly, you are
advised to consult a professional.
LOCATION
Caution : Heavy items – handle with care.
1°) Install the appliance in a room which is protected from frost. If the appliance is damaged because the safety device has been tampered with, it is not covered by the guarantee
2°) Make sure that the wall on which the appliance is mounted can support the weight of the appliance when filled with water
3°) If the appliance is to be fitted in a room or location where the ambient temperature is higher than 35°C, ventilation must be provided in the room
4°) When installed in a bathroom, do not install the appliance in volumes V0 and V1 (see fig 1). If the water heater is to be installed above habitable rooms, fit a retaining tank with drainage to the sewerage system.
5°) Position the appliance where it can be accessed.
INSTALLATION OF A VERTICAL WALL-MOUNTED APPLIANCE: To enable the heating element to be replaced, leave free space below the ends of the tubes of the appliance. Small appliance: (see fig
2/3) ; Ø 438 range ( see fig 4); Ø 505 range: (See fig 5 ). Ø 505 appliances can be mounted on a tripod (optional) if the wall is not strong enough. It is, however, obligatory for the upper bracket of the
water heater to be attached to the wall to prevent it tilting.
INSTALLATION OF A STABLE WATER HEATER The water heater must be installed absolutely vertically in such a way as to ensure perfect stability with access to its electrical parts and safety devices.
Allow for access to parts which may need replacing.
INSTALLATION OF A HORIZONTAL WATER HEATER: PC 30 and 50 l(Ø 338) Range: (see fig 6) ; Ø 433 range: (see fig 7) ; Ø 505 Range Various ways to install (see fig 8); when the water heater is
in place, the water connections MUST be absolutely vertical below the appliance. Allow for access to parts which may need replacing.
WATER CONNECTIONS
All water supply pipes must be thoroughly cleaned before connection. The connection to the hot water outlet must be made using a cast iron or steel sleeve or a dielectric union in order to avoid corrosion of the
tubes (due to direct contact between iron and copper). A brass union must not be used.
UNVENTED INSTALLATION: A new safety device which conforms to current standards (in Europe EN 1487) MUST be fitted. The safety valve must be protected from frost. No water accessory must be
located between the safety device and the cold water inlet to the appliance. A pressure reducer (not supplied) is required when the water supply pressure exceeds 5 bar. Connect the safety device to an outlet pipe to
drain off the heat-expanded water or to allow for drainage of the water heater. Pipes used must be capable of withstanding a temperature of 100 °C and a pressure of 10 bar (see fig 9 )
VENTED INSTALLATION: (Supply for a single water drawing point). The installation must be equipped with a special mixer tap (not supplied).
Attention : each time the unit heats up, water will flow from the tap. Do not block this flow. (see fig 10 )
If using PER pipes, we strongly recommend that a thermostatic regulator be fitted to the water heater outlet. It will be set according to the performances of the equipment used.
ELECTRICAL CONNECTIONS (table of diagrams. Refer to the relevant diagrams)
The water heater can be connected and powered only by a single-phase 220/240 V AC or a three-phase 400 V mains supply according to model. Connect the water heater via a fixed duct with a cross section of 2.5
mm
2 (4 mm 2 for power supply > 3700 W). Use a standard duct (fixed or ring reinforced sheath) to the calibrated receptacle in the caver. In the case of appliances fitted with a cable or a plug (not allowed in France),
connect up directly. The earthing conductor on the cable MUST be earthed or the wire must be earthed using the spike (shown by the symbol . ). This connection is a vital safety feature. The green-yellow earth
wire must be longer than the phase wires. The installation must be equipped, upstream of the appliance, with a bipolar cut-out device (contact opening at least 3 mm ; fuse, breaker switch.) If the ducts are made of
insulating material, the electrical contacts must be protected by a 30 mA earth-leakage breaker conforming to the applicable standards. Adapt the connection to the power supply (see diagrams and table).
Before removing the cover, switch off the power.
Thermal circuit breaker: All our products are equipped with a thermal circuit breaker with manual resetting which shuts off the power to the water heater if it becomes overheated.
Attention: If the circuit breaker keeps tripping. a) switch off the power before taking any further action, b) remove the caver, c) check the electrical connections, d) reset the thermal circuit breaker. If
the circuit breaker continues to trip, replace the thermostat. Never by-pass the safety device or the thermostat. Connect the power supply only via the terminal.
COMMISSIONING/USE
ATTENTION : Never switch the water heater on without it being filled with water. Before switching on, open the hot water taps, bleed the pipes until no air is present and fill the appliance.
Check that the pipes and the door seal under the caver are not leaking. If there are any leaks tighten gently. Check that the water safety devices are working and fill the appliance. Switch on the appliance. After 5 to
20 minutes according to the capacity of the appliance, water should start dripping from the drain outlet. This is normal and results from the expansion of the water. Check that joints and seals are watertight. In the
course of heating up, shielded water heaters may make a boiling noise ; this is normal and does not indicate any fault with the appliance.
To avoid the development of bacteria (legionella…) ensure that a temperature of 60°C is reached every day. The thermostat is set at the factory at (65°C+- 5°C. or 82+-3°C according to model). IMPORTANT: If
steam or boiling water emerges continuously from the drain plug or drain tap, switch off the electricity and call a professional.
MAINTENANCE
User maintenance: operate the drain valve on the safety device once a month. If this is not done, damage may be caused and the guarantee invalidated.
Maintenance by a qualified person:
a) Remove the scale sludge. Do not scrape or chip at lime scale deposited on the casing because this may damage the lining
