PRODUCT INFORMATION

Tanning and relax appliance HB955 is equipped with a universal power PCB.

This means that the speciﬁ c characteristics of the appliance have to be programmed in a microcontroller to determine the way in which various components are activated.

When the mains plug is inserted into the wall socket, the display of the remote control will show all functions available to the user.

Including the various combinations, these functions are:

time setting full body tanning

half body tanning relax session UV working hours

The UV lamps may produce a humming sound just after start-up. This humming sound will stop as soon as the lamps burn properly, which is after about 20 seconds. At this point the light intensity clearly increases.

During the last minute of the session the beeper produces an intermittent signal to alert the user to the fact that a new session can be set.

After pressing the key, the display showing and , the UV working hours will be shown. After 750 operating hours, an L will automatically appear on the display to indicate that the HPA lamps need to be replaced or the tanning time must be slightly increased.

The clock speed of the µ-controller is derived from the 50 Hz mains frequency.

This frequency is also used to control the 8 triacs that determine the switch-in point (soft start) of the cos ϕ capacitors and the HPA lamps.

The fans are switched via the safety relay. This relay is part of the (one fault condition) timer circuit. If the control of the triacs is disturbed due to a fault in the

µ-controller, the UV lamps may not be switched off. As the µ-controller also generates a pulsating direct voltage

to power the relay, the relay will be de-energised in case of a fault, thereby interrupting the lamp circuit.

Conversely, the appliance will not start if the switch contacts of the relay are closed at that moment (sticking contacts).

The remote control is galvanically isolated from the mains, with power supply and control taking place via a 4-core cable.

The remote control only functions as input/output terminal.

The IR lamps are started by means of the conventional phase cut-in principle and burn at full power after about 8 seconds.

DISASSEMBLY AND ASSEMBLY + REPAIR INSTRUCTION

HB955/A

1. FLOOR PART (item 48)

- Remove the props (item 44) in the grip.

- Remove the covers (item 33 and 45). The cover on the flex side can only be removed last.

2. REMOTE CONTROL (item 31)

- Detach the cord clamp at the back of the cord holder and pull the connector loose.

3. WHEEL (item 36)

- Remove the covers (item 33 and 45).

- Remove the locking plate and the nearest frame screw.

- Push the shaft out of its clamping.

4. STAND LOWER PART (item 28)

- Put the appliance in the lowest operating position (however, screw (A) must be visible) and tighten the ornamental screw (item 27)

- Remove the covers from the floor part.

- Detach the 8-core cable so that the cable can easily slide through the cable duct.

- Remove the shafts (B).

- Remove the 2 bearing bushes (item 29).

- Pull the 8-core cable out of the stand tube to the point where the clamped joint between the cable bushing and the protecting sleeve can be unlocked.

- Detach the 8-core cable by loosening the nut of the bushing a quarter turn.

- Now turn the stand and the radiation units through so far that the covers (item 15/17) rest on the floor.

- Remove screws (A) and separate the upper and lower part of the stand.

5. STAND UPPER PART (item 23)

- Loosen the lower part of the stand as described under .4.

- Hinge the radiation units outwards (the upper part of the stand rests on the floor).

- Remove the housing parts and detach the wire connections.

- The covers (item 15/17) can now be separated from the hinge part.

WHEN A HOUSING AND COVER ARE ASSEMBLED, SPECIAL ATTENTION SHOULD BE PAID TO THE POSITIONING OF THE UPPER BEARING BUSH (see exploded view).

NB: When checking or replacing lamps, pay attention to

the following:

a. HPA lamps only start burning when they have cooled

down sufficiently.

b. Never touch a lamp with your fingers. Clean the lamp

with a cloth moistened with alcohol, if necessary.

c. After assembly the glass filter should be free from finger

prints and dust. Clean the glass filter with a cloth moistened with alcohol, if necessary.

d. New HPA lamps may show colour differences. This is

not a defect, but a characteristic phenomenon of lamps of this type. The discolourations disappear after a short period of use.

e. Always use protecting goggles when looking in the

direction of burning lamps.

7. GAS SPRING (item 18)

- Let the radiation part slowly rise from its transport position.

- Hinge the radiation units outwards and remove a decorative cap and spring fix at C.

- Now push the radiation part back into transport position.

- Use a plastic hammer to tap the pin at C outwards.

NB: CONTINUE TO EXERT PRESSURE ON THE

STAND.

- Hinge the radiation units inwards again and raise the stand slowly by means of the handle.

- Now turn the stand and the radiation part through so far that the radiation units rest on the floor.

- The gas spring is now unloaded so that pin (D) can be easily removed.

- Assemble the new gas spring, the protecting bracket and cover and press the pin (D) back in place again.

- Lift the radiation part by its handle and check whether the gas spring with pin (E) is correctly supported in the fork of the hinged part.

- Press the hinged part against the spring pressure, moving the radiation part along at the same time until the whole unit is in horizontal position again.

- Continue to exert pressure and hinge the radiation units outwards.

- Assemble the pin at C.

- Put the appliance in operating position, and assemble the remaining clamps.

6. HPA and IR LAMP (item 6 and 7)

- Put the appliance in operating position.

- Remove the 6 screws from the lamp unit in question.

- Remove the cover (item 15 or 17).

- Remove 4 reflector clamps.

- Remove the reflector and take the lamp from the holder.

8. POWER PCB (item 34)

- Pull the mains plug out of the wall socket.

- Remove the cover (item 33, see under .1).

- Replace the power PCB and connect all connectors.

- Place the cover on the base. The display of the remote control will now show error code E06 or E05.

- This indicates that the power PCB still needs to be programmed (code A05) for use in the HB955 according to the input in the table.
