- This full-body tanning appliance is equipped with an
electronic power supply. This means that when the
appliance is connected to the mains, the tanning or
relaxing functions are made visible by means of symbols
on the display. The set time is also shown on the display.
During the last minute of the set time, an accoustic
signal sounds.
- The UV lamps only burn in combination with the IR
(relax) lamps. When the UV lamps are on the IR lamps
burn at reduced intensity.
- The IR lamps can also be used separately at full intensity
for a relax session.
- This appliance is equipped with a sound module,
offering a selection of four nature sounds. The user can
also connect an external music appliance to play his/her
own music, either via the loudspeakers or the earphones.
- This tanning appliance has also been fitted with a scent
unit. The scent granules required for this unit can be
ordered as service part (see parts list).
IMPORTANT
- Because of the brief high starting voltage, the appliance
should be connected to a circuit protected with a 16A fuse.
- HPA lamps only go on at a restart if they have cooled down
sufficiently.
- Never touch the HPA lamps with your fingers. If necessary,
clean the lamps with a cloth moistened with some alcohol.
- When a new HPA lamp is installed, this lamp may have
a different colour compared to the other lamp. This is
normal and will disappear after a short period of use.
- After repair, the glass filters should be free from fingerprints.
If necessary clean the filters with some alcohol.
- Never look directly into the light of an HPA lamp when it
is on without protective goggles.
- Insufficient cooling – for instance when the vents are
blocked or when the fan has broken down – will cause the
thermal safety cut-out to switch the appliance off. Once the
cause of overheating has been removed and the appliance
has cooled down sufficiently, it will switch automatically on
again.
- Let the appliance cool down for 15 minutes before folding
it back into transport position and storing it.
- Only move the appliance when it is in transport position,
i.e. when it is folded.
- If there are complaints about inadequate tanning, the
output of the lamps can be measured with a UV-X 36
meter. For the minimum values, see table under ‘Technical
information’.

TECHNICAL INFORMATION
To replace the hinge housing assy:
- Undo the screws of the main grip.
- Take the main grip off stand.
- Remove the black plastic tube from the column.
- Slide the lamp housing together with the slider off the
column.
To replace the paw and the paw cap (L&R) and the wheels:
- Undo the screw on the inside of the paw.
- Unsnap the paw caps.
- The wheels are now accessible.
- Undo 4 screws in the point of rotation of the paw to detach
the paw.
To replace the sliding plug leg:
- To replace the sliding plug of the leg, the existing sliding
plug has to be smashed with the pointed end of a hammer;
otherwise it can’t be removed without damaging the leg. A
new sliding plug can simply be snapped onto the leg.
6. Resetting the timer and hour counter
- When the timer has detected a “temporary” fault, it shows
an error code on the display.
- If the error code does not disappear, there is probably a
defect in the relay board or the checking device in the
software.
- Reset the hour counter (e.g. after replacing the UV lamps).
Always unplug the appliance before disassembly or repair!
1. Replacing lamps, fans and starters.
- Fold the appliance out into operating position.
- Remove 12 screws on the bottom of the lamp housing.
- Remove the upper part of the lamp housing
(the fans, starters and internal wiring are now accessible)
- Remove the screws of the mounting bridge.
- Remove the reflector clamps.
- Remove the reflector.
You have to lift the mounting bridge to do so.
2. Replacing lock grips, soundboard, relay board and power
SMPS (PCB)
- Remove the back of the timer housing.
- Now the lock grips, sound board, relay board and the power
SMPS are accessible
3. Replacing timer front with speakers and display
- Remove the grip main assy and slide the lamp housing
together with the slider off the column and place it on a table
or bed with the front pointing downwards.
- Remove the back of the timer housing.
- Remove the sound board, the relay board and the power
SMPS and undo the plug-in connections.
- Undo the 4 screws attaching the front to the black sleeve.
- Now the front can be removed.
4. Replacing seesaws (always replace both)
- Start disassembling the appliance as described under 3.
- Remove the back of the timer housing.
- Remove the 4 screws attaching the front to the black sleeve.
- Remove the black sleeve.
- Remove 2 shafts.

a hydraulic press and cannot be removed without causing
serious damage.
- As a result, the hinge housing cannot be disassembled either.
- The legs have been mounted on the paw by means of a
hydraulic press and cannot be removed without causing
serious damage.

As a result of an intermitting contact, the text ERROR may appear on the display when the appliance is plugged in and switched on
(only occurs in HB935/A up to production code 0442).
This can be solved by assembling an extra PCB (item 49) according to the diagram shown on page 4 of the service manual and by
removing two “ground loops” according to de instructions on page 10.
Customers who have an HB935/B and complain about a hum or bleep: exchange the Error Fix PCB (item 49) fore one with a
resistance in the yellow wire and cut the “ground loops” according page 10.
If this gives problems because it does not fit, you have to change item 14 complete!
After assemble the Error Fix PCB, always reset the timer.
Check if the PCB has been correctly assembled: the display turns black immediately after the plug is pulled out of the socket.
- Drawing to explain where the extra PCB should be
assembled.
ERROR in the display and/or hum or bleep on the headphone
Procedure after removal of the back of the timer housing:
- Connect red/black wire to Error Fix PCB at “SMPS”.
- Disconnect red/black wire from the soundboard (1) and connect it to the Error Fix PCB at “UP” (2).
- Connect the yellow/black wire of the Error Fix PCB to the vacant connection of the sound PCB (3).

- Pull the plug with the red/black wire out of the power supply PCB (1) (this socket remains vacant and the wire should be fixed
in the bunch of wires).
- Plug the red/black wire of the Error Fix PCB into the power supply PCB (2).
- Put the red and blue wires across the connector block of the
mains cord, turn the Error Fix PCB upside down and fasten
it in the vacant spot with double-sided adhesive tape (first
remove the backing).
- Then connect the brown and blue wire of the Error Fix
PCB in parallel to the mains cord connector.
- Loop the wires and fasten them with the tie wrap
supplied (1).
- Tie the blue and brown wires to the mains cord with a tie
wrap (2).
