Service Manual

PRODUCT INFORMATION

- This full-body tanning appliance is equipped with an
electromechanical timer connected to an electronic
watchdog that immediately switches off the appliance
in case the timer is defective. This watchdog consists of
a PCB attached to the rear of he timer housing and also
gives a signal when the last minute of the set time has
been reached.

- 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 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’.
