4. On each lamp there are two clear plastic clasps that hold the lamps in position. To
remove them position both thumbs on the top of the clasp and use your index fingers to
pull the sides of the clasp outward until it releases, and the clasp can be removed.
5. On top of each lamp socket there will be a red button that, when pushed, will allow you
to remove the base of the lamp from its corresponding lamp socket. With one hand firmly
press and hold the red button down. While holding the red button down, use your other
hand to carefully lift the lamp up and out of the socket.
6. With one hand near the base of the lamp and the other at the opposite end, grasp the lamp
and pull both ends upward at the same time until it clears both clasps and the lamp
holder/socket.
7. To replace the lamp simply reverse the removal process.
8. To replace the hood lamps simply turn the hood upside down, this will expose the hood
lamps, and repeat steps 5-8.
Note: Please see section 10.0 Lamp Inspection on page 12, for the correct specifications of
replacement lamps and the Maintenance section for instructions on how to reset the lamp age
monitor.
24.0 4 Series Information
24.1 Electrical Requirements
Daavlin offers the 4 Series Phototherapy equipment with either 10 or 20 lamps. Units can be
equipped with UVA, UVA-1, Blue Light, Narrowband UVB, and Broadband UVB lamps. While
the type of ultraviolet lamp (UVA, UVB, or Blue) does not influence the electrical requirements,
the number of lamps contained in a unit does determine the amperage necessary to safely support
operation. The table and diagrams below define these requirements for each model variations.
All domestic 100/120-volt 60 hertz models require a grounded, three prong electrical outlet rated
for at least 15 amps and comes equipped with a grounded, three prong plug. Units designed for
other voltages may be shipped with no wall plug, which would then have to be locally obtained,
and require an appropriate outlet that must be installed to meet local standards and requirements.
All power cords must be an approved hospital grade cord rated 300V, 1.5mm
2
minimum. The
power cord is the main disconnect device. Each unit is equipped with an IEC 320 style power
inlet, which incorporates two, 5x20mm fuses.
Note: This unit should be on a dedicated circuit.
