Page 3: Device Description
Device description The Otoflash G171 is a light-induced polymerization device for the curing of light-curable resins in laboratories, research facilities, training centers, commercial premises. There are 2 bottom-mounted flash-lamps, operating at a frequency of 10 flashes per second. Compared to polymerisation through continuous exposure, the curing by means of light flashes has the following advantages: 1. -

Page 8: Operation
Operati on Setti ng the ti mer (Figure 1) The device is switched on with the main switch (1). The green light indicator labelled “Ready” (7) will light up and 4-digit fi gure will appear on the display (4). This fi gure indicates the number of fl ashes. The number of fl ashes can be programmed any number between 0 and 9999 by pressing the butt ons 1000, 100, 10 and 1. - Page 9 Maintenance, cleaning, repair (Fig. 3) ▪ Air fi lter The fi lter fl eece (Fig.3/A), located directly behind the display (accessible when the lid is open), should be carefully blown out by means of compressed air and replaced at least every 6 months. ▪...
- Page 10 DANGER Before carrying out any service or maintenance work, the device should be disconnected from the power supply. – The fl ash-bulbs can only be replaced by replacing the enti re fl ash-module. Danger due to hot surface – Allow hot fl ash-module to cool off by running the device in stand-by mode for approximately 1 minute.
- Page 11 Transport, storing, operation, disposal The following conditions apply for transportation or storage of the device for up to 6 months: Temperature: 0°C - +70°C Relative humidity: 10% - 80% After this, the following operating conditions apply: Temperature: + 10°C - +40°C Relative humidity: 10% - 80% The device must be stored and operated in closed rooms only.
- Page 12 10 Protecti ve gas (preferably nitrogen N2) With use of the protecti ve gas, oxygen is displaced from the polymerisati on chamber. This prevents oxygen inhibiti on, allowing workpieces to cure without an inhibiti on/adhesive residue layer at the surface (see point 3 in Secti on 1 – Device descripti on). The following components are included in models with the protecti ve gas opti on: A quick coupling socket with (nominal diameter of 7.2 mm), located at the back of the device, for connecti on to a gas cylinder (Fig.

(e.g. 3.0 at 99.9% or 5.0 at 99.999% purity) is recommended as protective gas for this device. Contact the device manufacturer NK-Optik GmbH before you intend to use any alternative inert gases (e.g. Argon or CO2) for the protective gas function, as this will require the use of specialized tray inserts. - Page 14 – connecting tube, inner diameter Ø 6 mm with quick coupling W 7,2 mm – Flashmeter® G401, measuring device for measuring of light intensity within polymerisation chamber NK-Optik GmbH Isarstrasse 2 82065 Baierbrunn Germany Phone: +49 (0) 89 744 145 - 0 Fax:...
