1. Safety The following symbols mean: Caution: Read these operating instructions fully before use and pay particular attention to sections containing this symbol Caution: Surfaces can become hot during use. Always observe the following safety precautions Use only as specified by the operating instructions, or the intrinsic protection may be impaired. After transport or storage in humid conditions, dry out the unit before connecting it to the supply voltage.
To reduce the risk of eye injury during high temperature operation, use safety goggles or spectacles. Do not touch surfaces which become hot during high temperature operation. Allow the unit to cool down before moving it.
2. General Information The BTD is a digitally controlled dry block heater, with a unique circular block which can accommodate three sizes of microtubes. The BTD with it’s small footprint and powerful heater, for fast heat-up is ideally suited for many life science applications.
3. Getting started 3.1 Unpacking Remove packing materials carefully, and retain for future shipment or storage of the unit. 3.2 The BTD pack includes: » Block heater..........................................................................................1 piece » Mains cable...........................................................................................1 piece » Operating instructions (inc. CE certificate)............................................1 piece 3.
4. Operation of BTD 1 2 3 4 00:15 00:00 40.0 C 40.0 C You can accurately set the temperature and time required for your specific task by utilising controls 1 and 2 . In the following example we will assume that you wish to heat the microtubes to a temperature of 40°C for a time of 15 minutes. 4.1 Switch on the BTD. 4.2 Use the p and q buttons ( 1 ) to set the temperature to 40°C. 00:00 00:00 40.0 C 25.0 C 4.3 The BTD will now start to heat up to the set temperature of 40°C.
Continuous pressure on any of the p and q buttons will speed the display increments. Under the action of high temperature (> 85°C) tube caps can open, thus causing sample volume shrinkage or potential health risk when working with infected material. To prevent such cases it is recommended to use tubes with cap lock of Safe-Lock® type. 4.6 Select Run ( 3 ), the timer will begin, and the microtubes will be kept at 40°C for 15 minutes. 00:15 00:01 40.0 C 40.
5. Fault diagnosis SYMPTOM NO DISPLAY TEMPERATURE DOES NOT RISE WHEN EXPECTED TEMPERATURE CONTINUES TO RISE WHEN NOT EXPECTED Version 7 - May 2011 Page 10 POSSIBLE CAUSE ACTION REQUIRED Unit not switched on. Switch on. Unit not connected to power supply. Connect to power supply. Power supply failure. Check that other electrical appliances on the same circuit are working. Fuse blown in unit or plug (UK units only). Check and replace (see 6.2). Set temperature is lower than block temperature.
6. Maintenance Where applicable all Grant laboratory products are designed to comply with IEC61010-1 and can be flash tested. Some are fitted with radio frequency interference suppressers. Therefore it is recommended that only a D.C. test be performed. No other routine service is required. 6.1 Cleaning The cases can be cleaned with a damp cloth after disconnection. Do not use solvents.
7. Specifications The product is designed for operation indoors in a laboratory at altitudes up to 2000m and will meet the performance figures quoted within the ambient temperature range 10°C to 35°C, with maximum relative humidity of 80% and is safe for use in an ambient temperature up to 40°C. Installation category II (transient voltages). Pollution degree 2 in accordance with IEC 60664. For operation at altitudes of up to 2000 metres. Setting range .......................................................
8. Guarantee and Service 8.1 Guarantee When used in laboratory conditions and according to these working instructions, this product is guaranteed for TWO YEARS against faulty materials or workmanship. 8.2 Service For service, return for repair to our Service Department in the UK or, in other countries, to our distributor.
