1-9
4.3 Turning the unit on
Connect the power cable of the Test Tube Heater to the K-APS-300 power supply.
The amber indicator light (3) will glow and a short single tone will sound when the power supply is
turned on.
4.4 Initial heating of the unit
1. When the power supply has been turned on, the amber indicator light (3) will glow continuously, if
the unit is not already heated to the operating temperature.
NOTE:
If beginning at ambient room temperature the unit takes approximately five minutes to heat up to
the optimal operating temperature. During this time the amber indicator light (3) will glow continuously.
2. When the unit has reached the set operating temperature the amber indicator light (3) will begin to
flash slowly. The unit is now ready to be used.
3. Throughout the use of the unit the operating temperature will be thermostatically maintained.
4. If the output voltage of the power supply is inadequate, an audible tone will sound indicating that
the device may not be able to maintain the set temperature.
4.5 Placement of test tubes
5. The Test Tube Heater has been designed to accept Falcon® 2001 Series test tubes. Any number, up to
six, can be used at the same time.
6. All test tubes should be placed in the test tube heating compartments (2) through the openings in
the top of the unit. The test tube should fit snug in the appropriate test tube heating compartment
(2) without using excessive force.
7. No lubricant should be used on the outside of the test tube or in the heating compartment (2).
4.6 Turning the unit off
8. When the power supply to the Test Tube Heater is disconnected, the amber indicator light (3) will
turn off. A single audible tone will also sound to alert the user to power disconnection.
5. Alarm conditions
The Test Tube Heater uses both audible and visual indicators for a variety of conditions.
5.1 Unit insufficiently heated
When the unit is “ON” but not at the operating temperature the amber indicator light (3) will glow
continuously. The unit should not be used when in this condition.
5.2 Unit at operating temperature
When the unit has reached its operating temperature (within approx. 1°C) the amber indicator light (3)
will begin to flash slowly. The unit should only be used when in this condition.
5.3 Overheating Alarm
If the temperature of the unit exceeds the preset temperature a secondary safety circuit will be activated
preventing overheating of the test tube contents. In this alarm condition:
• The amber indicator light will turn off and no further heating of the unit will occur.
• A continuous audible tone will sound until the temperature drops to preset temperature.
Note: If the ambient temperature of the environment is high, the overheating alarm may activate.
The unit will not commence heating until the ambient temperature falls below the preset temperature.
The overheating alarm will activate again when the temperature of the unit exceeds the preset
temperature. This cycle will be repeated as long as the ambient temperature remains high.
