Intended Use

WARMING CRADLE®should be used only as speciﬁed by Discovery

Laboratories, Inc. and is intended solely to warm contents of one or two

25-mm-diameter glass vials at a preset temperature of 44°C ± 1°C for

15 minutes. Discovery Laboratories, Inc. disclaims all liability for any misuse.

Safety Precautions

Although reasonable care has been used in the design and manufacture

of this product, Discovery Laboratories, Inc. has no control over conditions

under which this product is used.

•Connect WARMING CRADLE only to a properly grounded 110 V AC

electrical outlet

•Do Not use in an area where there is a concentration of ﬂammable vapors

•Do Not use in the presence of ﬂammable or combustible material, i.e.,

liquids with ﬂashpoints below 200°C

•Do Not warm substances that react violently when warmed

•Do Not spill liquids into the vial reservoirs or onto WARMING CRADLE

•Do Not shake or drop WARMING CRADLE

•Do Not touch hot surfaces (vial reservoirs) with bare hands

WARMING CRADLE is speciﬁcally designed to warm the contents

of one or two 25-mm-diameter glass vials at a preset temperature of

44°C ± 1°C for 15 minutes. Its features include:

• The capacity to warm two 25-mm-diameter vials independently

• A preheating cycle that raises the temperature of the vial reservoirs

to 44°C ±1°C

• A preset 15-minute timer that starts automatically when the vial

is inserted

• Dual temperature sensors to ensure that the correct temperature

is maintained

• A transparent, hinged dust cover that protects the vial reservoirs,

assists in warming, and helps keep the unit clean

• Audible signals that indicate:

– the unit is connected to the power supply

– the preset reservoir temperature of 44°C ± 1°C has been reached

– the vial has been warmed for 14 minutes

– the 15-minute warming cycle is complete

– removal of a vial prior to the completion of the warming cycle

– immediate service is required

• LCD and multicolor LEDs that provide information regarding status,

temperature, and time

• Temperature regulation to the preset temperature of 44°C ± 1°C

WARMING CRADLE®is designed to remain plugged in between

uses to maintain the preset temperature of 44°C ± 1°C and be ready to

use at all times.

Speciﬁcations

•Input voltage is 110 V AC, 50/60 Hz

•Input current is 0.75 A at 110 V AC

•Two 40 W heating elements are used for warming the vials

•The temperature is controlled to ± 1°C

•If the warming temperature is outside of the speciﬁed range, an audible

signal indicates that the unit requires immediate service

•Classiﬁcation according to UL61010-1 with regard to electrical safety:

– For indoor use only

– For use at altitudes up to 2000 meters

– Ambient temperature range is 5°C to 40°C

– Maximum relative humidity 80% for temperatures up to 31°C

– Humidity decreasing linearly to 50% relative humidity at 40°C

– Input voltage ﬂuctuations within ±10% of the nominal input voltage

– Transient Overvoltage Category II

– Pollution Degree 2

Quick-Start Guide to Operation

Follow these simple steps to operate

WARMING CRADLE®Dry Block Heater 801-000.

Remove WARMING CRADLE and power cord from the box.

Insert power cord into WARMING CRADLE and plug

WARMING CRADLE into a 110 V AC electrical outlet.

•Listen for 3 short beeps

•Look for ﬂashing AMBER LEDs

•Check that the display alternates between “Preheating” and “In Process”

Verify that WARMING CRADLE has reached the

operating temperature of 44ºC ± 1ºC.

•Listen for 3 short beeps

•Look for steady GREEN LEDs

•Check that the display alternates between “Insert” and “Vial”

When Step 3 is completed, WARMING CRADLE is preheated and ready to

warm vials. The unit should remain plugged in between uses to maintain the

preset temperature of 44°C ± 1°C and be ready to use at all times.

Open the dust cover and insert vial(s).

•Look for alternating AMBER and GREEN LEDs

•Check that the display alternates between “Warming” and “Vial”

Note:

– The factory preset time is 15 minutes

– The “Warming Vial” cycle will run the full 15 minutes, irrespective of the vial

starting temperature

– WARMING CRADLE automatically detects when a vial is inserted

and will start the timer on the display

– The temperature may brieﬂy drop 2°C to 3°C when a cold vial

is inserted

– After 14 minutes of warming, a 2-tone signal will sound once, to let

you know that the warming cycle is almost complete

At 15 minutes, verify that the warming cycle is complete.

•Listen for a 2-tone signal that sounds repeatedly

•Look for ﬂashing GREEN LEDs

•Check that the display is ﬂashing “Complete”

Remove the vial(s).

CAUTION:

If a vial is removed prior to completion of the 15-minute warming cycle,

WARMING CRADLE®will sound a continuous tone and the display

will alternate between “Replace” and “Vial.” The LED(s) will ﬂash RED.

If the vial is replaced within 10 seconds, the continuous tone will stop

and the timer will continue. If the vial is not replaced within 10 seconds,

the continuous tone will stop, the timer will reset to 0:00, and WARM-

ING CRADLE will return to the ”Insert Vial” mode.

The 2 vial reservoirs operate independently. If there are vials in

both of the vial reservoirs, and the timer resets to 0:00 for one of

the 2 vial reservoirs, as described above, the 2-tone signal that

sounds after 14 minutes has elapsed will only be for the vial that

has not had an interruption in the warming cycle.

NOTES:

•WARMING CRADLE requires preheating each time it is plugged

into a 110 V AC electrical outlet

•WARMING CRADLE should remain plugged in when not in use

•If no vial is inserted, WARMING CRADLE:

– will remain heated at 44°C ± 1°C indeﬁnitely

– display will continue to alternate between “Insert” and “Vial”

•When a vial is removed, the display will return to alternating between

“Insert” and “Vial,” and the timer will reset to 0:00

•If a vial is not removed after the 15-minute warming cycle, the timer

will continue to track the elapsed time and maintain a temperature of

44°C ± 1°C. The 2-tone signal will continue to sound repeatedly, as a

reminder that the warming cycle is complete and that the vial should

be removed

•If 2 vials have completed the 15-minute warming cycle but only 1 vial

is removed, the 2-tone signal will continue to sound repeatedly until

the second vial is removed

•There is no auto shut-off feature or on/off switch
