INDICATIONS
The HOTLINE® Warmer is designed for use with the HOTLINE® Warming Set to warm blood and I.V. fluids and
deliver them to the patient's intravenous access site at normothermic temperatures under gravity flow conditions.
PRINCIPLES OF OPERATION
The HOTLINE® delivers fluids and blood at normothermic temperatures at routine, gravity flow rates. All other fluid
warming systems suffer from cool-down between the warmer and the patient connection. HOTLINE® overcomes this
problem by providing active warming of the patient line all the way to the patient connection, protecting the patient
fine against exposure to cold and eliminating patient line cool-down. Active warming is achieved by jacketing the
sterile
patient |.V. line with a layer of precisely temperature controlled circulating warm water. An 8' (2.4m) HOTLINE®
Warming Set allows blood and intravenous fluid to be delivered.to the patient at normothermic temperature at gravity
flow rates to 4,500 ml. per hour (83mL per minute).
The HOTLINE? Warmer and Warming Set are an integrated, highly effective design with unparalleled ease of use.
Properly trained users can confidently and safely have the HOTLINE® set-up and operating within seconds.
NOTE: The HOTLINE’ Warmer must be used only with HOTLINE Fluid Warming Sets.

DESCRIPTION
HOTLINE® WARMER:
An on board water supply is heated to 42°C and circulated through the HOTLINE® Warming Set. Electronic circuitry
continuously monitors the water temperature. Circulating water temperature and visual alarms are indicated on the
Display Panel on the front of the unit. A green “OPERATING” or “WARMING*" light illuminates on this panel when the
unit is set-up and operating correctly.
DISPLAY PANEL:
Five displays provide information for safe, convenient use of the device.

[HO
HOTLINE? WARMING SET:
Single Use HOTLINE® Warming Sets are provided in single unit packaging with Sterile Fiuid Path. The priming
volume of the warming set is 17.5 mL. A plug-in fitting on the HOTLINE® Warming Set engages a socket in the
HOTLINE® Warmer. This is the only connection necessary to provide the warming function. The HOTLINE® Warming
Set is easily unplugged from the HOTLINE® Warmer and discarded, or it may be used to continue subsequent
unwarmed infusion.
SAFETY
The HOTLINE® employs a safe, circulating water heating system, inherently free of “hot spots” to actively warm the
patient line. The primary temperature contro! circuit limits the circulating water to 42°C maximum. In the unlikely event
of a malfunction of this circuit, a second “watch-dog” circuit will visually and audibly alarm and stop the circulating water
pump if the temperature reaches 43°C. Fluid in the HOTLINE® Warming Set is never exposed fo any damaging or
dangerous temperatures while the unit is operating.
The HOTLINE® is manufactured to be in compliance with UL 2601-1 (HL-90 115V) and EN 60601-1 (HL-90 230V).
CONTRAINDICATIONS:
+ Not for use in warming cryo-precipitates or granulocyte suspensions.

WARNINGS:
Failure to follow warnings may result in patient injury or death.
The HOTLINE? Warming Set is a Single Use device and is not intended for resterilization.
Sterile Fluid Path. if caps are not in place, then sterility will be compromised.
Set-up, priming and use require aseptic technique. Follow applicable hospital policies and procedures.
Prime the circulating water path before connecting to the intravenous administration set. This is to
confirm that there is not a breach between the circulating water path and IV path. If fluid exits the
patient end before connecting to intravenous administration set, remove and replace administration set.
* All air must be removed from the intravenous fluid lines before connecting to the patient. Failure to do
so
may result in introduction of air to the patient, which may contribute to serious patient injury or death.
Monitor intravenous fluid fine to make sure it is air-free.
* Do not stick the HOTLINE® Warming Set tubing with needles, which will compromise integrity of the
patient intravenous line. If a disposable with a breached circulating water path/IV path is used, then
patient illness may occur because of the fluid warmer's circulating water entering the patient's blood
stream.
ㆍ. Do not use HOTLINE? in the presence of flammable anesthetics because of the risk of fire or possibility
of explosion.
« © Do not use HOTLINE" in high energy fields such as: MRI, X-Ray, etc. HOTLINE? may act as a projectile
in a strong magnetic field, cause image artifacts or not function as intended.
CAUTIONS: 」
・ Federal Law (USA) restricts sale of this device to or on the order of a physician.
* © Do not mount the HOTLINE? more than 42" (107cm) above the floor. For convenience 42" (107 cm) is
indicated on the HOTLINE" line power cord by a black mark. Mounting the HOTLINE“ above 42"
(107cm) may result in instability of the pole and tipping.
« Do not autoclave or immerse any part of the HOTLINE? in liquids, which may cause damage and
improper functioning.
¢ — Insure that the HOTLINE® pole clamp is screwed tightly onto the IV pole. Failure to securely mount the
HOTLINE? onto the IV pole may cause the HOTLINE? to slide down the IV pole.
+ Not for use with pressure devices generating over 300 mmHg. Pressure greater than 300 mmHg may
compromise the integrity of the HOTLINE® Warming Set.
NOTE: Hand pumps can generate over 1000 mmHg.
o
de
o.
ELECTRICAL SAFETY:
POWER REQUIREMENT
Most of the current drawn by the HOTLINES is for the 300-Watt immersion heater. When the device is first
turned on and the digital display shows rapidly rising temperatures below 41°C, the 300-Watt heater is in a
full ON condition. Beyond approximately 40°C, the proportional controller cycles the heater ON/OFF with
proportionally shorter ON times as the circulating water nears the 41.5°C set point.
ELECTRICAL SAFETY TESTING:
All testing and maintenance should be performed by qualified personnel. Safety testing is to be conducted
on an annual basis. This involves earth leakage and ground continuity, which must be tested according to
UL 2601-1 and EN 60601-1.
NOTE: This device is equipped with disposable sensing interlocks. A HOTLINE® Warming Set is
required to correctly operate the device and perform leakage current testing. Do not
defeat the disposable sensing interlocks or try to operate the HOTLINE without a
Warming Set in place.
Earth teakage must be tested according to UL 2601-1 and EN 60601-1. Earth leakage current test should
be performed with the immersion heater circuit in the full ON condition. For this reason, leakage current test
should be performed on a HOTLINE“ that has room temperature water in the water tank.
5

Ground continuity must be tested according to UL 2601-1 and EN 60601-1.
HOTLINE® is certified that it is in compliance with the European Communities Council Directive relating to
Electromagnetic Compatibility (EMC): (89/336/EEC). Test methods and acceptance criteria as specified in
EN 60601-1-2 demonstrate conformance.
STORAGE
Store in a cool dry place. Do not expose to extreme temperature. See Environmental Specifications for more details.

10. These suggested instructions are designed to be used in conjunction with established hospital procedures.
TESTING
All testing and maintenance should be performed by qualified personnel.
CAUTION: if any alarm conditions are not met remove the unit from service.
NOTE: Alarm testing requires a HOTLINE® Warming Set to be installed and the unit operating.
Alarm Test Switch: The HOTLINE® is equipped with two membrane switches on the side label. Pressing the
Alarm Test Switch activates all alarm conditions. Pressing and holding the Over Temp Test Switch activates the over
temp alarm condition.
To Test the HOTLINE® Alarm Circuitry:
Press the Alarm Test Switch.
Observe that the green LED goes out.
The three red LED's will light.
The audible alarm will sound.
Water will stop circulating. (This can be checked by observing the return port inside the water tank.) APRON

TEMPERATURE VERIFICATION
All testing and maintenance should be performed by qualified personnel.
Displayed Circulating Water Temperature: Should be verified using a Level 1 TEMP CHECK
Thermometer (HLTA-40). Other methods of temperature verification may be inaccurate. Units can be returned for
temperature verification.
Principles of Operation: The Circ. H,O is pumped from the water tank through the heater. The Circ. H,O then
passes the HOTLINE® thermistor, assembled within the heater on the output side, and then through the TEMP
CHECK. After this point the Circ. H¿O temperature begins to drop due to the effect of ambient temperature on the
disposable set. The temperature of the water tank is typically 0.5°C to 2.0°C lower than the temperature from
the heater. Verifying the operating temperature of the Circ. HO by temperature readings in the water tank will be
inaccurate. The TEMP CHECK senses the highest temperature of the Circ. H,O bath.
TEMP CHECK
REFER TO MANLIAL FOR CALIBRATION INSTRUCTIONS,
CAUTION: Refer to the TEMP CHECK HLTA-40 Thermometer Operator's Manual for complete Temperature
Verification and Calibration instructions.
SET-UP:
To set up the TEMP CHECK you will need the following:
*. TEMP CHECK (HLTA-40)
* HOTLINE? Warmer
ㆍ HOTLINE? Warming Set
1. Plug the HOTLINE® Warmer into power outlet.
2. Place the TEMP CHECK onto the top right corner of the HOTLINE® Warmer and plug it into the socket on
the right side of HOTLINE®.
3. Plug the Twin-Tube Connector on the HOTLINE® Warming Set onto the socket on the right side of the TEMP
CHECK,
4. Remove the black label from the auxiliary outlet on the back of the HOTLINE? and plug in the TEMP
CHECK power cord.
CAUTION: The auxiliary outlet is for use only with LEVEL 1 accessories.
5. Activate the Power Switch on the left side of HOTLINE®. Allow 15 minutes for the temperature to stabilize.
6. if the TEMP CHECK display indicates a temperature between 41°C and 42ºC, and the HOTLINE“ display
equals the TEMP CHECK display, water bath verification is complete. Refer to the TEMP CHECK Manual
for OVERTEMP ALARM verification.
7. If the TEMP CHECK display does not indicate a temperature between 41°C and 42°C, refer to the TEMP
CHECK Manual for calibration instructions.
