MN-38645 • Rev 1 • 04/18 • ivNow Fluid Warmer 7
Operation
General Information
The ivNow uid warmer quickly warms and maintains
the temperature of injection/intravenous solutions prior
to their use. The specially contoured warming module
cradles solution bags in 0.5-, 1-, 2- & 3-liter sizes. The
control can easily be set to display temperatures in Celsius
or Fahrenheit. A sensor in the heating plate detects the
presence of a bag and engages the heating mechanism
to quickly begin warming the uid. Two (2) temperature
sensors work in unison to precisely and continuously
read the temperature of the bag and another sensor
monitors the plate temperature. The heater will reengage
as necessary to maintain the temperature within +0/-2°C
(+0/-3ºF) of the setpoint. The electronic control monitors
the length of time the bag has been held at temperature,
beginning when the bag reaches setpoint temperature.
The display shows the time the uid has been held at
temperature.
NOTE: In the event that uid should spill inside the
cavity, unplug the unit to prevent an electrical
shock hazard. Wipe excess uid from module
immediately. Refer to qualied service personnel.
Qualied service personnel should remove the
module control and remove any remaining liquid.
Perform necessary hospital electrical safety checks
before returning the unit to operation.
ivNow Capacity Information
The ivNow warming module accommodates uids
packaged in bags. Each warming module cradles solution
bags in 0.5-, 1-, 2- and 3-liter sizes.
Safety Feature
• The control of the ivNow is designed to display an error
message (E-31) and stop heating if the temperature of
the uid bag (as monitored by the dual sensor switch)
is ever above 40°C (104°F).
• The control also monitors the temperature of the
aluminum and limits the temperature to a maximum of
60°C (140°F).
• There are two protective devices wired in series
with the heating element; an automatic thermostat
and a thermal fuse that disconnect the power to the
heating element if the plate exceeds 65°C (149°F) and
84ºC (183ºF) respectively, in the event of a run away
condition.

Operation
Operating Instructions
1. Before operating the module(s), clean the exterior of
the unit with a damp cloth and general hospital cleaner
(isopropyl alcohol).
2. Plug the appliance into an appropriate hospital-grade
receptacle. See the appliance data tag for voltage
requirements.
3. Turn ON by pressing the power button located
on the front of the warmer. When on, the
control display will be powered. The plate will
not heat until a bag is placed in module.
4. Activate control by placing bag of uid in module. See
Figure 1. For optimum performance, the bag should be
centered over the sensor.
NOTE: The warm-up stabilization time will vary slightly
depending on the bag temperature and ambient
room temperature.
5. The display will continue to show the current bag
temperature as the uid is heated.
6. The green status indicator will illuminate when the uid
is within +0/-2°C (+0/-3°F) of the setpoint temperature.
