EnteraLite®Infinity™Operator’s Manual © Copyright 2004 ZEVEX Incorporated
43
WARNINGS
Use ONLY feeding solutions prescribed by the responsible physician, regis-
tered dietitian, registered nurse, or other licensed practitioner.
Use ONLY EnteraLite®Infinity™Disposable Sets to ensure proper fluid deliv-
ery. Others will not deliver the correct dose, may allow dangerous free-flow
conditions, and may generate hazardous fluid pressures which may activate
occlusion alarms at unpredictable pressures.
Low flow rates, combined with high dose settings may exceed the life of the
disposable set. The disposable set must be replaced every 24 hours to main-
tain delivery accuracy, allow proper air and occlusion sensing, and prevent
growth of bacteria. DO NOT PROGRAM RATE AND DOSE COMBINATIONS WHICH
EXCEED A 24 HOUR FEED REGIMEN.
The battery capacity is an approximation. If you are unsure that enough
capacity remains for your intended use, recharge it.
To avoid electrical shock, never clean pump with charger plugged into an
outlet or when pump is on.
Do not use EnteraLite®Infinity™Enteral Feeding Pump for delivery of non-
enteral solutions. Serious injury may result.
Proper operation of pump requires door is closed and latched. Make sure
door is closed and latched when motor is running.

Total Volume may be incorrect due to an interruption of battery power if the
overcurrent or temperature protection circuits are triggered. In such a case
one of the following conditions occurs:
During Single Feeding: Pump enters pause mode, but does not dis-
play “DOSE DONE” or turns off (but not due to a low battery).
During Interval Feeding: Pump enters pause mode or turns off (but
not due to low battery).
CAUTIONS
Federal law (U.S.A.) restricts this device to sale by or on the order of a
physician, registered dietitian, registered nurse, or other licensed practi-
tioner.
Dispose of EnteraLite®Infinity™Disposable Sets properly, as required by
local law.
If any leaks are detected in the disposable set, stop pump operation and
disconnect set from patient and replace with a new disposable set.
Care should be used when manually priming delivery set to ensure cassette
is not damaged by excess force.

8. Additional Technical Information
Operational Conditions
EnteraLite®Infinity™is designed in accordance with EN 60601-1-2, EN
60601-1-4, and RTCA DO-160D standards for electromagnetic emissions and
immunity. Normal operation should not interfere with nor be affected by
other electronic equipment. EnteraLite®Infinity™can safely be operated on
commercial aircraft.
EnteraLite® Infinity™ Disposable Set Displacement
EnteraLite®Infinity™Disposable Set displaces approximately 15ml of fluid
when primed. Approximately 3.5 ml of air is drawn into the tubing before
the enteral pump detects that bag is empty. Therefore, approximately 11.5
ml of fluid remains in the disposable set when the pump stops feeding.
(These values vary by approximately 0.5 ml, depending on whether battery
is low or fully charged).
Routine Maintenance
There are no user serviceable parts or routine calibration or adjustment pro-
cedures required for EnteraLite®Infinity™. All service requests should be
referred to ZEVEX technical service.

7. Important Pediatric Considerations
Occlusion alarm pressure of EnteraLite®Infinity™is 5 psi (34kPa) for
upstream occlusion and 12 psi (83 kPa) for a downstream occlusion.
If these specifications meet the required feed regimen, EnteraLite®Infinity™
can be used to deliver enteral formulas to pediatric patients. ALWAYS VERIFY
RATE, DOSE AND FEED INTERVAL BEFORE PROCEEDING TO FEED.

2. DIRECTIONS FOR USE
Recommendation for First Use:
Since battery may not be fully charged when pump is first received, it is rec-
ommended that battery be charged for 6 hours prior to operating on battery
power (see Page 18 for additional information).
Priming and Loading the
Disposable Set
Step 1:
If you are using the spike set with a vented
bottle or pre-filled bag:
Remove protective cover from spike, and insert
spike into spike adapter of formula container
(Figure 2-1).
If you are using the 500ml or 1200ml dispos-
able set:
Hold bag upright and pour in feeding solution
(Figure 2-2). Close cap securely.
NOTE: Blenderized or aggressively mixed solu-
tions may have foam. If using this type of
solution, allow it to sit for 10 to 15 minutes
before pouring into bag. This will reduce the
chance of an alarm due to air in the tubing.
Step 2:
Remove protective cover from barbed adapter. If
using pole clamp, protective cover may be held
in the groove on back of clamp (Figure 2-3).

7. IMPORTANT PEDIATRIC CONSIDERATIONS
7. Important Pediatric Considerations
EnteraLite®Infinity™can be used on pediatric patients if the specifications of
pump meet delivery requirements of the patient. The specifications of primary
importance are:
The flow rate range of EnteraLite®Infinity™is 0.1 ml/hr to 10 ml/hr in 0.1
ml/hr increments and 10 ml/hr to 600 ml/hr in 1 ml/hr increments.
The EnteraLite®Infinity™pump delivers the dose at the specified rate with-
in +/- 5% volumetric flow rate accuracy under the following conditions:
NOTE: For test methodology refer to ANSI/AAMI ID26-1992 American National
Standard for Infusion Devices. Reported accuracy is based upon a generic vol-
ume accuracy calculation:
Accuracy % = (Volume Delivered - Volume Programmed) x 100
Volume Programmed
utilizing ZEVEX EnteraLite® Infinity™ disposable sets

NOTE: If set is to be used with a carry pack, all
air must be removed from bag and tubing.
Continue to step 3 for instructions on
removing air. If set is to be hung above pump,
i.e. on an IV pole, you may skip to step 4.
Step 3:
Turn bag upside down and gently squeeze. Tilt bag
as needed to keep air at tubing port (Figure 2-4).
Step 4:
Gently pinch teal colored tubing below “ “
symbol. Hold this position until air is removed
from tubing. Gently squeeze bag at same time
to assist fluid flow. If fluid does not flow, pinch
may be too tight (Figure 2-5).
NOTE: Inside the teal colored tubing, below the
“ “ symbol is the in-line occluder. By pinching
