Section X – Pump Flow Accuracy Test
Certifying the Accuracy of Pump Flow Rate
Use the following procedure to check the ow rate accuracy:
• Perform test at room temperature 22° C ± 2° C (72° F ± 3° F) with a new pump set.
• Fill a new Feed-Only pump set bag with water to the 500 mL mark.
• Load the pump set.
• Suspend the Pump Set so that the bottom of the formula container is 18” (46 cm) to the top of the pump.
• Make sure pump is plugged into A/C power (do not run test with battery power).
• Program a Continuous Mode feed rate (see below for suggested example rates).
• Run the pump for 15 minutes to achieve steady state operation.
• Then begin collecting the water in a calibrated measuring container for exactly 30 minutes.
NOTE: The amount of water collected in 30 minutes will be half of the value programmed for the hourly ow rate, within ± 10%, or 0.5 mL, whichever is larger.
NOTE: Accuracy testing is critically dependant on the proper use of calibrated equipment. Trained technicians familiar with volumetric measurements of uids should perform
the accuracy testing. It is recommended that a 100 mL calibrated glass graduated cylinder (TC “to collect”) be used for these measurements. An error of just a couple of
mL’s on a volume of 125mL can be the dierence between pass/fail for this accuracy test.
Rate Set Amount Expected in 30 Minutes
75 mL/hr 33.7 mL to 41.3 mL
150 mL/hr 67.5 mL to 82.5 mL
If the amount collected is outside the range, load a new pump set and re-run the test procedure to conrm results.

General Pump Maintenance
Battery Replacement
See Figure 5 and complete the following steps to replace the battery pack (9):
1. Power down the unit.
2. Loosen the battery door screw (10), on back of pump.
3. Open battery door (10) and disconnect wire harness. A small straight-bladed screw driver may be needed to disconnect the connector tab.
4. Slide battery pack (9) out of compartment.
5. Slide a new battery pack into compartment with wire harness extending out.
6. Align connector with red wire at upper right.
7. Push connector in until properly latched.
8. Tuck wires into slot between connector and battery to insure wires are not pinched. Re-tighten battery door screw.
Note: Replacement Battery Packs are available from Tyco Healthcare Group LP (See Section XII)
WARNING: USE OF A BATTERY PACK NOT SUPPLIED BY TYCO HEALTHCARE GROUP LP CAN BE DANGEROUS AND VOIDS ALL WARRANTIES AND PERFORMANCE SPECIFICATIONS.
The battery will charge continuously whenever the pump is plugged into a wall outlet. Eight hours of charging is required to fully recharge the battery pack.
Maintenance Requiring Disassembly of Internal Components
Full Disassembly Instructions (See Figures 5, 6, and 7)
1. Remove battery door/battery door screw (10) and battery pack (9).
1.1. Loosen the battery door screw (10) on back of pump using a small Flathead screwdriver.
1.2. Unsnap battery door (10) from back housing by applying pressure to the underside of the battery door with door partially closed.
1.3. Disconnect wire harness. A small straight-bladed screwdriver may be needed to disconnect the connector tab.
1.4. Slide battery pack (9) out of compartment.
2. Remove main door (12).
2.1. Use directed pressure to lift the main door (12) top hinge hole o the top post of the back housing (7).
2.2. Slide the main door bottom hinge hole o the bottom post of the back housing.
3. Remove the rotor assembly (19) from the gearbox shaft (13) by loosening the set screw using a 5/64” Allen Wrench.
4. Peel the white bump on (22) o the back housing (7).
5. Remove the two Vinyl foot covers (20) from the base of the back housing (7) by peeling free from adhesive.
Note: Vinyl foot covers (20) are likely to become damaged during disassembly. See Section XII - Assembly Diagrams and Reorder Numbers to order replacement Vinyl foot
covers.
6. Separate the front housing (2) from the back housing (7).
