Quick Answer
To use the CeresBFF OG+ Chiller/Warmer with the Pump Lyfe kit, assemble the chiller, attach the pump adapter, pump directly into the inner chamber, then cap and store. Follow the step-by-step directions below for first-time use and on-the-go pumping.
Why the Pump Lyfe Kit Works with the CeresBFF OG+
The Pump Lyfe kit is designed for moms who want to pump directly into their chiller, skipping the step of transferring milk from collection bottles. This saves time and reduces the risk of spills or contamination.
Before you start, make sure your CeresBFF OG+ is clean and dry. The inner chamber is where the milk goes, and the outer chamber holds either ice water for chilling or hot water for warming. Understanding this two-chamber system is key to using it correctly.
First-Time Use: What to Know
If you're new to the CeresBFF OG+, take a few minutes to familiarize yourself with the parts: the outer chamber, inner chamber, lid, and the pump adapter included with the Pump Lyfe kit. The adapter connects your pump flange or breast shield directly to the inner chamber.
A common mistake is overfilling the inner chamber. Leave some headspace to allow for the pump adapter and to prevent spills when you remove the pump. Also, always check that the lid is sealed tightly before you tilt or carry the chiller.
Step-by-Step: Pump, Store, and Warm with the Pump Lyfe Kit
- Prepare the chiller: Wash all parts with warm soapy water, rinse thoroughly, and air dry. Place the inner chamber inside the outer chamber. Add ice water to the outer chamber for chilling (or hot water later for warming). Check that the inner chamber sits snugly and there's no water in the milk chamber.
- Attach the pump adapter: Connect the pump adapter from the Pump Lyfe kit to the top of the inner chamber. Make sure it fits securely to your pump flange or breast shield. A loose connection can cause milk to leak; test the seal with a small amount of water first.
- Pump directly into the inner chamber: Position the chiller on a flat surface and pump as you normally would. The milk flows directly into the inner chamber, keeping it chilled by the surrounding ice water. Do not overfill—leave at least an inch of space at the top to allow for the lid and adapter.
- Remove the pump and seal the chiller: Carefully detach the pump adapter, then screw on the lid tightly. The chiller is now sealed and ready to carry. Double-check the lid is secure before moving to avoid spills.
- Store or warm your milk: For storage, keep the ice water in the outer chamber to maintain a cold temperature for up to 20 hours. To warm milk, empty the ice water and add hot water to the outer chamber, then wait a few minutes before serving. Test the milk temperature on your wrist before feeding—never microwave breast milk.
