Page 6 Introduction to Your PJ’s Comfort Breast Pump
Introduction to Your
PJ’s Comfort Breast Pump
Pump Description
The PJ’s Comfort® hospital grade multi-user breast pump is intended
to express and collect milk from a lactating woman’s breast. This
action helps to alleviate engorgement of the breast, maintain the
woman’s ability to lactate, and provide mother’s milk for future
feedings when mother and baby are separated.
Purpose of PJ’s Comfort multi-user
hospital grade breast pump
The purpose of the breast pump is to express and collect breast
milk. Milk can be collected from both breasts at the same time
(double pumping) or from just one breast (single pumping). Specic
instructions appear on page 22 and in the “Expressing Milk”
section beginning on page 24.
Multiple users: The pump can be used by several women (at different
times). For safety, it’s important that each woman have her own
accessory kit with lter. See page 29 for instructions.
Reasons to use a breast pump
The intended use of the PJ’s Comfort multi-user hospital grade breast
pump is to express milk from the breast of a lactating woman.
Breast milk is the best possible nutrition you can give your baby.
Breast-feeding allows you to give your baby the best possible start
in life. While putting your baby to the breast is one way the baby
will receive breast milk, there are several reasons for pumping and
feeding your baby expressed breast milk.

Page 7 Introduction to Your PJ’s Comfort Breast Pump
For information on reasons to use a breast pump, please go to
bfmed.org or nd this book at your library or bookstore:
Lawrence, RA, Lawrence, RM: Breastfeeding: A Guide for the Medical
Profession, Edition 8, Missouri, 2016, Mosby
Benets of using PJ’s Comfort electric breast pump
• Establish and maintain milk production by emptying the breast if
breast-feeding is temporarily interrupted
• Increase milk production
• Continue to provide infant with breast milk when mother and
infant are separated

Accessory Kit Sanitizing
Before using the accessory kit for the rst time
Caution! Unless there is a label stating sterile on the kit, the
accessory kit is not supplied sterile. It’s not necessary that the parts
be sterile, but some must be sanitized before the rst time you use
the pump. After the rst time you use the pump, the accessories will
only need a simple cleaning procedure, see page 31-5.
DO NOT BOIL THESE PARTS
The lter, tubing, connector, clamp, and “Y” connector do not need
to be sanitized as air is all that ows through the parts. The lter is
designed to last the duration of your current breast-feeding goals.
See “Caution” on page 25 to prevent clogging.

Controls and Features
The pump has two control knobs. Rotating the knobs adjusts the
settings. When a knob is adjusted, the time display automatically
changes to show the setting value, then switches back to time
shortly after the adjustment has stopped. The knobs increase/
decrease a displayed value. If you continue to rotate the knobs the
values will continue to change until the value reaches its limit. When
the setting reaches its limit, the setting will blink if you continue to
turn the knob, to let you know you have reached the limit. For knob
locations, see the illustration on page 11.
Cycle speed/power adjustment knob
Pressing the cycle speed/ Power knob starts and stops the pump
motor. Rotating the cycle speed/power knob controls the suction
rhythm (cycle). It does this by changing the speed of the pump motor
to pump faster or slower. Rotating the knob to the right increases
the speed and rotating the knob to the left decreases the speed. An
example of the suction rhythm (cycle) is when the soft silicone breast
cup collapses around the areola (dark area behind your nipple) and
releases. This can be related to how many times your baby sucks per
minute.
The slowest suction rhythm (cycle) is with a cycle speed of 1 (one).
This provides the fewest compressions per minute. A cycle speed of
30 (thirty) provides the greatest number of compressions per minute
and is the most comfortable setting. The suction rhythm (cycle) also
determines how long the suction strength (vacuum) is applied to
your breast. For example, a slow suction rhythm (cycle) would apply
suction strength (vacuum) for a slightly longer period of time. On
the other hand, a faster suction rhythm (cycle) would apply suction
strength (vacuum) for a shorter period of time (more comfortable).
Adjust the cycle speed only after you have used the pump 2-3 times

Page 13 Controls and Features
and feel comfortable with your PJ’s Comfort breast pump. The cycle
speed is used to ne-tune the suction rhythm to best mimic your
baby’s suckling.
Vacuum adjustment knob
The vacuum adjustment knob controls the suction strength
(vacuum) for balancing effectiveness and comfort and will also slow
down cycle speed as vacuum is increased. Rotating the vacuum
adjustment knob to the right increases the strength and rotating the
knob to the left decreases the strength. A vacuum setting of 1 (one)
applies a low suction strength (vacuum). A vacuum setting of 30
(thirty) applies a high suction strength (vacuum). Your PJ’s Comfort
breast pump always maintains a slight vacuum.
Since each mother/baby couple’s breast-feeding experience is
different, the adjustment of these knobs will be an individual choice.
The goal is to adjust the suction rhythm (cycle) to what best mimics
your baby’s sucking pattern and to adjust the suction strength
(vacuum) to a comfortable setting. Note that the vacuum setting will
also affect the suction rhythm (cycle). Increasing the vacuum level
will decrease the number of cycles per minute (slow cycles).
Adjusting the cycle speed will not change the vacuum level. Cycle
speed is independent of vacuum strength.
When you begin to use PJ’s Comfort breast pump, it’s recommended
that you use a fast suction rhythm (cycle) and low suction strength
(vacuum). The pump is programmed to start at this setting when
rst used or if pump is left off for more than 5 (ve) minutes. This will
create a utter like sensation and allow for a comfortable setting so
you can get used to the pump.
After 1-2 minutes of pumping, increase the suction strength (vacuum)
by rotating the vacuum adjustment knob to the right until it feels
comfortable and similar to your baby’s suckle.

Page 14 Controls and Features
Note: When vacuum strength is increased, the cycle speed will
decrease slightly.
Secondary Features
Dry Mode: To enter Dry Mode, turn the pump on and hold down the
cycle speed/power knob (1) until the number 5 light turns on (this will
take about 5 [ve] seconds). Release knob and the light will begin to
blink rapidly. Attach lter and tubing without breast cup assembly
and press power to start drying mode. Pump will turn on for 5 (ve)
minutes and display remaining time. If vacuum level gets too high
the pump will stop and the number 5 light will begin to blink rapidly
again. To cancel drying, press cycle speed/power knob while pump is
running and pump will turn off and reboot.
Find your comfort settings
Recommended settings for rst-time use
Cycle speed of 30 (thirty) and a vacuum setting of 1 (one).
The pump will automatically start up with these settings after being
unplugged or if the pump has been off for more than 5 minutes.
Adjusting vacuum strength and cycle speed
Vacuum: Pump for the rst minute or two before adjusting
the vacuum. It’s recommended to increase the vacuum in
small increments up to the level that feels comfortable to you.
Recommended pumping time is about 15-20 minutes or 2 minutes
after milk stops to ow.
Cycle: The cycle speed knob is used to ne-tune the suction rhythm
to best mimic your baby’s suckling. It’s recommended that you
wait to adjust the cycle speed until you’ve pumped several sessions
