safety precautions should always be followed, including the following.
READ ALL INSTRUCTIONS BEFORE USE
Caution: Every electrical devise has a potential for danger. To
reduce the risk of burns, electrocution, re, injury, or infection to
persons, take these procautions:
1. Always unplug your Joy multi-user hospital grade breast pump
immediately after use. Unplugging the breast pump is the only
way to assure the power is disconnected.
2. Do not use while bathing or showering.
3. Do not place or drop motor unit (pump) or power supply into
water or other liquid. If either part falls into water, unplug it
from the wall, then remove it from the water. Do not use pump
or power supply again; the pump and power supply cannot be
repaired after being in water.
4. Do not store or use your breast pump where it can fall or be
pulled into a tub, sink, or other water container.
5. To avoid damaging the power cord, do not wrap/wind power
cord around the power adapter.
6. Never operate your pump if it has a damaged power supply cord
or plug.
7. Only use the electric power supply/cord that comes with the Joy
multi-user hospital grade breast pump.

Introduction to Your
Joy Breast Pump
Pump Description
The Joy® 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 Joy 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 Joy 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.
For information on reasons to use a breast pump, please go to

Profession, Edition 8, Missouri, 2016, Mosby
Benets of using Joy 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.

Page 12 Controls and Features
Controls and Features
The pump has two knobs, which control its operation. Rotating the
knobs adjusts the settings. 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. For knob locations, see the
illustration on page 11.
Cycle speed/power 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 cycle speed/power knob
to the right increases the speed and rotating the knob to the left
decreases the speed. The current setting is shown on the display over
the word Cycle. 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. 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 and feel comfortable
with your Joy breast pump. The cycle speed is used to ne-tune the
suction rhythm to best mimic your baby’s suckling.

Page 13 Controls and Features
Vacuum strength knob
The vacuum strength 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 strength knob
to the right increases the strength and rotating the vacuum strength
knob to the left decreases the strength. A vacuum setting of 1 (one)
applies a low suction strength (vacuum). A vacuum setting of 80
(eighty) applies a high suction strength (vacuum). Your Joy 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 Joy breast pump, it’s recommended that you
use a fast suction rhythm (cycle) and low suction strength (vacuum).
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 strength knob to the right, to a suction
strength that feels comfortable to you and similar to your baby’s
suckle.
Note: When vacuum strength is increased, the cycle speed will
decrease slightly.

Page 14 Controls and Features
Secondary Features
Dry Mode: Push Cycle Speed knob to turn pump on. Once pump is
on, hold cycle speed knob down until Dry Mode appears on display.
(This will take about 5 [ve] seconds). Release knob. 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 briey
display “tubing not open try again”; display will return to “Start Dry
Mode.” To cancel drying, press cycle/power knob while pump is
running, then the pump will turn off and reboot.
Favorite Setting: The pump has the ability to store one set of
preferred pumping settings. To activate the favorite setting, press and
release the vacuum/favorite knob while pumping. Once activated,
the display will show “Loading Preset” and the pump will gradually
go to the saved settings. The pump comes with a preset for cycle and
vacuum at a setting of 30 (thirty) for both. The preset settings can
be changed while/when pumping by setting to the desired settings
by adjusting the knobs and then press and hold vacuum/favorite
knob for approximately 5 (ve) seconds or until the display shows
“Saved Preset.” The favorite setting has been set and will return when
vacuum/favorite knob is pressed while pumping. The favorite settings
can be changed as often as you like by following the instructions
above.
Find your comfort settings
Recommended settings for rst-time use:
Cycle speed of 30 (thirty) and a vacuum setting of 1 the pump will
automatically start up with these settings after being unplugged in
or if the pump has been off for more than 5 minutes.
