INSTALLATION
1.Comfort Zone is a replacement mattress. Place the mattress directly on the bed frame, with the air hose connectors
positioned at the footboard.
2.Hang the pump onto the bed board (footboard side) using the hooks on back of the pump, or place it on a flat surface.
3.Connect air hose connectors from air mattress to the pump unit. Ensure the air hoses are not kinked or tucked
under the mattress.
4.Plug the power cord into the electrical outlet.
5.Turn the power ON.
WARNING!
•Make sure the pump unit is suitable for the local power voltage.
•Do not position the equipment so that it is difficult to disconnect the plug.
MATTRESS & COVER
The mattress is a 10” cell-on-cell type mattress which prevents bottoming out in case of a sudden power outage.
The mattress will temporarily retain air even when the pump is turned off or during a power outage.
Please note this only temporary.
The cover sheet protects the cells against unexpected contamination, and makes cleaning of the mattress easier.
BEFORE USE
Check the correct assembly, paying particular attention to the air hoses connector.
USE WARNINGS
1. Electric shock - Avoid electric shock
It is very dangerous to use electric products improperly or damaged ones.
1) Unplug the pump control unit if you will not use it for a long time.
2) Do not use the pump control unit near water or any other fluid.
3) Avoid having the cable, plug and main control unit being in contact with water or any other fluid.
4) Unplug the pump control unit if or when it is in contact with water or other fluid.

7
Do not open the control unit by yourself. This should only be done by an authorized technician.
2. Safe Place
1) Avoid damaging the plug or cables when moving the patient or bed.
2) Ensure that the cables are safe and tidy and not caught in the bed mechanism or resting on the floor.
3) Keep sharp objects or strong acid and alkali chemical agents away from the mattress.
4) Fuse will blow to protect the device when electric short circuit is caused by the current loading.
3. Cautions - Keep the system away from fire, avoid electric shock or any danger that will cause injury to the user.
1) Only use the system under the supervision of a nurse or caregiver that understands how to operate this device.
2) Do not use any parts that did not come with this unit or supplied by MedaCure or authorized dealer.
3) Ensure that the mattress, cover, cables and power outlet are not in contact with fire, heat or strong acid and alkali chemical
agents.
4) Do not modify the pump and mattress without authorization of the manufacturer and do not insert objects
into the control unit or mattress.
6) Please plug the control unit into the ground power supply.
7) Do not use the product in case of the following:
.1 the plug or the cable is damaged.
.2 the system sounds abnormal or vibrates intensely.
.3 the control unit fell on the floor and caused damaged to the housing
.4 the control unit fell into water or other fluid.
HOW TO USE
NOTE
In case the pressure is constantly low, check for any holes on the interchangeable air cells or on the
connection tubes. If necessary, contact your dealer to exchange the air cells or connection tubes/hoses.
HOW TO USE THE CPR DEFLATOR & INFLATOR
In case of emergency and/or if rapid deflation is necessary, rotate the CPR valve to deflate, as noted below:
1) Connect the CPR to the mattress -
Connect the 3 prongs on the CPR Valve
to the CPR hose on the mattress.
Leave the CPR Valve connected to hose in case of future use.

recommended separation distance
calculated from the equation applicable
to the frequency of the transmitter.
Recommended separation distance:
d = 1,2 √P
d = 1,2 √P80MHz to 800 MHz
d = 2,3 √P800MHz to 2,5 GHz
Where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter
manufacturer and d is the
recommended separation
distance in meters (m).
(a) Field strengths from fixed RF
transmitters, as
determined by an electromagnetic site
survey, should be less than the
compliance level in each frequency
range. (b)
Interference may occur in the vicinity
of equipment marked with the
following symbol:
NOTE1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,
amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the
electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured
field strength in the location in which the CZ42 & CZ48 is used exceeds the applicable RF compliance level above, the CZ42 & CZ48
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as re-orienting or relocating the CZ42 & CZ48
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

The CZ42 & CZ48 is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled.
The customer or the user of theCZ42 & CZ48 can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications

APPENDIX---
BUILT-IN AIR PERIMETER MATTRESS
MODEL # CZ42-BIP & CZ48-BIP
THESE MODELS COME WITH A BUILT-IN AIR PERIMETER
PLEASE CHECK THE BACK OF THE PUMP FOR CORRECT MODEL NUMBER.
The built in air perimeters are located on both the left & right side of the mattress.
This prevents the patient’s arms and legs from getting caught in between the air mattress
and side rail. It also acts as an aid to prevent the patient from falling out of bed.
Please note however that the perimeter is not intended to be a guaranteed protection against falling.
Patient must be under the constant watch of a caregiver to monitor the patient’s movements.
When the patient needs to transfer out of bed, each side can be deflated individually to allow the patient easy access. To
deflate the air perimeter, simply slide open the cover and disconnect the air tubes. Each side can be deflated independently
and inflated again when you re-connect the air tube.
HOW TO INFLATE & DEFLATE THE SIDE AIR PERIMETERS:
Connect the tubes to inflate the perimeter Cover the tubes with the integrated cover
Disconnect to deflate the perimeter when connected to protect the tubes
Tubes are located at the head and foot of the mattress
Press on the blue tab to disconnect the tubes
