SAFETY PRECAUTIONS
Failure to comply may cause injury or damage!
It is important that the ZÜM-AP/SP Mobile Shower Commode Chair be properly
assembled and that all adjustments be made carefully. Please ensure that the
user(s), dealer(s) and attendant(s) have read this manual and thoroughly
understood the safe operation of the ZÜM-AP/SP Shower Chair. For
clarification of any section of the manual, contact Wealden Rehab.
PRODUCT MAXIMUM USER WEIGHT
Züm-AP/SP 160 kg (352 lbs)
SAFETY WARNINGS TO CONSIDER FOR RETAIL PURPOSES
THIS DEVICE IS SUITABLE FOR TYPE A; HIGH USAGE (e.g. INSTITUTIONS) AND SHOULD
NEVER BE USED FOR ANY PURPOSE OTHER THAN ORIGINALLY INTENDED
Forward Stability
The casters on all models are equipped with dual locks. The step-on lever
activates both the roll lock and the swivel lock. It is essential that all
casters on the shower commode chair be in an outward position
before engaging the locks, for optimal forward, rearward and lateral
stability.
USERS MUST NOT lean forward while sitting in the ZÜM-AP/SP as this
may cause the chair to tip forward.
USERS MUST NOT wheel up or down a ramp without an attendant who
can hold onto the ZÜM-AP/SP during the ascent or descent.
CASTER LOCKS AND WHEEL LOCKS ARE NOT BRAKES! Never
use the caster locks or wheel locks to slow down the ZÜM-AP/SP
when descending inclines as this could cause the chair to tip in the
direction of travel.
Lateral Stability
USERS MUST NOT lean over the edge of the ZÜM-AP/SP as this could
cause the chair to tip.
USERS MUST NOT attempt to pick up objects from the floor by leaning
over and reaching – a reacher or grabber tool should be used, or seek
assistance from an attendant.

3
USERS MUST NOT position the ZÜM-AP/SP on a side slope as this could
cause it to tip.
Rearward Stability
USERS MUST NOT wheel up an incline on a SP Model without ensuring
that the optional rear anti-tippers are in place. The optional anti-tippers
must be ordered with the ZÜM-SP and properly installed before wheeling
on uneven surfaces.
Anti-Tippers - SP Model
Anti-tippers are an option for the ZÜM-SP Shower Chairs. These are
recommended whenever the chairs are to be used on uneven surfaces
such as ramps or sloped floors, when used by lower-limb amputees, when
the rear wheels are moved forward from the factory-set position or for any
situations when rearward stability is compromised. If unsure, stability
should be checked with the assistance of an attendant.
Ramps and Other Inclines
Ramps or other surfaces that are not level (such as slopes into wheel-in
showers) must be tested with an attendant to ensure the stability of the
chair is not compromised. A qualified healthcare professional should be
consulted to assist with this process.
DO NOT push or pull the ZÜM-AP/SP up or down an incline or ramp
that exceeds a 1:12 grade (5° slope).
DO NOT allow any user to be propelled (pushed or pulled) in any other
manner than by an attendant in a ZÜM-AP or by the user in a ZÜM-SP.
IMPORTANT !
THE REARWARD STABILITY OF THE ZÜM-SP IS AFFECTED BY THE MOUNTING LOCATION OF
THE REAR WHEELS AND THE PHYSICAL AND CLINICAL CHARACTERISTICS OF THE USER. THE
NEED FOR ANTI-TIPPERS SHOULD HAVE BEEN DETERMINED AT THE TIME OF THE
PRESCRIPTION OF THE ZÜM-SP WITH CONSIDERATION FOR THE USER’S PHYSICAL
ATTRIBUTES AND ENVIRONMENT. ANTI-TIPPERS MAY BE ORDERED AS A RETROFIT AT ANY
TIME IF IT IS DETERMINED THAT THEY ARE REQUIRED.
Immersion
The ZÜM-AP/SP is not designed to be used as a pool chair. Do not immerse the shower chair in whole or in
part, in water or any other liquid. Damage to the shower chair components may result.
Transfers
The most dangerous part of using any shower chair is the transfer. Since every chair has different stability
characteristics, it is essential to carefully review and test the transfer technique to ensure that the procedure is
safe. Test transfers should be performed with an attendant who can prevent the chair from tipping or moving
during the transfer. If you feel that the transfers cannot be repeatedly performed safely, contact a healthcare
professional who is familiar with transfer techniques and options. Individuals who have not learned safe transfer
skills must seeks assistance during transfers and may require the use of a mechanical lift.

4
Transferring onto the ZÜM-AP/SP Shower Chair
For the ZÜM-AP, always lock all four casters in their outward position
(front casters positioned in the forward position/rear casters positioned
to the rear) for maximum chair stability. For the ZÜM-SP, always lock the
rear wheels and front casters for maximum stability.
Transfers should never be attempted with the shower chair
positioned on slippery surfaces. It is recommended that transfers be
performed on clean, dry, non-slippery surfaces. Hard surface flooring
such as tile, wood or concrete may not provide sufficient grip to keep
locked casters from sliding. A fully-carpeted surface is optimal. Be aware
that area rugs and shower mats can slide on floors and thereby present
a hazardous surface.
DO NOT stand on any part of the frame of the ZÜM-AP/SP.
NEVER use the footplates to assist in transfers. This could cause the
chair to tip. The footrests should be swung to the side or removed
entirely during transfers to provide unobstructed access to the ZÜM-
AP/SP.
The ZÜM-AP/SP is NOT intended for use as a transportation device or
a long-term seating system.
IMPORTANT !
USERS SHOULD NEVER BE LEFT UNATTENDED IN A RAZ SHOWER CHAIR.

2. SET-UP
2.1 Base Frame Set-Up
Follow these steps to unfold the ZÜM:
1. Rotate front seat support tubes to their outward position.
2. Using your palms, unfold frame by gently pushing down and outward on the upper portions of the cross-
braces until they hook onto the upper side frame tubes.
Be careful not to pinch your hands in the process.
3. Rotate front support tubes inward until the roller pin rides over the bump on the upper portion of each
cross-brace and prevents them from lifting.
An audible click should be felt and heard when the roller pin is securely in place.
Follow these steps to fold the ZÜM:
1. Rotate front seat support tubes to their outward position.
2. Lift both upper cross-braces at the same time.
3. Continue lifting until upper portions of cross-braces touch.
4. Rotate front seat support tubes until they are parallel to the side frames.

2.2 Caster Installation
Tool required: 5mm hex key
1. Insert the caster stem into the base frame.
2. Align the threaded hole in the caster stem with the hole in
the base frame.
3. Insert the M8 button head screw into the caster housing.
Ensure each screw has a thread-lock patch of medium strength
thread-locker solution on its threads before using.
4. Thread the M8 screw through the base frame and into the
caster stem.
5. Ensure the screw is tightened and caster is secure.
6. Repeat steps 1 to 5 until all casters are secured.
Note: Two front casters are required for ZÜM-SP and four casters are
required for ZÜM-AP.
2.3 Backrest Installation
1. Insert the back posts into the back frame receivers.
2. Align the threaded hole in the back post with the hole on the
back frame receiver.
3. Thread the tri-lobe into the receiver and back post.
4. Ensure the tri-lobe is tightened and back post secured.
5. Repeat steps 2-4 for the other side.
2.4 Seat Installation
1. Ensure that the front brackets are in the open position.
2. Position the seat at a ~25° angle with the rear of the seat
sloping downward.
3. Align the latch plates (located on both ends of the rear seat
tube) with the receiver slots in the base frame. The slots are
located immediately in front of the back posts.
4. Lower the front of the seat so the front seat brackets nestle
around the front support tubes.
5. Close the front seat brackets.
6. Pull upwards on the rear of the seat to ensure it is locked in
place.
