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.

RQD032ENr02 Rev. Date: 2021-12-24

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 whois familiar with transfer techniques and options. Individuals who have notlearned safe transfer

skills must seeks assistance during transfers and may require the use of a mechanical lift.

RQD032ENr02 Rev. Date: 2021-12-24

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 castersfrom 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.

IMPORTANT !

DO NOT LIFT A RAZ SHOWER COMMODE CHAIR AND OCCUPANT BY THE ARMRESTS OR

FOOTRESTS.

IMPORTANT !

4.0 USE AND OPERATION

4.1 Casters

Each caster is equipped with a dual-lock feature, which stops

the caster from swiveling and rolling simultaneously. To activate

the dual-lock, step on the end of the caster brake until it latches

in the “on” position. To deactivate the dual-lock, step on the

raised end of the dual-lock until it latches in the “off” position.

4.2 Wheel Locks

The wheel locks on a Züm-SP can be engaged by pushing the

handles forward. This stops the rear wheels from rotating. For

maximum stability, both wheel locks must be engaged. To

disengage the wheel locks, pull the handles backward.

4.3 Commode Pan

The Raz commode pan is designed with an elongated shape

that fits directly under the seat to minimize back splash. A

unique splash-reduction ridge is located at the center of the pan.

The high gloss surface facilitates cleaning and rinsing, while the

pouring spout and handle facilitate emptying. Removal of the

commode pan is achieved by sliding the pan rearward.

When re-inserting the pan, ensure that the pan is guided into the green

plastic brackets and pushed forward until it hits the stops.

IMPORTANT !

DO NOT USE ABRASIVE SCRUBBING POWDERS OR SCOURING PADS ON THE Züm-AP/SP.

DO NOT SUBMERGE THE Züm-AP/SP IN WATER.

RINSE THOROUGHLY AFTER CLEANING TO ENSURE THAT ANY SOAP OR DETERGENT

RESIDUE IS REMOVED.

DO NOT USE CLEANING PRODUCTS WITHOUT CONSULTING THE PRODUCT’S INSTRUCTIONS

AND TAKING APPROPRIATE PRECAUTIONS FOR HUMAN EXPOSURE TO CHEMICALS.

DO NOT USE CHLORINATED PRODUCTS ON THE Züm-AP/SP.

RQD032ENr02 Rev. Date: 2021-12-24

5.0 CLEANING AND MAINTENANCE

5.1Cleaning After Each Use

5.1.1 Commode Pan

1. Remove the commode pan and empty contents.

2. Wash the pan with a multi-purpose disinfectant cleaning solution. Use a soft brush if needed.

3. Rinse well before storage or re-use.

A soapy hot water wash followed by a disinfectant spray can be substituted for a multi-purpose disinfectant cleaning

solution.

5.1.2 Seat

1. Spray with a multi-purpose disinfectant cleaner and scrub with a soft brush as required.

2. Rinse with a water spray before storage or re-use. DO NOT IMMERSE the seat in water or cleaning

solutions.

3. For a more thorough cleaning, remove the seat from the shower chair to allow better access to the

underside of the seat and around the opening of the seat.

5.2Cleaning As Needed

5.2.1 Frame, Armrests, Adjustable Footrests, and Other Components

1. Spray the frame and components with a multi-purpose disinfectant cleaner, scrub with a soft

brush and rinse with water.

It is recommended to the user that a qualified Raz dealer check over all fasteners and subassemblies on

a continuing basis or if there is cause for concern to the shower chair’s performance.

To reduce the risk of mildew buildup, the entire shower chair should be wiped down with a soft dry cloth

after the final rinse and before storage or use.

The Züm-AP/SP must be stored in a dry and clean environment. Avoid exposure to chlorine (e.g.

pools and pool areas), which will deteriorate and discolor the chair over time.
