1.3 General Information

1.3.1 General Precaution

Please read this manual carefully before setting up the machine.

Only personnel who read the operating instructions and safety

precautions should operate, maintain or repair the machine.

ATTENTION

No liability will be accepted in respect of damage occurring to the machine by non-

compliance with these instructions. These instructions only refer to this Belimed CS 720

machine. Belimed reserves the right to make technical changes, which improve the

operation, maintenance or safety of the equipment.

1.3.2 Description of the Belimed CS720

The Belimed CS720 is a single chamber machine. The washing and drying chamber is

constructed primarily of polished stainless steel. All interior panels and components are

stainless steel and are well insulated with 1.5” of fiberglass insulation. Each panel is

covered with a steel panel on the exterior to protect the insulating material and reduce

unwanted noise. The wall sections transfer heat at the rate of 8,200 BTUs at the chamber

sides. All associated hardware to attach the panels and other structures are stainless steel.

All welds on the chamber and other components are dressed and polished to a matched

finish. Each cartwasher has a tilt mechanism installed to allow for liquid draining during the

wash, rinse and dry cycles. All components that can be harmed by the chamber

environment are mounted to the exterior of the chamber. Mounted in the top of the chamber

is a glass window for illumination of the chamber. A light is mounted on the exterior away

from harmful vapors and shines through the window. The Supply cabinet mounted to the

exterior chamber wall, in the supply room, houses all the electrical components and

process control unit needed to operate the Belimed CS 720.

The Belimed CS 720 is installed between the clean and the unclean sides in a 5” pit to

allow for loading level with the finished floor.

The Belimed CS 720 is equipped with two pairs of bi-folding doors. One each at the load

and unload ends of the chamber. All doors are constructed of polished stainless steel inside

and out. They are fitted with rigid foam insulation between the panels and welded together

to form a sealed door. The doors effectively control heat transfer to 2,800 BTUs at the

entrance and exit. Each bi-folding section contains a 7.5” round window of tempered glass

for clear visibility through the washer. Attached stainless steel shafts and a guide track

mounted to the chamber, guides the door’s leading edge. The doors are opened and closed

via a pneumatic piston. The piston rotates a solid 1” shaft at the exterior of the chamber,

which is mounted vertically through the entire door and protrudes through to the exterior of

the chamber. The door’s opening and closing are controlled by the process control. Care

CS 720 Service Manual Revision 1.1 Page 6

has been taken to ensure that only one door can be opened at any one time In accordance

with Hospital guidelines as published in “Guidelines for Design and Construction of

Hospitals”. This publication states that the Decontam room shall be physically separated

from all other areas of the department. If the doors remain open, cross contamination is

allowed and the airflow balance is disrupted. If any of the folding doors are not tightly

closed, the process control will prevent the start of a program.

1.3.3 Design Features

Chamber Design: The Stainless Steel pan is self-supported without seams to protect

against leaks. The roof is designed as a ridged structure to support the additional

components. The stainless steel ceiling is pitched to avoid accumulation of water droplets.

External surfaces, roof and sides, are insulated with fiberglass and covered with galvanized

steel sheeting.

Supply Tank: This separate unit consists of a tank, insulated on all sides and a circulation

pump made of stainless steel. The wash water is heated inside the supply tank by a steam

coil and control valve. A built in overflow skims the surface water as it is returned during

the wash and rinse cycles.

Rinse Heat Exchanger: The rinse water is heated inside the tubular heat exchanger by a

steam coil and control valve. Hot water passes through the heat exchanger during the rinse

cycle to super heat the loaded carts and rinse away residues from cleaning.

Liquid Return Pump: A self-priming vertical pump made of stainless steel allows a rapid and

complete return of the washing liquid and rinse liquids out of the chamber and back to the

supply tank for re-circulation

Spray Ring: The spray ring consists of 2 rings provided with spray nozzles. The bottom ring

for washing and the upper ring for rinsing. The spray ring moves in a vertical direction. The

lift of the spray ring and the number of repetitions (one complete down and up of the ring)

for both washing and rinsing is adjustable. The Lift of the spray ring is determined by the

height of the carts to be washed. For example:

Medium Cart

position 2

Low Cart

osition 1

Tall Cart

position 3

CS 720 Service Manual Revision 1.1 Page 7

The motor for the spray ring is located on the chamber ceiling. If the spraying frame gets

blocked in its upward or downward movement a safety switch stops the movement of the

spray ring to prevent damage to carts.

Chemical Dosing Unit: The Belimed CS 720 is equipped with two chemical additive pumps

that are located in the supply room and draw chemical through a poly-braid hose to the

pump and then eject the chemical under pressure into the supply tank and rinse water. The

chemical pumps are equipped with low-level sensors for the chemical additive. When the

chemical additive is low the status will be displayed at the master control. The pumps can

be adjusted directly at the pump and controlled further by timers in the process control

software.

Pneumatic Unit: All the valves and regulators required for the pneumatic operation of the

machine are mounted on a manifold that is easily accessible. The valves can be controlled

manually at the valve and electronically through the service mode.

Exhaust Equipment: The air exchange within the chamber is carried out by a radial exhaust

fan on the chamber ceiling. The fan has two operating speeds. The fan draws out excess

vapors during the wash and rinse steps and maintains negative pressure within the

chamber at low speed. In the dry step air is drawn in across a air heat exchanger to dry the

carts. The removal of all vapors is accomplished before program completion.

Tilt Mechanism: By means of pneumatically driven cylinders mounted on the chamber roof

the traveling rail pallet can be brought into an inclined position during both wash and dry

programs. The inclined position prevents formation of water puddles on flat cart surfaces

and increases the drying effect.

installation of unauthorized parts could cause personal injury or result in

costly damage.

•Observe the dangerous voltage labels. Switch off power to machine before opening

electrical cabinets.

•BURN HAZARD: Allow the machine and its accessories to cool to room temperature before

performing any cleaning or maintenance procedures.

•This machine is NOT DESIGNED TO PROCESS APARATUS CONTAINING FLAMMABLE

LIQUIDS.

•BURN HAZARD: All Goods coming out of the dryer will be HOT TO THE TOUCH.Wear

gloves if a cart is to be handled right away.

•BURN HAZARD: Exercise extreme caution when crawling on top of the machine. Steam

piping might be exposed and burn you. Also the stainless steel ducting might be hot and

can burn you.

•BURN HAZARD: Holding tanks piping and piping alongside machine are hot and can burn

you. Exercise care when walking around tanks.
