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-

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
p
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.

3.2 Utility Connections
Belimed provides an Installation drawing with specific locations for each
supply and its associated requirements. Care should be taken to review the
demands of all supplies listed on your site specific installation drawing.
3.2.1 Electric Supply
The electric supply connection is located on the control panel. The electrical service should
comply with the local building code and be installed accordingly. A service disconnect
should be installed within the supply room to avoid feeding power directly to the Belimed
CS 720.
CS 720 Service Manual Revision 1.1 Page 4

3.2.2 Compressed Air
The pneumatic connection is located on the maintenance unit below the electric control
panel.
The Belimed CS 720 is equipped with a complete manifold assembly containing the
regulator and moisture separator. It is the responsibility of the customer to provide air that is
free from oils, water and impurities, which can harm the control valves.
3.2.3 Steam
There are three Steam connection points, one each at the Supply Tank, Rinse Tank and
the Air Heat Exchanger.
Steam is required to heat the water used in the machine. Wash water is heated in the
supply tank and rinse water is heated within a tube bundle type heat exchanger. Steam is
also required to heat the air for drying.
It is the responsibility of the customer to provide dry steam free from solid particles
and de-watering traps prior to the machine connection point.
The steam is piped into stainless steel coils located in the machine supply tank, air heat
exchanger and the rinse supply tank. Condensate is returned to the building supply through
a steam trap located at the outlet of the machine steam coils. No live steam enters the
machine. The heat transfer from the steam coil to the surrounding water and/or air in the
heat exchangers accomplishes heating of the water and air.
Proper functioning of the steam heating system is essential for proper operation of the
Belimed CS 720.
3.2.4 Drain
Good drainage is essential for proper operation of the machine. The drain connection size
for the machine is 2". The machine circuitry is designed for very rapid draining of the sump
contents through a 2" valve. The building drain should incorporate its own trap or siphon for
odor control and to comply with local code and be of a diameter larger than 2”.
3.2.5 Exhaust
CS 720 Service Manual Revision 1.1 Page 5

In the Belimed CS 720 Washing and Rinsing and Drying are accomplished in the same
chamber.
During the washing and rinsing cycles (1 to 2 minute duration for most wash programs)
vapor will form as the water temperature rises (maximum design temperature = 200 °F or
93 °C). The exhaust fan runs at low speed and draws the vapors out of the chamber and
into the exhaust vent and attached ducting. Depending on duct environmental conditions
(air temperature, air velocity, and relative humidity) some of these vapors will condense in
the exhaust ducting.
To prevent leakage of condensate out of duct joints, proper ducting and sealing techniques
must be complied with. Horizontal runs of duct directly from the machine should be pitched
back to the machine to allow potential condensate to drain back. The machine is furnished
with an exhaust condensate line that will remove condensate under most conditions. Its
design features an 8” stainless steel exhaust pipe outlet, which must be adapted to a 10"
pipe, such that condensate that forms due to the diameter expansion can drain into a 3/8"
nipple, which is connected by tubing to the machine drain. Recommended ducting
materials are stainless steel, polyethylene or galvanized steel pipe. Aluminum is not
recommended for the first few feet prior to connection into larger ducts carrying additional
air, because of possible pitting and sealing problems.
During the drying phase (8 to 12 minutes duration for most wash programs) the exhaust fan
runs at high speed. The incoming air is suctioned through intake channels, and across a
steam powered heating element and into the machine chamber, then across the washed
goods.
3.2.6 Water
The Belimed CS 720 is equipped with two water solenoid valves. It is the responsibility of
the customer to install service valves, back flow and fine particle strainers in each water
connection. Belimed only provides the automatic on/off valve controlled by the Belimed CS
720. Fine strainers are required to prevent the lodging of small solids in the orifice of the
water solenoid valves and thus decrease the water flow rate or render the solenoid valve
non-functional. Small solids lodged in the solenoid valve orifices prevent proper closing of
the solenoid valve and can thus lead to overflow of the machine and flooding. Belimed
makes available for sale water strainers with see-through indicators to show any trapped
solids and to indicate the need for cleaning. Water is used to wash and rinse in all cycles.
Hot water contributes to faster program cycles because it reduces the time needed for the
machine heater to pre-heat the water. It is required that water be softened to bring its
hardness below 90 ppm = 5 grains/gal.
Hardness in wash water (usually in form of calcium and magnesium) affects performance
in two ways:
CS 720 Service Manual Revision 1.1 Page 6

1. It requires considerably more detergent, since much of the detergent is used to neutralize
the water hardness and thus not available for cleaning.
2. Water hardness tends to chemically change with heat such that it becomes non-soluble
in water and thus deposits on the interior walls of the wash chamber and on the heating
coils (i.e. "tea kettle effect"), which impair the heating and drying capabilities of the
machine.
3.3 Emissions
Noise Level: max. 70dB (outside mechanical room)
Heat Radiation in Mechanical Room: 8,200 BTU/hr
Heat Radiation at Entrance: 2,800 BTU/hr
