The Castle 7900 Floor Loading Cart Washer is a fully automatic, floor
loading, hydro-spray cart washer with dual side-by-side wash compartments
that is used to clean and decontaminate case carts, stands, utensils,
containers, tote boxes, and similar bulk items.
Processing cycles are set up using a programmable controller equipped
with a touch screen interface (touch control panel). Four cycle definitions
are possible. The operator needs only to select and start a cycle.
A standard cycle consists of the following sequential phases: wash, rinse,
exhaust, and drying. The length of a cycle’s phase can be adjusted at the
touch control panel.
The washer can be installed in a shallow pit or at floor level. When installed
in a pit, the floor of the washer’s chamber is level with the room floor, which
allows the direct loading and unloading of carts. When the washer is
installed at floor level, the floor is higher than the room floor. Ramps are then
provided as standard equipment to facilitate loading and unloading.
The washer is designed for pass-through operation. Items to be cleaned are
placed in the washer’s compartment through one of the load end doors.
After cleaning, the items are removed from the opposite end of the washer
through the unload end doors.
The washer is generally installed in a facility’s decontamination room with
the unload end doors opening out into a clean-preparation area. The unit is
110" (2794 mm) wide and 108" (2743 mm) high. The washer is currently
available in only one compartment size: 98" (2489 mm).

Installation Requirements
Installation Advisor y
A 7900 washer is assembled at the factory, tested, then disassembled for
shipment. Extensive on-site reassembly is required. The installation
instructions in this manual are intended as the primary reference for
accomplishing this reassembly. Every effort has been made to make this
information as accurate as possible. No two washers are exactly alike,
however.
Each washer is uniquely configured to meet the demands of its operational
site. These demands most often necessitate variances in the location of a
washer's exterior components. These variances, in turn, impact the
configuration of related plumbing and electrical wiring assemblies.
For this reason, some instructions or illustrations carried here may not
reflect the actual location or configuration of selected component
assemblies for a specific site. Where applicable, installers should refer to
specifications contained in the product information documents, such as
Rough-In and Assembly drawings, that have been forwarded to local
Getinge/Castle product support personnel.
Wa sher Options
Floor Mount vs. Pit Mount
Left Side vs. Right Side
Controls
Barrier Flanges and Service
Enclosure
Electrical Service
Printer
There are a number of options that may be included with your washer.
These options affect the procedures that apply to your specific installation.
A floor mounted washer will require the installation of ramps to provide
access to the washer. The two options may have different plumbing
specifications.
The location of controls on your washer will also determine the location of
the service area, as well as the barriers flanges and service enclosure that
may be provided with your washer.
Your installation may have barrier walls at the load or unload end of the
washer, or both, as well as have a service enclosure. These structures will
be designed specifically for your site.
The electrical service at your facility determines the specific high voltage
devices (motors, pumps, etc.), transformer, and control box provided with
your washer.
If your washer has the printer option, the printer will already be mounted on
the control box.
Seismic Anchoring

Washers with the seismic anchoring option have base/sump assemblies
that are mounted differently.

Shipping Configuration
7900 Floor Loading Cart Washer
A disassembled 7900 washer is shipped on 4 to 8 pallets of various lengths.
The maximum size of any one pallet may be as large as 10' x 5'
(approximate). For stability during transit, selected pallets are often pegged
(with nails) to the floor of the truck.
Moving the disassembled washer from the truck to the installation site
requires the use of any available combination of the following:
• fork lift
• pallet jack
• dollies
• Johnson bars
A sufficient supply of commonly used fasteners (#10-32 and 1/4-20, for
example) is bagged for shipment. Speciality hardware and fasteners (door
latches and hinges, for example) are labeled and bagged separately for
shipment.
Many disassembled items, such as plumbing and panel sections, are
marked with handwritten numbers with black grease pen to identify their
location, orientation, or connection points. Take care not to inadvertently
smudge or erase these identifying marks.

NOTE
WARNING
General Instruction
The base/sump assembly is shipped in two halves that you must assemble
on the site. If the load or unload ends of the base are not marked, check the
configuration of the base’s sump against the rough-in drawing to determine
the correct orientation.
Some installation sites may have an existing wall in close proximity to the
non-service side of the washer that could interfere with the assembly of the
washer's side panels. If this situation exists, you will have to seat the base
temporarily out-of-position until the side, top, and non-service side trim
panels are assembled. You can then maneuver the unit to its operating
position, where you can level and anchor it, if required.

Assemble the Washer Panels
Objective
Assemble the door, side, and top panels. Install the required number of
interior side panel seam cover strips and the center mounting bracket.
There are six side panels and three top panels. Each of the end (door)
panels in turn consists of five panels: three vertical panels and two
horizontal panels (one over each door) that connect to the vertical panels.
Door panels and side panels are marked to indicate their location. Top
panels are not marked (check this). The unload end top panel has two
rectangular cutouts for the condenser mountings, a cutout for one of the rear
dryer ducts, and numerous threaded holes on its exterior surface for
mounting the dryer assemblies. The load end top panel one cutout for the
second rear dryer duct and has fewer mounting holes (for a transformer and
plumbing mounting plates). the middle panel has mounting brackets for the
floor tilt actuators. The width of a top panel is the width of the washer (92").
The side panels have 7/16" diameter holes that carry 3/8" thru bolts (five on
each side of the washer) to hold the panels together. The top panels have
holes to carry five thru bolts.
There is no established order to follow for panel assembly. You can start
from the load or the unload end. You can assemble all the vertical panels
first, followed by the top panels; or you can add individual top panels as you
erect the vertical panels. The method illustrated below starts from the load
end and progressively adds top panels as the vertical panels are erected.
NOTE
WARNING
You must clean all mating surfaces with thinner, then treat with silicone
primer, and then apply a generous amount of silicone sealant.
Installation
Refer to Figure 2–4. Assembling the Washer Panels for help to identifying
