SPECIAL SAFETY INSTRUCTIONS
SPECIAL SAFETY INSTRUCTIONS APPEAR BELOW. READ THEM
CAREFULLY BEFORE OPERATING THE UNIT.
“Warning”notes alert the user to the possibility of personal
injury.
Safety Precautions
WARNING —FALL HAZARD: Areas located immediately around the
washer may become a fall hazard due to water dripping. For a safe
environment, keep the floor clean and dry.
WARNING —BURN HAZARD: This washer operates at extremely high
temperatures.
•Hot water and steam can cause injury such as burns. Use caution in and
around the washer chamber and external piping.
•Steam may escape when the door is opened. Stand back and to the side
when opening the door.
•Allow the load to cool before removing it from the chamber.
•Allow the washer to cool down prior to any maintenance.
WARNING —SHOCK HAZARD: Disconnect all utilities and follow standard
lockout/tagout procedures for your workplace before performing
maintenance on the washer.
WARNING —PERSONNEL HAZARD: Safe and efficient operation of this
equipment requires scheduled preventive maintenance. Routine
adjustments and replacement of parts by other than qualified maintenance
personnel may cause personal injury or equipment malfunction.
Running a Cycle
BURN HAZARD: Steam may escape when the door is opened. Stand back
and to the side when opening the door.

Section 1 General Description
INTRODUCTION
Figure 1–1. ,MTP1800 Series Washers
The MTP1800 series units are an automatic, heavy-duty, single chamber,
cabinet- type, hydrospray washers. The units are designed to efficiently and
thoroughly clean and sanitize cages, bottles, debris pans and utensils used
in research animal care facilities.
Units are available in vertical or drop down door configurations. Units are
floor mounted and may be recessed through one or two walls or installed
free standing. Left side service access and control terminal location is
standard with right side service access and control terminal location
optional.

General Description
1–2
Models and dimensions are listed in Table 1-1.
The above dimensions are the maximum chamber opening. The load size
must be smaller to allow for loading clearances.
Routine operation consists of placing the load to be cleaned in the chamber,
close the chamber door, select the desired cycle, and press the cycle start
button. The washer automatically proceeds through the treatment process
and alerts the user when the process is complete. The user then opens the
chamber door and removes the cleaned load.
At the end of the processing period, the user places the unit in the
STANDBY mode. All processing functions will immediately stop and the
sump will automatically drain.

Spray Manifold Delivers the various wash and rinse spray treatments to the load during a
processing cycle. Vertical and horizontal sections - fitted with spray nozzles
- make up the complete assembly.
Guide Rail (not shown) Functions as a restraint to keep items, such as utensil carts, from being
improperly positioned. Four rails are provided on the inside of the chamber
door.
Sump Holds the supply of solution (wash and rinse) that is pumped to the Spray
Manifold during a processing cycle. During processing, it collects all
drainage for recirculation. A steam heating coil installed in the sump
maintains the temperature of the wash solution, and other treatment
solutions - if specified.
Header Drive Motor Moves the Spray Manifold back and forth inside the chamber during the
processing cycles.

MOST COMMON OPTIONS
Strip Chart Printer A strip chart printer with paper take-up, records all cycle program and in-
process performance data. Each cycle program, including time and
temperature set points, may be printed on demand. In-process cycle data is
automatically printed at the beginning and end of each cycle phase, as well
as at the beginning and end of each cycle phase, to provide a chronological
time/temperature profile of actual cycle performance.
Vertical Powered Door The door is powered open and closed to permit ease in loading and
unloading the chamber. The system includes door activation switches and
status lights at the door location, which are wired to the automatic control
system.
Double Door
Pass-Through
The unit is provided with an additional door for pass through operation and
is complete with an unload end user control panel.
Electric Heat Stainless steel, electric immersion heaters are provided in the sump in place
of the steam coil heater to maintain the recirculated treatment solution
temperature. The unit requires a separate electrical connection.
Automatic Agent Injection
System
TIME BASED
A non-monitored, time based, volumetric type injection system is provided
to automatically meter user supplied liquid cleaning agent into the sump.
(Two systems are required if an alkaline and acid treatment solution are to
be used).
MONITORED
A monitored proportional type injection system is provided to automatically
inject user supplied liquid cleaning agent into the sump. The treatment
solution concentration is sensed with a probe, and a proportional amount of
agent is injected to attain and maintain the selected agent concentration.
(Two systems are required if an alkaline and acid treatment solution are to
be used.)
Internal Chamber
Illumination
An exterior vapor proof port and light is provided to illuminate the chamber
interior.

61301604086 1–9
Automatic Self-Cleaning
Debris Filter
The output of the wash pump is provided with a self-cleaning debris filter.
The filter is attached to the treatment pump and is back-flushed by a ball
valve operated by the control system. The filter screen may be accessed
without the use of tools.
An additional perforated stainless steel debris basket is provided above the
recirculated tank to prevent large debris from entering the piping and pump
system. The screen can be easily removed for cleaning.
Drain Discharge Cool-
down System
NON-MONITORED
Cold tap water is automatically injected into the drain discharge to lower the
discharge temperature to below 140°F before entering into the building’s
drain system.
MONITORED
