I. Important Safety Information
SAFETY INSTRUCTIONS
The equipment described in this Manual is designed and manufactured to operate within defined
design limits. Any misuse may result in electric shock or fire. To prevent the equipment from being
damaged, the following rules should be observed for installation, use and maintenance. Read the
following safety instructions before operating the instrument.
POWER
POWER CORD: Use only the power cord specified for this equipment and certified for the country of use. If the
power (mains) plug is replaced, follow the wiring connections specified for the country of use. When installing
or removing the power plug, hold the plug, not the cord.
The power cord provided is equipped with a 3-prong grounded plug (a plug with a third grounding pin).
This is both a safety feature to avoid electrical shock and a requirement for correct equipment operation. If the
outlet to be used does not accommodate the 3-prong plug, either change the outlet or use a grounding
adapter.
FUSES: Replace fuses only with those having the required current rating, voltage and specified type such as
normal blow, time delay, etc. DO NOT use makeshift fuses or short the fuse holder. This could cause a shock
or fire hazard or severely damage the instrument.
OPERATION CAUTION
DO NOT OPERATE WITH COVERS OR PANELS REMOVED. Voltages inside the equipment consist of line
(mains) that can be anywhere from 100-240VAC.
DO NOT OPERATE WITH SUSPECTED EQUIPMENT FAILURES. If any odor or smoke becomes apparent
turn off the equipment and unplug it immediately. Failure to do so may result in electrical shock, fire or
permanent damage to the equipment. Contact the factory for further instructions.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE: Operating the equipment in the presence of
flammable gases or fumes constitutes a definite safety hazard. For equipment designed to operate in such
environments the proper safety devices must be used such as dry air or inert gas purge, intrinsic safe barriers
and/or explosion-proof enclosures.
DO NOT IMPEDE THE CHAMBER FROM VENTING EXCESS PRESSURE. The humidification and
dehumidification systems are open loop systems that pump external air into the chamber. If the chamber is not
allowed to vent, pressure could build up and cause serious damage to the chamber.
IF YOUR UNIT INCLUDES OPTIONAL LIQUID NITROGEN COOLING CAPABILITES, REVIEW ALL
SAFETY INFORMATION IN THE LIQUID NITROGEN SAFETY ADDENDUM.
DO NOT USE IN ANY MANNER NOT SPECIFIED OR APPROVED BY THE MANUFACTURER:
Unapproved use may result in damage to the equipment or present an electrical shock or fire
hazard.

Controller
Operating Systems: Heating
The Model 5532/5533 Chamber contains two (2), 250 Watt Electric Heaters (500 Watts total).
The Heater is an integral part of the Chamber, located inside the chamber workspace. Since
the Heater is already installed, there is no additional set-up required.
After turning “on” the “TEMP INCREASE” switch, the Microprocessor Temperature Controller
governs the operation of the Heating System.
1. The Microprocessor will determine the amount of heat needed to maintain the desired set
point. Power will be applied to the heater as a series of time proportioned pulses. .
2. The electric heating element and indicator light are located on white metal panel containing the
Fans located on the inside, rear wall (the heater is hidden from view).
3. The Heater Indicator Light will illuminate to indicate when power is being applied to the Heater.
(The Microprocessor LEDs will illuminate at the same time.)
A thermal safety switch (also on the panel) is connected in series with the heater. Power to the
heater will be cut off if the temperature within the chamber exceeds 135F (58C)

Operating Systems: Cooling
The Model 5532/5533 Chamber includes the ETS Model 5473-150W, 510 BTU/hr
Thermoelectric Cooling System as standard. Other cooling options include:
ETS Model 5473-300 1020 BTU/hr Thermoelectric Cooling System
ETS Model 5463 Liquid Carbon Dioxide Cooling System
ETS Model 5466 Liquid Nitrogen Cooling System
The Model 5473 Series of thermoelectric cooling systems utilize the Peltier effect to reduce the
temperature of a large heat sink. One or more 110 cfm fans circulate the air within the
workspace through the heat sink to continuously reduce the temperature. Very precise
temperatures can be maintained with this system by the microprocessor temperature
controller. The standard Model 5473-150 is capable of removing up to 510 BTU/hr (150
Watts/hr) from the Chamber. The Model 5473-300 is capable of removing up to 1020 BTU/hr
(300 Watts/hr) from the Chamber.
Operating Systems: Humidification
The Model 5532/5533 accomplishes humidification using an ETS Model 5482 Ultrasonic
Humidification System. The Humidifier is located inside the Chamber Equipment Enclosure. To
access the Humidifier, remove the large white acrylic panel on the right hand side of the
Chamber. The panel is held in place with eight (8) Phillips screws.
The Ultrasonic Humidifier is an open loop system that produces a fine water mist through
ultrasonic action. A blower fan forces the fine mist from the humidifier into the chamber.
Operating Systems: Dehumidification
The Model 5532/5533 Chamber includes a Desiccant-Pump Dehumidification System as
standard. As an option, the ETS Model 5478 Self-Regenerating Dehumidification System is
available.
Desiccant/Pump Dehumidification System
The Dehumidification System is closed loop designed to reduce the relative humidity in the
Model 5532/5533 Chamber to less than 10%. When paired with the Microprocessor Humidity
Controller, the humidity inside the chamber can be controlled, without disturbance, to within +/-
0.2% RH of the set point at the sensor.
The Dehumidification System includes a small air pump (located inside the Chamber Control
Cavity), 1 liter of Molecular Sieve (“MS”) desiccant in a clear plastic column (sits outside the
chamber), and ¼” O.D. tubing to interface the drying column with the pump. The tubing
connects to the chamber through the quick-connect fittings on the right side of the Chamber.
The desiccant column may be placed on top of, or next to, the Chamber.

D01042 Revision B - ETS 5532-5533 Startup - Page 12 of 15
The air pump is already connected to the Model 5532/5533 Microprocessor Humidity
Controller. All the user needs to do is connect the Desiccant Column into the system using the
provided ¼” OD Tubing.
The desiccant removes any moisture that is in the air. This dried air is then forced back into the
chamber.
VI. Calibration / Maintenance / Troubleshooting
Calibration
The only components of the Model 5532/5533 Controlled Environment System that require
periodic calibration are the Microprocessor Controllers and Temperature/Humidity sensor. It is
recommended that this section be returned to ETS for calibration. However, system calibration
can be checked by the user.
Place the sensor of a known, calibrated temperature and humidity meter as close as possible
to the System sensor. After the temperature and humidity within the chamber has stabilized,
compare the readings. They should be within the combined tolerance of the two measuring
devices.
To return equipment to ETS for calibration or repair it is first necessary to obtain a RMA
number. Call 215-887-2196.
To remove the Control Panel and sensor, first turn off and unplug the chamber, then gain
access to the operating systems compartment by removing the 8 screws holding the right side
panel in place. Unplug all connections to the front Control Panel. Loosen the 4 captive screws
holding the Control Panel and remove. Remove the sensor by loosening the compression
fitting inside the controlled environment section. Return both the Control Panel and sensor to
ETS.
Maintenance
The Model 5532/5533 requires very little maintenance. If the procedures in the previous
sections are followed the operating systems should operate trouble free. If the
dehumidification desiccant blue indicator dots turn a darker blue, that indicates the molecular
sieve material needs to be changed. After 500 hours of 5482 humidifier operation, we
recommend the basin maintenance procedure shown in the 5482 manual.
