1 INTRODUCTION
1.1 SAFETY WARNINGS
THE PHRASE WARNING IS USED WHERE THERE IS A HIGH
PROBABILITY OF PERSONAL INJURY OR DEATH SHOULD
THE PROVISIONS HIGHLIGHTED BE IGNORED. IT IS THE
DUTY OF BOTH THE INSTALLER/OWNER AND OPERATOR
OF THE EQUIPMENT TO BE FAMILIAR AND COMPETENT
WITH THE OPERATION AND USES OF THE PRODUCT.
HELP MAY BE SOUGHT FROM THE MANUFACTURER.

Cryogenics Microprocessor Based Cryochillers INTRODUCTION
telemark.com 8 of 81
Rev 1.0.9
WARNING
1) The system contains specific hazards, which present a
significant danger to personal safety:
(a) High voltage electrical components and high-pressure
refrigerant gases, which are a significant frostbite
hazard.
(b) Refrigerant gases, which will cause asphyxiation in
confined areas.
(c) Refrigerant gases, which if exposed to high
temperatures decompose to form very toxic by-
products –never smoke in the vicinity of a UNIT
or any other similar system including the gas
cylinders.
(d) Water in close proximity to high voltage electricity.
(e) Hot and cold surfaces which represent a significant
burn / frostbite hazard.
WARNING
The system contains gases under pressure, which may
constitute both a frostbite hazard and a burn hazard.
Refrigerant gases are known asphyxiates and are mildly
narcotic. Precautions must be taken, and work must only be
carried out by suitably qualified personnel.
WARNING
Removal of any panels other than the front door will expose
the operator to high voltage components, which may result
in a fatal electrocution.
WARNING
During installation there is the potential to be exposed to
high voltage components (up to 400v ac), which may result
in a fatal electrocution.

Cryogenics Microprocessor Based Cryochillers INTRODUCTION
telemark.com 9 of 81
Rev 1.0.9
WARNING
Units must always be operated with a suitable ground/earth
line. Failure to comply may result in fatal electrocution.
Never tamper with or remove any ground/earth connection
from inside of the machine.
WARNING
Isolate system before connection. Ensure the connection
cable used is compliant with local electrical requirements.
Cabling within the unit is tri-rated to CSA/UL/CE norms.
There must be three power wires and one ground wire;
there is no neutral line. Feed cable through gland and
terminate at main system isolator, having first removed the
protective cover. Ground the UNIT at primary ground point.
WARNING
Failure to replace isolator cover exposes operators to
potentially fatal electrocution. It is essential this primary
protection always be in place before the system is
energized.
WARNING
Always isolate the system through the main circuit breaker
before attaching the remote control. When in remote
operation take additional care to prevent personal injury.
WARNING
Failure to leak test the system as a whole, may result in the
catastrophic release of refrigerant, which presents a very
high risk from frostbite and or asphyxiation. See emergency
shutdown procedures and material safety data sheet for
guidance.

Rev 1.0.9
WARNING
The refrigeration system contains a mixed blend of
refrigerants and polio-ester oil. These do not present
acute health risks, but it is essential that the following
basic precautions are followed:
a. Always wear eye protection.
b. Always wear surgical type rubber or latex gloves.
CAUTION
CAUTION
Telemark will not be responsible or liable for either direct
or consequential personal injury or loss claims arising
from the misuse of the product.
CAUTION
If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment
may by impaired
CAUTION
It is the responsibility of the user to make sure all local,
county, state and national codes, regulations, rules, and
laws related to safety and safe operating conditions are
meet for each installation. The safety of any system
incorporating the equipment is the responsibility of the
assembler of the system.
The phrase “Caution”indicates a risk of damage to
the product or associated plant and machinery if the
provisions are not followed carefully.

Rev 1.0.9
CAUTION - HOT SURFACE
High temperatures are generated during normal
operation. Avoid contact with exposed pipework as this
can get hot during normal operation.
CAUTION - COLD SURFACE
Freeze Burn Risk. Very low temperatures generated
during normal operation. Avoid contact with exposed
pipework.
CAUTION - PRESURISED GAS
Unit contains pressurized gas. Do not open hand valves
until system is connected to a Cryo-coil, which has been
checked for leaks. Do not connect the system to other
systems unless their design and application has been
approved by the manufacturer
CAUTION - HAND VALVES
Closure of the hand valves while the system is at
cryogenic temperatures may damage the valve seats and
invalidate the systems warranty. It must only be
attempted on a cryogenically cold system in the case of
an emergency, which is causing gross leakage from the
Cryo-coil or refrigerant lines.
1.2 WARRANTY
Telemark Cryogenics Cryochiller products are warranted to be free from defects in
materials and/or workmanship under normal usage until warranty effective date listed on
serial number label. Telemark Cryogenics’obligation under this warranty is limited to the
repair or replacement, at its option, of any parts, which upon examination at the
Telemark Cryogenics factory or by an authorized sales/service representative, shall
appear to have become defective. Correction of defects by repair or replacement shall
be either at the Telemark factory or in-situ by an authorized service representative. The

The user should read this manual in its entirety before carrying out any work and or
operation of a Telemark Cryochiller.
1.4 INTENDED USE OF THE EQUIPMENT
Water vapor Cryochiller is a device that improves the performance of vacuum pumping
due to the efficient trapping of water vapor in the chamber.
Classically a Cryochiller is used with an evaporative surface (Meissner/cryo-coil), which
is located within the vacuum chamber. When in this configuration a Telemark
Cryochiller is an ultrahigh performance vacuum pump capable of pumping water vapor
and other condensable gases at speeds far more than conventional vacuum pumps.
A Telemark Cryochiller couples speed with a sophisticated computer control package
which includes a simple and adaptable user interface with isolated inputs/outputs and
Ethernet comms package as standard. RS232 and RS485 serial communication options
are available.

Rev 1.0.9
The ranges of tasks to which your Cryochiller can be applied are not limited to pumping
water vapor in vacuum. Many are used as substrate coolers (chuck coolers) or other
applications where a continuous level of high-power cooling in the range –100 to –
150oc is required.
1.5 STANDARDS
The device is compatible in terms of electromagnetic compatibility and safety standards.
Applicable standards:
EMC: DIRECTIVE 2014/30/UE - STANDARD EN 61326-1:2013
LVD: DIRECTIVE 2014/35/EU - STANDARD EN 61010-1:2011

3 INSTALLATION
Safety and Cautionary Notes for Installation.
WARNING
Failing to leak test the system may result in the catastrophic
release of refrigerant, which presents a very high risk from
frostbite and/or asphyxiation. See emergency shut down
procedure and material safety data sheet.
WARNING
The system uses high voltage (208 or 415VAC) and high-power
components. To avoid the possibility of a fatal electrical shock
always isolate the unit from the mains supply before working on
the system. A qualified technician, as for all high-power
electrical connections, should carry out the electrical work
