as viewed from right hand side.
(10) the refrigeration system contains a mixed blend of refrigerants and polio-ester oil. These
do not present acute health risks it is essential that the following basic precautions are
followed:
(a) always wear eye protection.
(b) always wear surgical type rubber or latex gloves.
(11) the system contains specific hazards, which present a significant danger to personal
safety
(a) high pressure refrigerant gases, are a significant frostbite hazard.
(b) refrigerant gases will cause asphyxiation followed by death 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 TVP or any other similar system
including the gas cylinders.
CAUTIONS
The phrase Caution indicates a risk of damage to the product or associated plant and
machinery if the provisions are not followed carefully.
(1)
Telemark will not be responsible or liable for either direct or consequential personal
injury or loss claims arising from the misuse of the product.
(2)
Unit contains pressurised gas. Do not open hand valves until system is connected to a
Cryocoil, 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.
(3)
Closure of the hand valves whilst 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 Cryocoil or refrigerant lines.
(4) Do not connect the TVP to an existing Cryocoil without insuring that the Cryocoil will
accept the operating pressure of the TVP system and that the whole system has been fully
leak checked. Failure to do so could damage the coil and the vacuum system.
(5)
The Cryocoil should be no less than 1/2 inch or 13 mm away from the chamber wall or
any other object including other parts of the Cryocoil. Failure to comply will reduce efficiency.
It is bad practice to mount the Cryocoil directly onto a metal plate.
(6)
Access to two sides must be maintained: The front/control panel and the right side
cooling water/refrigerant line/power/remote control points. No such requirements are
necessary for the left side or back of the TVP unit. Although a clearance of 70 mm to allow the
door to open fully is required on the left hand side of the unit.
(7)
The correct orientation of the flow is essential if the full potential of the unit is to be
realised:
Inlet to coil on the right }
Outlet from coil on the left }
(8)
The TVP is phase sensitive, if connected in the wrong orientation the unit will not
operate correctly. No damage can be caused by incorrect orientation of the phases.
(9)
Poor water vapour pump performance is often caused by poor insulation or by water
collection on the refrigeration lines.
