Inspection
This merchandise was carefully packed and thoroughly inspected before leaving our factory.
Save all packing material if apparatus is received damaged.
Responsibility for its safe delivery is assumed by the carrier upon acceptance of the
shipment, therefore, claims for loss or damage sustained in transit must be made upon the
carrier by recipient as follows:
Visible loss or damage
Note any external evidence of loss or damage on the freight bill, or express receipt, and have
it signed by the carrier's agent. Failure to adequately describe any such external evidence of
loss or damage may result in carrier's refusing to honor your damage claim. The form
required to file such a claim will be supplied by the carrier.
Concealed loss or damage
Concealed loss or damage means loss or damage which does not become apparent until the
merchandise has been unpacked and inspected. Should either be discovered, make a written
request for inspection by the carrier's agent with 15 days of the delivery date; then file a claim
with the carrier since the damage is the carrier's responsibility. By following these instructions
carefully, we guarantee our full support of your claim to be compensated for loss from
concealed damage.
Do not -- for any reason -- return this unit without first obtaining authorization. Please
supply nameplate data, including model number and serial number, in any
correspondence to the manufacturer.
WARNING
DO NOT STORE OR PROCESS FLAMMABLE MATERIALS
This unit is not designed (nor is it intended to be used) for the
purpose of processing or storage of materials that may
contain volatile flammable solvents or that may emit
flammable vapors during processing or storage.

Installation
Physical Location
The area where you place the unit should be smooth, level, and capable of safely supporting
the weight of the machine. Space should be provided so that air can properly circulate around
the unit. If obstacles are blocking the airflow, the compressor may overheat. This reduces
performance, and can lead to early compressor failure.
The environment should be well ventilated to prevent excessive build up of heat. Normal
room ventilation is usually adequate.
Ambient Air Requirements
This unit is designed for operation in a normal indoor environment. (Systems should not be
mounted outside or otherwise exposed to the elements). The environment should be free
from air containing large amounts of moisture, salt or sulfur. If your system utilizes an air-
cooled condenser, the fan in the system draws ambient air across the condenser (radiator) to
cool the refrigerant.
The ambient air temperature requirements are:
55°F to 69°F (12°C to
21°C) Acceptable
70°F to 75°F (21°C to
24°C) Ideal
75°F to 80°F (24°C to
27°C).
Acceptable, but a reduction in the cooling capacity of the
unit is to be expected (about a 1% cooling capacity
reduction per degree above 72°F).
80°F to 85°F (27°C to
29.5°C) Expect reduced reliability. Warranty may be voided.
Over 85°F (Over
29.5°C) Not Acceptable. Warranty will be voided.

Selecting a Process Fluid
There are other fluids available, but to avoid potential application problems and
to speed troubleshooting; it is suggested that one of the fluids mentioned above
be used. DO NOT USE AUTOMOTIVE ANTI-FREEZE (it contains clotting
agents) If for some reason one of the above fluids is not suitable, and you select
a different one, be sure that it has a viscosity of less than 20 centistokes over the
full temperature range of the unit. NOTE: All of the above mentioned fluids have
viscosity of less than 20 centistokes across their useable temperature ranges.
Since most systems have capability to achieve temperatures below 0°C, water should
not be used as a process fluid.
This recirculator is designed for operation with a host of industry standard fluids.
Which fluid you choose will depend partly on what temperature range you require.
Ethylene Glycol and water (60/40 mix) is an inexpensive and readily available fluid for
–25°C to +60°C. If you require a fluid outside this temperature range, FTS suggests
using HT-30 Silicone Oil for –60°C to +100°C.

Process Fluid Properties
Expansion/Contraction
It is important to note that some fluids expand as much as 14% from +25°C to +125°C. Do not confuse contraction
of the fluid for fluid losses. Also, open the red vent screw on the reservoir lid when changing the setpoint (the
temperature the unit controls at).
Fluid Creep
Galden and similar fluids are very 'thin' and any non-sealed connection in the fluid loop will leak.
Dissolved Gases
At room temperature the fluid contains dissolved gas. As the fluid temperature is increased the amount of
dissolved gas decreases dramatically, causing excess gas to be released from the fluid. This release of gas
should not be mistaken for boiling of the fluid.
Water Solubility
Process fluids are water-soluble. After long periods of operation at low temperatures, water from the air will
condense on and mix with the fluid. this decreases the performance of the system. To remove the excess water,
warm the fluid to room temperature and pump the fluid through a molecular sieve or desiccant material.
Alternately, simply run the system at temperatures over 100°C, this will boil off any water present in the fluid. (Only
applies to the systems that are capable of temperatures over 100°C)
Low surface tension and high vapor pressure
This means that the fluid evaporates very easily and that any improperly sealed joints will leak. Close the red vent
screw on the reservoir lid to prevent excessive evaporation of the fluid, but remember to open the vent screw when
changing setpoints (the fluid expands and contracts with temperature changes).
Fluid Creep
Fluids will find any non
-
sealed connection.
