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.

Electrical Requirements
NOTE: For Lock Out / Tag Out plug the appropriate device into
the line cord.
The voltage and frequency requirements are specified on the serial tag on the rear of the
unit. Standard variances in frequency (+/-3Hz) and voltage (-5%, +10%) are allowed.
•Verify that the facilities voltage matches the requirement for the machine, which is
printed on the serial tag on the rear of the machine.
•The electric service wiring must be of a large enough wire gauge that the voltage is
maintained to the receptacle even when a full load is applied to the receptacle.
Additionally, the receptacle voltage should be measured while that receptacle is
under load.
•This unit has a NEMA 5-15P or 6-15P line cord, install an appropriate (NEMA 5-
15R or 6-15R) receptacle where the unit is to be run. (some 50 Hz machines are
shipped with no plug)
•Ensure the proper amperage circuit breaker is installed in the line and located near
the equipment.
•Plug in the line cord. (Avoid the use of long extension cords, these cause a
significant power drop between the wall receptacle and the machine.)
•When the unit is plugged in the amber POWER light on the front panel should
illuminate
Only qualified personnel should perform the installation of this
unit.

High pressure Bypass Hook-Up (Accessory)
The high pressure bypass allows the user to control the pressure of the process fluid going to
the application. This is particular can be useful if an application is sensitive to pressure such as
a glass jacketed reaction vessel.
1) Thread Part 1
onto the
process fluid
output and
tighten. The
barb should
face down.
(remember to
use pipe thread
sealant on all
metal to metal
connections)
2) Thread Part 2 onto the process
fluid input and tighten. The opening
should point toward left-hand side of
the machine (operators left when
looking at the control panel).
3) Take Part 3,
remove the
coupling and
thread it onto
Part 2 as shown,
tighten.
4) Pull the insulation on
Part 3 back as shown.
Tighten the coupling.
5) Slide the hose
from Part 3 all
the way onto the
hose barb on
Part 1. Position
the hose clamp

13
Connect to the Process
FTS provides input and output connections for the
process fluid. To tie these lines into your process,
you will need:
•1/4” Fittings for 1/4” male pipe thread on the
Fluid I/O ports (3/8” Fittings for 3/8” male pipe
thread on the Fluid I/O)
•3/8” ID tubing is recommended (1/2”ID
tubing for RS75)
•Pipe Insulation (Closed cell pipe insulation
will work for most applications. It can be
purchased from any local refrigeration or
plumbing supply house.)
•Glue seams of pipe insulation
•Teflon tape pipe sealant to seal all fittings
Always use caution when handling fluids, filling or draining the
system reservoir, or working in or around the chiller. Always
wear protective eyewear when operating the chiller.
Add Fluid
Once the fluid loop that runs to your application and back is in
place and sealed, fluid can be added to the reservoir. The
system can then be primed.
•Remove reservoir lid
•Fill reservoir to 1” (2.5cm) from the top and replace the lid.
•Press the I/O button (the pump will begin circulating fluid, if
more fluid is need to fully prime the process, immediately press
the I/O button to stop the pump. Add more fluid, tighten lid and
press the I/O button. Repeat this process of cycling the pump
and adding fluid until the system is fully primed.
Your unit is now fully installed and ready to operate.

15
NOTE: When changing setpoint, loosen the red vent screw
on the reservoir lid to accommodate for the expansion /
contraction of the process fluid. Once the chiller stabilizes
at a setpoint, tighten the red vent screw. This will help
prevent excess evaporation of the fluid, as well as
preventing atmospheric moisture from condensing on the
fluid.
If using a High Pressure
Bypass, take off the insulated
valve cover. Use the brass T-
Handle to adjust the operating
pressure of the system to the
desired levels.
