Please read this guide carefully before installing and operating your
THERMAFLOW system.
The THERMAFLOW assembly is designed to cool and filter the oil required to
operate your hydraulic system. The oil is cooled by forcing air across cooling fins on
the heat exchanger. This system utilizes either an electric or hydraulic fan motor to
force air across the fins. The fan motor options are described below.
The Model SS675 has 2 fan motor options, Electric or Hydraulic. The Electric
fan motor option has a 12VDC cooling fan which is operated with a manual,
weather-tight toggle switch. This switch can be either wired hot or it can be wired
with the ground wire connected to an air operated on/off switch. Wiring the fan switch
through the air switch will give the operator automatic control. With the fan switch
“ON” the fan will cycle on when the PTO is engaged and then cycle “OFF” when the
PTO is disengaged. This option will also allow the operator to turn the fan off in cold
weather to bring the oil temperature up quicker. If you choose to wire the fan switch
hot you will run the risk of over-heating the hydraulic oil if you do not turn the fan
“ON”. The Hydraulic fan motor option has a fixed pressure compensated flow control
that automatically cycles the fan “ON” when the hydraulic system is
running and “OFF” when not running. This option comes plumbed from the factory.
Because different product pump applications require different speed and power
requirements, your THERMAFLOW system was custom engineered for a particular
application. If the system is operated beyond its designed capacity,
overheating and/or component damage may result.

STEP 1 POSITIONING & MOUNTING
The Model SS675 is designed to mount behind the truck cab across the frame rail sides.
A) Diagram A describes two mounting options available. Allow a minimum of 4” on both sides
of the unit for proper airflow.
STEP 2 INSTALLING THE PTO & HYDRAULIC PUMP
A) Install the PTO to the transmission and mount the hydraulic pump according to
the instructions included with the PTO.
HELPFUL HINT: If you are using a direct mount hydraulic pump/PTO combination,
be sure that the pump splines are well lubrication with a heavy grease. This grease
will prevent premature spline wear on the PTO and pump shafts. A small packet of
this grease is available through STAC Inc P/N 300980. Also available from both
MUNCIE and CHELSEA is a new option for a greaseable shaft. This option allows
you to grease these splines without pulling the pump off the PTO.

STEP 3 ELECTRICAL WIRING (Models with Electric Fan)
Models having a 12 VDC fan motor can be wired two different ways. Listed below are these
options.
OPTION #1 - FAN SWITCH WIRED HOT
This option wires the fan switch so that you can turn the fan on at anytime regardless
of whether the tractor is running or not.
ELECTRICALCONNECTIONS
REDWIRE:Connect to the positive (+) 12VDC battery terminal (20 Amps)
through circuit breaker (150153) provided in electrical kit (150525).
BLACKWIRE:Connect to the truck frame or to the negative (-) battery terminal.
For further illustration follow DIAGRAMB on Page 4.

OPTION #2 - FAN SWITCH GROUNDED THROUGH AN AIR SWITCH
This option wires the fan switch so that you will only be able to turn the fan on when
the PTO is engaged. This option will allow you to leave the fan switch “ON” so that
you have an automatic operation of the fan when the PTO is engaged. PTO
disengaged fan “OFF”, PTO engaged fan “ON” via an air switch.
ELECTRICALCONNECTIONS
REDWIRE:Connect to the positive (+) 12VDC battery terminal (20 Amps)
through circuit breaker (150153) provided in electrical kit (150525).
BLACKWIRE:Connect to air switch and frame ground.

STEP 4 HYDRAULIC PLUMBING
DIAGRAMS D & E show proper plumbing for Models SS675ER, SS675HR, SS675E3000ND
& SS675H3000ND. Please carefully read the Helpful Hints and Notes listed below before
beginning.
HELPFUL HINT: We recommend the use of minimum 1 1/2” suction hose. If the suction
hose is too small the hydraulic pump will cavitate and fail prematurely. A 3/4” pressure
hose is recommended for flows up to 25 gpm. A 1” pressure hose is recommended for
flows greater than 25 gpm. The 675 Series has a 2” suction port for high flow and tandem
applications.
NOTE: Be careful not to over tighten NPT threads. It is very easy to crack these
types of ports when tightening fittings.
