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.
