SAFETY AND HANDLING
4
The TSU has been designed and built for the application of polyurea chemical systems,
polyurethane foam chemical systems, and some two-component epoxy systems.
Always use liquids and solvents that are compatible with the unit. If in doubt, consult your PMC
Distributor.
When working with the TSU, it is recommended that the operator wear suitable clothing and
elements of personal protection, including, without limitation, gloves, protective goggles, safety
footwear, and face masks. Use breathing equipment when working with the TSU in enclosed
spaces or in areas with insufficient ventilation. The introduction and follow-up of safety
measures must not be limited to those described in this manual. Before using the TSU, a
comprehensive analysis must be made of the risks derived from the products to be dispensed,
the type of application, and the working environment.
To prevent possible injury caused by incorrect handling of the raw
materials and solvents used in the process, carefully read the
Material Safety Data Sheet (MSDS) provided by your supplier.
Deal with the waste caused according to current regulations.
To avoid damage caused by the impact of pressurized fluids, do not
open any connection or perform maintenance work on components
subject to pressure until the pressure has been completely
eliminated.
Use suitable protection when operating, maintaining or being present
in the area where the equipment is functioning. This includes, but is
not limited to, the use of protective goggles, gloves, shoes and safety
clothing and breathing equipment.
The equipment includes components that reach high temperatures
and can cause burns. Hot parts of the equipment must not be
handled or touched until they have cooled completely.
To prevent serious injury through crushing or amputation, do not
work with the equipment without the safety guards installed on the
moving parts. Make sure that all the safety guards are correctly
reinstalled at the end of the repair or maintenance work of the
equipment.

INSTALLATION
CAUTION! Connecting the TSU between the first and second section of
Heated Hose results in the TSU sensing the material temperature exiting
the Heater and not the inside of the Heated Hose near the Spray Gun.
CAUTION! To protect the TSU sensor, pay special attention not to kink
or excessively bend the Heated Hoses. Do not coil the Heated Hoses
with a diameter of less than 4 feet (1.22 meters).
*Recommended order of connections
1. It is recommended that the TSU be
installed between the last section of
Heated Hose and the Gun Whip.
2. Before fastening all hoses, install the
insulation (not shown) onto the hoses.
3. Carefully straighten the sensing wire
and insert it into the Iso (A) Heated
Hose
4. Tighten all fluid and air fittings with
appropriate sized open-end wrenches.
5. Secure the RTD connectors
6. Slide the insulation over the TSU.
