chemical systems, polyurethane foam chemical systems and some specific two-component
epoxy systems.
Principal Heating System
The Proportioner consists of one (1) independent Material Heater without internal seals. The
Heater has six (6) Heating Elements rated 1250 watts each giving the Proportioner a total
heat of 7500 watts and the necessary control and safety components for their precise
operation. The Material Heater design allows a temperature differential (ΔT) of 53º F (12º C)
and material application temperatures of up to 190º F (88 C) under normal ambient
temperatures.
Hose Heating System
The system is designed with a 3 KVA (90 V) Isolation Transformer that enables effective
heating of up to a total hose length of 310 ft (93 m). The system includes an innovative hose
heating concept in which the continuous braid tinned-copper jacket is distributed evenly
around the circumference of the hose providing a uniform heating watt density and precise

Heated Hose Installation
CAUTION! The material delivery Heated Hoses are color coded Red and Blue
allowing the user to recognize them. The Red corresponds to the Isocyanate
(Iso “A”) and the Blue to the Polyol (Poly “R”). To avoid connection errors the
Coupling Connections of the Iso “A”and Poly “R” Heated Hoses are also
different sizes, which makes it difficult to swap connections.
NOTE! The material delivery Heated Hoses are caped at the ends to prevent
absorbing moisture. Do not remove caps until the Heated Hoses are going to
be installed on the proportioner.
1. Lay out all the Heated Hose assemblies end to end aligning the Iso (Red) and Poly
(Blue) and connect the respective Coupling Connections using the appropriate
sized open-end wrench after ensuring Heated Hose assemblies lay flat.
CAUTION! Take care to not cross-thread or over-tighten the Coupling
Connections. Thread sealant tape or compound is not required for this tapered
seat Coupling Connections.
2. Connect the material Heated Hoses to the outlets of the respective Heater
connections i.e. Iso “A” Heated Hose to the Iso “A” Heater connection and the Poly
“R” Heated Hose to the Poly “R” Heater connection ensuring the Heated Hose
assemblies lay flat.
3. Connect Air Hose Coupling Connections.
4. Connect the Heated Hose power wires to the “Fast-Lock” Connector coming from
the Hose Heat Transformer as follows:
a. Loosen the Socket Head Set Screw to allow insertion of the Heated Hose
electrical wire Terminal.
b. Insert the Terminal into the “Fast-Lock” Connector Body.

NOTE! A good practice is to add some dielectric grease (Permatex 67VR or
equivalent) to the outside of the Terminal prior to insertion.
Repeat the above steps to connect the “Fast-Lock” Connectors that you will find on all
Heated Hose power wire. NOTE: All PMC heated hose wire is # 6 AWG.
CAUTION! Ensure the proper mechanical and electrical connections of the
Heated Hoses are made to avoid possible material leakage and hose heat
problems.
5. It is recommended the TSU be installed between the last section of Heated Hose
and the Gun Whip. Carefully straighten the sensing wire, inserting it in the Iso “A”
Heated Hose and tighten fluid fittings with appropriate sized open-end wrenches.
CAUTION! To protect the TSU sensor, you must 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.
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.
