Operation
1. Connect air hose to main air supply, if
equipped.
2. Connect electrical connectors (12) to con-
nector from fluid manifold (M) or accessory
control box. See Connect Heated Hoses,
page 13. Connect hose cable (4) to cable
from proportioner fluid manifold or acces-
sory control box. Wrap connections with
electrical tape.
3. Connect to spray gun. See gun manual.
4. Connect whip air hose to gun air inlet if
equipped. See gun manual.
5. Follow setup, startup, and operation proce-
dures in proportioner manual.
Fluid Temperature Sensor
(FTS) Calibration
1. Before turning on the unit, ensure all hoses
and cables are properly connected. To
ensure that the FTS in the hose is at the
same temperature as the heaters, keep
heat off and store the hose FTS near the
machine for several minutes.
2. While holding down the temperature unit
button (Fahrenheit - “F” or Celsius - “C”)
turn the proportioner main power ON.
3. Hold the temperature unit button until tem-
perature is shown on the display. The fluid
temperature sensor is now correctly cali-
brated.
Do not operate a coiled hose. A coiled hose
creates uneven heat buildup which can result
in hose rupture and cause serious injury,
including fluid injection.
Maximum hose operating temperature is
180°F (82°C). If using hose without an FTS,
measure hose temperature to ensure it does
not exceed 180°F (82°C).
Hose must be properly supported to avoid
excessive strain due to weight, bending,
sharp edges, or stress caused by running
over a roof edge.
Fluids subjected to heat in confined spaces,
including hoses, can create a rapid rise in
pressure due to the thermal expansion.
Over-pressurization can result in equipment
rupture and serious injury.
Open a valve to relieve the fluid
expansion during heating.
Replace hoses proactively at regular
intervals based on your operating
conditions.
FIG. 16
Calibrate the FTS ONLY at initial startup
(the first time the unit is operated) and
any time the hose length changes.
