4. For hoses that include the standard braided
protective scuff cover, unroll excess cover
over hose and electrical connections. Tape
securely.
5. For hoses that include Xtreme-Wrap pro-
tective scuff sleeve, pull just enough
excess length over hose and electrical con-
nections. Tape securely.
NOTE: Xtreme-Wrap protective scuff sleeve
will shorten in dry conditions. Use only as
much length as necessary to cover connec-
tions and allow excess to remain slack.
Operation
1. Connect air hose (3) to main air supply, if
equipped.
2. Connect to spray gun. NOTE: For best
handling of gun, see page 13 for proper
hose connection.
3. Connect whip air hose to gun air inlet if
equipped. See gun manual.
4. Follow setup, startup, and operation
procedures in proportioner manual.
Maintenance
1. Before disconnecting or repairing hoses,
relieve all fluid pressure and shut off electri-
cal power to proportioner. See proportioner
operation manual.
2. Be sure fluid is cool before disconnecting
hoses.
Instructions for Replacing
Individual A or B Hose
Before disconnecting hoses, relieve all fluid
pressure and shut off electrical power to pro-
portioner. See proportioner operation manual.
Disconnect electrical wire from connectors
(12). Disconnect fluid hose and remove from
bundle.
Install new hose in bundle, wrapping around
other fluid hose and air hose. Connect fluid
hoses, see page 14.
Wrap all connections with electrical tape, see
page 22.
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.
