9. Each hose assembly is 50' (15 m) long.
maximum combined length of 300' (92 m) can
be used, in addition to a 15' (4.6 m) whip hose
assembly.
The whip hose assembly is smaller in diameter,
which makes maneuvering the hose easier for
the operator.
The fluid hoses are marked ISO or RES and
are oppositely coupled to prevent incorrect
connection, which can cause fluid crossover
and permanently damage to thehose. Refer to
Figure 1.
Connecting the 50' (15.2 M) Hoses
1. Connect the corresponding fluid hoses of
each 50' (15.2 m) assembly. See Figure 1.
2. Gently bend the slack in the heat tape on
both sides of the tape connectors as shown
in Figure 1.
3. Couple the heat tape connectors.
CAUTION
The bend in the heat tape helps prevent strain on
the tape wires at the connectors, which can cause
wires to pull loose from the connectors when the
hose is moved or coiled.
Do not wrap the heat tape around the hoses as
this also causes strain.
4. Cut the uncoupled air hoses (B) to a length
that will be easy to couple to the next air hose.
See Figure 2.
5. Attach a coupling to the air hose.
a. Slide the male end of the sleeve (A)
over the hose (B).
b. Grease the barbed end of the stud (C)
and push it into the hose until it seats
properly.
c. Tighten the sleeve onto the fitting until
the sleeve bottoms on the fitting.

6. Check the continuity of the heat tapes.
a. Use an ohmeter to check the electrical
resistance of the two outer prongs of
the connector (D) that attaches. to the
heated hose control.
The resistance for the various lengths
of coupled hose assemblies is given in
the following coupled hose chart.
Coupled Hose Length
315' (96 m)
215' (66 m)
115' (35 m)
65' (20 m)
50' (15.2 m)
See Figure 3.
Resistance Range
11-15 olms
20-25 ohms
37-46 ohms
65-80 ohms
84-124 ohms
