b) Turn ON the main switch and hose heat circuit breaker and adjust the power
control (clockwise) to 45-50 amps;
If hose heat is restored, then the fault is within the gun whip hose.
If hose heat is not restored, adjust the power control counterclockwise until
the ammeter reads zero, then turn OFF the hose heat circuit breaker, and main
switch and proceed with the steps below:
WARNING: T
HE HOSE HEAT TRANSFORMER VOLTAGE MUST BE SET TO MATCH THE HOSE
LENGTH IN USE
. T
OO MUCH POWER WILL CAUSE THE HOSE HEAT CIRCUIT FUSE TO FAIL

OO
LITTLE POWER WILL RESULT IN INSUFFICIENT HOSE HEATING
.
c) Adjust the tap settings of the hose heat transformer to match the next shortest
length of heated hose (see Hose Heat Power Pack on page 15).
d) Unplug the next set of Power-Lock connectors and plug the hose jumper plug
into the last “upstream” segment of hose.
e) Turn ON the main switch and hose heat circuit breaker and adjust the hose
heat power control to 45-50 amps;
If hose heat is restored, then the fault is within the last unplugged segment of
hose.
If hose heat is not restored, adjust the hose heat power control counterclockwise
until the ammeter reads zero, then turn OFF the hose heat circuit breaker and main
switch and repeat Steps c) through e) until the fault is located.
5. DIGITAL HOSE HEAT SOLID STATE RELAY (SSR)- It is not possible to check
for normal operation of the SSR without electric power. Therefore, if all other
testing fails to determine the source of problem, assume the SSR is inoperative and
replace it.
IMPORTANT: In order for the Solid State Relays located inside the electrical
console to operate properly, their excess heat must be passed off to the heat sink
mounted on the console rear. The heat sink is cooled with exhaust air from the air
cylinder, thereby cooling the SSRs. Do not disconnect the ventilation hoses or cover
the heat sink, or obstruct air flow to the heat sink in any manner or damage to the
SSRs will result.
MANUAL HOSE HEAT CONTROL: - The automatic hose heating system can be
bypassed to allow for manual control of the hose heater. This feature will allow for
continued operation of the hose heating system in the event of signal or SSR failure.
To convert to manual control, proceed as follows:
a) Turn OFF the main switch. Switch OFF and lock out incoming power at the
source.
b) Adjust the tap settings of the hose heat transformer to match the next shortest
length of heated hose than that in use
(see Hose Heat Power Pack on page 15).
