2-16.
EMERGENCY PROCEDURES (CONT)
as instructed in paragraph 2-8b.
Special caution should be taken
because moving parts may be exposed.
(2) Fuel Line or Quick-Disconnect.
If the fuel line or quick-
disconnect become damaged, connect a temporary fuel hose to
carburetor fuel inlet barb.
Prime the carburetor fuel bowl.
Start
the water chiller and run in the normal operating mode (paragraph
2-8b.) .
(Because the fuel cooler will be bypassed, vapor lock and
fuel loss to the engine may occur during high temperature operation.)
CAUTION
Do not allow the water chiller to operate more
than ten seconds without water circulating
through the system.
Check the water outlet to
ensure water circulation, to prevent damage to
the water pump impeller.
It is protected by the
temperature sensor only when ignition switch is
in run position.
c.
Automatic Shutdown.
The water chiller is designed to shutdown
automatically when the water pump temperature sensor exceeds 1300F
(54.50C).
This safety feature is to protect the water pump neoprene
impeller from damage by running dry.
To reset the temperature
sensor, the water pump housing and/or water temperature must be
reduced below 1300F (54.5oC).
Water can be circulated through the
system by bypassing the safety sensors.
This can be accomplished by
placing the water valve in the RUN position and holding the spring-
loaded ignition switch (S3) in the START position.
When the water
temperature and/or pump housing temperature drops below 1300F
(54.5OC), release the spring-loaded ignition switch (S3) allowing it
to return to the RUN position.
CAUTION
Inlet water temperature should not be higher than
100OF (380C) in the water transfer mode.
d.
Water Transfer.
The water chiller may be used to transfer
(pump) water from one source to another at the rate of approximately
five gallons per minute.
This can be accomplished by connecting the
warm inlet hose to the water source and the recirculating (outlet)
hose to a storage container and operating the water chiller with the
water valve in the START positon.
