2-9. OPERATING PROCEDURES FOR MODEL RAK-15 (Continued)
NOTE
The latch self-locking mechanism engages automatically with an audible
"click" when the operating lever is in the "fully-down" position.
WATER SPILLAGE. Always ensure that the cover is properly closed and
latched before operating the HWR or at any time that the host vehicle is
mobile. Failure to secure the cover can result in the accidental spillage of
water.
CAUTION
OVERHEATING. To avoid overheating, do not operate the HWR
without water in the outer container. Overheating can result in the
HWR becoming non-operational.
(12) Set the LO/OFF/HI switch (1) to HI and verify that the POWER ON lamp (2) and
HEATER ON lamp (16) are both on.
(13) Water (and rations) have been heated to the selected temperature when the HEATER
ON lamp (16) goes off again.
NOTE
When the water has heated, the rations may still require heating and a
longer warm-up time should therefore be allowed. Leave the LO/OFF/HI
switch set to LO or HI for as long as is needed, the water will be
thermostatically maintained at the selected temperature and the rations
will continue to be heated.
(14) If further heating of rations is not required, set the LO/OFF/Hl switch (1) to OFF and
verify that the POWER ON lamp (2) is off.
