CONTAINERIZED KITCHEN (CK)
OPERATION UNDER UNUSUAL CONDITIONS
Draining the Water System
If freezing conditions are possible while the CK is packed for transport, or the kitchen is to be
left set up but unheated during possible freezing conditions, drain the water system to prevent
damage.
1. Turn off the water pump and water heater at the appliance control box.
2. Disconnect and drain the water supply hose. If packing the kitchen for transport, coil the
hose, connect its two ends together, and store it on the lower shelf in the front of the sink
assembly.
3. Open the hot and cold water faucets to release the pressure in the system. Leave the
faucets open.
4. Drain the cold water line into a pan, bucket, or other container by opening the drain valve at
the back of the sink assembly.
5. Drain the water heater into a suitable container by opening the water heater drain valve.
6. With both drain valves open, turn on the water pump for several seconds to purge the pump
of water. Turn off the pump when there is no sign of water coming from the drains.
7. If necessary, slightly tilt the sink assembly to drain any water remaining in the sink bowl and
drain pipe.
8. Disconnect the interior drain hose from the sink assembly and drain it into the floor drain. If
packing the kitchen for transport, disconnect the hose from the fitting on the floor drain, coil
it, and store it on the shelf in the back of the sink assembly.
9. Disconnect and drain the external drain hose. If packing the kitchen for transport, coil the
hose tightly and store it in the lower shelf in the front of the sink assembly.
10. Ensure that the hot and cold water lines and the water heater are completely drained, then
close the drains and faucets.
FORDING AND SWIMMING
In the packed-out configuration, the CK is not watertight. It should never be submerged in any
depth of water or equipment damage may result. When mounted on a trailer, hard-bottom water
crossings no deeper than approximately 2 feet can be forded. When in doubt, refer to Unit
Standard Operating Procedures.
INTERIM NUCLEAR, BIOLOGICAL, AND CHEMICAL (NBC) DECONTAMINATION
PROCEDURES
When an NBC attack is expected, and time allows, the kitchen should be packed for transport
per WP 0006 00 until the threat of attack is over. If an NBC attack occurs, the unit must be
decontaminated before use in accordance with FM 3-5.
JAMMING AND ELECTRONIC COUNTERMEASURES
The CK is not affected by jamming or electronic countermeasures.
