THAWING THE LWP
CAUTION
Never thaw out the LWP by exposing it directly to a heat source such as the discharge end of
a personnel heater, propane torches, etc.
After being exposed to the freezing weather, the LWP should be thawed out by placing inside a heated tent for 2
hours. After which, inspect the unit for any sign of frost or frozen components. Allow more time for complete
thaw if necessary. Close all drain valves before operation.
LONG TERM COLD WEATHER STORAGE
For long term storage in the freezing weather,
1. Follow the above cold weather drain procedure.
2. Follow the preservation procedure described in WP 0013 00 for both membranes and the diesel
engine.
