COLD WEATHER OPERATION AND STORAGE
GENERAL
This work package contains information and instructions for the operation and storage of the Lightweight Water
Purifier (LWP) during cold weather conditions using the cold weather kit. If the ambient temperature is expected
to reach 32F or lower, the LWP must be operated in a heated tent and use electric thermal blankets on the
hoses where necessary.
The LWP will be set up within a heated general-purpose medium tent for operation. The only items outside and
exposed to the weather are the two reject hoses, raw water pump, raw water hoses (grey) and fabric hoses
(green) from the raw water pump to the settling tank. The COLD WEATHER KIT includes thermal blankets to
protect these items.
