2-12.
General. This section provides instructions for operating the pumping assembly in unusual conditions.
a.
Cold Climates. If freezing conditions exist (below 320F) water in lines will freeze If during extreme cold conditions
pumping assembly is shut down, open pump drain plug and allow pump to drain Open drain valves (1, Figure 2-
10) in control panel. For operation of equipment in cold temperatures, the choice of viscosity grade lubricating oil
is specified in LO 10-4320-315-12. Use ether start as cold start aid as follows (Figure 2-10).
(1)
Pull ETHER START handle (2, Figure 2-10) to inject one shot of ether into engine air cleaner line.
(2)
Push handle in to reset.
Figure 2-10. Cold Climate Operations
b.
Hot Climates. In hot climates, make sure engine receives adequate ventilation. Use the viscosity grade
lubricating oil specified in LO 10-4320-315-12.
c.
Dusty or Sandy Conditions. Protect pumping assembly from sand or dust as much as possible. Check air filter
restriction gage frequently.
d.
Salt Water Area. Check for rust formations weekly. Check all electrical contacts daily for evidence of corrosion.
