(e) Turn PUMP HEAT/SUMP HEAT ON/OFF (24) switch to OFF.
(f) Connect heat lamp power cable (32) to outlet (33) on ROWPU van.
(g) Turn PUMP HEAT/SUMP HEAT ON/OFF (24) switch to ON. This will turn on pump heat Iamps and van sump
heat tracing.
(h) Do not connect dispensing hoses until ready to start distribution pump. Keep dispensing hoses reside
ROWPU van.
CAUTION
Failure to properly warm the pump before starting wiII result in an immediate freeze up of
the distribution pump and possible damage.
NOTE
When distribution pump is first started, lift cover and be sure pump is rotating by looking at
the shaft between the pump and motor. If not, stop immediately and allow heat lamp to
warm pump.
f. Initial Adjustments, Checks, and Self Tests. See paragraph 2-15 For first start-up or start-up from secured or

ON-OFF switch to ON position if not already accomplished.
NOTE
If hoses were rolled and stored in ROWPU, normal procedures may be followed.
(b) If hoses were not rolled and stored, then roll the hosing under foot breaking loose any ice inside.
(c) Disconnect raw water intake hose at ROWPU and place end away from immediate area
(d) Prime and start raw water pump. Allow flow to blow ice from end of the hose. The hose may have to be
