washing may create slippery surface on which a person may slip and
fall causing personal injury or death.
1. Wear suitable footwear to maintain a good grip on wet surfaces.
2. Do not stand on ladders or scaffolding.
3. Do not over reach or stand on unstable supports.
4. Keep good footing and balance and hold gun with both hands to control
kick back.
A. IMPROPER USE OF FITTINGS HAZARD
Do not operate the pump with improperly connected, sized, worn or
loose fittings, pipes or hoses. Operating the pump under these conditions could result in personal injury and property damage.
1. Ensure all fittings, pipes and hoses are properly rated for the maximum
pressure rating and flow of the pump.
2. Check all fittings and pipes for cracks or damaged threads.
3. Check all hoses for cuts, wear, leaks, kinks or collapse before each use.
4. Ensure all connections are tight and secure.
5. Use PTFE thread tape or pipe thread sealant (sparingly) to reconnect
plumbing. Do not wrap tape beyond the last thread, this will prevent tape
from becoming lodged in the pump or accessories.
6. Apply proper sealants to assure secure fit or easy disassembly when
servicing.
B. FROZEN LIQUID HAZARD
Do not operate the pump with frozen liquid. Operating the pump under
this condition could over pressurize and jettison the manifold from the
crankcase causing personal injury and property damage.
1. Store pump or pumping system in an environmentally controlled room
protected from freezing temperatures.
2. Follow procedures in TECH BULLETIN 083 to winterize pump.

D. BY-PASS OPERATION HAZARD
Do not operate the pump in by-pass for extended lengths of time.
Operating the pump under this condition can quickly cause heat buildup resulting in damage to the pump.
1. Route by-pass line to supply reservoir to dissipate heated by-pass liquid
into a large reservoir of cool water to reduce excessive temperature
build-up.
2. Route by-pass line to inlet of pump using a thermo valve in the by-pass
line or auto shut-off assembly that will sense temperature rise and either
by-pass or shut down system before damage occurs.
E. DRY OPERATION HAZARD
Do not operate the pump without water or liquid. Operating pump under
these conditions could result in damage to the pump.
1. Open all valves on inlet side of pump before starting operation to prevent starving the pump.
2. Do not exceed inlet suction pressure limit specified in pump Data Sheet.
3. Ensure inlet feed exceeds the maximum flow being delivered by the
pump.
4. Ensure all fittings, pipes and hoses are properly sized for the pump to
avoid restricted flow.
5. Review and implement all other recommendations appropriate for your
system from the Inlet Condition Check-List.
