ANNOVI REVERBERI TRI-PLEX PLUNGER PUMP:
Unit undergoes extensive testing at the time of manufacturing. Always check pump oil just like the engine oil
and use recommended oil for adding or changing. AR Tri-Plex RRV Model pumps are tested to 2000 hours of
use under standard and normal maintenance as outlined in this manual. Pump under warranty by
manufacturer. Refer to Warranty Policy for details. Rebuild kits are available for these AR RRV High Pressure
Tri-Plex Industrial Grade Pumps. Call Lifan Power USA for further details and information.
Do not run Pressure Washer without proper inlet water supply to high pressure pump and for more than 1 minute
without depressing trigger on gun to circulate water to avoid damaging pump.
USAGE IN HIGH ALTITUDE REGIONS:
In regions with high altitude, the standard carburetor produces overly dense combinations of fuel and air, which result in
decreased engine performance and increased fuel consumption. To maintain high engine performance at high altitudes,
install a high altitude carburetor main spray nozzle and re-‐‐adjust the adjusting screw for idle speed. For usage in regions
with an altitude of over 4,527ft (1380m), contact your dealer to replace the standard carburetor and make needed
adjustments in advance. Even with a proper high altitude carburetor spray nozzle installed in the engine, the power
output of the engine will drop about 3.5% with every 1000ft (305m) increase in altitude. If the standard carburetor jets
are not replaced and adjusted for usage in high altitude, the increased altitude effect will be even more severe.
NOTE: Usage of the water pump in regions with lower altitude than the high altitude carburetor spray
nozzle is applicable, may result in decrease of engine performance. The engine may become overheated
and over-
­­ lean combination of fuel and air produced, may cause severe damage to the engine.
