Maintenance
1. Nozzles. Nozzles should be checked regularly to ensure the best misting performance. The mist or
fog should emit from the nozzle in an even cone shape. If the mist is not an even cone shape the nozzle
needs to be cleaned or replaced. To clean a nozzle, first remove it from the misting ring. Disassemble
the nozzle and soak the nozzle tip and impeller in ZEP, CLR, or vinegar. Do not soak the spring or the
body of the nozzle. After soaking, rinse with water and reattach to the misting ring, do not use tools.
The nozzles should function properly when screwed in by hand.
2. Pump. The pump requires an initial oil change after 50 hours of service, and additional oil changes
every 3 months or 500 hours. Use 8.5 oz of ISO68 hydraulic oil. When changing the oil disconnect the
electricity to the system. Do not run the pump without oil in the crankcase. Check the seals and valves
for wear after 1000 hours. Check immediately if the systems performance decreases.
3. Filters. The filters should be checked frequently and replaced if needed. The filter life depends on
the water source. If the filter is dirty replace immediately because it is restricting water flow to the
pump and may damage the system. To check the filter, simply unscrew the housing from the top
bracket. When replacing the filter it is also good practice to clean the housing with bleach. Use a few
tablespoons of bleach mixed with water and scrub the inside of the housing. Make sure the o‐ring is in
place when reattaching the housing to the bracket, then hand tighten and check for leaks.
4. Storage. When storing the system for more than a few days or transporting the system, it is
important to drain the water. Draining the water prevents calcification problems or the formation of
algae. Drain the system by opening the evacuation valve and relieving the pressure in the system. It
may be necessary to tilt the system to drain all the water. Also drain the filter housing to preserve the
filter. Store the unit in a dry location with ambient temperature. Avoid areas that are subject to
excessive heat, dust, humidity, freezing, or damage from nearby equipment. If freezing conditions are
possible flush your pump with a 50/50 solution of anti‐freeze/water. Also drain any supply hoses.
For initial operation after a long duration of non‐use it is necessary to flush the system of particles.
Remove the nozzles from the nozzle rings and place the system in a water safe environment. Power up
the system and allow water to flow through the nozzle openings for a few seconds. After flushing the
system, reattach the nozzles and tightening by hand.
