Overview of High‐Pressure Misting System
Thank you for choosing Hydromist as your provider for high-pressure misting systems. Hydromist is
committedto providing its customers with reliable high-pressure cooling systems engineered with
quality components to meet their cooling needs.
Hydromist’s high-pressure misting system provides superior cooling by combining small orifice misting
nozzles with a high-pressure pump to create avery fine mistor fog. This finemist will quickly evaporate
through a process called flash evaporation reducingthe temperature ofthe ambient air. Hydromist pairs
the misting system with durable fans to reduce the temperature in the desired location.
Start‐up and Operation Procedures
High-pressure misting systems require electricity and water to function properly. Electrical connections
are needed to provide power to the pump motor and the fanmotor. Use the proper electrical source to
ensure thesystem will operate correctly. The water should be supplied to the tank through the garden
hose connection on the back of the unit.
1. Connect the water supply to the 3/4” female garden hose adapter on the back of the unit.
Purge your hose or water line of debris before attaching it to the unit. The ideal water supply
should meet the following conditions:
• Flow rate of 1 GPM ormore
• Water less than 7.5pH
• Pressure between 15-75PSI
• Dissolved solid content less than 500 PPM
2. Connect the unit to a power supply.
This system is equipped with a NEMA 5-15 plug for 110 volt electrical connections. The amperage
requirements are located on the motor plates of both the pump motor and fan motor. Do not use
extension cords or other adapters for electrical connections unless the components are rated for
heavy duty outdoor use with at least 15A rating at 125V. Common household electrical systems
have plugs rated to 15 amps. Common household circuit breakers areoverloaded at 20 amps.
Consult a certified electrician if you are unsure about your powersupply.
WARNING
ELECTRICAL SHOCK HAZARD: Serious injury or death is possible.
Only connectthe power supply plug to a properly grounded receptacle.

3. Connect to water supply or fill water tank.
Once the hose isconnected tothe inlet at the backof the tank, turnon the water supply and allow the
tank to begin filling. The unit may be operated with the water supply connected or disconnected. The
approximate run time is 3 – 4 hours, depending on the on/off cycle settings used.
If operating withthe water supply disconnected, wait for the tank to fill up and then turn off the water
supply and disconnect the garden hose. When the tank is full a float valve will automatically shut off
the water supply inlet, stopping the tank from being over filled. The inlet valve will open when the
tank water level drops below full, and if there is a water supply connected, the tank will continue tofill
until water level rises andthe float valve shutsoff the inlet again.
The water tank has an auxiliary fill cap on the top of the tank.This capcan be removedto fill the water
tank with the exception that any water added to the tank this way will not be filtered by the built-in
water filter. It is strongly recommended that the garden hose inlet at the back of the unit always be
used to fill the water tank. Impurities in municipal water supplies may not be visible, and over time
can cause premature clogging of nozzles.
4. Purge air from the system.
During this process, a steady stream of water will exit from the misting ring, so besure to perform this
step in an area where water will not damage any property or goods.
Remove one misting nozzle from the top side of the misting ring. This will allow any air in the system
to be forced out and the system will fill with water. With the misting nozzle removed (and water in the
tank) activate the pump by pressing the “ON” button on the control panel. If the “Warning” light is on
you may need to reset the low water level indicator by pressing the “OFF” button. The red warning
light should go off and youcan now activate the pump. It will take approximately 30 seconds to purge
the air from theentire system. Once asteady stream of water is flowing from the misting ring, turnoff
the pump and install the misting nozzle back onto the misting ring. The misting system should now be
ready to operate. Test the system be turning on the pump and waiting a few seconds while pressure
builds up in the system. You will see the mist coming from the misting nozzles once the system is fully
pressurized. The mist should form a uniform cone shape when exiting the nozzle.If thecone is not
even, orif thenozzle appearsto be leaking, see the troubleshootingsection. Purging is typically only
needed during initial setup, and/or after extended periods of non-use.
5. Turning on the Fan. Cool Caddie units have an integrated power cord to supply power to the fan.
The male and female ends of the plug must be connected for the fan to operate.
Figure 1 - The Fan plugs into the power cord attached at the base of the unit.
To begin operation of the fan, turn speed selection knob on the fan to your desired speed. Fans have
three different speeds and an oscillator that may be switched ON or OFF. Fan speed may also be
controlled by the control panel knob on the back of the tank. Place the misting system inthe desired
location and lock the wheelin place to prevent the unit from moving during operation.

6. Turning off the system. Turn the fan speed control knob to the “OFF” position. Turn off the
pump by pressing the “OFF” button on the back of the unit.
Maintenance
1. Nozzles. Always turn off the pump before removing the misting nozzles.
Nozzles should be checked regularly to ensure goodmisting performance. The
mist 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 themisting ring. Disassemblethe nozzle and soak the nozzle tip
and impeller in vinegar or a household cleaning product used for dissolving
calcium, lime, and iron oxide deposits (commonly known as CLR®). Do not soak
the spring or the bodyof the nozzle. After soaking,rinse with water andreattach
to the misting ring, do not use tools. The nozzles should function properly when
screwed in byhand.
2. Pump. The pressure in themisting system comes from awater pump that is
directly driven by anelectric motor. The pumpcomes pre-filled with oil for
immediate operation. The oil requires an initial change after 50 hours of service,
and additional oil changes every year or 500 hours. Use an ISO 68 gear oil (or
equivalent). When changing the oil disconnect the electricity to the system. Do
not run the pump without oil in the crankcase. Check oil seasonally to make sure
the pump is adequately filled.

Note the anti-drip stopper must not be lost
during disassembly.

Oil change instructions:
Do not attempt to change the oil while the unit is plugged in and always allow the pump and
motor to cool before performing the oil change.
A) Remove the four screws holding on the back cover plate
(See figure 3).
B) Unscrew the plastic fill plug from the top of pump housing (See
figure 4). It is located on the top forward area of the pump housing
when viewed from the back of the unit.
C) Place a catch pan, bottle, or other container suitable for collecting
used oil on the ground below the oil drain valve (See figure 4).
D) Open oil drain valve. Turn the end of the oil drain valve counter-clockwise
and oil will begin to flow out of the drain valve. Removethe drain valve end
cap completely if the oil does not flow or flows slowly. Allow the oil to flow until no more
oil is able to drain from the pump housing.
E) Close the oil drain valve. Make sure it is tightened completely. You willknow that thevalve
is not closed if oil begins to leak when refilling the pump with new oil. Leave your catch pan in
place in case of an accidental spill or leak.
F) Fill the included squeeze bottle with ISO 68 gear oil or equivalent. See the oil capacity below.
(A higher or lower viscosity gear oil may be used depending on the operating environment in
your region.)

G) There are different ways to fill the pump with oil using the squeeze bottle.The two suggested options
are horizontal and vertical bottle orientation. The horizontal method requires you to place the spout of the
squeeze bottle directlyover the top of the oil fill hole and GENTLY squeeze the bottle, allowing a stream of
oil to drop down into the hole (See figure 7).
Figure 7 - Horizontal bottle spout
filling the pump with oil.
For vertical method, turn the bottle upside down and insert the
spout into the fill hole (See figure 8). With the spout in the hole,
firmly squeeze the bottle to force oil into the pump housing. The
vertical method is much quicker, but can be difficult for individuals
with larger hands and can cause someoil to be lost when turning
the bottle upside down. Clean up any spills after the fill process
so that you willbe able to detect any new oilleakage.
3. Filters. The water filter should be checked frequently and replaced if needed. The filter life depends
on the water source and quality of incoming water. If the filter is discolored, dirty, covered in debris,
or damaged replace the filter immediately. To check the filter, remove the back cover screws (See
figure 3) and unscrewthe blue filter housing from the bracket in the rearof the unit. When replacing
the filter, it is also good practiceto clean the housing with avery dilute bleach solution. Use one cupof
bleach mixed with one gallon of water and scrub the inside of the housing using a stiff brush, sponge,
or rag. Make sure the sealing O-ring is in placewhen reattachingthe filter housing,thenfirmly hand
tightenand checkfor leaks.
4. Storage. When storing the system for more than a few days it is important to drain the water.
Draining the water prevents formation of algae. Drain the tank completely by unscrewing the cap
underneath the tank. It may be necessary to tilt the system to drainall the water. Take caution when
tilting the unit because the weight of the fan can cause an unsafe situation if tipped over. Also drain
the filter housing to preserve the filter. Store the unit in a dry location away from areas that are
subject to excessive heat, dust, humidity, freezing, or damage from nearby equipment. If freezing
conditions are likely, you can flush your pump with a 50/50 solution of anti-freeze/water to prevent
severe damage. Also drain any supplyhoses.
For initial operation after along duration of non-use itis 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.
