3. Installation
The pump needs to be installed near an electrical and water
connection. Place the pump in a location where water leaks or
accumulation will not cause damage to nearby property or goods.
The purge hose discharges about ½ oz of water when the pump is
stopped, or in between the intermittent modes when the pump stops.
Connect the pump to a water supply with a hose rated for constant
pressure. Standard residential water pressure, generally between 40
and 60 PSI, is sufficient to supply the pump with enough water flow.
Regular garden hose may not be suitable to hold a constant pressure
over time, and can swell up and leak if left under pressure.
HydroMist has hoses available, made specifically for the permanent
connection of the misting pump to a standard garden hose bib.

5.1 First Time Operation
Follow these steps to purge the pump and misting system of air.
1) With your pump plugged in, and the water source turned on, open the ball valve
at the high-pressure misting outlet on the pump. Keep the pump off for now.
2) Remove a misting nozzle at the furthest end of your misting system. This will allow
air to be forced out of the system. If you have a system where the hose splits off into
multiple dead ends, remove a misting nozzle at the end of each leg of your system.
3) Turn on your misting pump to continuously run. Once a constant stream of water
comes out of the ball valve at the high-pressure outlet, close the ball valve.
4) Allow the pump to fill all of the misting lines with water, forcing air out of the
system. Once a continuous stream of water flows out of the end(s) of your misting
system. Turn the pump off.
5) Install all misting nozzles that were removed in step 2.
6) Turn on the misting pump. After a few seconds the system will pressurize.
Depending on the length of hose and size of your misting system, the time to
pressurize may vary slightly.
7) Check your misting system fittings and nozzle for leaks or blockages. Make sure
the pump is turned off before attempting to fix any leaks or blockages.

5.2 Storage
5.2.1 Please follow the steps below to drain water from the pump.
a. Disconnect the watersupply to the pump.
b. Run the pump briefly with the ball valve open to expel any
water from the internal pump cavities. There may be some
intermittent spraying and drainage while the pump purges
water from itself.
c. After water stops coming out of the pump outlet, turn the
pump off.
d. Drain misting lines, pipes, and rings of standing water to
prevent cracking from freezing.
•When the machine is not in use, please keep it indoors.
•If exposed to rain, stop the machine, and immediately remove the plug
to avoid electric shock or leakage.
•Use caution when disassembling high pressure hose, pipe, nozzles,
rings, and fittings. There may be pressure (up to 1000 psi) inside and
serious injury can occur.
•Do not use this machine when temperature is below (0°C/32°F).
Running the pump with ice in the hoses or pump will cause damage to
the pump and can cause an over-pressure situation that may be
dangerous.

The pump is equipped with a thermal overload protection device. This
device behaves like a circuit breaker and protects the pump from damage
due to excess heat or electricity.
There is a reset button to allow the user to reset the device if it activates
to protect the pump.
The cover must be removed in order to access the reset button on the
overload protection device. Once the cover is removed, reset the device
by pressing the button in. Plug the pump in and make sure the device
does not immediately activate again. If the button will not stay in the
normal position (pressedin), check your power supply where the pump is
plugged in. Do not attempt to make anyrepairs while the pump is plugged
into a power source.

The misting pump comes preset at a maximum outlet pressure of 1000 PSI
for a system with 4 misting nozzles. The larger the system, the lower the
total system pressure will be. If the pump produces more than 1000 PSI it
can cause a noisy operating condition. You should decrease the pressure to
a maximum of 1000 PSI by adjusting the pressure regulator on the pump.
The pressure regulator has an adjustment knob located underneath the
pump cover on the brass pump head.
DO NOT attempt to adjust the pump pressure regulator without using a
pressure gauge designed for reading water pressures of at least 1000 PSI.
If you have doubts about your ability to safely and properly install a high-
pressure gauge into the high-pressure side of your misting system, contact
a professional for service.
Operating the pump above 1000 PSI will quickly and significantly decrease
the condition of the internal pump seals. It is outside of the intended use
of this product and related high pressuremisting system parts.

7.2 Procedure for Oil Change
NOTE: The misting pump comes pre-filled with oil.
Oil must be changed after first the 50-hour operation mark,
and after every 250-300 hours of running.
Use ISO 68 oil or equivalent, available from HydroMist:
ISO68 Pump Oil, 21oz. bottle: Part# F02-06-001
Always power off the machine and disconnect power before
performing any maintenance or inspection.
—
Irregular maintenance and failure to change the oil regularly
will cause damage to the machine parts and/or shorten the
service life.
—When changing the oil make sure to remove the old oil
completely. Too much old oil can affect the quality of the new
oil.
—Only change the oil with the pump on a level surface.
—Do not change hot oil. Pump operation increases the oil
temperature to a dangerous level and can cause severe burns.
7.2.1 Purge pressure and water from the misting system by opening the ball
valve on the pump outlet.
7.2.2 Remove the water supply hose and high-pressure misting hose
connections.
7.2.3 Unplug the pump from the power supply.
7.2.4 Remove the pump cover by loosening the eight pump cover screws.
7.2.5 Check inside the bottom of the machine to see if there is any oil leakage
from the pump body. Clean up any oil leaks or spills so that a leak can be
detected.
7.2.6 The maximum oil capacity is 5 oz. (≈145 ml).

Pro Mist 35 User Manual

7.2.7 There is an oil drain plug on the bottom side of the pump. Put a catch pan or
other small container under the plug and unscrew it to start draining the oil.
It is recommended to use an inexpensive plastic bin or other disposable catch
pan that can be discarded after use.
7.2.8 After the oil has drained, reinstall and tighten the drain plug.
7.2.9 Unscrew the oil fill plugon top of the pump housing.

Pro Mist 35 User Manual

7.2.10 Add up to 5 oz. of oil through the fill hole. Use the included oil fill
squeeze bottle or a funnel to prevent spilling oil during the filling process.
7.2.11 Tighten the oil fill plug.Wipe up any spilled oil. Visually check the pump
and motor to ensure all bolts, screws and connectors are tight and in good
condition.
7.2.12 Replace the top cover and tighten the screws to secure the top cover
back into place.
7.2.13 RECYCLE YOUR USED OIL. In many places, it is a crime to dump used oil
into the environment, down the drain, or into the trash (even in a sealed
container). Save your used oil until you can locate a recycling center
and/or bring it to an approved drop-off site where used oil is accepted.
Many auto parts retail stores have drop-off sites where used oil can be
disposed of safely and properly for free.
•Make sure the oil drain plug and oil fill plug are not leaking after an oil
change, and make sure the oil fill plug is securely fastened onto the
pump. Make sure the cover screws are securely tightened after an oil
change.
