Installation

Pump Installation Instructions

1. Place the Roof cooler pump in its preferred location. Placing it on the roof near the system is preferable. If it cannot be placed on the roof, it is best to locate it as close to the input location of the roof cooling lines.
2. Pump must be level.
3. Water should be supplied to the pump inlet (black) a using 1-inch minimum source hose/pipe. Using smaller than a 1-inch supply can restrict the pump’s needed flow and damage the unit.
4. Plug in the power cord to dedicated 20-amp 120 Volt receptacle. (Use GFCI)
5. Priming is not necessary when a pressurized supply is available.
6. Do not run the pump dry.

Output Installation Instructions

1. Attach 1-inch PVC plumbing to output (white) of the pump.
2. 1-inch piping is required between the pump and the output lines.
3. Install the drain valve at the lowest point of the line as discussed in the design consultation for your system.
4. Use the 1-inch to ¾-inch reducer (supplied) to transition from the 1-inch line to the output lines.
5. Run the ¾-inch roof misting line parallel according to the design discussed in the planning stages of your system. Standard layout has lines spaced every 10 feet
6. For proper roof coverage, stagger the location of Roof misters at 5-foot intervals in relation to the parallel line. Each line should have roof misters spaced every 10 feet. (see picture below for an example).
7. Secure roof misting lines with the magnetic clamps (provided).
8. Ensure that adequate time is allowed for any PVC glues to dry before turning on the system.

Maintenance

Winterization: 

• To help maintain the integrity of the system and to prevent unnecessary damage, it is important to winterize the pump and other components of the misting system BEFORE temperatures drop below freezing. As water becomes Ice, it needs more room to expand. Even one night of freezing temperatures can damage the pump, lines, fittings, and/or nozzles.  Any damage to system or components due to freeze is not covered under warranty.

To winterize

• Unplug the pump.
• Remove access cover.
• Drain all water from pump by unscrewing the drain plug from the base of the pump.

• Open the solenoid valve manually.

• Wind up power cord.
• Store pump, drain plugs, and any other loose parts in a secure location.
• To avoid condensation/corrosion problems, do NOT cover or wrap pump with plastic film or bags.
• Open drain valve on the 1-inch supply line between the pump and the misting lines.
• Open drain valve(s) on the end of misting lines(s)
• Allow water to full drain from system.

De-Winterization:

• Close the solenoid valve back into the “Auto” position (see above).
• Follow Installation steps to flush/purge lines before operation.
• If pump fails to start after shutdown period: Disconnect all power before servicing. Insert a 1/4” hex key into the center hole of the fan guard and rotate motor shaft to free seal. Completely remove the hex key before reconnect power source.

Protect from Heat:

• Keep the unit in a well ventilated location to prevent overheating. 
• Provide ample cross ventilation. 

Protect against Dirt: 

• Protect from any foreign matter or splashing water.
• Do not store (or spill) chemicals near the unit
• Avoid sweeping or stirring up dust near the motor while it is operating.
• Damages resulting from a failure to protect this unit may void the warranty.

Protect against Moisture: 

• This unit comes in a weather resistant enclosure to protect it from rain. However, the unit cannot be submerged in water.
• It may still be advisable to cover the unit(s) in the event of extreme or catastrophic weather, eg. hurricanes, tornadoes, blizzards, etc.
• Do not allow the pump to operate if it has been flooded.
• Flood damage may void the  warranty.

NOTE: DO NOT wrap the unit with plastic or other air tight materials. The unit may be covered during a storm, for winter storage, etc., but NEVER when operating or expecting operation.
