Stage 3 – Water Supply Installation
Illustration 7 - Water Supply Installation
Note: Do not over tighten hose fittings as this may damage the seals.
Install an isolation valve (not supplied) on the water line near the evaporative module's inlet for easy
maintenance and servicing. We recommend fitting a pressure gauge for commissioning and
maintenance.
Flush the water line thoroughly before connecting the feed water pipe-work to the evaporation
module.
Follow the water supply specifications as mentioned below:
o
Water Supply Size - Ø3/4’’(20mm), garden hose
o
Maximum Water Supply Pressure - 70psi (4.8bar)
o
Maximum Water Supply Temperature - 68°F (20°C)
Connect the humidifier to a clean drinking water supply.
o
The humidifier is capable of operating with a wide range of water qualities such as reverse
osmosis (RO), or tap water. If the humidifier is connected to hard water, it will result in scale
build-up on the evaporative module and will require frequent cleaning and replacement.
o
If the supplied water is treated with reverse osmosis or de-ionization filtration, control the total
dissolved solid contents in the water, otherwise water acts as a solvent agent resulting in
rapid evaporation and media degradation.
o
Water conductivity of the water should be between 100 and 550 microS/cm at 68°F (20°C).
o
For direct feed, water conductivity should not be lower than 150 microS/cm at 68°F (20°C). If
it is lower, mix the treated water with tap water to achieve the recommended conductivity.
Alternatively, install SKV with recirculation (SKVR) and setup the dilution cycle accordingly.
