4. As shown below, a manual flow rate adjustment valve is installed on the sprinkler inlet of each module.
Adjust the flow rate so that the amount of water sprinkled on each module is almost uniform. If sufficient
water pressure cannot be obtained, install a pressure pump (procured locally).

5. If the water pressure is too high, provide a pressure reducing valve (provided locally) and a safety relief valve
(provided locally), and the adjust the water pressure.
6. If water hammer causes vibration or water leakage, install a water hammer arrester (provided locally) as
close to the sprinkler as possible.
7. Also, if water sprinkled on the air heat exchanger surface is not uniform, the spray nozzle may be clogged
with foreign matter. The spray nozzle of the sprinkler is shown in the figure below. Since the spray nozzle can
be easily removed with a tool such as a spanner, wash it or replace the spray nozzle.
Note: Spray nozzle A and spray nozzle B are different types of nozzles. Pay attention to their difference when
installing.

8. Water from the sprinkler may be scattered around. Therefore, if necessary, apply waterproof treatment to the
base surface, and provide drain channels and drain ports around the product so that drained water does not
accumulate on the base surface.
