MODULAR UNIT SYSTEM (WITH EXTERNAL PUMP)
Notes:
1. Parts in the dotted box are optional components, and if the site does not need installation, the pipeline here can be directly
connected.
2. In modular connection, considering the balance of water pressure drop and water flow rate, the same route design should
be applied. If pipelines could not be installed in the same route due to the limitation of installation space, please contact the
local JCI office for confirmation.
3. In modular connection system with external water pump, the standby water pump is not necessary; but the standby water
pump is recommended to be included in case that the water pump in common use might break down and affect the normal
use of the unit.
