(8) If you need to connect the hydro box with floor heating system or water tank, please
install waterline solenoid valve C and solenoid valve D according to units installation
diagram. The solenoid valves are used to control the heating of water tank and floor
waterline. Valve C and valve D should be straight-through electromagnetic water valve of
small resistance (Valve C and valve D are supplied for hydro box NRQD16G/A-S). Valve
C, valve D and floor heating actuator should all be normally closed.
(9) When floor heating is connected, its water system is different from the water system of
water tank. Therefore, tap water filling port and drain port should be connected during the
engineering setting.
(10) User can require project engineer to add back water pump based on actual needs. This
can maintain users water pipe temperature and avoid waste.
(11) Water pipeline can only be installed after hydro box is installed securely.When installing
the connection pipes, please prevent dust or other foreign matters from getting in the
pipeline.
(12) After the entire pipeline is connected, check if there is any leak. After ensuring that there
is no leak, apply insulation treatment to the pipeline. Please pay special care to the
insulation treatment of valves, pipe joints, and other joints. We suggest you use
insulating cotton that is thicker than 15mm.
(13) The temperature keeping and pressure bearing water tank depends on tap water
pressure to supply hot water. Only when there is tap water will hot water be available.
When user wants to use hot water, please keep the cut-off valve of water tank cold water
inlet in open status.
(14) Cooling and floor heating cannot be started at the same time. If floor heating cannot start
working and Mode conflict is displayed, please turn indoor unit into heat mode or turn it
off in heat mode.
(15) The horizontal distance between hydro box and water tank should not exceed 5 meters
and the vertical distance between them should not exceed 3 meters. If the distance
exceeds above limits, please contact our company. Recommended installation method is
to keep the water tank at lower side and the hydro box at upper side.
(16) Please prepare installation materials according to above dimensions and specifications.
If cut-off valve is installed outdoors, its better to use PPR pipe fittings to avoid the valve
from being frozen under low temperature.
