following information:
When you complete installation of the unit and have
performed all the necessary settings, ensure that all
the metal plates are closed. This can protect your
from electrical parts and high-temperature parts
inside the unit.
The electric control box cover plate can only be
opened by an electrician who is certified for
maintenance.
Discharge air in the system.
9 DOMESTIC HOT WATER TANK
A domestic hot water tank(with or without booster heater)
can be connected to the unit.
The requirement of the tank is different for different unit
and material of heat exchanger.
Temperature
probe(Ttank)
Coil
Outlet
Inlet
If the tank volume is greater than 240L, the temperature
probe (Ttank) should be installed at a position higher
than half of the tank’s height.
If the tank volume is less than 240L, the temperature
probe should be installed at a position higher than 2/3 of
the tank’s height.
If the booster is installed, the booster heater should be
installed below the temperature probe.
The heat exchanger (coil) should be installed below the
temperature probe.
The pipe length between the hydro module and tank
should be less than 5 meters.
