Rinnai RDT-62-RM-W Operating Instructions Manual page 9

Discharge of Humidity
• Do not directly connect the discharge tube to a ventilator, etc.
Insufficient air flow from the ventilator might block air discharge and stop the equipment to stop,
and cause humidity to leak or mold to form.
• For optimal function of the machine, the length of dia. 80 mm humidity duct is
recommended not to exceed 6 m and 1 bend. Reduce 2 m when adding one bend.
• Maximum allowable length is 11 m and 1 bend (equivalent to 5 m and 4 bends)
for dia. 80 mm humidity duct. Reduce 2 m when adding one bend. Under this
condition, the machine still functions safely and normally, however, the drying
time and the frequency of lint filter cleaning may increase.
• According to the real situation, in case it is not necessary to install the humidity
duct, please use the exhaust humidity top to install at exhaust hum.
