1. Drainage pipe selection
➢
The drainage pipe diameter shall not small than the drain hose of indoor unit
➢
According to the water flow rate and drainage pipe slope to choose the suitable pipe, the
water flow rate is decided by the capacity of indoor unit.
Relationship between water flow rate and capacity of indoor unit
Capacity (x1000Btu) Water flow rate
(l/h)

According to the above table to calculate the total water flow rate for the confluence
pipe selection.
For horizontal drainage pipe (The following table is for reference)

2. Install the drain hose with downward gradient (1/50 to 1/100) and no risers or traps are used
for the hose
.
Be sure there is no crack or leak on the drain hose to avoid the formation of air pocket
( Figure )
3. Supporter gap of drainage pipe
