Figure 4 Recommended Condensate Trap Dimensions - Data Aire DAPA-2.5 Installation, Operation & Maintenance Manual

Notes:
1. This trap is capable of handling static pressures equal to 4" H
available for ceiling units. If the unit fans are standard, there is no need to consider different
dimensions but if higher total static pressure is expected, more vertical drop is required.
2. Some applications have no convenient means of allowing a gravity drain. In this case, a
condensate pump can be used. These come either factory mounted or shipped loose.
3. Factory mounted condensate pumps do not require a separate power source.
4. Condensate pumps that ship loose or are field provided, typically require a dedicated 110-volt
power source.
5. Field pipe connections must be made to the pump discharge connection.
6. A check valve must be installed to prevent short cycling. Pumps must be located below the
condensate drain pan level.
