Installing Condensate Drain Lines - LG R5TT20F-SA1 Engineering Product Data Book

Heat Pump Water Heater
14. Installation
* The water may drip from the discharge pipe
of the pressure-relief device and that this pipe
must be left open to the atmosphere.
* The pressure-relief device is to be operated
regularly to remove lime deposits and to
verify that it is not blocked.
* A discharge pipe connected to the pressure-
relief device is to be installed in a
continuously downward direction and in a
frost-free environment.
Installing Condensate
Drain Lines
NOTE
• When making drain fitting connections to the
drain tubing, DO NOT overtighten.
Overtightening fittings could crack or damage
the condensate drain pan.
• Condensate from this unit is not acidic.
The condensate drain lines and connections to
the drain piping must meet state and local
codes.
Do not reduce the drain line size to less than the
condensate connection size provided.
Ensure that the condensate drain lines maintain
a downward slope for proper drainage.
The drain line should be insulated to prevent
condensation from forming on the outside of the
drain line.
If no floor drain is available or the drain is above
the level of the condensate line, then a common
condensate pump with a capacity no less than
7.5 liters per day must be installed.

1
Apply Teflon tape on the G end to prevent
leaking.
2
Attach elbow with 3/4" slip &3/4"G to the
primary drain connection.
3
Using an approved sealant, insert the PVC
pipe into the female end. Condensate drain
must be piped to an adequate drain.
4
Using 1/2" PVC piping, a elbow with 1/2"
slip & 1/2" G, and an approved sealant,
attach the elbow to secondary drain
connection and insert the PVC pipe into the
female end.
