Condensate Drain - Carrier 50EN 415 Installation, Operation And Maintenance Instructions

10 - CONDENSATE DRAIN

All models are equipped with a condensate drain pan in the
indoor circuit, with a bronze, gas threaded 1 1/4" M drain junction.
Outdoor circuit
pans (optional)
With outdoor temperatures which are lower than 0ºC
the necessary precautions must be taken to prevent the
water in the drain ducts from freezing.
In units where the outdoor condensates pan is optional, the
outdoor circuit drain (junction 1" M) is independent from the
indoor circuit drain. Do not connect both drains.
Some options have their own pan with independent drain
junction, gas threaded:
● Cooling recovery circuit: 3/4" M in bronze.
● Rotary heat exchanger: 1" M in bronze.
● Gas burner: consult in the specifi c instruction brochure of
burners Nb 09.100 (supplied with the burner).

Siphon installation norms
● Check that the condensate outlet is not clogged.
● Perform the assembly as per the scheme of the attached
starting diagram:
● Pan in overpressure:
It is installed to avoid the access through the drain piping of
bad smells.
● Pan in underpressure:
Besides the previous application, water must be sucked from
the pan:
- For the correct siphon design, the "A" height must be at
least twice that of the underpressure (mm.w.c) where the
condensate pan is placed.
- The drain piping must be slightly sloped to ease circulation
towards the drain.
- The original diameter of the piping must be respected. No
reduction can be made.
