Condensate Drainage Connection; Leak Testing - REMKO KWK Series Operating And Installation Instructions

6.2 Condensate drainage
connection
If the temperature falls below the dew point, con-
densate will form on the cooling fins during cooling
mode. Below the heat exchanger is a collection
tray which must be connected to a drain.
The condensate drainage line should have an
n
incline of min. 2%. This is the responsibility of
the customer. If necessary, fit vapour-diffusion-
proof insulation.
n Route the unit's condensate drainage line
freely into the drain line. If the condensate runs
directly into a sewer pipe, fit a trap to prevent
any unpleasant odours.
n When operating the unit at outside tempera-
tures below 0 °C, ensure the condensate
drainage line is laid to protect it against frost. If
necessary, fit a pipe heater.
n Following installation, check that the conden-
sate run off is unobstructed and ensure that the
line is durably leak tight.
NOTICE!
The condensate drainage connection of the
condensate tray which is not used must be per-
manently sealed (a cap or similar).

6.3 Leak testing

The leak test is carried out after the connection
has been made.
1. Flush the system twice with tap water.
2. Clean the sieve insert on the dirt trap.
3. Fill the system with water again and bleed
the unit at the manual bleed valves.

4. Adjust the test pressure to at least 200 kPa
(2.0 bar).
5. Check the connections after a period of at
least 24 hours for leaking water. If leaks are
visible, the connection has not been properly
made. Tighten the connection or establish a
new connection.
6. After a successful leak test, remove the
excess pressure from the medium piping if a
water-glycol mixture is used or adjust the
non-circulating pressure to the required
system pressure.
