FläktGroup LQN(N,P) Air cooler Installation guide

  • Hello! I'm a chat assistant, and I've reviewed the provided installation instruction for the FläktGroup's LQN series air coolers, specifically the LQNN and LQNP models. The document provides guidelines for pipework connections, condensate drainage, and proper installation techniques. I'm here to help with any questions you may have about the installation process or features mentioned.
  • Who should make the pipework connections for the LQNN air cooler?
    Who should carry out pipework connections for the LQNP air cooler?
    What is the recommended depth for the water trap connected to the drain?

CONDENSATE DRAINAGE FOR THE LQN(N, P)
The finned heat exchangers are provided with 32 mm dia. drain con-
nections for connection to a water trap with a depth of at least 100
mm. Preferably use the LQAZ-08 water trap (see separate instruction).
LQNP AIR COOLER
Connections should be carried out by a refrigeration fitter.
The air cooler should be connected to the pipework in such a manner
that expansion forces or the deadweight of the pipework will not be
applied to the liquid connections.
LQNN AIR COOLER
Connections to the pipework should be made by the pipework con-
tractor. Connect the finned heat exchanger to the pipework in such a
manner that expansion forces or the dead weight of the pipework will
not be applied to the liquid connections.
The liquid connections are provided with identification plates for the in-
let and outlet.
CAUTION!
Use a pipe wrench to restrain the pipe connections of
the heat exchanger when tightening the external pipe
connections.
