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).

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.

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-
