M&C EC Series Instruction Manual page 16

Note
Ensure that the connections are sealed adequately by noting the following:
Borosilicate glass heat exchangers with connections GL18-6 respectively GL25-12 (standard)
•
Before assembly, check the GL coupling rings to see if the PTFE/silicon locking rings have been damaged.
•
The sealing rings should be installed with the PTFE side facing the medium.
PVDF- resp. stainless steel heat exchangers with G1/4" i resp. G3/8" i
•
The correspondingly dimensioned tube respectively tube couplings with threaded connections have to be
screwed in with PTFE thread sealing tape.
To grant a functional and unproblematic mounting we recommend using union pieces with taper pipe
•
thread type R according to DIN 2999/1 in connection with suitable sealing tape.
Note
Option: stainless steel heat exchanger with NPT
•
The heat exchangers with NPT threaded connectors are marked with circulated notches.
•
In order to ensure the tightness of the connections, the NPT thread must be screwed in with sealant or
fixed with adhesive.
In the standard configuration, the tubes for removal of condensate are connected directly to the heat exchangers.
These protrude with the GL25-12 tube connectors (standard, Borosilicate glass heat exchanger) respectively with
G3/8" (standard) thread joint PVDF or stainless steel heat exchanger above the base plate of the cooler housing
(figure 5).
Condensate removal is done by customer according to the type of operation with:
•
peristaltic pump(s) type SR25.2 implemented optionally in the cooler housing,
•
external mounted condensate vessel(s) with manually emptying respectively,
automatic float-type condensate traps type AD (only for over-pressure operation).
•
Note
16
Do not mix up the hose connections; the inlet and outlet connections of the heat
exchangers are marked with arrows;
Ensure that the connections are sealed adequately;
To ensure free removal of the condensate, ensure that the listed diameters for the
condensate removal lines are not reduced!
When fixing the connectors in the PVDF respectively stainless steel heat exchanger hold
up with a wrench at the pane of the bolt head!
When using the stainless steel heat exchanger with G3/8" condensate connection, the
automatic condensate trap AD-SS can be mounted directly using a threaded adapter, part
no. FF11000 (1/2" NPT to G3/8" i). This eliminates the otherwise necessary wall mounting
and piping or tubing of the trap.
