3. INSTALLATION
3.1.Hydraulic installation
The water pump group must always be installed where the pump motor shaft is in the horizontal position.
Before installing the system should be flushed out thoroughly to clear all foreign matter such as solder,
steel wool, copper filings.
The pump group must be connected to the installation with thermomanomeher from the water heater side
and valves from the net side, like in the below example.
Connection to the exchanger and installation should be carried out so as not to allow for stresses which
may result in mechanical damages or leakage. The pipeline should be supported in some place to avoid the
pass of weight and thermal stresses onto the exchanger's connections.
Ends of the groups are ended with
an internal thread. To provide the seal, connection should be made with
using teflon tape or other sealing material.
During assembly of the system to the pump groups, counter the
connection with additional wrench.
Fig.4. Example of installation
The pipe lines and place of water pump group should be planned so as it does not collide with the other
AHU sections and make possible inspection them without necessity disassembly.
Applied method of pump group installation with the supply system should allow for an easy pipeline
disassemble in order to remove the exchanger from the AHU.
Below drawing shows the available positions.
