Hydraulic connections
1. take away the supplied connection union by acting on
the connection joint.
2. Weld the connection nozzles to the hydraulic line
(supply and return) of the plant.
3. perform the connection between the installation pipe
and the evaporator, using the joint.
NOTE
-
Do not weld on the pipe of the plant with the Victaulic
coupling connected. The rubber seals could be irrevo-
cably damaged.
Operations sequence
Before starting the unit pump:
1. Close all vents.
2. Close all drain taps:
•
Exchangers
•
Pumps
•
collectors
•
storage tanks
3. Flush the system thoroughly with clean water: Use
the bypass to exclude the heat exchanger from the
flow (diagram on the previous page). Fill and drain
the system several times.
4. Apply additives to prevent corrosion, fouling, forma
-
tion of mud and algae.
5. Fill the system do not use the unit pump
6. Conduct a leak test.
7. Isolate the pipes to avoid heat dispersions and forma
-
tion of condensate.
-
Maintenance points such as drains, air vents, etc.
must not be insulated.
NOTE
-
If flushing of the system is neglected, the filter must
be cleaned much more frequently. In the worst
case, the heat exchanger and other components
could be damaged.
