CONNECTION OF THERMODYNAMIC GROUP AND STORAGE WATER HEATER
After securing the thermodynamic group to the storage water heater with its bolts, we can proceed with
making the refrigeration couplings between the group and the storage water heater.
Procedure for making the refrigeration couplings:
a)
Remove the protection caps from the “one-shot” valves on the pipes of the condenser and
thermodynamic group.
b)
Tighten the valves with your hand making a few turns
c)
Tighten with a suitable wrench, applying a torque in conformity with the diameter of the pipe
employed (according to table in point 4.4.1. Insufficient torque will cause leaks of cooling fluid.
Excessive torque on the coupling will damage the edge of the pipe and cause leaks.
