GENERAL GUIDELINES FOR PLUMBING CONNECTIONS
When you are getting ready to set up the water circuit for the evaporator you should follow the directions
below and in any case make sure you comply with national or local regulations (use the diagrams
included in this manual as your reference).
- Connect the pipes to the chiller using flexible couplings to prevent the transmission of vibrations and to
compensate for thermal expansions. These units are all configured for installation of the water inlet-
outlet pipes outside the unit (on the rear) and these pipes are supplied as a standard accessory at no
extra cost for the customer.
-
It is recommended to install the following components on the pipes:
pair of quick connect couplings with pipe section to be welded (optional that may be selected from
the price list). They facilitate the operations of connecting to the plumbing system, greatly speeding
up installation.
temperature and pressure indicators for routine maintenance and monitoring of the unit. Checking
the pressure on the water side will enable you to verify whether the expansion tank is working
efficiently and to promptly detect any water leaks within the equipment.
traps on incoming and outgoing pipes for temperature measurements, which can provide a direct
reading of the operating temperatures. Temperature readings can in any case be obtained from the
microprocessor installed on the unit.
regulating valves (gate valves) for isolating the unit from the water circuit.
metal mesh filter (incoming pipes), with a mesh not to exceed 1 mm, to protect the exchanger from
scale or impurities present in the pipes.
air vent valves, to be placed at the highest points of the water circuit for the purpose of bleeding air.
[The internal pipes of the unit are fitted with small air vent valves for bleeding the unit itself:
this
operation may only be carried out when the unit is disconnected from the power supply -
make sure that the circuit is completely full of water, then carefully bleed out the air and check again
to make sure no air is present before starting the pump for the first time.
