Blue Box - 30
The water inlet and outlet must be connected in the positions indicated
as labelled on the unit.
4.5 CONDENSER WATER PIPE CONNECTIONS
All units are provided with stainless steel threaded hydraulic connections. Sizes and locations are indicated in the
dimensional data at the end of this manual.
For units equipped with more than one compressor, water inlets and outlets must be manifolded together.
For connection locations and dimensions see the dimensional drawings at the end of this manual.
4.5.1 Pressostatic valve
When using city water, rather than a cooling tower, it is recommended that a pressostatic valve is installed to
ensure the correct operation of the unit.
The pressostatic valve is also recommended for closed circuit installations. This valve guarantees regular operation
of the unit with changing condenser water conditions (for example when restarting after a weekend pause). The
pressostatic valve is absolutely necessary if the tower water entering into the condenser can decrease below 20
°C (see figure 5). The pressostatic valve must provide a condensing pressure higher than 12.5 bar relative.
Consult Blue Box for further information.
All units are equipped with plate heat exchangers. It is compulsory to
install a metallic filter, on the water inlet piping, with a mesh not larger
than 1 mm. If a filter is not installed the warranty will be terminated
immediately.
Caution: When making hydraulic connections never use naked flames
close to or inside the unit.
We strongly recommend installing a pressure relief valve on the hydraulic
circuit. In the event of serious system breakdown or emergency (e.g.
fire), the relief valve will make it possible to depressurise the system
thus forestalling possible pipe bursts. Always connect the relief valve
outlet to a pipe of diameter no smaller than the valve opening, and route
it to a location in which persons are protected from the jet of expelled
water.
