Filling the hydraulic circuit
WARNING! The water used to fill the hydraulic
circuit must be filtered.
WARNING! Filling the hydraulic circuit must only
be carried out exclusively by a qualified hydraulic
technician.
WARNING! Before carrying out any type of
intervention, disconnect the power supply.
Filling the primary circuit
WARNING! The primary circuits must be equipped
with mechanical filters.
WARNING! Check that all of the shut off valves
are closed.
open the drain valve of the primary circuit and regulate the
pressure switch to 5 bar;
bleed the air from the circuits;
turn on the primary circulation pumps;
clean the circuits leaving the pumps on; check for any loss
from the primary circuits.
Filling the hydraulic circuits of the conditioners
WARNING! Clean the primary circuits before
filling the conditioners.
WARNING! Check that all of the bleeding valves
on the conditioners are closed.
open the shut off valves of the conditioner;
open the bleeding valve (on the upper part of the cooling
coil) and wait for the water to come out.
Maintain a minimum slope of 1% downstream of the
siphon.
once the connections have been made, pour water into
the condensate collection tray of the Jupiter unit and in
the condensate collection tray of the humidifier until both
siphons are full.
Hydraulic connections
For all hydraulic connections (except for the condensate
drain) it is recommended to use the following:
-
flexible hoses to avoid the transmission of vibrations
and to allow the unit to be moved;
-
three piece joints near the connections;
-
shut off valves to isolate the unit from the water circuit:
if possible, use full sphere valves to minimise the
pressure drop.
Check that the chilled water pipe sizes and the circulating
pump characteristics are adequate: an insufficient water
flow affects the performance of the unit.
Check that the water flow directions are respected.
insulate all of the chilled water pipes with closed cell
insulating material (e.g.: Armaflex or equivalent) to avoid
condensation; the insulation must allow accessibility to the
valves and three piece joints.
Check that the hydraulic circuits (both chilled and hot
water) are fed with a maximum water pressure of 6 bar: to
this purpose the installer must install a safety valve in the
hydraulic with a set point of not more than 6 bar.
the minimum and maximum water temperatures inside the
unit (for the chilled water circuit and the post- heating with
hot water) are: 5°C ÷ 90°C.
the maximum amount of ethylene glycol is 50%.
Connect the drainage tube of the unit to the collection tray
(U4) of the humidifier.
Connect the drainage tube of the humidifier (U7) to the
drains of the building using a rubber or plastic tube, which
is resistant to high temperatures (minimum 100 °C) with an
internal diameter of 22 mm.
