Filling the hydraulic circuit
WARNING! The water used to ll the hydraulic
circuit must be ltered.
WARNING! Filling the hydraulic circuit must only
be carried out exclusively by a qualied 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 lters.
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
lling 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 humidier until both
siphons are full.
Hydraulic connections
For all hydraulic connections (except for the condensate
drain) it is recommended to use the following:
- exible 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 insufcient water
ow affects the performance of the unit.
Check that the water ow directions are respected.
Insulate all of the chilled water pipes with closed cell
insulating material (e.g.: Armaex 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 humidier.
Connect the drainage tube of the humidier (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.
