13.2. RECOMMENDATIONS FOR HYDRAULIC CONNECTIONS
1. It is recommended that all units are connected to a water supply and return pipe system of
the Tickelman Loop type. The Tickelman Loop system is self-balancing and thus only requires
manual balancing if a large number of units with different ow and pressure loss characteristics
are connected to a single hydraulic loop. A very simple way of checking the hydraulic balance
is to measure the temperature difference between the water connections. To ensure a correct
water ow, the difference must be in the region of 3 to 7 °C in Cooling mode and 2 to 5°C in
Heating mode.
A system with two parallel pipes can also operate in a perfectly adequate manner, but it is more
difcult to achieve, and to maintain, balance.
2. Never connect a unit to the water supply and return lines without completely cleaning
and flushing out the hydraulic loop beforehand. After performing these operations, the
units must be connected, with all valves completely open, ready for the system to be lled with
water.
3. Water exchanger clogging reduces efcient appliance operation. We recommend the installation
of a strainer lter (Ø 0.8mm) on the appliance's water inlet pipe. The lter must be installed if
the water circuit cannot be cleaned. This lter should be installed between two cut-off valves
and it must remain easily accessible for the user so that it can be checked at regular intervals.
4. Steel, copper or P.V.C. pressure pipes may be used.
5. It is advisable to make the unit’s water supply and return conveyance lines with short lengths
of high-pressure hose, as they form excellent shock absorbers for unit operating noise and
hydraulic pressure surges.
One of the hose ends must be tted with a rotating connector to facilitate removal for
maintenance. Rigid pipes can be connected directly to the unit, but this is not recommended
due to their inability to absorb vibrations and noise.
Rigid pipes must be equipped with removable connectors to facilitate future removal of the unit
from its location.
