18.  HYDRAULIC CONNECTIONS

HYDRAULIC CONNECTIONS

The units may be available with or without integrated hydronic kit, in any 

case:

ATTENTION The choice and installation of components external to the 

unit is up to the installer, who must operate according to the rules of 

good technical design and in compliance with the regulations in force 

in the country of destination.

ATTENTION The hydraulic connection pipes to the unit must be suitably 

dimensioned for the effective water flow rate requested by the system 

when running. The water flow rate to the heat exchanger must always 

be constant

ATTENTION Wash the system thoroughly before connecting the unit. 

This cleaning will eliminate any residues such as welding drips, scale, 

rust, or other impurities from the piping. These substances can also 

deposit inside and cause unit malfunctions.  The connection piping 

must be adequately supported so that its weight does not rest on the 

appliance 

CONNECTIONS

Before starting the system, check that the hydraulic circuits are connected 

to the current exchangers (or, that the evaporator in the air/water units 

or evaporator and condenser in the water water units or the intake and 

flow fittings have not been reversed). The water circulation pump must 

preferably be installed upstream so that the evaporator/condenser is 

subject to a positive pressure. The water inlet and outlet connections are 

indicated in the dimension tables in this manual, or available on www.

aermec.com

It is important to follow the recommendations (not complete) below:

•   The water pipes must not transmit radial or axial forces or vibrations 

to the exchangers (use flexible hoses to reduce the transmitted 

vibrations)

•   It is necessary to install manual or automatic vent valves in the 

highest points of the circuit; and also provide discharge fittings in the 

lowest points to allow emptying the entire circuit

•   To maintain the pressure in the circuits, you must install an expansion 

tank and a safety valve

•   Respect the water inlet and outlet connections shown on the unit

•  Install manometer

 

on the water inlet and outlet fittings.

•   Install stop valve near the water inlet and outlet fittings.

•   After performing a leak test, insulate the pipes to reduce heat loss 

and prevent the formation of condensation

•   If the external water pipes are in an area where it is likely that the 

environment temperature drops below 32°F, insulate the pipes and 

provide an electric heater. As an option, you can also protect the 

pipes inside the unit.

•   Check the continuity of the earthing.

ATTENTION You must install the water filter supplied, in the hydraulic 

circuit upstream of the heat exchanger. FAILURE TO DO THIS 

INVALIDATES THE WARRANTY.

ATTENTION The charge or discharge of the heat exchange fluids must 

be made during installation by qualified technicians using the fittings 

provided on the hydraulic circuit. Never use the unit heat exchangers to 

top-up the heat exchanger fluid.

DISCHARGING SYSTEM

In the event the system is stopped during winter, the water in the heat 

exchanger can freeze damaging the heat exchanger irreversibly. To 

prevent danger of freezing, three solutions are possible:

1.   Full water discharge from the unit.

2.   Using the resistances. In this case the resistances must always be 

supplied with electrical power for the entire period of possible 

freezing (machine in stand-by).

3.   Operation with glycol/water fluid, with a percentage of glycol based 

on the minimum outdoor temperature expected.

ANTI-FREEZE PROTECTION

ATTENTION: the addition of glycol is the only effective protection 

against freezing; the glycol/water solution must be sufficiently 

concentrated to ensure proper protection and prevent ice forming 

at minimum temperature provided for a given installation. Take the 

necessary precautions if using non-passivated anti-freeze solutions 

(monoethylene glycol or monopropylene glycol). Corrosion phenomena 

may occur with these anti-freeze solutions in contact with oxygen.

However, always refer to the glycol supplier documentation to check its 

recommended concentration.

Do not fill up the hydraulic system by glycol near the suction of 

the pump. High concentration of glycol could stuck the pump. 

Do not use the pump to mix water and glycol
