Air-handling units

Table of Contents

The s-AIRME-G02/G07 units require hydraulic connections to the condensate drains and to the inlets and outlets of the pre

and post-heating coils available as accessories.

The inlet and outlet are marked with these labels affixed directly on the machine.

INFORMATION:

Install an expansion vessel with a safety valve in the hydraulic circuit. The hydraulic circuit must be sized

according to the applicable laws in force.

Below are recommendations on design of the hydraulic connection to the coils:

During the design phase, envisage the installation of the following components on the inlet water line:

AV - Anti-vibration: to isolate the vibrations that can be transmitted from the system.

M - Pressure gauge (with stopcock): indicates the water pressure in the inlet line.

T - Thermometer: indicates the water temperature in the inlet line.

SA - Air vent: to eliminate air in the inlet line.

SC - Drain valve: to drain water out of the system. To be used also for connecting an external pump for chemical

washing.

MF - Mains filter: (with a system of RU valves for cleaning the filter): for trapping impurities in the system.

Assemble the following components on the water outlet line:

RUa - Shut-off valves: for shutting off the supply of water to the machine during maintenance.

AV - Anti-vibration: to isolate the vibrations that can be transmitted from the system.

M - Pressure gauge (with stopcock): indicates the water pressure in the inlet line.

T - Thermometer: indicates the water temperature in the outlet line.

SA - Air vent: to eliminate air in the outlet line.

SC - Drain valve: to drain water out of the system. To be used also for connecting an external pump for chemical

washing.

Install an expansion vessel with a safety valve in the hydraulic circuit. The hydraulic circuit must be sized according to the

applicable laws in force.

WARNING:

Maximum operating pressure 10 BAR, including the hydrostatic head – PN10.

The connection pipes must be suitably supported so that they do not weigh down on the machine.

Avoid rigid connections between the machine and the pipes, and install vibration dampers.
