3.2 Preliminary operations

3.2.1 Opening cable knockouts

There is a pre-cut part that can be removed for running wires.
Do not remove the unit front panel for easier drilling of the knockouts.

The pre-cut section of the sheet can be removed by punching the 3 con-
nection points along the line first using a screwdriver and finally with
your hands. When the cable knockout is open, remove the burrs and fit
the cable protective bush supplied with the unit for cable protection.

3.2.1 How to remove the front panel

1. Remove screws of the front panel.
2. Pull the front panel downward with the handle.

3.2.1 Drain hose and base pan knockouts

In case of draining through the drain hose, attach the drain nipple (

)

and use the drain hose (Inner diam.: 16 mm) sold on the market. When
there is a possibility of freezing of drain at the cold district or a snowfall
area, be careful for drainage ability of drain.

The drainage ability increases when knockout holes on the base pan are

opened. (Open the knockout hole to outside using a hammer (

), etc.).

Before installation, check strength and horizontality of the base so that

abnormal sound does not generate.

According to the dimensions and clearances, fix the base firmly with the

anchor bolts (Anchor bolt, nut: M10 x 2 pairs).

If the unit is installed in a very windy place, protect the fan with a wind

protection screen and check that it works correctly.

3.3 Water connections

The 30AWH__H units are equipped with an integrated hydronic module
that allows fast installation with the aid of a few external components.
The 30AWH__X and 30AWH__NX units, on the other hand, do not have
a circulation pump and expansion vessel. For this reason, they must be

provided outside. In any case, all the necessary protections and valves
are to be inserted in the water circuit inside the unit. Refer to the figure
below for the exact connection of the water pipes.

3.3.2 Water connections

Note: The correct dimensioning of the expansion vessel is left to the
installer as a function of the type of plant.
The discharge of the safety valve can be channelled to the outside of the
machine using the pre-cut holes. In this case, it is necessary to provide a
open drain funnel.

Installation

Make the plate heat exchanger hydraulic connections with the
necessary components, using material which will guarantee that the
screwed joints are leakproof.
The typical hydraulic circuit diagrams (par. 3.3.3) show a typical water
circuit installation.
For an application with a water circuit, the following recommendations
must be taken into account:

The pump must be fitted immediately before of the heat exchanger

and after the connection to the system return (unit without hydronic
module).

*UJTBEWJTBCMFUPJOTUBMMTIVUPòWBMWFTUPBMMPXJTPMBUJPOPGUIF

most important circuit components, as well as the heat exchanger
itself. These valves (ball, globe or butterfly valves) should produce a
minimum loss of charge when they are open.
Provide unit and system drains and vents at the lowest system point.

Install purges in the higher sections of the installation.

Pressure ports and pressure gauges should be installed upstream

and downstream of the water pump.
All piping must be adequately insulated and supported.

ATTENTION:

The presence of particles in the water can lead to obstructions in the

heat exchanger. It is therefore necessary to protect the heat
exchanger inlet with an extractable mesh filter. The filter mesh gauge
must be at least 10 mesh/cm^2.
After assembling the system, or repairing the circuit, the whole

system must be thoroughly cleaned with special attention paid to
the state of the filters.
Pump flow rate control is made through a flow control valve, which

must be installed on the delivery pipe during installation.
When water has to reach temperatures below 5°C, or the equipment

is installed in areas subject to temperatures below 0°C, it is necessary
to mix water with inhibited ethylene glycol in suitable quantity.
