Transportation and Handling

<Figure 4..>
Hydrobox is delivered on a wooden pallet base with cardboard protection.
Care should be taken when transporting the hydrobox so that the casing is not
damaged by impact. Do not remove the protective packaging until hydrobox has
reached its final location. This will help protect the structure and control panel.
Note:
• The hydrobox should ALWAYS be moved by a minimum of 2 people.
• Do NOT hold piping when moving the hydrobox.

Suitable Location

Before installation the hydrobox should be stored in a frost-free weatherproof
location. Units must NOT be stacked.
• The hydrobox should be installed indoors in a frost free weather proof location.
• The hydrobox should be positioned on a level wall capable of supporting it's
filled weight.
• To find out the weight, refer to "3. Technical Information".
• Care should be taken that minimum distances around and in front of the unit for
service access are observed <Figure 4..3>.
• Secure the hydrobox to prevent it being knocked over accidentally or during
earthquakes.
• The hook and panel supports should be used to fix the hydrobox to the wall.
<Fig. 4..2>
• Install the hydrobox where it is not exposed to water/excessive moisture.

Service access
The hydrobox must be located indoors and in a frost-free environment, for
example in a utility room.

Room Thermostat

If fitting a new room thermostat for this system;
• Position it out of direct sunlight and draughts
• Position it away from internal heat sources
• Position it in a room without a TRV on the radiator/heat emittor
• Position it on an internal wall
Note: Do not position the thermostat excessively close to the wall. The thermostat
may detect the temperature of the wall, which could affect appropriate
control of the room temperature.
• Position it approx. .5 m above floor level

Repositioning hydrobox

If you need to move the hydrobox to a new position FULLY DRAIN it before mov-
ing to avoid damage to the unit.
Note: Do NOT hold piping when moving the hydrobox.
