Transport of semicompact units

Semicompact units consist of two or three blocks that form the unit once they are connected together.
Blocks of semicompact unit
Lift the blocks of semicompact units one after another.
Tie up individual blocks from underneath before lifting them.

Safety rules

●
The equipment in the outdoor version (marked by letter N in the name) can be installed into
outdoor environment - environmental temperature must be between -25°C and +55°C, relative
humidity is not limited (except for conditions in the Chapter 2.2, bullet point 2). The equipment
must be sufficiently thermally protected from the effect of low temperatures (e.g. by using anti-
freeze liquid in the water heater circuit, etc.)
●
The unit must have continuous warm water supply during the heating season.
●
Protection of the unit's internal components from getting cold when the unit is not working is
provided by a shut-off damper in EHA ducting (on the outlet discharge side).
●
The appliance may be operated within the temperature range of ventilation air between -25°C and
+40°C with relative exhaust air humidity up to 80%, in an environment where there is no risk of fire
or an explosion of flammable gases and fumes, and air transported must not contain organic
solvents or aggressive substances that might damage mechanical parts of the unit. If there is a
danger of such gases and fumes temporarily entering the duct system (e.g. during floor bonding,
painting), the unit must be switched off sufficiently in advance.
●
Be careful during the installation not to damage the unit casing (e.g. by hanging it only on two
lugs).
●
After placing the equipment make sure its position is stable and secure the equipment against
possible movement.
●
Follow all work safety rules during the manipulation and installation work (including safety rules for
work in heights and lifting weights), use proper tools and protective clothing.
●
Only a qualified person may operate the lifting equipment and binding tools.
●
Use ropes being at least 5m long to transport the unit on a crane. In no case it is allowed to use
shorter ropes, there is a risk of deforming the unit (see label on the unit)!
In case of manipulation with any detachable parts (e.g. roof of the unit) it is necessary to fasten
these parts to the casing of the unit at the designated point.
Appliances with hot water heaters
●
Must be permanently connected to power supply to provide for the anti-freeze protection of the hot
water heater. In case of a prolonged power outage the heating medium must be drained from the
hot water heater including the control set. We recommend draining water from the heater with
pressurized air, not using a gravity flow!
The bars must be wider than the
unit itself.
