1 Safety instructions

■ Always obey the safety regulations,

warnings, comments and instructions

given in this document. When

the safety regulations, warnings,

comments and instructions in this

document are not obeyed personal

injury or damage to the unit can

occur;

■ Always obey the general and locally

applicable construction, safety and

installation instructions of the local

council, electricity and water boards

or other agencies;

■ Always connect air ducts of at least

900mm to the unit before you connect

the power to the unit. This ensures the

motor cannot be touched while the

unit is active;

■ After installation all parts that can

cause personal injury are secured

behind the casing. Tools are required

to open the casing;

■ The installation, commissioning and

maintenance must be carried out by

a certified engineer unless instructed

differently. A non-certified engineer

can cause personal injury or damage

the performance of the ventilation

system;

■ Do not modify the unit or the

specifications given in this document.

A modification can cause personal

injury or damage the performance of

the ventilation system;

■ Always disconnect all poles of the

power supply of the unit and optional

connected ComfoSplitter before

you start working on the ventilation

system. The unit can cause personal

injury when it is open while running.

Make sure the unit cannot switch back

on by accident;

■ Often power is needed on the unit

during troubleshooting while the

unit is open. At all times be aware

of the danger for electrical shocks

and rotating parts. Therefore always

take all the possible precautions to

protect yourself and others during

troubleshooting.

■ Always take ESD-inhibiting measures

when dealing with electronics, such as

wearing an antistatic wristband. The

electronics can be damaged by static

charges;

ESD

■ The FIREPLACE setting is no safety

feature. For safety, a delta-pressure

switch switching off the ventilation in

case of under pressure should still be

installed;

■ Do not change the filters when the

unit is powered without using the filter

wizard. For safety reasons the unit will

stop the ventilation during the filter

replacement instructions.
