4.3 Electrical connection (supply voltage 230 VAC)
The Coolfog Maxi must be connected to an earthed wall socket that forms part of an earthed
electrical system.
If desired, the wall socket can be fitted with a timer switch for setting activation times.
Electrical cables must not be rolled up due to the risk of overheating.
4.4 Water connections
Water intake
•The water level inside the Coolfog Maxi is regulated by a float valve. This is located inside the
Coolfog Maxi. The water supply connection is on the exterior of the Coolfog Maxi. This is a 3/8”
threaded connection.
•The Coolfog Maxi and its water connections must be installed in a frost-free area in order to
guarantee effective operation.
•If there are major temperature fluctuations between the Coolfog Maxi and its surroundings,
condensation can form on the exterior of the Coolfog Maxi and on the air outlet pipes. This can
be prevented by insulating the Coolfog Maxi and the air outlet pipes.
•The Coolfog Maxi must be included in company-specific risk management related to legionnaire’s
disease and in the corresponding Legionnaire’s Disease containment plan, set up within the
context of legionnaire’s disease prevention.
•Distilled water cannot be used, as it will damage the water sensor on the Coolfog Basic.
Important!
Legislation and regulation with respect to Legionnaire’s Disease can differ per country. The client is
responsible for observing applicable legislation and regulations.
Water outlet
•A water outlet connection with a ½” ball valve is fixed to the exterior of the Coolfog Maxi. Its
purpose is to allow drainage of the Coolfog Maxi during maintenance or if the equipment is not
used for a long period of time.
•A level meter tube is fixed to the exterior of the Coolfog Maxi. The water level inside the Coolfog
Maxi can be determined with this level meter tube, while it has a safety function that guards
against water levels exceeding the maximum. The top of this level meter tube must not be closed
off.
4.5 Air connections
Air intake
The Coolfog Maxi is suitable for direct and indirect humidification.
Direct humidification requires a clean air supply free of water particles. Any possible air ducts must
not be obstructed.
If indirect humidification is applied, the Coolfog Maxi is placed outside the humidification area. A
sealed air system is used to extract the air from the area in question. This is then fed back into the
area, along with the added mist. This involves the recirculation of the humidified air. With the
exception of the humidity being brought to the desired level, the atmosphere inside the area does
not change. When installing an extraction pipe in the humidification area, care must be taken to
ensure that the mist from the Coolfog Maxi is not immediately drawn in by the extraction pipe. The
system requires an unobstructed air supply free of water particles. The manufacturer recommends
the use of a mist distribution pipe.
