DA 150B Pad Cooling
1 Product Description
DA 150B pad cooling is applied for cooling of large air quantities in tunnel ventilation systems. Fresh air is
directed through pads by means of negative pressure in the house. When cooling is required, the pads are kept
moist with water, which circulates from lower gutter to the top of the pad. Pad cooling can be mounted on the
wall or on the floor.

2.2 Safety Guidelines - Intended Use
These Operating Instructions include the most important information in connection with operating the pad
cooling system in a safe manner.
The relevant guidelines for the prevention of accidents as well as other generally recognised
technical safety and medical regulations for the workplace must be observed.
Check that the safety and functional equipment works safely and correctly:
•prior to start-up
•at appropriate intervals
•after modifications or maintenance.
The specifications outlined by the water and energy utility companies must also be observed.
The system is exclusively intended for cooling/air-conditioning. Usage for other purposes is not intended, like
e.g. pumping other liquids than water. The manufacturer/supplier is not responsible for damage resulting from
this. The user is solely responsible for the use.
To the intended use also belongs the attention of the manual and the adherence to of the maintenance
conditions.
2.3 Electrical System
The installation, service and troubleshooting in connection with electrical equipment must be
carried out by specialists in accordance with applicable national rules - in Europe in accordance
with EN 60204-1 and other applicable EU rules.
The installation of a supply isolator is required for each motor and power supply, so
maintenance of electrical equipment can be carried out in a dead environment. Supply isolator is
not supplied by SKOV A/S.
Mount the pump according to the supplier instruction manual.
The pump must be shielded from direct sunlight (50°C).
All tasks extending beyond the framework of system maintenance may only be carried out by qualified
personnel.
Always isolate the power supply when working on the device and secure against unauthorised reactivation by
another person.
Examine electrical cables for visible damage prior to commissioning.
Replace any damaged lines before putting the device into operation.
Damaged or destroyed plug devices must be replaced by a qualified electrician.
Covering electrical components can give rise to heat concentration with high temperatures which can in turn
destroy the equipment and cause fires.
