VErY IMPOrTaNT:
• The panel manufacturing process impregnates them with chemical agents that have
a characteristic strong odour. To prevent this odour from being transmitted to oc-
cupied spaces, it is recommended that the water recirculation pump be allowed to
run continuously for 24 hours WITHOUT RUNNING THE FAN to wash off the panels.
Afterwards, drain the rinse water before commencing normal start-up.
6.11. INsTallING DaMPEr BOXEs
• Make sure that these can be rotated with gentle pressure, with no binding anywhere in their
range of motion.
• For manually controlled damper boxes, tighten the control sufficiently to prevent the
damper from closing while the unit is running, blocking off the circulation of air.
• If the mixing box is controlled by a servomotor, connect it according to the manufacturer’s
instructions. However, the lever should be removed before installing the servomotor.
7. sTarT-UP PrOCEDUrE
• All access panels on the unit must be closed before starting.
• Make sure that the earth connection is securely connected.
• First turn on the water circulation pump. Wait several minutes to make sure the flow of
circulation remains steady and that there is no variation in the flow. Make sure that any air
bubbles have been drawn to the bleed points and that they have been bled off.
• Make sure that the pressures in the unit do not exceed the maximum pressure for the ex-
changer coils.
• Continue to run the circulation pump for at least 2 hours. Turn off the pump and then re-
move the filter from the unit. To do so, close the appropriate shut-off valves to prevent the
water line from emptying, and to prevent air from getting in. Then clean the filter.
• Take a careful look at the particles trapped in the filter. Make sure that these particles are
not coming from a source that will clog the filter again (such as pipe scale from iron pipes,
hard water deposits, etc.).
• Re-insert the filter, bleed the air from the system and turn the circulation pump on again.
Wait several more minutes to make sure that the flow of water remains steady and there is
no variation in the flow. If good water circulation is not achieved, repeat the steps described
above.
• Before turning on the power to the unit, check to make sure that nothing is hindering the
movement of the regulator dampers if these are operated using a servomotor.
• If the damper are manually operated, make sure by manually tightening the control that
they cannot be closed due to the force of air or anything else while the unit is running.
