Safety precautions
The unit is designed for mounting on a rigid and stable structure.
The unit is mounted with anchor bolts. Make sure that a mounting construction has sufficient load capacity matching the unit weight.
Otherwise reinforce the installation place by beams, etc. If the threaded bolts used for the unit mounting are too short, the unit can
generate abnormal noise and resonate with the ceiling. The suspended bolts must be long enough to prevent resonating.
If the unit connection place to the spiral seam duct is supposed to be the source of abnormal noise, replace the spiral seam air duct with
the flexible one. Optionally the flexible connectors may be used to prevent resonating.
CONDENSATE DRAINAGE
The condensate drain pan in the heat recovery section is equipped with two hoses for extracting the condensed fluid outside the unit.
Connect the pipe, U-trap (not included in the delivery set) and sewage collection system with metal, plastic or rubber connecting pipes.
The pipe slope downwards must be at least 3°.
Fill up the system with water before connecting the unit to power mains!
The U-trap must always be filled with water during the unit operation.
Make sure that the water flows freely into the sewage collection system or otherwise condensed water may build up in the unit during
the heat exchanger operation and cause equipment failure and condensed water outflow into the premises.
The condensate drainage system is designed for normal operation in premises with air temperatures above 0 °C.
If the expected ambient air temperatures are below 0 °C, the condensate drainage system must be equipped with heat insulation and
pre-heating facilities.
