Page 5: Duct Heat Insulation
The ventilation engineer calculates the insulation requirements depending on the placement of the ducts and the air temperatu- res. When the insulation materials are designed, it must be taken into account that the extract air temperature may decrease significantly below zero degrees. The Optimizer software, which is available from Ensto Enervent’s website, can be used to calculate the extract air temperature with different outside air temperatures. Calculation software available from insulation material manufacturers can also be used when designing the insulation material thickness. -

Page 8: Draining The Ventilation Unit
DRAINING THE VENTILATION UNIT All Enervent-units with cooling must be drained. We recommend that also other units are drained. When air cools down (condenses) condense water forms i.e. in winter time when the humid inside air meets the cold heat recovery wheel or if the unit is equipped with cooling. -
Page 9: Defining Addresses For Operating Panels
DEFINING ADDRESSES FOR OPERATING PANELS Four (4) operating panels can be connected to an ventilation unit with EDA-control. If an unit is controlled with more than one panel, Modbus-addresses have to be defined for the panels in order for them to work in parallel. The address is defined with the short-circuit plugs delivered with the panel. -
Page 10: User Guide
USER GUIDE STARTING THE UNIT Before the unit is ready for use the following installations should take place: Assemble the unit as stated in the chapter Installation in this manual. Connect the drainage outlet with its own hose to an outflow supplied with a water lock (if the unit ventilates a space with swimming pool or if it is equipped with cooling). -

Page 27: Heat Exchanger Belt Replacement
HEAT EXCHANGER BELT REPLACEMENT There is a spare belt attached to all heat exchangers. In order to take use of the spare belt the heat exchager needs to be removed from the ventilation unit. Loosen the bayonet socket before removing the heat exchanger from the unit. Open the mainte- nance hatch (see below) and release the spare belt from the hold- ers. -
Page 28: Troubleshooting
TROUBLESHOOTING SUPPLY AIR COLD AFTER HEAT RECOVERY (TE05 min) Reason Action Belt of the heat exchanger is broken. Replace the belt. Belt greasy, causing slippage. Contact a service representative. * The extract fan has stopped. Contact a service representative. * The extract air filter is blocked. - Page 29 FREEZE RISK OF WATER COOLER (E45 min) Reason Action The circulation water pump has stopped. Activate the pump. If the problem persists, contact a service representative. Belt of the heat exchanger is broken. Replace the belt. Adjustor of water cooler’s valve defective. Contact a service representative.
