DESIGN AND OPERATING PRINCIPLE

The unit is housed in a sound-insulated galvanized steel casing (item 1). The unit casing has 4 mounting brackets with anti-vibration connectors for ceiling or wall mounting (item 5).
The air flow direction is indicated by the arrow on the fan casing.
The bottom side of the casing is covered by a removable cover (item 2), which is secured with 4 bolts (item 4).
A control unit (item 3) is installed on the casing. The power and control cables are pulled through cable glands (item 6). The unit is equipped with a water heater.
On side surfaces of the units there are openings for connecting heat medium supply (item 8.1) and return (item 8.2) pipes.
To facilitate unit’s connection to the heat medium supply and return pipelines, the water heat exchanger can be moved to connect either on the right or left side of the casing, regardless of the location of the control unit.
Models BLAUBOX EC MW 1000-4 S30/31/32, BLAUBOX EC MW 1500-4 S30/31/32, BLAUBOX EC MW 2000-4 S30/31/32, BLAUBOX EC MW 3000-4 S30/31/32, BLAUBOX EC MW 4000-4 S30/31/32 are equipped with end panels (item 7) for connecting the unit to the air duct via flexible inserts.
To install the unit directly into a rectangular air duct, the end panels must be removed.
For ease of electrical connection, the units can be ordered with the control unit located either on right or left side of the casing (right- and left-side versions, respectively, as indicated in the “Designation key” section). If necessary, the control unit can be moved to the other side of the unit casing before being installed in the ventilation system.
The figure below shows the internals of the left and right version of the units with the removable cover removed. The air flow direction is indicated by the arrows.

• The inlet and outlet spigots for duct connections (item 1 and 2 respectively);
• air filter with G4 filtration class (item 3);
• thermostat (item 4);
• water heater (item 5);
• fan unit (item 6).

The unit supplies heated and filtered outdoor air into the room.
The unit uses a frameless radial fan directly driven by an external rotor motor. The fan impeller blades are curved backwards. The motor has built-in thermal protection and requires no maintenance.
The air after filtration passes through a water heater.
To maintain the set air temperature in the supply air duct, the unit’s automatic control system regulates the heat medium flow rate through the water heater.
The unit has double protection against heat medium freezing.
When air temperature drops downstream the heater below the set point, the thermostat is activated, the fan is switched off and the maximum heat medium flow rate is set. When air temperature rises again above the set threshold, the thermostat returns to its original position and the unit resumes its previous operation. Automatic turn on of the unit is possible three times in a row within one hour. After this thermostat is triggered for the fourth time, the fan does not start and the automatic control system displays an error message (code A002). In this situation, operator’s involvement is required to restart the unit.
When the temperature of the heat transfer medium at the heat exchanger outlet drops below a set threshold (the threshold value is set from the remote controller or via the web interface of the automatic control system), the fan stops and the maximum heat medium flow rate is set. When the temperature at the heat exchanger outlet rises above the set threshold again, the unit will resume its previous operation. Automatic turn on of the unit is possible three times in a row within one hour. After the fourth triggering of this thermostat, the fan does not start and the automatic control system displays an error message (code A033).
In this situation, operator’s involvement is required to restart the unit.

MOUNTING AND SET-UP

**** WHILE INSTALLING THE UNIT ENSURE CONVENIENT ACCESS FOR SUBSEQUENT MAINTENANCE AND REPAIR.
The units are installed between the ducts, taking into account the direction of air flow, which is indicated by an arrow on the casing.
BLAUBOX EC MW 700-4 S30/31/32 units are equipped with branch pipes for connection to circular air ducts.
Units BLAUBOX EC MW 1000-4 S30/31/32, BLAUBOX EC MW 1500-4 S30/31/32, BLAUBOX EC MW 2000-4 S30/31/32, BLAUBOX EC MW 3000-4 S30/31/32, BLAUBOX EC MW 4000-4 S30/31/32 are installed in a rectangular air duct system through  lexible inserts.
For direct installation of units BLAUBOX EC MW 1000-4 S30/31/32, BLAUBOX EC MW 1500-4 S30/31/32, BLAUBOX EC MW 2000-4 S30/31/32, BLAUBOX EC MW 3000-4 S30/31/32, BLAUBOX EC MW 4000-4 S30/31/32 in a rectangular air duct system, the end panels must be removed.

WARNING!

• To reduce aerodynamic losses related to air flow turbulence, use shaped reducers in order to reduce or increase the cross-section of air ducts.
• To minimise turbulence-induced air pressure losses, connect the straight air duct sections on both sides of the unit. Minimum straight air duct length: equal to 1 air duct diameter on intake side and 3 air duct diameters on outlet side.
• It is necessary to protect the internal parts of the unit from penetration of foreign objects. For example, install a grill with a cell side size of no more than 12.5 mm to prevent free access to the fan and foreign objects from entering the unit.
• It is recommended to connect the duct through a flexible connection to reduce noise and vibration transmission. Such connections allow compensating for possible mounting inaccuracies when connecting the unit to air ducts.
• The equipment and air ducts that are to be connected must have their own mounting bracket in order to avoid transferring their own weight loads to the unit.

The unit must be mounted so that it can be accessed for service purposes. Enough space must be provided for the cover to open all the way. After removing the screws, the cover will hang on special cables.
Installation is possible on the ceiling or on the wall in such a way that the air flow is horizontal. In this case, the control unit can be located both above and below.
The mounting is carried out at 4 points with mounting brackets. It is recommended to use anchor threaded rods with nuts for fastening the unit. The vibration mounts on the unit casing must fit snugly against the ceiling or wall surface.
Fasteners for the unit mounting are not included into delivery set and should be ordered separately. While choosing fasteners consider the material of the mounting surface and the unit weight. For selection of the fasteners for unit mounting please refer to a service technician.
Install the outdoor temperature sensor in the air duct downstream of the unit along the air flow. The units are available in the right- or left-side versions depending on the location of the control unit relative to the air flow direction.
The units are assembled in such a way that the water heater connections are placed on the opposite side of the control unit.
The unit design allows moving the control unit and water heater to the opposite side of the casing. This allows for more efficient placement of equipment and communications during the installation of the ventilation system.

Connecting the water heater
Supply and return pipes must be connected in such a manner so that the direction of the heat medium flow would be opposite to the air flow (counter- flow connection). This allows reaching the maximum power output of the water heater. All technical characteristics of the units are given for counter-flow connection. With a direct-flow connection, the water heater has a reduced power output and becomes more resistant to freezing.
Connection points for the heat medium inlet and outlet are marked with stickers on both sides of the casing.
Heat exchanger’s connection to the heat medium supply system must allow for easy disassembly when the heat exchanger is removed for maintenance.
The following is a typical diagram of the heat medium supply system (not included in the delivery set) for connecting the water heater.

TECHNICAL MAINTENANCE

DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE OPERATIONS!
MAKE SURE THE UNIT IS DISCONNECTED FROM POWER MAINS BEFORE REMOVING THE PROTECTION
PRIOR TO COMMENCING ANY TECHNICAL MAINTENANCE PUT UP A PROHIBITORY SIGN ON THE FAN STARTING PANEL: “DO NOT SWITCH ON! MEN AT WORK!”
**** AVOID LIQUID SPILLS ON THE MOTOR! DO NOT USE AGGRESSIVE SOLVENTS AND SHARP OBJECTS FOR CLEANING!

Maintenance operations of the unit are required 3-4 times per year. They include general cleaning of the unit and the following operations:

1. Filter maintenance (3-4 times per year).
   Dirty filters increase air flow resistance, which leads to a decrease in the supply of supply air to the room and creates preconditions for occurrence of faults. Filters should be replaced as they become dirty, but no less than 3-4 times a year.
   To change the filters, remove the unit casing cover (item 2 in the section “Unit design and operating principle”).
   Rotate the lock that holds the filter. Carefully remove the dirty filter.
   Install new filters and cover in reverse order.
   For new filters, contact the Seller.

2. Fan maintenance (once per year).
   Even in case of regular maintenance of the filters, some dust may accumulate inside the fans and reduce the fan performance and supply air flow. Clean the fans with a soft brush or cloth. Do not use water, aggressive solvents, or sharp objects as they may damage the impeller.

3. Ductwork system maintenance (once in 5 years).
   Even regular fulfilling of all the maintenance operations prescribed above may not completely prevent dirt accumulation in the air ducts, which reduces the system capacity. Duct maintenance means regular cleaning or replacement.

4. Control unit maintenance (as required).
