MCB control board can be controlled by: Stouch remote control panel or MB - GATEWAY web application. Description of remote control panel func
-
tions is provided in the remote control panel technical documentation or on the website www.salda.lt.
It’s required to connect condensate drainage system after hanging or placing of air handling
unit. Insert condensate draining into AHU. Condensate draining must be lubricated with a
sealant (I-VII) and connected to a condensate removal system.
Remove the sticker on the bottom of the unit, which covers a drainage hole. Then open the
unit cover (II) and take out the heat exchanger. Put condensate outlet pipe to EPP casing
through intended hole (V), use silicon gasket (IV). Place from the bottom side gasket and
screw a brass nut on (VII). Screw the nut by holding the pipe with a hand in order prevent
spinning (it’s possible to hold with a screwdriver or 1 Euro coin by putting it in the notch on the
pipe). Screw the nut with a wrench (No. 27) until a top part presses in the EPP casing (level
with a surface or slightly enters into it).
Attention: Screwing force may not exceed 2 Nm.
Pipe (3) (metal pipe should be connected with G3/8 elbow, plastic pipe – with G3/8 elbow or
rubber hose – with strap if the unit is placed on the legs, in other cases condensate hose can
be connected in any direction) should be connected by following order: AHU (1), pipe (2), and
drainage system. Pipes (3) should be bended not less than 3° degrees (1 meter of pipe must
be bended 60 mm downwards)! Before turning on AHU (1) the draining system should be
filled up with at least 0.5 l of water (pipe loop (3) must be always filled with water), also check if
water reaches sewerage system! In other case premise can be flooded during AHU operation!
Draining system must be installed in the premise where the temperature is not lower than 1°C.
If temperature falls below 0°C the draining system should be isolated with thermal isolation.
The pipe loop 2) not necessarily must be mounted below the AHU (1), but below the AHU (1)
level.
Note.
If the collector is situated upstream, install a system with a condensate pump (offered
as an accessory).
D = min 150 mm
Before every heating season the condensate tube shall be
filled with water as indicated during the first start-up! Before

Air Handling Unit uses two types of boards, depending on the
selected product version: miniMCB or miniMCB basic. Their
functionality is different, thus check the board name by the
product version.
