Right-hand version
The air handling units are supplied in the right-hand or left-hand
version as shown in Fig. 2a and 2b. In the left-hand version (Fig.
2b), the components marked with an asterisk change func-
tion and designation (the components are named according to
whether the function is for supply air or extract air.).
The arrangement of the components and their desig-
nations
1 EXHAUST AIR* (In left-hand version: Supply air)
2 OUTDOOR AIR* (In left-hand version: Extract air)
3 Pressure sensor, supply air filter* (Position on function selec-
tor switch = 3)
4 Supply air filter*
5 Temperature sensor, outdoor air*
6 Electrical equipm. cubicle with control unit
7 Valve actuators, shut-off and bypass dampers
8 Handheld terminal
9 Temperature/relative humidity sensor, extract air*
(RECOfrost only)
10 Extract air filter*
11 Temperature sensor, supply air (to be mounted in supply air
duct)
12 EXTRACT AIR* (In left-hand version: Outdoor air)
13 SUPPLY AIR* (In left-hand version: Exhaust air)
14 Extract air fan* with motor and motor controller
15 Pressure sensor, extract air fan* (Position on function selec-
tor switch = 1)
16 Extract air/exhaust air pressure sensor (applies only to RECO-
frost, function selecter switch position = C)
17 Plate heat exchanger with bypass and shut-off damper
18 Pressure sensor, supply air fan* (Position on function selector
switch = 2)
