We reserve the right to alter specifications without notice.
Warning
The inspection doors on the filter/fan sections must not
be opened while the air handling unit is in operation.
Stop the unit when it is operating normally via the hand-
held terminal.
Wait until the fans have stopped rotating before opening
the inspection door.
The air pressure inside the filter/fan section is positive,
which means that the door can fly open.
Keep the key at a safe spot separate from the air han-
dling unit.
1.3 Safety Guards
The cover of the electrical equipment cubicle, and when applica-
ble the junction hood, serve as safety guards on the size 04/05
and 08 one-piece units with rotary heat exchanger (RX), as well
as on all the other variants (PX/CX/SD). On the size 12, 14/20,
25/30, 35/40, 50/60, 70/80 and 100/120 one-piece air handling
units with rotary heat exchanger (RX), the lockable door over the
electrical equipment cubicle, and if applicable the junction hood,
serve as safety guards.
Only a qualified electrician or trained service technicians shall be
allowed to remove the safety guards.
Warning
The power supply to the unit shall be isolated by switch-
ing off the safety isolating switch before removing the
safety guard.
When the air handling unit is operating, the safety guards
must always be mounted, all inspection doors must be
closed, and the junction hood on the top of the unit must
be mounted.
1.4 Glycol
Glycol is used in the GOLD air handling units with coil
heat exchangers.
Warning
Never pour glycol down a drain; collect it in a recepta-
cle and leave it at a recycling centre, petrol station, etc.
Glycol is highly dangerous to consume and can cause
fatal poisoning or damage the kidneys. Contact a doctor!
Also avoid breathing glycol vapour in confined spaces. If
you get glycol in your eyes, flush them thoroughly with
water (for about 5 minutes). If glycol splashes on your
skin, wash with soap and water.
1. Safety Instructions
All staff concerned must acquaint themselves with these instruc-
tions before beginning any work on the unit. Any damages to
the unit or parts of it due to improper handling or misuse by the
purchaser or the fitter cannot be considered subject to guarantee
if these instructions have not been followed correctly.
Warning
Only a qualified electrician or service personnel trained
by Swegon shall be permitted to modify the air handling
unit in conjunction with electrical installations or the
wiring of external functions.
1.1 Safety Isolating Switch/Main
Switch
On the size 04/05, 07/08, 11/12, 14/20 and 25/30 GOLD one-
piece air handling units with rotary heat exchanger (RX) or plate
heat exchanger (PX), the safety isolating switch is externally
located on the junction hood.
On the size 35/40, 50/60, 70/80 and 100/120 GOLD one-piece
air handling units with rotary heat exchanger (RX), the safety
isolating switch is externally located on the centre section of the
unit.
On the size 35/40 GOLD one-piece air handling units with coil
heat exchangers (CX), the safety isolating switch is located
on the left side of the electric equipment cubicle in the centre
section of the unit. On the size 50/60, 70/80 and 100/120 air
handling units, the safety isolating switch is located in a plastic
enclosure in the centre section of the unit.
On the size 04-80 GOLD SD separate supply air and extract
air handling units, the safety isolating switch is located on the
inspection side by the fan section's inspection door. On the size
100/120 units, the safety isolating switch is located in a plastic
enclosure on the inspection side of the air handling unit.
The air handling unit should normally be started and stopped
from the hand-held terminal; not by switching the safety isolat-
ing switch on and off.
Always switch off the safety isolating switch before servicing the
unit if not otherwise specified in the pertinent instructions.
1.2 Risks
Warning
Before carrying out any work, make sure that the power
supply to the air handling unit has been switched off.
Risk areas with moving parts
Moving parts are fan impellers, drive pulley for the rotary heat
exchanger, if fitted, and by-pass/shut-off damper of the plate
heat exchanger, if fitted.
The lockable inspection doors serve as protection from contact
with the fans and protection for the heat exchanger. If the ducts
are not firmly connected to the fan outlets, the outlets must be
firmly fitted with a safety guard (wire mesh screen).
