2 Safety precautions
2.1 Safety Isolating Switch/Main Switch
The safety isolating switch is placed on the door of the
electric cubicle. The electric cubicle is located inside the
upper inspection cover on the inspection side of the cool-
ing unit (decal is affi xed on current inspection cover).
The safety switch should not be used for start or stop of
the cooling unit.
Ensure that the cooling unit is shut off by stopping the
air handling unit or by temporarily shutting off the cool-
ing unit via the hand-held micro terminal, see the GOLD
operation and maintenance instructions.
When this has been carried out, the current can be iso-
lated with the safety switch. For easy access to the safety
switch, open the relevant inspection cover by unscrewing
the knobs in the lower edge of the cover. Take hold of the
cover in the handle and pull the cover carefully outwards.
N.B.! Have a good grip on the cover so that it will not fall
down!
Important
Always switch off the safety isolating switch before ser-
vicing the unit if not otherwise specifi ed in the pertinent
instructions.
2.2 Risks
!
Warning
Before carrying out any work, make sure that the power
supply to the air handling unit has been switched off.
!
Warning
Under no circumstances shall the refrigerant circuit be
opened by unauthorised personal, since there is gas
under high pressure in the circuit.
Risk areas with refrigerant
Risk area for refrigerant is in principal inside the entire
cooling unit. For handling when leakage, see section 7.2
Handling of refrigerant.
Refrigerant used is R 410A.

Warning
The upper inspection cover on the backside of the unit
must not be opened while the cooling unit is in opera-
tion, since it functions as protective screen for condenser
fans.
The lower cover panel on the backside of the cooling
unit may not be dismantled when the air handling unit
and/or the cooling unit is operating. The cover panel is
likely to fl ip open and injure personnel.
2.3 Electrical equipment
The electrical equipment of the cooling unit is mounted
in a separate electrical cubicle inside the upper inspection
cover on the inspection side of the cooling unit. For easy
access to the electrical equipment, open the inspection
cover by unscrewing the knobs in the lower edge of the
cover. Take hold of the cover by the handle and pull the
cover carefully outwards.
N.B.! Have a good grip on the cover so that it will not fall
down!
2.4 Authorisation
Only authorized electricians shall be permitted to install
electrical wiring in the cooling unit.
Servicing inside or reparation of the refrigerant circuit may
only be performed by technicians of an accredited cooling
fi rm.
Other service work in the cooling unit should only be per-
formed by service personnel trained by Swegon.
2.5 Decals
The type number mark with type designation, serial
number, refrigerant volume and more is affi xed on the
inspection side of the cooling unit.
