1. Safety Instructions
All staff concerned must acquaint themselves with these
instructions before beginning any work on the unit. Any
damages to the unit or parts of it due to improper han-
dling or misuse by the purchaser or the fitter cannot be
considered subject to guarantee if these instructions have
not been followed correctly.
Warning
Only qualified electricians or service personnel shall
be permitted to carry out any work on the electrical
system or wire external functions in the air handling
unit.
1.1 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 ex-
changer. If the ducts are not firmly connected to the fan
outlets, the outlets must be firmly fitted with a safety
guard (wire mesh screen).
Warning
The inspection doors on the filter/fan sections must
not be opened while the unit is operating.
Wait until the fans have stopped before opening
the door.
Positive pressure inside the fan section will other-
wise cause the door to fly open.
Keep the key at a safe spot separate from the air
handling unit.
1.2 Glycol
Glycol is used in the SILVER C air handling units with coil
heat exchangers.
Warning
Never pour glycol down a drain; collect it in a re-
ceptacle and leave it at a recycling centre, petrol
station, etc. Glycol is highly dangerous to consume
and can cause fatal poisoning or damage the kid-
neys. Contact a doctor! 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.
