6 Maintenance
Ensure complete electrical isolation before performing any maintenance activity and always follow
guidelines and instructions as given in the air cooler product manual AHE00042.
6.1 Fan replacement
Unplug power cable. Unscrew fixing bolts and
remove old fan. Mount new fan in identical
position. Use an anti-corrosion compound when
remounting the fixing bolts.
Replace power cable connector when the new
fan has been mounted.
6.2 Driptray and side covers
Driptrays can be opened for inspection, cleaning
and maintenance purposes. Always disconnect
drain line before opening the driptray.
Prior to opening, run a full defrost cycle to
remove any ice in the driptray. Ensure the drip-
tray is empty before opening. The weight of any
leftover water could injure the service operator if
the driptray fell open accidentally.
Both CS200 and CS300 models are fitted with
an integrated fan plate/driptray. To open this
driptray, first loosen screws 'c' (CS300 only)
and remove bolts 'a'. Then lower the driptray.
Respect the maximum opening angle (90°) to
avoid damage to the driptray hinges.
For CS300 models, side covers can be removed
for inspection, cleaning and maintenance pur-
poses. To remove side covers, open driptray
and loosen fixing screws 'b'. CS200 models are
fitted with a removable side hatch to access the
expension valve.
