Remedy
Check and confirm that the caravan main
power is switched on. Check the AC switch
and the safety circuit breaker on the caravan.
All these should be switched on.
To protect itself from damage, the unit may
switch off (return to standby) if power is
momentarily interrupted. Ensure that the
caravan is connected to a clean power supply
within the specified power operating range
before attempting to restart the unit.
Remote control instructions are confirmed by a
beep and the power LED blinking once. There
is a short delay between a command being
sent and the unit responding. Ensure that
the remote control is pointed towards the air
distribution unit from a distance less than 8m.
Replace the batteries if necessary.
The external fan is adjusted based on system
and ambient conditions. Where possible, the
exterior fan will switch to low speed for less
disturbance to you and your neighbours. In
heating mode, the exterior fan may switch off
periodically to allow condensate to drain away
Check that the condenser (on the roof top) is
not blocked with dust, leaves or rubbish. Clean
if neccesary.
Inspect the indoor air filter on the inner air distri-
bution unit. Clean or replace if necessary.
Use within operating temperature range and
follow guidelines in section 3.1
Ensure that the unit is being used within it's
operating temperature range. Refer to the
technical data for details of the operating
ranges in section 3.1.
