Intermittent operation during
very hot & very cold days
RV is too large for the air
conditioner
Duct lengths are too long
The air will not start flowing
until the coil has warmed up
sufficiently, this is to prevent
cold draughts
Fan is set to High speed
Condensate is being generated

maximum ducting lengths.
Take action to reduce your peak heat load –
extend awnings, close blinds, windows &
hatches, start air conditioner earlier in the
morning.
Discuss your expected heat load with your
caravan supplier and size the air conditioning
capacity to suit.
Outside air temperature exceeds the unit's
operating temperature range.
Discuss expected heat loss with your caravan
supplier and size air conditioning capacity to
suit.
Outside air temperature is below the unit's
operating temperature range.
During cooling on very hot days the
compressor overload may be activated. This is
to protect the unit. Take all steps to reduce
heat load on caravan.
During heating on cold mornings the unit will
periodically enter automatic de-ice mode to
clear ice from its outside coil. Normal
operation will resume once ice has been
melted.
The Sandpiper is intended to provide spot
cooling and relief to certain areas immediately
adjacent to the outlets, it is not intended to
lower the temperature in all areas of the RV. It
may do this in some cases but that will depend
on the heat load of the van which is affected
by size, amount of windows, insulation,
persons in the van, direct sunlight etc.
Reduce duct lengths as it will take time to
cool/heat the ducting before cool/warm air
will flow from the outlets, refer to instruction
manual for recommended maximum duct
lengths.
This is normal operation.
Change fan speed to Medium or Low, however
the largest cooling/heating capacity is
generated when the unit is set to High speed.
Don't route the ductwork near any heat
producing appliances such as the rear of a
refrigerator.
A small amount of moisture is normal as the
