_\ "_____SAFETYPRECAUTIONS
_y_ • This Zoneline must be properly
installed ira accordance with tile
Installauon Instrucuons before it is
used. See the Installation Instructions
ira tile back of this manual.
Replace immediately all electric service
cords that have become frayed or
otherwise damaged. A damaged power
supply cord must be replaced with a
new power supply cord obtained from
the mamffacturer and not repaired.

_._]_en the lever is in the CLOSEposition, only the
air inside the room is circulated and filtered.
\._]]en the lever is in the OPEIVposition, some
outdoor air will be drawn into the room. This

AboutHeat Pumps(onsomemodels)
Heat pumps can reduce operating costs by
exchanging heat ti'om the outside air----even
when the outside temperature is below
fl'eezing-- and releasing that heat ind{){n_.
To get the best economic benefit ti'om yore" heat
I)ump, don't change the room themmstnt setting
very often. Raising the heat setting 2-3 degrees
will cause the Zoneline to use its electric heating
elements in order to reach the new temperature
setting quickly.
There is a three minute minimum compressor
mn time at any setting to prevent short cycling.
The indoor tim motor stnrts befin'e the
compressor and stops after the compressor
cycles off.
The electric heating elements use much
more electricity than heat i)umps and cost
II/OI'e to operate.

Careand cleaning, gecem
Turnthe Zoneline offand disconnectthepower supplybeforecleaning.
Indoor/Outdoor Coils
The exhaust coils on the Zoneline should be
checked regularly: If they are clogged with dirt or
soot, they may be protessionally steam cleaned by
w)ur (;E service center; You will need to remove
the refit fl'om the case to inspect the coils
because the dirt build-u I) occm_ on the
exhaust side.
-- Outdoor coils
Have the ceils cleaned regularl,_
Drain
Clean the drain system regularly to
prevent clogging.
Base Pan
In some installations, dirt or other debris may be
blown into the refit fl'om the outside and settle in
the base pan (the bottom of the refit).
In some areas of the United States, a "gelqike"
subst;mce may be present in the base pan.
Check it periodically and clean, if necessa_w:
Air Filters
Tomaintain optimum performance, change the filter at least every30 days.
The most important thing )'ou can do to Toremove
maintain the Zoneline is to change the filter at and replace
least eve_w 30 days. Dirty filte_ reduce cooling, the filter:
heating and air flow.
Changing the filter will: Decrease cost of operation,
save energai, prevent clogged heat exchanger
coils and reduce the risk ot premature
component tailm'e.
CAUTION: Oonotoperatethe
Zoneline wi_out the filter in place. If a filter
becomes tornor damaged, It should be replaced
immediately.
Operating without the filter in place or with a
damaged filter will allow dirt and dust to reach
the indoor coil and reduce the cooling, heating,
airflow and efficiency of the unit.
Replacement filtex_ should be imrchased fl'om
your local retailer where air conditioner and
lilI'IlaCe accessolJes are sold.
