B. LOCATION AND PREPARATION OF THE UNIT

(INFORMATION APPLICABLE TO 

HEAT PUMPS ONLY

)

This Heat Pump has been designed and manufactured to
withstand and operate in severe winter conditions.
However, there are precautionary steps which should be
taken at the time of installation which will help assure
the efficient operation of the unit. 

It is recommended

that these precautions be taken for units being
installed in areas where snow accumulation and
prolonged below freezing temperatures occur.

1.

Units should be elevated 3 to 12 inches above the pad or
rooftop, depending on local weather. This additional height
will allow better drainage of snow and ice (melted during
defrost cycle) prior to its refreezing. 

This should prevent a

build-up of ice around the unit which occurs when unit is
not elevated. 

Insure that drain holes in unit base pan

are not obstructed preventing draining of defrost
water.

2. If possible, avoid locations that are likely to accumulate

snow drifts. If not possible, a snow drift barrier should be
installed around the unit to prevent a build-up of snow on
the sides of the unit and should be of sufficient distance
from the unit to prevent restriction of airflow to and from
the unit. Also allow for proper maintenance space. The
barrier should be constructed of materials which will
blend in with the building design.

3. Avoid locating the unit where condensation and freezing

of defrost vapor may annoy the customer. For instance,
installing the unit under a bedroom, kitchen, or picture
window may be annoying to the customer since conden-
sate and fog will occur during the defrost cycle.

4. Avoid locating the unit under the eaves or other overhead

structures as sizeable icicles may form and the unit may
be damaged by these falling icicles.
