• Make  provisions  for  disconnecting  and  cleaning  of  the  primary  drain  line  should  it

become necessary.

• Install a 2 in. trap in the primary drain line as close to the unit as possible. Make sure

that  the  top  of  the  trap  is  below  connection  to  the  drain  pan  to  allow  complete
drainage of pan.

IMPORTANT: Do not operate unit without a drain trap (see Figure 12). The conden-
sate  drain  is  on  the  negative  side  of  the  blower,  therefore,  air  being  pulled  in
through the condensate line will prevent positive drainage without a proper trap.

• Auxiliary drain if used should be run to a place where it will be noticeable if it become

operational. Occupant should be warned that a problem exists if water should begin
running from the auxiliary drain line.

• Test  condensate  drain  pan  and  drain  line  after  installation  is  complete.  Pour  several

quarts of water into drain pan, enough to fill drain trap and line. Check to make sure
drain pan is draining completely, no leaks are found in drain line fittings, and water is
draining from the termination of the primary drain line.

7.0 AIR FILTER

The  unit  internal  air  filter  should  only  be  used  if  the  unit  is  readily  accessible  for  filter
cleaning or replacing.

• If  unit  is  not  readily  accessible  for  filter  maintenance,  a  remote  filter  should  be

installed in the return air system.

• If  a  remote  filter  is  installed,  it  should  be  sized  for  a  maximum  of  300  feet/min.  air

velocity for the CFM required..

IMPORTANT: Do not operate system without a filter. A filter is required to protect
the coil, blower and internal parts from excessive dirt and dust.

• See  unit  position  figures  for  location  of  filter  in  unit  cabinet  and  service  panel  giving

access to unit filter.

IMPORTANT NOTE:

• In a downflow configuration the internal air filter must not be used.

• A remote air filter should be installed in the return air system

• The remote air filter should be sized for a maximum of 300 feet per minute of air veloci-

ty for the CFM required.

8.0 AIRFLOW PERFORMANCE

Airflow  performance  data  is  based  on  cooling  performance  with  a  coil  and  filter  in
place.  
Select  performance  table  for  appropriate  unit  size,  voltage  and  number  of  electric
heaters to be used. Make sure external static applied to unit allows operation within the min-
imum and maximum limits shown in table on next page for both cooling and electric heat
operation. For optimum blower performance, operate the unit in the .2” to .5” in. W.C. exter-
nal static range. In general, the indoor motor speed tap should be as shown in table for the
appropriate cooling capacity shown. Always check to make sure proper motor speed tap is
connected as units are shipped from the factory connected for high speed operation (Speed
Tap 5).
