Split-System Condensing Unit Installation Instructions     

      

1000 3000 4000 SERIES

Before Installing Unit

1.  Check all local codes and ordinances that could affect in-

stallation.  The manufacturer assumes no responsibility for 

equipment installed in violation of any code requirements.

2.  Be sure that the electrical data specified on the unit rating 

plate corresponds to what is available at the installation site 

and NEC for installation requirements.

3.  Be sure that the electrical service provided to the building 

can handle the load imposed by the unit.

4.  This unit should be installed in an outside wall for thru-the-

wall installation ONLY. 

5.  NCP condensing units may only be used with indoor evapo-

rator coils utilizing an expansion (TXV) valve.  Self-equaliz-

ing components are required to reduce compressor starting 

problems.  If self-equalizing components are not used, field 

installed hard start kits will be required.

Hard start kits 

MUST

 be compatible with compressors.

.

6.  The unit must be installed with the top level front to rear and 

left to right.

 

In  thru-the-wall  installation,  due  to  the  various  types  of  wall 

construction, it is not possible to provide detailed instructions. 

The following is a list of general requirements and cautions for  

installing these units.

1.  Masonry walls must have a lintel to support the wall.

2.  Extend the unit approximately 3/4” beyond outside surface 

of the wall.  Optional mounting angles can be purchased 

from the factory or field fabricated for locating and mounting 

the unit in the wall.

3.  The  wall  opening  across  the  top  and  bottom  must  be 

flashed. Bottom flashing to cover the full foot print of unit 

and extend up 2’’ on 3 sides.  All openings around the top, 

sides and bottom must be caulked and sealed. Care must 

be taken not to plug the openings in the front of the base 

pan of the unit.

Step 1 - Thru-the-Wall Installation

If the optional wall sleeve is used, caulk the spaces between 

the sleeve and the wall.  Completely fill the clearance between 

the unit and the wall sleeve with a polyurethane foam sealant   

(Follow manufacturer’s suggested application manual).

4.  During  periods  of  rain  and  wind  the  primary  drainage 

path may not be adequate to handle the load.  Secondary  

precautions may also be required but not limited to the  

following:

a. Seal flashing to unit

b. Floor drain

c. Additional field sealing of sheet metal joints

d. Sealing of unused access opening

5.  Clearances to air inlets and outlets must be adequate  

to  ensure  no  air  flow  obstructions  or  recirculation  of  

condenser air flow.

6.  Some architectural designs of buildings will require the unit 

to be mounted behind a decorative grille.  The performance 

(capacity and efficiency) of the unit may be reduced with 

the use of these decorative grilles.

The less resistive these grilles are to air flow, the better the units 

performance will be.

Outdoor louvers provided by others must be approved by NCP 

to maintain unit performance and warranty.  Care must be taken 

to locate coil intake side of unit away from loose debris that may 

clog intake.

7.  If the unit is mounted behind a decorative grille, one or both 

of the following items must be done to eliminate recircula-

tion of air to the unit:

a. The front of the unit must be mounted tight to the inside

    of the architectural grille

b. A barrier 

must

 be provided to prevent recirculation of air

    to the unit (mixing of inlet and outlet air) when the front

    of the unit is mounted back from the inside of the arch-

    tectural grille

8.  The unit 

must

 not be mounted in dead-end hallways or  

areas where there is no fresh outside air circulation.  Cool 

fresh outside air must be provided for best unit operation.  

Thru-the-wall units may not be located where hot exhausts 

from  clothes  dryer  vents,  kitchen  vents,  steam  vents  or  

corrosive fumes could come in contact with coil side of unit.

9.  30”  clearance  is  required  for  service  accessibility  on  the  

inside.  If more than one unit is to be installed in the same 

area  a  min.  of  48’’  vertical  must  be  maintained  between 

units to minimize recirculation of condenser exhaust air.

THE UNIT MUST NEVER BE PLACED ON ITS SIDE OR UPSIDE DOWN AS THE COMPRESSOR OIL WILL RUN IN THE COOLING 

CIRCUIT AND SERIOUSLY DAMAGE THE UNIT.  BASE PAN MUST ALWAYS BE ON THE BOTTOM OF THE INSTALL.
