SAFETY CONSIDERATIONS
Improper installation, adjustment, alteration, service, maintenance,
or use can cause explosion, fire, electrical shock or other conditions
which may cause death, personal injury or property damage.
Consult a qualified installer, service agency, or your distributor or
branch for information or assistance. The qualified installer or
agency must use factory--authorized kits or accessories when
modifying this product. Refer to the individual instructions
packaged with the kits or accessories when installing.
Follow all safety codes. Wear safety glasses, protective clothing
and work gloves. Use quenching cloths for brazing operations.
Have fire extinguisher available. Read these instructions
thoroughly and follow all warnings or cautions attached to the unit.
Consult local building codes and the current editions of the
National Electrical Codes (NEC) NFPA 70.
In Canada, refer to the current editions of the Canadian Electrical
Code CSA C22.1.
Recognize safety information. This is the safety--alert symbol
When you see this symbol on the unit and in instructions or
manuals, be alert to the potential for personal injury.
Understand the signal words DANGER, WARNING and
CAUTION. These words are used with the safety-- alert symbol.
DANGER identifies the most serious hazards which will result in
severe personal injury or death. WARNING signifies hazards
which could result in personal injury or death. CAUTION is used
to identify unsafe practices, which may result in minor personal
injury or product and property damage. NOTE is used to highlight
suggestions which will result in enhanced installation, reliability, or
operation.

WARNING
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
or death.
Before installing, modifying or servicing system, always turn
off main power to system. There may be more than one
disconnect switch. Lock out and tag switch with a suitable
warning label.
!
CAUTION
CUT HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care and
wear appropriate protective clothing and gloves when
handling parts.
IMPORTANT: Nitrogen can leak out through the plug. This does
not indicate a leaking coil nor warrant return of coil.

INTRODUCTION
Use these instructions to install Model CSPHP duct coils in
horizontal position. (See Fig. 1.) It is easily adaptable to most types
of existing forced--air heating systems, or can be installed in an
independent air-- cooling system.

Step 2 — Insulate and Vapor--proof Duct
Externally insulated ductwork must have an adequate vapor seal
for summer operation. This is particularly important where the duct
is exposed to high humidity conditions in attics, vented crawl
spaces, unconditioned basements and utility rooms. The vapor seal
prevents condensation in the insulating material and subsequent
loss of insulating value. Properly installed heating supply ducts
should already have adequate insulation against excessive heat
loss. This same insulation should, therefore, be satisfactory in the
summer for protection against heat gain. However, depending on
the specific installation, it may be desirable to add to the insulation.
Step 3 — Install Coil in Supply Air Duct
NOTE: For cooling--only units, coil can be installed in either
airflow direction. Heat pump applications require specific airflow
direction to obtain performance. See Fig. 1.
a. When the connecting air supply duct is smaller than the coil
inlet opening, construct transition piece so that vertical and
horizontal dimensions of transition piece do not increase
more than 30 angle. If connecting outlet duct is smaller
than outlet opening of coil, limit transition to maximum of
45 angle.
b. Provide at least 3 ft (.9m) of straight ductwork preceding
coil inlet.
c. Support coil from floor or suspend it. When coil is suspen-
ded, provide adequate hangers to hold coil.
NOTE: When coil is installed over a finished ceiling or living
area, a secondary condensate pan must be constructed and installed
under entire coil section.

INSTALLATION
Step 1 — Check Existing Ductwork
Inspect the previously installed air distribution system for heating
to determine its suitability for cooling. Existing heating ductwork
may have to be modified and insulated to provide better air
distribution for cooling.

WARNING
PERSONAL INJURY HAZARD
Failure to follow this warning could result in personal injury.
Wear eye protection.
Coil is factory charged with 15 psi nitrogen. The coil is under
pressure and TXV screen is in place behind liquid line plug.
DO NOT removed liquid line plug first; always remove the
suction line plug first to depressurize the coil.
NOTE: Factory nitrogen charge may escape past rubber plugs
during storage. This does not indicate a leaking coil nor warrant
return of the coil.
Size and install refrigerant lines according to information provided
with outdoor unit. Coil connection tube sizes are shown in Table 1.
Route refrigerant lines to the coil in a manner that will not obstruct
service access to the unit or removal of the filter.
Do not use damaged, dirty, or contaminated tubing because it may
plug refrigerant flow--control device. ALWAYS evacuate the coil
and field--supplied tubing before opening outdoor unit service
valves.
Use field--supplied, refrigerant--grade tubing for connection to
outdoor units. Suction tube must be insulated. Do not use
damaged, dirty, or contaminated tubing because it may plug
refrigerant flow-- control device. ALWAYS evacuate the coil and
field--supplied tubing before opening outdoor unit service valves.
Step 5 — CONNECT REFRIGERANT, LIQUID,
and S UCTION LINES
For matched and mismatched systems, use line sizes recommended
in outdoor unit Installation Instructions.
