AIR HANDLER TECHNOLOGY AT ITS FINEST
The PF4MN fan coil has the proven technology of Payne fan coil units
with R-410A refrigerant as well as vertical and horizontal applications.
The design features contoured condensate pans with rugged drain
connections, ensuring that little water is left in the unit at the end of the
cooling duty cycle. The lack of standing condensate and corrosion free
pans improves IAQ and product life, features homeowners appreciate.
Standard features include grooved tubing and louvered fins. Coil
circuiting has also been updated to make the most of all Payne heat
pumps and air conditioners. Units come with solid state fan controls,
1-inch (25mm) thick insulation with R-value of 4.2, multi-speed motors,
and fully-wettable coils. Units can accommodate factory- and/or
field-installed heaters from 3 to 30 kW.
Assembled at the factory compliant with low leak requirements of less
than 2% cabinet leakage rate at 0.5 inches W.C. and 1.4% cabinet
leakage rate at 0.5 inches W.C. when tested in accordance with
ASHRAE 193 standard.
The PF4MN fan coil design is loaded with popular features. These fan
coils utilize the latest in electronic commutation motor (ECM)
technology through the use of high efficiency, multi-tap ECM motors
allowing reliable air delivery with increased static pressure. It comes in a
pre-painted (taupe metallic) galvanized steel casing and a
factory-supplied power plug for ease of installation. The unit is shipped
with a R-410A refrigerant TXV (sizes 18–60).
STANDARD FEATURES

2% when tested at 0.5 inches W.C., and cabinet air leakage less than
1.4% at 0.5 inches W.C. when tested in accordance with ASHRAE
193 standard.
• Installation-flexible, multipoise units
• Horizontal hanging provisions on cabinet
• No tools required to access filter.
• Newly improved filter rack area filter door insulation added for

NOTES:
1. Airflow based upon dry coil at 230V with factory-approved filter and electric heater (2 element heater sizes 018 through 036, 3 element heater sizes 042 through 060).
2. To avoid potential for condensate blowing out of drain pan prior to making drain trap:
Return static pressure must be less than 0.40 in. wc. Horizontal applications of 042 - 060 sizes must have supply static greater than 0.20 in. wc.
Airflow above 400 cfm/ton on 048-060 size could result in condensate blowing off coil or splashing out of drain pan.
3. At higher pextstats (above 0.6 in/wc), water blowoff is more likely to occur depending on the user’s setup.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

3. SHC is based on 80_F (27_C) db temperature of air entering coil. Below 80_F (27_C) db, subtract (Correction Factor x CFM) from SHC. Above 80_F (27_C) db, add (Correction Factor x CFM) to SHC.
4. Bypass Factor = 0 indicates no psychometric solution. Use bypass factor of next lower EWB for approximation.

The airflow performance data was developed using fan coils with 10-kW electric heaters (2 elements) in the 018 through 036 size units and 15-kW heaters (3 elements)
in the 042 through 061 size units. For fan coils with heaters of a different number of elements, the external available static at a given CFM from the curve may be
corrected by adding or subtracting available external static pressure as indicated above.

* Use copper wire only. Use 75_C only in this application. When using non-metallic (NM) sheathed cable, wire size required should be based on that of 60_C conductors, instead of wire sizes
shown in table above per NEC Article 336-26.
NOTE: If branch circuit wire length exceeds 100 ft (30 m), consult NEC 215-2 to determine maximum wire length. Use 2% voltage drop.

* All circuit breakers are 2 pole.
When using units with 20-, 24-, and 30-kW electric heaters, maintain a 1-in. (25mm) clearance from combustible materials to discharge plenum and ductwork and maintain a distance of 36-in
(914mm) from the unit. Use an accessory downflow base to maintain proper clearance on downflow installations. Use flexible connectors between ductwork and unit to prevent transmission of
vibration. When electric heater is installed, use heat resistant material for flexible connector between ductwork and unit at discharge connection. Ductwork passing through unconditioned space
must be insulated and covered with vapor barrier.

Accessory Kits Description – Suggested and Required Use
1. Disconnect Kit
The kit is used to disconnect electrical power to the fan coil so service or maintenance may be performed safely.
SUGGESTED USE: Units for 3- through 10-kW electric resistance heaters and cooling controls.
2. Downflow Base Kit
This kit is designed to provide a 1-in. (25mm) minimum clearance between unit discharge plenum, ductwork, and combustible materials. It also
provides a gap-free seal with the floor.
REQUIRED USE: This kit must be used whenever fan coils are used in downflow applications.
3. Downflow Conversion Kit
Fan coils are shipped from the factory for upflow or horizontal-left applications. Downflow conversion kits provide proper condensate water
drainage and support for the coil when used in downflow applications. Separate kits are available for slope coils and A-coils.
REQUIRED USE: This kit must be used whenever fan coils are used in downflow applications.
4. Downflow/Horizontal Conversion Gasket Kit
This kit provides the proper gasketing of units when applied in either a downflow or horizontal application.
REQUIRED USE: Fan coils in either downflow or horizontal applications.
5. Horizontal Applications - Water Management Kit
This kit provides proper installation of fan coils under conditions of high static pressure and high relative humidity.
SUGGESTED USE: All fan coils.
6. Single Point Wiring Kit
The single point wiring kit acts as a jumper between L1 and L3 lugs, and between the L2 and L4 lugs. This allows the installer to run two
heavy-gauge, high-voltage wires into the fan coil rather than 4 light-gauge, high-voltage wires.
SUGGESTED USE: Fan coils with 15- and 20-kW fused heaters only.
7. Filter Kit (12 pack)
The kit consists of 12 fan coil framed filters. These filters collect large dust particles from the return air entering the fan coil and prevents them
from collecting on the coil. This process helps to keep the coil clean, which increases heat transfer and, in turn, the efficiency of the system.
SUGGESTED USE: To replace filters in fan coils.
REQUIRED USE: All units unless a filter grille is used.
8. Fan Coil Filter Cabinet
This cabinet is mounted to the fan coil on the return air end and designed to slip over the outer fan coil casing. The cabinets are insulated using the
same insulation as production fan coils. They are designed for the removal of particulates from indoor air using FILXXFNC00(14, 17, 21, 24)
media filter cartridges. These fan coil media filter cartridge kits are designed for the removal of particles from indoor air. The cartridge is installed
in the return air duct next to the air handler or further upstream.
SUGGESTED USE: All fan coils.
9. PVC Condensate Drain Trap Kit
This kit consists of 50 PVC condensate traps. Each trap is pre-formed and ready for field installation. This deep trap helps the system make and
hold proper condensate flow even during blower initiation.
SUGGESTED USE: All fan coils.
10. TXV Kit
These kits are designed to add TXVs to piston fan coils or convert R-410A fan coils to R-22 TXVs.
11. Door Gasket Kit
This kit consists of specific adhesive-backed foam strips which are applied to the unit door and frame, limiting air leakage.
12. Accessory Quick Connect Kit
This kit enables the installer to easily connect a 230V IAQ accessory (air purifier, electronic air cleaner, UV light, etc.) kit to a fan coil unit,
eliminating the need to run a separate power supply to the accessory. Use of this kit may eliminate the requirement for a licensed electrician to
complete the job (check local codes).
