Introduction
These Fan Coils are designed for installation flexibility. The units leave
the factory compliant with low leak requirements of less than 2% cabinet
leakage rate at 1.0 inches W.C. and 1.4% cabinet leakage rate at 0.5
inches W.C. when tested in accordance with ASHRAE 193 standard.
All these fan coils use a multi-tap ECM motor for efficiency. The units
have be designed for upflow, downflow (kit required), and horizontal
orientations, including manufactured and mobile home applications.
IMPORTANT: These units are designed specifically for Puron Advance
refrigerant and must be used only with Puron Advance refrigerant air
conditioners and heat pumps as shipped.
IMPORTANT: This unit MUST be installed in a location that is
LOWER than 600 meters above sea level. These units are available for
systems of 18,000 through 60,000 BTUh nominal cooling capacity. See
Product Data literature for all available accessory kits.
Electric Heat
IMPORTANT: Do not install electric heat in this unit. This unit is wired
for 115V operation and can not accommodate an accessory electric
heater.
Installation
Check Equipment
Unpack unit and move to final location. Remove carton taking care not
to damage unit.
NOTE: Shipping block(s) that support the blower housing during transit
will need to be removed (Fig. 1).

Fig. 1 – Remove Shipping Blocks
NOTE: If the door gasket is damaged or missing, the unit may not meet
the ASHRAE 193 standard for cabinet air leakage. See the Product Data
for this model or contact your supplier to order the gasket kit.
Inspect equipment for damage prior to installation. File claim with
shipping company if shipment is damaged or incomplete. Locate unit
rating plate which contains proper installation information. Check rating
plate to be sure unit matches job specifications.
Mount Unit
Unit can stand or lie on floor, or hang from ceiling or wall. Allow space
for wiring, piping, and servicing unit.
The indoor equipment and pipes shall be securely mounted and guarded
such that accidental rupture of equipment cannot occur from such events
as moving furniture or reconstruction activities. When a Fresh Air
Ventilator (HRV or ERV) is used, the air extraction opening from the
room shall be located equal to or below the top of the unit. For floor
mounted units, it shall be as low as practicable. The air extraction
openings shall be located in a sufficient distance, BUT NOT LESS
THAN 3ft 4in (3 m), from the air intake openings to prevent
re-circulation to the space. When a Fresh Air Ventilator (HRV or ERV) is
used, the lower edge of the air extraction opening where air is exhausted
from the room SHALL NOT be more than 4in (100 mm) above the floor.
IMPORTANT: When unit is installed over a finished ceiling and/or
living area, building codes may require a field-supplied secondary
condensate pan to be installed under the entire unit. Some localities may
allow as an alternative, the running of a separate, secondary condensate
line. Consult local codes for additional restrictions or precautions.
Nuisance sweating may occur if the unit is installed in a high humidity
environment with low airflow.
Upflow Installation
If return air is to be ducted through a floor, set unit on floor over opening
and use 1/8" to ¼" (3 to 6 mm) thick fireproof resilient gasket between
duct, unit, and floor.
Side return is a field option on slope coil models. Cut opening per
dimensions (Fig. 3). A field-supplied bottom closure is required.
WARNING
!
ELECTRICAL OPERATION HAZARD
Failure to maintain proper clearances could result in personal injury or
death.
Before installing or servicing unit, always turn off all power to unit.
There may be more than 1 disconnect switch. Turn off accessory heater

appropriate protective clothing, safety glasses and gloves when
handling parts.
CAUTION
!
HOT TUBE WARNING
Failure to follow this caution could result in personal injury and/or
property damage.
Refrigerant lines can reach or exceed 130 °F (54 °C). Avoid contact
with the vapor header or vapor line, especially in Heating Mode. Do not
service A2L refrigerant fan coils while these components are hot to
avoid risk of ignition source.
WARNING
!
EQUIPMENT DAMAGE, PROPERTY DAMAGE, OR
PERSONAL INJURY HAZARD
Do not install an electric heater in this unit. This unit is designed for a
supply voltage of 115VAC and can not be equipped with an internal
