Charging in Cooling above
55°F OD Ambient
If servicing the equipment requires system evacuation,
then re-charge the system to the weight specified on
the nameplate Verify the system subcooling using the
Subcooling Charging Table and, if necessary, adjust
the charge using the procedure below
1 For best results — the indoor temperature should
be kept between 70°F to 80°F Add system heat if
needed
2 Whenever charge is removed or added, the system
must be operated for a minimum of 20 minutes to
stabilize before accurate measurements can be
made
3 Measure Liquid Line Temperature and Refrigerant
Pressure at service valved in the compressor
compartment
4 Locate your liquid line temperature in the left
column of the table, and the intersecting liquid line
pressure under the subcool value column, Add
refrigerant to raise the pressure to match the table,
or remove refrigerant to lower the pressure Again,
wait 20 minutes for the system conditions to
stabilize before adjusting charge again
NNoottee:: System char e shall never be more than 110% or
less than 90% of nameplate char e. If specified
subcoolin cannot be achieved within those
char e bounds, contact your Field Service
Representative.

1 The Subcool Charging Method in cooling is NOT
recommended below 55°F outdoor ambient
2 The only recommended method of charging at
outdoor ambients below 55°F, is to weigh in the
charge in the heating mode
3 Use Nameplate charge
4 Check liquid line temperature and pressure (at the
OD valves) to obtain a minimum of the subcooling
shown in the subcooling table
5 Add charge if the minimum subcooling as shown in
the table is not obtained with the nameplate charge
6 It is important to return in the spring or summer to
accurately charge the system in the cooling mode
at outdoor ambients above 55°F

Review Location and Recommendation Information
HHoorriizzoonnttaall AAiirrffllooww UUnniittss
1 Location of the unit must allow service clearance
around it to ensure adequate serviceability,
maximum capacity, and peak operating efficiency
2 These units are designed for outdoor installation
They may be installed directly on a slab, wood
flooring, or on Class A, B, or C roof covering
material The discharge air from the condenser fans
must be unrestricted for a minimum of 3 feet above
the unit
3 Check the handling facilities to ensure the safety of
personnel and the unit(s)
4 The unit must be mounted level for proper drainage
of water through the drain holes in the base pan
5 The unit should not be exposed to direct roof water
runoff
6 Flexible duct connectors must be of a flame
retardant material All duct work outside of the
structure must be insulated and weatherproofed in
accordance with local codes
7 Holes through exterior walls or roof must be sealed
in accordance with local codes
8 All fabricated outdoor ducts should be as short as
possible
CClleeaarraanncceess
1 The recommended clearances for single-unit
installations are illustrated in “Determine Unit
Clearances,” p 7
2 Any reduction of the unit clearances indicated in
these figures may result in condenser coil
starvation or the recirculation of warm condenser
air Actual clearances, which appear to be
inadequate should be reviewed with a local
engineer
3 See the unit’s nameplate for the absolute minimum
clearance between the unit and any combustible
surfaces
DDoowwnn AAiirrffllooww UUnniittss
1 Location of the unit must allow service clearance
around it to ensure adequate serviceability,
maximum capacity, and peak operating efficiency
2 Refer to the Installation section for instruction on
converting the supply and return airflow covers to
down airflow
3 The field assembled Roof Mounting Curb
(BAYCURB050A or BAYCURB051A) or a field
fabricated curb should be in place before the unit is
hoisted to the roof top
The Roof Mounting Curb (frame) must be installed
on a flat, level section of the roof (maximum of 1/4"
per foot pitch) and provide a level mounting surface
for the unit Also, be sure to provide sufficient
height above the roof to prevent water from
entering the unit
