that the unit is installed level in order to
handle condensate drainage. The
condensate drain should be trapped, and the
drain line sloped toward the drain at a 1/4"
per foot slope. Ensure that no screws
puncture the drain pan.
The Airmax Accessory slab coil must be
installed in a vertical position (horizontal
airflow through the coil) or condensate
drainage problems will result. It is acceptable
use a field supplied
“A” type evaporative coil .
Some building codes call for a secondary
drain pan under the entire unit. Check local
codes for more information. Any installation
that has the potential of property damage
due to condensate should have a secondary
drain pan installed. If the unit is installed in a
high heat and/or humidity location, extra
insulation around the unit casing may be
required to prevent excessive condensate
from forming on the outer surface of the
casing. Install the unit so that there is
adequate clearance on all sides for service
and for piping runs.
When connecting the refrigerant lines to the
cooling coil, installations instructions with the
coil should be followed. It is also
recommended, but not mandatory that you
install a site glass and filter/drier at the
condensing unit, as well as both high and low
side access ports. This is useful for both the
system setup, and for future trouble shooting.
Care must be taken when mounting the
Airmax Accessory slab coil directly to the
side of a Airmax vertical airflow fan coil. This
is acceptable only on the side of the fan coil
opposite the fan motor end. If mounting the
coil on the side where the end of the fan
motor is located use a short spacer fitting to
move the coil face away from the back of the
motor housing. Failure to do so will cause
excessive or non-uniform velocity across the
coil surface and may cause condensate carry
over into the fan coil cabinet.
condensing unit
Locate the outdoor unit in a suitable location,
as close as possible to the fan coil. Maintain
the clearances recommended by the
condensing unit manufacturer’s installation
manual to ensure proper airflow. The outdoor
unit must be installed in a level, properly
supported location. A sight glass and liquid
line filter/drier is recommended but not
mandatory.
freezestat and TX valve
MaxAir
™ accessory DX evaporator coils
come with an anti-ice control frost thermostat
(see appropriate wiring diagram) installed on
the suction line. Ensure that the TXV bulb
and the frost thermostat control are fastened
securely and are well insulated.
DO
NOT use a self-tightening clamp on the frost
thermostat as excessive tightening may
damage the thermostat.
The remote sensing bulb for the TX valve
should be located on a clean,
horizontal
section of the suction line. It should be
mounted on the top half of the pipe in the 2
o’clock or 10 o’clock position.
