1.
PRESSURE CHECK
When the valve package is factory installed, the unit is shipped with the coil and
associated piping/valve package pressurized. Use the air valve to release the pressure.
Should there be no pressure, inspect the unit for possible shipping damage. The unit
must be pressure tested again prior to installation.
2.
MOUNTING
This unit is free standing. It MUST be leveled when installed. When leveling legs
are supplied (optional), these are located under the unit’s bottom panel. Turn the bolts
as required until the unit is perfectly leveled to ensure proper condensate drainage.
3.
PIPING
3.1
All piping leading to the unit must be adequately supported to prevent excessive stress
on the unit’s piping. However, sufficient free movement is required for thermal
expansion/contraction.
3.2
Threaded connections must not be over tightened.
3.3
Sweat connections must not be overheated. Use solder (95/5) with a melting
temperature below 600
o
F.
3.4
When the valve package is supplied separately for field installation, carefully follow
the schematic piping diagram and installation instructions provided with the package.
3.5
The inlet (supply), outlet (return) and condensate (drain) points are clearly marked on
the unit’s piping. Depending upon the filed piping layout, the connecting inlet, outlet
and condensate piping could be at the right or left side of the unit. Follow the
Engineer’s pipe layout drawing while routing the supply, return and drain lines to and
from the unit.
3.6
All pipes and fittings outside the unit’s enclosure must be properly insulated as no
external condensate pan is provided with the standard unit.
