DRAIN PAN
Standard drain pans are externally insulated, single wall
galvanized steel and can be equipped with a secondary
drain connection. The HL drain pan is easily removable
for cleaning. See illustration below. Auxiliary drip pan
to catch condensed moisture from valves and piping
must be sloped toward the drain pan.
The condensate drain pan can be removed without re-
quiring common hand tools. The drain pan is secured
to the unit by four sheet metal tabs that slide into four
respective slots on the drain pan.
Prior to removing the drain pan, make sure all
accessories and field connections have been
appropriately disconnected from the drain pan.
The drain pan can be removed in three steps. First,
push the drain pan engagement lever to unlock the
drain pan from the coil. Next, while continuing to
push the lever, support the weight of the drain pan
and slide the drain pan towards the drain connection.
After the drain pan slides approximately 1.5 inches,
it will be completely disengaged from the coil.
Lastly, support the weight of the drain pan and
safely lower the drain pan for servicing. Reinstall
prior to unit startup.
COILS
All fan coils are available in 2 or 4 pipe configurations.
Heating coils are available in reheat or preheat position.
Heating and cooling coils are available with right, left
or opposite side connections.
Verify that the proper types of service are actually
provided to the unit. On units with steam heating
coils, the maximum steam pressure applied to the unit
should never exceed 15 PSIG. The drain piping and
steam trap should be sized and routed to allow for
proper condensate flow. The electrical service to the
unit should be compared to the unit nameplate to verify
compatibility. The routing and sizing of all piping, and
the type and sizing of all wiring and other electrical
components such as circuit breakers, disconnect
switches, etc., should be determined by the individual
job requirements and should not be based on the size
and/or type of connection provided on the equipment.
All installations should be made in compliance with all
governing codes and ordinances. Compliance with all
codes is the responsibility of the installing contractor.
