INSTALLATION
1. Position the lifting bracket assembly around the base of the
unit. Leave the top shipping skid on the unit to act as a
spreader bar. Be sure the strap does not twist.
2. Place each of the four (4) metal lifting brackets into the
rigging holds in the composite pan.
3. Tighten the ratchet strap unit tight. Lifting brackets should
be secure in the rigging holds.
4. Attach the clevis or hook of sufficient strength to hole in the
lifting bracket (see Fig. 6).
5. Attach safety straps directly to the field supplied rigging
straps or clevis clip. Do not attach the safety straps to the
lifting brackets.
6. Use the top of the unit as a spreader bar to prevent the
rigging straps from damaging the unit. If the wood top is not
available, use a spreader bar of sufficient length to not
damage the unit.
WARNING:
Lifting point should be directly over the
center of gravity for the unit.
VI.
CONNECT CONDENSATE DRAIN
NOTE: When installing condensate drain connection be sure to
comply with local codes and restrictions.
Models 701A and 702A dispose of condensate water through a 3/4
in. NPT fitting which exits through the base on the evaporator coil
access side. See Fig. 2 & 3 for location.
Condensate water can be drained directly onto the roof in rooftop
installations (where permitted) or onto a gravel apron in ground-
level installations. Install a field-supplied condensate trap at end of
condensate connection to ensure proper drainage. Make sure that
the outlet of the trap is at least 1 in. lower than the drainpan
condensate connection to prevent the pan from overflowing (see
Fig. 7). When using a gravel apron, make sure it slopes away from
the unit.
Connect a drain tube using a minimum of 3/4 -in. PVC or 3/4 -in.
copper pipe (all field-supplied) at the outlet end of the 2-in. trap.
Do not undersize the tube. Pitch the drain tube downward at a
slope of at least 1-in. for every 10 ft. of horizontal run. Be sure to
check the drain tube for leaks. Prime trap at the beginning of the
cooling season start-up.
VII.
INSTALL DUCT CONNECTIONS
The unit has duct flanges on the supply- and return-air openings on
the side and bottom of the unit. For downshot applications the
ductwork can be connected to the roof curb. See Fig. 2 & 3 for
connection sizes and locations.
IMPORTANT: Use flexible connectors between ductwork and
unit to prevent transmission of vibration. Use suitable gaskets to
ensure weathertight and airtight seal. When electric heat is
installed, use fire proof canvas (or similar heat resistant material)
connector between ductwork and unit discharge connection. If
flexible duct is used, insert a sheet metal sleeve inside duct. Heat
resistant duct connector (or sheet metal sleeve) must extend 24-in.
from the unit discharge connection flange into the ductwork.

CONFIGURING UNITS FOR DOWNFLOW (VERTI-
CAL) DISCHARGE
WARNING: Before performing service or maintenance
operations on the system, turn off main power to unit and
install lockout tag or electrical shock could result.
1. Open all electrical disconnects and install lockout tag before
starting any service work.
2. Remove return duct cover located on duct panel by breaking
four (4) connecting tabs with screwdriver and a hammer
(Fig. 8 & 9).
3. To remove supply duct cover, break front and right side
connecting tabs with a screwdriver and a hammer. Push
louver down to break rear and left side tabs (Fig. 8 & 9).
