IV. PROVIDE CLEARANCES
The required minimum operating and service clearances are shown
in Fig. 6 and 7. Adequate combustion, ventilation, and condenser
air must be provided, in accordance with section 5.3, Air for
Combustion and Ventilation, of the National Fuel Gas Code ANSI
(American National Standards Institute) Z223.1 (in Canada, sec-
tions 7.2, 7.3 or 7.4 or Can/CGA (Canadian Gas Association)
B149 Installation Codes), or applicable provisions of local build-
ing code.
CAUTION: Do not restrict condenser airflow. An air
restriction at either the outdoor-air inlet or the fan
discharge can be detrimental to compressor life.
The condenser pulls air through the condenser coil and discharges
it through the top cover. Be sure that the fan discharge does not
recirculate to the condenser coil. Do not locate the unit in either a
corner or under an overhead obstruction. The minimum clearance
under a partial overhang (such as a normal house overhang) is
48-in. above the unit top. The maximum horizontal extension of a
partial overhang must not exceed 48 inches.
Do not place the unit where water, ice, or snow from an overhang
or roof will damage or flood the unit. Do not install the unit on
carpeting, tile, or other combustible materials. The unit may be
installed on wood flooring or on Class A, B, or C roof covering
materials.
V. RIG AND PLACE UNIT
Rigging and handling of this equipment can be hazardous for many
reasons due to the installation location (roofs, elevated structures,
etc.).
Only trained, qualified crane operators and ground support staff
should handle and install this equipment.
When working with this equipment, observe precautions in the
literature, on tags, stickers and labels attached to the equipment,
and any other safety precautions that might apply.
Training for operations of the lifting equipment should include, but
NOT be limited to the following:
1. Application of the lifter to the load and adjustment of the
lifts, if any, that adapts it to various sizes or kinds of loads.
2. Instruction in any special operation or precaution.
3. Condition of the load itself, required for operation of the
lifting kit, such as balance, temperature, etc.
Follow all applicable safety codes. Wear safety shoes and work
gloves.
WARNING:
Never exceed 200 lbs. per bracket lifting force.
Accessory lifting kit is only to be used with Small
Packaged units which have a composite base pan with
molded hand holds.
Never stand beneath rigged units or lift over people.
Lifting point should be directly over the center of gravity
for the unit.
A dropped unit could cause serious injury or death.
INSPECTION — Prior to initial use, and at monthly intervals, all
rigging brackets and straps should be visually inspected for any
damage, evidence of wear, structural deformation, or cracks.
Particular attention should be paid to excessive wear at hoist
hooking points and load support areas. Brackets or straps showing
any kind of wear in these areas must not be used and should be
discarded.
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
handholds in the composite pan.
3. Tighten the ratchet strap until tight. Lifting brackets should
be secure in the handholds.
4. Attach the clevis or hook of sufficient strength to hole in the
lifting bracket as shown in Fig. 8.
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.
VI. CONNECT CONDENSATE DRAIN
NOTE: When installing condensate drain connection be sure to
comply with local codes and restrictions.
The 583B units dispose of condensate water through a 3/4 in. NPT
fitting which exits through the compressor access panel. See Fig.
6 and 7 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 drain pan
condensate connection to prevent the pan from overflowing. See
Fig. 9. Prime the trap with water. When using a gravel apron, make
sure it slopes away from the unit.
