FIRE, EXPLOSION, ELECTRICAL SHOCK AND CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal injury, death or property damage.
A qualified installer or agency must use only factory--authorized kits or accessories when modifying this product.
INTRODUCTION
The 607C heat pump is fully self-- contained and designed for outdoor installation. (See Fig. 1) Standard units are shipped in a horizontal--discharge configuration for installation on a groundlevel slab. Standard units can be converted to downflow (vertical) discharge configurations for rooftop applications.
RECEIVING AND INSTALLATION
Step 1 — Check Equipment
Identify Unit
The unit model number and serial number are stamped on the unit identification plate. Check this information against shipping papers.
Inspect Shipment
Inspect for shipping damage while unit is still on shipping pallet. If unit appears to be damaged or is torn loose from its anchorage, have it examined by transportation inspectors before removal. Forward claim papers directly to transportation company. Manufacturer is not responsible for any damage incurred in transit. Check all items against shipping list. Immediately notify the nearest equipment distributor if any item is missing. To prevent loss or damage, leave all parts in original packages until installation.
Step 2 — Provide Unit Support
Roof Curb
Install accessory roof curb in accordance with instructions shipped with curb (See Fig. 5). Install insulation, cant strips, roofing, and flashing. Ductwork must be attached to curb.
IMPORTANT: The gasketing of the unit to the roof curb is critical for a watertight seal. Install gasketing material supplied with the roof curb. Improperly applied gasketing also can result in air leaks and poor unit performance.
Curb should be level to within 1/4 in. (6 mm) (See Fig. 6). This is necessary for unit drain to function properly. Refer to accessory roof curb installation instructions for additional information as required.
Slab Mount
Place the unit on a solid, level concrete pad that is a minimum of 4 in. (102 mm) thick with 2 in. (51 mm) above grade (See Fig. 7). The slab should extend approximately 2 in. (51 mm) beyond the casing on all 4 sides of the unit. Do not secure the unit to the slab except when required by local codes.
Ground Mount
The unit may be installed either on a slab or placed directly on the ground if local codes permit. Place the unit on level ground prepared with gravel for condensate discharge.
Step 3 — Provide Clearances
The required minimum service clearances are shown in Fig. 2 and
3. Adequate ventilation and outdoor air must be p rovided. The outdoor fan draws air through the outdoor coil and discharges it through the top fan grille. Be sure that the fan discharge does not recirculate to the outdoor 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. (1219 mm)above the unit top. The maximum horizontal extension of a partial overhang must not exceed 48 in. (1219 mm).
IMPORTANT: Do not restrict outdoor airflow. An air restriction at either the outdoor--air inlet or the fan discharge may be detrimental to compressor life.
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 or other combustible materials. Slab--mounted units should be at least 4 in. (102 mm) above the highest expected water and runoff levels. Do not use unit if it has been under water.
Step 4 — 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.
Trainingforoperators of thelifting equipment should include,but not be limited to, the following:
1. Application of the lifter to the load, and adjustment of the lifts to adapt to various sizes or kinds of loads.
2. Instruction in any special operation or precaution.
3. Condition of the load as it relates to operation of the lifting kit, such as balance, temperature, etc.
Follow all applicable safety codes. Wear safety shoes and work gloves.
INSPECTION
The lifting/rigging bracket is engineered and designed to be installed only on Small PackagedProducts.This bracket is to beused torig/lift a Small Packaged Product onto roofs or other elevated structures.
Prior to initial use, and at monthly intervals, all rigging brackets and straps should bevisually 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.

When designing and installing ductwork, consider the following:
1. All units should have field--supplied filters or accessory filter rack installed in the return--air side of the unit. Recommended sizes for filters are shown in Table 1.
2. Avoid abrupt duct size increases and reductions. Abrupt change in duct size adversely affects air performance.
IMPORTANT: Use flexible connectors between ductwork and unit to prevent transmission of vibration. Use suitable gaskets to ensure weather tight and airtight seal. When electric heat is installed, use fireproof 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. (610 mm) from electric heater element.
3. Size ductwork for cooling air quantity (cfm). The minimum air quantity for proper electric heater operation is listed in Table 2. Heater limit switches may trip at air quantities below those recommended.
4. Seal, insulate, and weatherproof all external ductwork. Seal, insulate and cover with a vapor barrier all ductwork passing through conditioned spaces. Follow latest Sheet Metal and Air Conditioning Contractors National Association (SMACNA) and Air Conditioning Contractors Association (ACCA) minimum installation standards for residential heating and air conditioning systems.
5. Secure all ducts to building structure. Flash, weatherproof, and vibration--isolate duct openings in wall or roof according to good construction practices.
