Carrier Performance 50VG-K Installation Instructions Manual

50VG-K: Installation InstructionsManufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.8Only trained, qualified crane operators and ground support staff shouldhandle 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 othersafety precautions that might apply.Training for operators of the lifting equipment should include, but not belimited to, the following:1. Application of the lifter to the load, and adjustment of the lifts toadapt 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, suchas balance, temperature, etc.Follow all applicable safety codes. Wear safety shoes and work gloves.A07925Fig. 6 – Unit Leveling TolerancesInspectionPrior to initial use, and at monthly intervals, all rigging shackles, clevispins, and straps should be visually inspected for any damage, evidenceof wear, structural deformation, or cracks. Particular attention should bepaid to excessive wear at hoist hooking points and load support areas.Materials showing any kind of wear in these areas must not be used andshould be discarded.1. Leave top shipping skid on the unit for use as a spreader bar toprevent the rigging straps from damaging the unit. If the skid is notavailable, use a spreader bar of sufficient length to protect the unitfrom damage.Rigging/Lifting of Unit (See Fig. 5)Lifting holes are provided in base rails as shown.1. Attach shackles, clevis pins, and straps to the base rails of the unit.Be sure materials are rated to hold the weight of the unit (SeeFig. 5).2. Attach a clevis of sufficient strength in the middle of the straps.Adjust the clevis location to ensure unit is lifted level with theground.After the unit is placed on the roof curb or mounting pad, remove the topskid.A07926Fig. 7 – Slab Mounting DetailStep 6 – Connect Condensate DrainNOTE: When installing condensate drain connection be sure to complywith local codes and restrictions.This model disposes of condensate water through a 3/4 in. NPT fittingwhich exits through the base on the evaporator coil access side. SeeFig. 2 and Fig. 3 for location.Condensate water can be drained directly onto the roof in rooftopinstallations (where permitted) or onto a gravel apron in ground levelinstallations. Install a field-supplied 2-in. (51 mm) condensate trap atend of condensate connection to ensure proper drainage. Make sure thatthe outlet of the trap is at least 1 in. (25 mm) lower than the drain pancondensate connection to prevent the pan from overflowing (See Fig. 8).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. copperpipe (all field-supplied) at the outlet end of the 2-in. (51 mm) trap. Donot undersize the tube. Pitch the drain tube downward at a slope of atleast 1-in. (25 mm) for every 10 ft (3.1 m) of horizontal run. Be sure tocheck the drain tube for leaks. Prime trap at the beginning of the coolingseason start-up.WARNING!UNIT FALLING HAZARDFailure to follow this warning could result in personal injury or death.Never stand beneath rigged units or lift over people.WARNING!PROPERTY DAMAGE HAZARDFailure to follow this warning could result in personal injury.When straps are taut, the clevis should be a minimum of 36 in. (914mm) above the unit top cover.ABCMAXIMUM ALLOWABLEDIFFERENCE in.
