Carrier AquaSnap 30MPA050 Installation Instructions Manual

Contents

4INSTALLATIONLocation — Do not store units in an area exposed to weath-er because of sensitive control mechanisms and electronicdevices. Locate unit indoors.When considering location, consult National ElectricalCode (NEC) and local code requirements. Allow sufficientspace for wiring, piping, and service. Install the unit in an areawhere it will not be exposed to ambient temperatures below50°F (10°C).Allow 36 in. (914 mm) in front of the unit for the controlbox access door. Additional clearance may be required per lo-cal codes. Prior to installation determine which direction thecompressor will be removed, and leave 3 to 4 ft (914 to1219 mm) clearance for removal.On all units leave 3 ft (0.9 m) of clearance opposite the con-trol box end to make water/brine connections to the evaporator,accessing the TXV (thermostatic expansion valve) or EXV(electronic expansion valve), fluid thermistors, and proof offlow switch.For units without water manifold option, leave 2 ft(610 mm) on the left facing control box side for makingrefrigeration connections (30MPA) or leave 2 ft (610 mm)on one side for making fluid connections (30MPW) tocondenser. See Fig. 6-17.The floor must be strong enough to support the unit operat-ing weight (see Tables 1-4, Fig. 6-14, and Fig. 18). If necessary,add a supporting structure (steel beams or reinforced concreteslabs) to the floor to transfer weight to the nearest beams.Additional weight of factory-installed sound enclosure op-tion is 75 lb (34 kg). Additional operating weight of 30MPAwater manifold option is 218 lb (99 kg). Additional operatingweight of 30MPW water manifold option is 436 lb (198 kg).Multiple chiller applications using the Vibration IsolatorSprings Accessory Kit should be set on a mounting frame,which should then be installed on the isolator springs. I-beamor square metal tubing are acceptable materials for the mount-ing frame. Each chiller MUST be supported in the center (un-der the heat exchangers) by the mounting frame, however iso-lators are only necessary at the four corners of each unit. UseFig. 18, for the corner weights of each when supported in fourlocations.For standalone units (chillers which are not connected viacommon water piping), 30MP 015-045 must be supported atthe four corner locations shown in Fig. 18. 30MP 050-071must be supported at the six locations shown in Fig. 19.WARNINGIf a 30MPE electrical distribution panel is purchased, it iscrucial that each individual 30MP chiller be placed in theappropriate position relative to its corresponding 30MPEelectrical distribution panel. Failure to do so could causepersonal injury or death. Please consult the 30MPE Electri-cal Distribution Panel Installation Instructions for moredetails.CAUTIONBe sure interconnecting piping and electrical conduitsare suspended freely, and are not in contact with anyadjacent walls. Be sure unit capillaries are not rubbingagainst anything. Damage to the unit or walls may result.
