2EXPLOSION HAZARDFailure to follow this warning couldresult in death, serious personal injury,and/or property damage.Never use air or gases containingoxygen for leak testing or operatingrefrigerant compressors. Pressurizedmixtures of air or gases containingoxygen can lead to an explosion.! WARNINGCUT HAZARDFailure to follow this caution may result in personal injury.Sheet metal parts may have sharp edges or burrs. Use care andwear appropriate protective clothing and gloves whenhandling parts.CAUTION!121. GZ Series Water--To Air Split System2. Packet containing: Installation, Owner’s Manual, WarrantyCertificate and badges A14176Fig. 1 -- Standard PackageINSTALLATION RECOMMENDATIONSThe Water--to--Air Heat Pumps are designed to operate withentering fluid temperature between 20_F to 90_F in the heatingmode and between 30_F to 120_F in the cooling mode.NOTE: 50_F minimum Entering Water Temperature (EWT) isrecommended for well water applications with sufficient waterflow to prevent freezing. Antifreeze solution is required for allclosed loop applications. Geothermal applications should havesufficient antifreeze solution to protect against extreme conditionsand equipment failure. Frozen water coils are not covered underwarranty. Other equivalent methods of temperature control areacceptable.Check Equipment and Job SiteMoving and StorageIf the equipment is not needed for immediate installation upon itsarrival at the job site, it should be left in its shipping carton andstored in a clean, dry area. Units must only be stored or moved inthe normal upright position as indicated by the “UP” arrows oneach carton at all times.EQUIPMENT DAMAGE HAZARDFailure to follow this caution may result in equipment damage.If unit stacking is required for storage, stack units as follows:Do not stack units larger than 6 tons!Vertical units: less than 6 tons, no more than two high.Horizontals units: less than 6 tons, no more than three high.CAUTION!Inspect EquipmentBe certain to inspect all cartons or crates on each unit as received atthe job site before signing the freight bill. Verify that all items havebeen received and that there are no visible damages; note anyshortages or damages on all copies of the freight bill. In the eventof damage or shortage, remember that the purchaser is responsiblefor filing the necessary claims with the carrier. Concealed damagesnot discovered until after removing the units from the packagingmust be reported to the carrier within 24 hours of receipt.Location / ClearanceTo maximize system performance, efficiency and reliability, and tominimize installation costs, it is always best to keep the refrigerantlines as short as possible. Every effort should be made to locate theair handler and the condensing section as close as possible to eachother.Serviceability should be a consideration and units should be placedso that installer and service technicians can access the service sideof the unit with ease. The electrical box side of unit shouldmaintain a clearance of 24” (609.6mm) minimum.NOTE: Consider access to service parts before setting in place.Condensing Section LocationLocate the condensing section in an area that provides sufficientroom to make water and electrical connections and allows easyremoval of the access panels in order for service personnel toperform maintenance or repair.The condensing section is designed primarily for Indoor use.However, if installed in outside location where it could besubjected to freezing conditions the following conditions should beimplemented:S Freeze protection should be employed.S Freeze stat -- To monitor water temp and start the looppump if there is danger of freezing, even if there is noheating call.S Pump timer/starter or similar deviceS Water lines entering and leaving the unit should be properlyinsulated prior to ground contact.The GZ unit should be mounted level on a vibration absorbing padslightly larger than the base to minimize vibration transmission tothe building structure. It is not necessary to anchor the unit to thefloor (see Fig. 2).A14177Fig. 2 -- Vibration Pad LocationThe vast majority of geothermal units are installed indoors and thecondenser pads on the market are typically not designed for indoorequipment. Table 1 lists recommended pads (sold separately)designed for indoor packaged equipment. ACMP pads are madeof 3/4” thick high density SBR recycled rubber, which provides ahigh degree of vibration and sound absorption for compressorbearing units installed indoors. These pads may be trimmed asneeded.Table 1 – Recommended Mounting PadsUnit Size Mounting Pad Pad DimensionsGZ024 ACMP2436 24” x 36”GZ036 ACMP2436 24” x 36”GZ048 ACMP2436 24” x 36”GZ060 ACMP2836 28” x 36”GZ072 ACMP2836 28” x 36”Fan Coil or Furnace LocationRefer to the Fan Coil or Furnace Installation Manual for completeDetails on indoor locations and clearances.
