Beforeunit start-up, read all manuals and become familiar with theunit and its operation. Thoroughly check out the system beforeoperation. Complete the inspections and instructions listedbelow to prepare a unit for installation. See Tables 1 and 2 forunit physical data.HORIZONTAL UNITS (50HQL) — Horizontal units aredesigned for indoor installation only. Be sure to allow ade-quate space around the unit for servicing. See Fig. 1A and 1Bfor overall unit dimensions. Refer to Fig. 2 for an example ofa typical horizontal installation.VERTICAL UNITS (50VQL) — Vertical units are designedfor indoor installation only. While vertical units are typicallyinstalled in a floor-level closet or a small mechanical room, theunit access guidelines for these units are very similar to thosedescribed for horizontal units. Refer to Fig. 3 for an example ofa typical vertical installation. See Fig. 4A-4C for overall unitdimensions.Step 2 — Check Unit — Upon receipt of shipment atthe jobsite, carefully check the shipment against the bill oflading. Make sure all units have been received. Inspect the car-ton or crating of each unit, and inspect each unit for damage.Ensure the shipping company makes proper notation of anyshortages or damage on all copies of the freight bill. Concealeddamage not discovered during unloading must be reported tothe shipping company within 15 days of receipt of shipment.NOTE: It is the responsibility of the purchaser to file allnecessary claims with the shipping company.1. Verify unit is correct model for entering water tempera-ture of job.2. Be sure that the location chosen for unit installation pro-vides ambient temperatures maintained above freezing.Well water applications are especially susceptible tofreezing.3. Be sure the installation location is isolated from sleepingareas, private offices and other acoustically sensitivespaces.NOTE: A sound control accessory package may be usedto help eliminate sound in sensitive spaces.4. Check local codes to be sure a secondary drain pan is notrequired under the unit.5. Be sure unit is mounted at a height sufficient to providean adequate slope of the condensate lines. If an appropri-ate slope cannot be achieved, a field-supplied condensatepump may be required.6. Provide sufficient space for duct connection.7. Provide adequate clearance for filter replacement anddrain pan cleaning. Do not allow piping, conduit, etc. toblock filter access.8. Provide sufficient access to allow maintenance andservicing of the fan and fan motor, compressor and coils.Removal of the entire unit from the closet should not benecessary.9. Provide an unobstructed path to the unit within the closetor mechanical room. Space should be sufficient to allowremoval of unit if necessary.10. Provide ready access to water valves and fittings, andscrewdriver access to unit side panels, discharge collar,and all electrical connections.11. Where access to side panels is limited, pre-removal of thecontrol box side mounting screws may be necessary forfuture servicing.STORAGE — If the equipment is not needed for immediateinstallation upon its arrival at the jobsite, it should be left in itsshipping carton and stored in a clean, dry area of the buildingor in a warehouse. Units must be stored in an upright positionat all times. If carton stacking is necessary, stack units a maxi-mum of 3 high. Do not remove any equipment from its ship-ping package until it is needed for installation.Electrical shock can cause personal injury or death. Beforeinstalling or servicing system, always turn off main powerto system. There may be more than one disconnect switch.Turn off accessory heater power if applicable.IMPORTANT: The installation of water source heat pumpunits and all associated components, parts, and accessorieswhich make up the installation shall be in accordance withthe regulations of ALL authorities having jurisdiction andMUST conform to all applicable codes. It is the responsi-bility of the installing contractor to determine and complywith ALL applicable codes and regulations.To avoid equipment damage, do not use these units as asource of heating or cooling during the constructionprocess. The mechanical components and filters used inthese units quickly becomes clogged with constructiondirt and debris which may cause system damage.
