Step 2 — Check Unit — Upon receipt of shipment at the jobsite, carefully check the shipment against the bill of lading. 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 any shortages or damage on all copies of the freight bill. Concealed damage not discovered during unloading must be reported to the shipping company within 15 days of receipt of shipment.
NOTE: It is the responsibility of the purchaser to file all necessary claims with the shipping company.
1.Be sure that the location chosen for unit installation pro- vides ambient temperatures maintained above freezing. Well water applications are especially susceptible to freezing.
2.Be sure the installation location is isolated from sleeping areas, private offices and other acoustically sensitive spaces.
NOTE: A sound control accessory package may be used to help eliminate sound in sensitive spaces.
3.Check local codes to be sure a secondary drain pan is not required under the unit.
4.Be sure unit is mounted at a height sufficient to provide an adequate slope of the condensate lines. If an appropri- ate slope cannot be achieved, a
5.Provide sufficient space for duct connection. Do not al- low the weight of the ductwork to rest on the unit.
6.Provide adequate clearance for filter replacement and drain pan cleaning. Do not allow piping, conduit, etc. to block filter access.
7.Provide sufficient access to allow maintenance and servicing of the fan and fan motor, compressor and coils. Removal of the entire unit from the closet should not be necessary.
8.Provide an unobstructed path to the unit within the closet or mechanical room. Space should be sufficient to allow removal of unit if necessary.
9.Provide ready access to water valves and fittings, and screwdriver access to unit side panels, discharge collar, and all electrical connections.
10.Where access to side panels is limited,
STORAGE — If the equipment is not needed immediately at the jobsite, it should be left in its shipping carton and stored in a clean, dry area of the building or in a warehouse. Units must be stored in an upright position at all times. If carton stacking is necessary, stack units a maximum of 3 high. Do not remove any equipment from its shipping package until it is needed for installation.
PROTECTION — Once the units are properly positioned on the jobsite, cover them with either a shipping carton, vinyl film, or an equivalent protective covering. Cap open ends of pipes stored on the jobsite. This precaution is especially important in areas where painting, plastering, or spraying of fireproof mate- rial, etc. is not yet complete. Foreign material that accumulates within the units can prevent proper
