Units are designed for indoor installation only. Be sure to al- low adequate space around the unit for servicing. See Fig. 1 and 2 for overall unit dimensions.
These units are not approved for outdoor installation and must be installed indoors in the structure being conditioned. Do not locate in areas where ambient conditions are not main- tained within 4.4 to 37.8 C.
CAUTION
To avoid equipment damage, do not use these units as a source of heating or cooling during the construction pro- cess. The mechanical components used in these units can quickly become clogged with construction dirt and debris which may cause system damage.
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.Verify unit is correct model for entering water tempera- ture of job.
2.Be sure the location chosen for unit installation provides ambient temperatures maintained above freezing. Well water applications are especially susceptible to freezing.
3.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.
4.Provide sufficient access to allow maintenance and servicing of the compressor and coils.
5.Provide an unobstructed path to the unit within the closet or mechanical room. Space should be sufficient to allow removal of unit if necessary.
6.Provide ready access to water valves and fittings, and screwdriver access to unit side panels.
7.Where access to side panels is limited,
STORAGE — If the equipment is not needed for immediate installation upon its arrival 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 maxi- mum of 3 cartons high. Do not remove any equipment from its shipping package until it is needed for installation.
