INSPECT UNIT — To prepare the unit for installation, com- plete the procedures listed below:

1.Compare the electrical data on the unit nameplate with ordering and shipping information to verify that the correct unit has been shipped.

2.Verify that the unit is the correct model for the entering water temperature of the job.

3.Do not remove the packaging until the unit is ready for installation.

4.Verify that the refrigerant tubing is free of kinks or dents, and that it does not touch other unit components.

5.Inspect all electrical connections. Be sure connections are clean and tight at the terminals.

6.Compressors are internally spring-mounted. Compressors equipped with external spring vibration isolators must have bolts loosened and shipping clamps removed.

7.Remove any blower support cardboard from inlet of the blower if present.

8.Locate and verify any accessory kit located in compressor section.

9.Remove any access panel screws that may be difficult to remove once unit is installed.

Step 3 — Location of Unit — The following guide- lines should be considered when choosing a location for WSHP. Refer to Fig. 1 and 2 for unit dimensional data:

•Provide sufficient space for water, electrical and duct connections

•Locate unit in an area that allows for easy access and removal of filter and access panels

•Allow enough space for service personnel to perform maintenance
