IMPORTANT - This Document is customer property and is to remain with this unit. Please return to service informa-
tion pack upon completion of work.
These instructions do not cover all variations in systems or provide for every possible contingency to be met in connection with
the installation. Should further information be desired or should particular problems arise which are not covered sufficiently for the
purchaser's purposes, the matter should be referred to your installing dealer or local distributor.
Note: The manufacturer recommends installing only approved matched indoor and outdoor systems. Some of the benefits of
installing approved matched indoor and outdoor split systems are maximum efficiency, optimum performance and the best overall
system reliability.

STEP 5 - Replace the pressure tap valve cores after the service valves have cooled. Section 8. Refrigerant Line Leak Check 8.1 Check For Leaks STEP 1 - Pressurize the refrigerant lines and 150 PSIG evaporator coil to 150 PSIG using dry nitrogen. STEP 2 - Check for leaks by using a soapy solu- tion or bubbles at each brazed location. -

Using a digital psychrometer, measure the return air wet-bulb temperature at the unit just before the coil. Also measure the outdoor dry-bulb tem- perature. Use these temperatures to locate the target superheat on the charging table. Do not attempt to charge the system if these conditions fall outside of this charging table.
