ALL phases of this installation must comply with NATIONAL, STATE AND LOCAL CODES.
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.
The manufacturer recommends installing only approved matched indoor and outdoor systems. All of the manufacture's split
systems are A.H.R.I. rated only with TXV/EEV indoor 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.

5.4 Refrigerant Line Insulation Important: The Vapor Line must always be Vapor Line Liquid Line insulated. DO NOT allow the Liquid Line and Insulation Vapor Line to come in direct (metal to metal) contact. 5.5 Reuse Existing Refrigerant Lines CAUTION If using existing refrigerant lines make certain that all joints are brazed, not soldered. -

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. -

STEP 2 - Observe the micron gauge. Evacuation is complete if the micron gauge does not rise above 500 microns in one (1) minute. 1 MIN. Once evacuation is complete blank off the vacuum pump and micron gauge, and close the valves on the manifold gauge set. - Page 11 11.2 Low Voltage Hook-up Diagrams With TEM 3, 4, 6, 8 With TAM 4, 7, 9 Outdoor Outdoor Thermostat Air Handler Thermostat Air Handler Unit Unit 24 VAC HOT 24 VAC HOT 24 VAC 24 VAC Common Common Blue Blue COOL/HEAT COOL/HEAT 1st STAGE...

STEP 3 - Turn on disconnect(s) to apply power to the indoor and outdoor units. STEP 4 - Wait one (1) hour before starting the unit if compressor crankcase heater acces- sory is used and the Outdoor Ambient is below 60 MIN. - Page 14 14.2 Subcooling Charging in Cooling (Above 55º F Outdoor Temp.) STEP 1 - Use the refrigerant line total length and lift measurements from Section 5.3. Total Line Length = __________ Ft. Vertical Change (Lift) = __________ Ft. LIFT STEP 2 - Determine the final subcooling value using total Line Length and Lift measured in STEP 1 and the charts below. 018 Units 024 Units SUBCOOL CHARGING CHART CORRECTIONS TABLE (FOR LINE LENGTH AND RISE)
- Page 15 STEP 3 - Stabilize the system by operating for a minimum of 20 minutes. At startup, or whenever charge is removed or 20 MIN. added, the system must be operated for a mini- mum of 20 minutes to stabilize before accurate measurements can be made.
- Page 16 STEP 6 - Adjust refrigerant level to attain proper gage pressure. Add refrigerant if the Liquid Gage Pressure is lower than the chart value. 1. Connect gages to refrigerant bottle and unit as illustrated. 2. Purge all hoses. 3. Open bottle. 4.
