The factory charge is sufficient for 25 feet of standard liquid line. For longer or shorter liquid line
lengths, adjust the charge as follows:
1/4" Line +/- 0.3 oz. Per foot
5/16" Line +/- 0.4 oz. Per foot
3/8" Line +/- 0.6 oz. Per foot
1/2" Line +/- 1.2 oz. Per foot
Vertical Separation between Indoor and Outdoor Units
Maximum allowable vertical separations between indoor and outdoor units are illustrated in Figure
3-A and Figure 3-B. It's 70' when the indoor unit is below the outdoor unit (Figure 3-A), and 50' when
the indoor unit is above the outdoor unit (Figure 3-B).
To ensure good oil return to the compressor when the indoor unit is below the outdoor unit, suction
line oil trap should be used as illustrated in Figure 3-A.
Tubing Connections
! CAUTION - Use extreme caution in removing the caps from the suction and liquid line fittings, as
there is pressure present. A fitting is on the liquid line to remove pressure.
! CAUTION - Condensing units are charged with refrigerant. Condensing unit liquid and suction
valves are closed to contain the charge within the unit. Do not force the valve stem against the retaining
ring. If the valve stem is backed out past the retaining ring, system pressure could force the valve stem
out of the valve body and possibly cause personal injury.
! CAUTION - The piston is in the accessory bag. Don't forget to take it out and put into the indoor
liquid pipe orifice.
Instructions on the field tubing connections and valve opening procedure are as follow:
Refrigerant Line Sizing
Check the following table (Table 2 ) for correct suction and liquid line sizes for any combination of
the unit size and the maximum refrigerant line length.

- Do not allow the vapor line and liquid line to touch together this would cause an undesirable heat transfer resulting in capacity loss and increased power consumption 8
- Figure 3 8
- Line insulation suction line requires insulation in order to prevent condensation from forming on the piping and to prevent heat gain caused by surrounding air generally 3 8 wall thickness of armflex or equivalent is satisfactory in severe application hot high humidity areas greater thickness may be required apply the line insulation by sliding it on the sealed tuing before cutting and making connections 8
- Liquid line does not necessarily need insulation however if they are exposed to high ambient temperatures i e kitchen boiler rooms hot attics rooftop surface then they should be insulated make sure to use the proper size tubing for the liquid line to prevent liquid refrigerant flashing to a vapor within the liquid line 8
