c. Open the vacuum gauge valve (D) and evacuate to 250

microns or less. If the system cannot be evacuated,

replace the vacuum pump equipment and repeat steps

(a) through (c) again. Otherwise, the pump and gauge

are operating properly and you can continue on to the

next step; evacuating the system. Before proceeding,

be sure to close the valve to the vacuum gauge to avoid

“pegging the meter” and potential gauge damage.

Step 2. Evacuate Lines And Indoor Coil.

a. Open the high and low side valves (B & A) on the gauge

manifold. NOTE: Only open the valve (E) on the gauge

manifold leading to the cylinder, not the valve on the

charging cylinder (F).

b. Evacuate the system to about 29 inches Hg as mea-

sured by the low side gauge.

c. Open the valve (D) to the vacuum gauge. Evacuate

until the gauge reads 250 microns or less.

d. Close the valve to the vacuum pump (C). Wait five

minutes, then check the pressure on the vacuum

gauge:

1. If the pressure is not more than 1500 microns, the

system is leak-free and properly evacuated. Pro-

ceed to step (e).

2. If the pressure rises, but holds at about 5000 mi-

crons, moisture and noncondensibles are still present.

Open the valve to the vacuum pump (E), and go back

to step (c).

3. If the pressure rises above 5000 microns, a leak is

present. Go back to “Leak Testing” section on page

e. Close the valve to the vacuum gauge.

f. Close the valve to the vacuum pump. Shut off the

pump.

Electrical Connections

WARNING

To avoid personal injury, shock, or death,

open the electrical disconnect switch

before electrically connecting the unit.

Wiring must conform with National

Electrical Code (NEC) or Canadian

Electrical Code (CEC) and all local codes.

The wiring diagram for this unit can be found on the control

box door. Refer to Figure 4 for field wiring connections.

WARNING

To avoid the risk of fire or equipment

damage, use only copper conductors.

WARNING

Undersized wires could cause poor equip-

ment performance, equipment damage, or

fire. Consult the National Electrical Code

or a qualified electrician for proper wire

size.

WARNING

To avoid electrical shock, injury, or death,

wiring to the unit must be properly

grounded.

Wire size is important to ensure proper unit operation. The

size must be sufficient to carry the minimum circuit ampacity

listed on the unit serial data plate. Amana recommends

sizing the wires to limit the voltage drop to a maximum of 2%

from the main breaker or fuse panel to the outdoor unit.

Consult the NEC, CEC, and all local codes to determine the
