5. Connect one end of the low voltage power cord to the tele-
phone jack socket in the detection unit and route the cord
and transparent drain tubing through the knockout on the
side of the unit enclosure (see Fig. 6).
6. Determine the mounting location of the pump assembly.
The pump assembly must always be above the level of
the detection unit. For best operation, it is recommended
that the pump assembly be mounted in a vertical position
with the flow arrow on the pump pointing up (see Fig. 7).
Do not exceed 10 ft. (3.0 m) maximum suction lift.
NOTE: in most applications, the pump will need to be mounted
outside of the high wall unit for proper orientation (i.e. above
drop ceiling).
7. Screw the bracket to the wall and attach the pump to the
bracket as shown in Fig. 4 and Fig. 5.

If the pump is not mounted in the vertical position, make sure that
plug on the pump is above the refrigerant tubing. This is required
to avoid water leaking onto the pump causing a short circuit. The
pump cannot be splashed nor located in a damp
environment.
8. Connect the other end of the low voltage power cord from
the detection unit to the telephone jack socket in the pump
assembly.
9. Cut the suction, transparent drain tubing after determining
where it will connect to the inlet side of the pump moun-
ted on the wall. Remove the cap on the pump inlet and
connect draining tubing.
10. Attach the remaining transparent tubing to the discharge
side of the pump. Keep the pipe vertical for at least 4 or 5
inches and do not exceed the 33 ft (10 m) limit or the
value shown in (B) of Table 3 and Table 4. In order to
avoid siphoning action and running the pump dry, al-
ways connect the discharge tube to the drain at a high-
er level than the pump itself (pump should be higher
than detection unit). Be sure the condensate is discharged
to a safe location where the presence of water does not
pose any safety or health hazards.
11. Install the transparent vent tube (provided) on top of the
detection unit. Route tube so it will stay vertical (see Fig.
6).
12. Wire the pump and the alarm circuit using the appropriate
wiring diagram listed in Table 2.
13. Prime the pump at start--up and after each maintenance op-
eration. To ensure proper operation, the suction pipe and
part of the discharge pipe must be slowly filled with water
using a squeeze bottle.
14. Test the unit. When the unit is mounted in place, the con-
densate pump system must be tested.
a. Be sure the Hi--Wall unit is installed on a level plane. Re-
move the front cover of the unit.
b. Slowly fill the condensate drain pan with water. Observe
thepump discharge tubing tobe surethat thepump isop-
erating.Ifcondensateisnot being discharged through the
discharge tubing, check to be sure that the lines are not
kinked or obstructed, and installation parameters have
been followed.Iftheoptionalalarm contactiswired,con-
