APPENDIX A
____ 1. Is the unit base properly leveled, grouted and
secured?
____ 2. Are all lubrication points properly lubricated?
____ 3. Is the outlet side of the high temperature regulat-
ing valve connected to the drain with tubing or
pipe size 3/8" or greater?
____ 4. Is the shut-off valve to the pressure transmitter(s)
open?
____ 5. Is the shut-off valve to the pump suction open?
____ 6. Is the shut-off valve on the discharge line open?
____ 7. Is the bypass valve, if used, closed? This valve
may be left open if a check valve is installed in
series with it.
____ 8. Are the stop cocks for the check feature on the
PRV open? They must never be completely closed
during normal operation. Throttle cock if check
slamming is noted.
____ 9. Is the piping properly supported so as to prevent
strains on unit?
____ 10. Is the system, including the pumps and PRV’s,
purged of debris and air?

The tank must be empty of water when checking
the air charge.

header open?
APPENDIX B
APPENDIX B
____ 1. Does the feeder line voltage correspond to the unit
voltage? Check the unit nameplate or motor ter-
minal connection.
____ 2. Are the feeder wires correctly sized for the load?
____ 3. Are the fuses correctly sized? They must not
exceed 1.75 times the full load current of the
motor. Usual sizing is 1.15 to 1.5 times the full
load current.
____ 4. Is the unit properly grounded?
____ 5. Have all the power terminals in the control panel
been checked for tightness? This is imperative
since stranded wires tend to "flow" and become
loose after initial installation.
____ 6. Are motor overloads set properly? Set the over-
loads to FLA as a minimum and SF x FLA as a
maximum.
____ 7. Is the pump rotation correct?
CAUTION: Seal Damage may occur. Do not run
pumps dry. Fill and vent the pump volute prior to
operation.
