CAUTION: To avoid equipment damage, DO
NOT leave system filled with water in a building
without heat during the winter unless anti-freeze
is added to system water. Coax coils never fully
drain by themselves and will freeze unless win-
terized with anti-freeze.
10. System Water Loop: Verify all air is bled from
the system. Air in the system impedes unit
operation and causes corrosion in the system
piping.
11. Unit Filters: To avoid unit damage and
maximum performance, ensure the unit filter is
clean.
12 Unit Fans: Manually rotate fans to assure free
rotation. Ensure fans are properly secured to
the fan shaft. Do not oil fan motors on start-up
since they are lubricated at the factory.
13. System Control Center: To ensure control of
the temperature set-points for operation of
the system’s heat rejector and boiler, examine
the system control and alarm panel for proper
installation and operation.
14. Miscellaneous: Note any questionable aspects
of the installation.
1. Voltage: Ensure voltage is within the
utilization range specifications of the unit
compressor and fan motor.
2. System Water Temperature: Ensure it is
within an acceptable range to facilitate
start-up. (When conducting this check,
also verify proper heating and cooling set
points.)
3. System Water pH: Verify system water
acidity. (pH = 7.5 or 8.5) Proper pH
promotes the longevity of hoses and heat
exchangers.
4. System Flushing: Properly clean and flush
system periodically. Ensure all supply and
return hoses are connected end-to-end
to facilitate system flushing and prevent
fouling of the heat exchanger by system
water. Water used in the system must be
of potable quality and clean of dirt, piping
slag, and chemical cleaning agents.
5. Closed-Type Cooling Tower or Open Tower
with Heat Exchanger: Check equipment
for proper temperature set points and
operation.
6. Balanced Water Flow Rate to Heat
Pump:: Verify the inlet and outlet water
temperatures are recorded as each heat
pump unit is started. This check will
eliminate nuisance unit trip-outs resulting
from water velocities which are either too
low or too high; it can also prevent the
occurrence of erosive water flow rates.
7. Standby Pump: Verify the standby pump
is properly installed and in operating
condition.
8. System Controls: To ensure no catastrophic
system failures occur, verify system controls
are functioning and the sequencing is
correct.
9. Freeze Protection for Water System: Verify
freeze protection is provided for the
outdoor portion of the loop water system.
Inadequate freeze protection can lead to
expensive tower and system piping repairs.
When the installation is complete and the system is cleaned and flushed, follow the System Checkout
procedure outline below.
