a) Re-install front access panel.
b) Place a garden hose into the pool side inlet of the heat
pump; wrap a clean rag around the hose to form a
temporary seal.
c) Turn on the garden hose water supply.
d) Allow water to run through the heat exchanger for 2-3
minutes; fresh water should be seen exiting the pool's out-
port.
e) Place a garden hose into the source-side inlet of the heat
pump; wrap a clean rag around the hose to form a
temporary seal.
f) Turn on the garden hose water supply.
g) Allow water to run through the heat exchanger for 2-3 minutes; fresh water should be seen
exiting the out-port connection unions.
h) After flushing is complete, shut off and remove the water supply.
i)
Place an air hose into the pool inlet of the heat pump; wrap a clean rag around the hose to
form a temporary seal.
j)
Push all water from the water circuit using compressed air at approximately 50 psig. The
residual water should be forced out of the pool out connection.
k) Allow compressed air to blow into the heat pump inlet connection unions for at least 15-20
seconds after water stops coming out of the pool outlet.
l)
Repeat process on source side.
m) Partially reconnect plumbing connection unions.
3.3 Planned Maintenance
An annual inspection and maintenance program is strongly recommended starting one (1) year after
installation of heat pump. See Figure 6 for recommended inspection checklist. AquaCal AutoPilot can
perform this service in limited areas. Contact Customer Support for more information.
