• Not maintaining proper chemical levels and/or not
c
hanging the water on a regular basis can promote
unsanitary water conditions.
Not maintaining proper water chemistry levels as
listed in the Operating Restrictions section can cause
damage to the heat exchanger and void any warran-
ty claims.
CORROSION
The corrosive action of the pool or spa water on the heat
exchanger is increased by the following conditions:
a) Low pH - acidity
b) Low Total Alkalinity - bicarbonates
c) Low Calcium Hardness - soft water
WATER CHEMISTRY TESTING
• Pool/Spa owner should purchase and use regularly a
test kit that will at a minimum measure chloride, pH
level and alkalinity.
• A professional service technician should perform a
more extensive chemical testing on a periodic basis.
START-UP PROCEDURES
1. Close isolation valves on the inlet and outlet piping
of the heat exchanger, isolating the heat exchanger
from the pool or spa, and open the by-pass piping
valve.
2. Remove all timing controls, allowing the filtering
system to run continuously.
3. Establish proper water chemistry in the pool or spa.
4. After establishing proper water chemistry, open the
isolation valves at the heat exchanger and close the
by-pass valve.
5. Set the thermostatic control to the desired water tem-
perature.
6. Continue running the filter system until the water
reaches the desired temperature setting.
WARNING
SPRING AND FALL OPERATION
During cold periods (those above freezing weather)
maintain a minimum temperature setting (65ºF to 70ºF)
for periodic usage. This will prevent the water from
becoming chilled and will reduce the amount of time to
reheat to the desired temperature.
WINTERIZING
Pool/Spa
• Completely drain the pool/spa piping system by
opening the drain valve shown in Figure 1 and 2.
• Use compressed air to blow out any standing water
in the piping and filter system components.
Boiler
• If the heat exchanger is mounted in an unheated
area, isolate and drain the boiler system piping at the
heat exchanger.
• Use compressed air to blow out any standing water
in the system piping and heat exchanger.
• The heat exchanger is compatible with inhibited
propylene glycol solution with a maximum 50/50
mixture.
Do not use automotive or ethylene glycol antifreeze, or
any undiluted antifreeze. This can cause severe per-
sonal injury, death or substantial property damage.
• Check the pH level of the glycol solution. If dif-
ferent than a pH level of 7.0, the antifreeze must
be replaced immediately.
PERIODICAL MAINTENANCE - MAXI-FLO
®
• Check all valves, piping and fittings for visible
leaks.
• Check function of all field installed controls.
Consult the control manufacturer’s instructions.
• Inspect the heat exchanger for scaling or particles.
Flush the heat exchanger with a light solution (5%
concentration) of phosphoric acid to remove any
scaling.
