Turbotemp 125 Pool and Spa Heater Installation and User’s Guide
For outdoor heaters in freezing climates, shut the heater down and drain it for winter as follows:
1. Turn off electrical supply to the heater and pump.
2. Close main gas control valve and manual gas valve (located outside the heater). Turn switch
on heater gas valve to OFF.
3. In colder climates where they may be required, open drain cock located on the bottom of
the manifold adapter, and drain the heat exchanger and manifold adapter completely. If
heater is below pool water level, be sure to close isolation valves to prevent draining the
pool (isolation valves are not required and should not be used on heaters installed above
pool water level except when needed for winterizing valves). Assist the draining by blowing
out the heat exchanger through the pressure switch fitting with low pressure compressed air
(less than 35 kPa or 5 PSI).
Explosion hazard.
Purging the system with compressed air can cause components to
explode, with risk of severe injury or death to anyone nearby. Use only a low pressure (below
5 PSI or 35 kPa), high volume blower when air purging the heater, pump, filter, or piping.

WARNING
4. Remove the Water Pressure Switch. Plug the port in the manifold to prevent bugs and dirt
from getting into the manifold.
5. Drain the plastic inlet/outlet manifold through the outlet pipe. If the pipe does not drain
naturally to the pool, install a drain cock in the outlet pipe to drain the manifold.
6. Cover air inlet grate with a plastic bag to prevent bugs, leaves, etc., from getting into the
heater.
NOTICE:
Water trapped in the heater can cause freeze damage. Allowing the heater to freeze
voids the warranty.
To return the heater to service after winterizing:
1. Connect the INLET and OUTLET unions to the system plumbing. Check that they are
connected correctly and there are no water leaks.
2. Before starting the heater, circulate water through the heater for several minutes until all air
noises stop. See also “BEFORE START-UP” (page 1) and “CARE AND MAINTENANCE”
(page 35).
(See additional notes under Important Notices in Introduction.)
Heat exchanger damage resulting from chemical imbalance is not covered by the
warranty.

CAUTION
MAINTAINING POOL TEMPERATURE
To maintain pool temperature, ensure the heater switch and valving are reset to pool settings
after using the spa.
ENERGY SAVING TIPS
1. Keep the pool or spa covered when not in use. This will reduce heating costs, reduce water
evaporation, conserve chemicals and reduce load on the filtering system.
2. Reduce pool thermostat to 26° C (78° F) or lower; reduce spa temperature to 38° C (100° F).
This is accepted as being the most healthy temperature for swimming.
3. Use a time clock to start the filter pump at 6 AM. or later. The swimming pool looses less heat
after daybreak.
4. For pools used only on weekends, lower the thermostat setting by 12° C to 9° C (10° F
to 15° F) during the week to reduce heat loss. A properly sized heater will restore normal
temperature within one day.
5. Turn the heater off when the pool will not be used for an extended period.
6. Follow a regular program of preventive maintenance for the heater each new swimming
season. Check operation of the heater and its controls.
CHEMICAL BALANCE
POOL AND SPA WATER
Your pool heater was designed specifically for your spa or pool and will give you trouble-free
service, provided you keep your water chemistry in proper condition.
Water chemistry should follow good swimming pool water chemistry practices. When using a
chlorinator, install it down stream from the heater and at a lower level than the heater outlet.
Install a corrosion resistant positive seal “Check Valve”, between the heater and the chlorinator
to prevent concentrated chemicals from back-siphoning into the heater. Back-siphoning is
most likely to occur when the pump stops, creating a pressure-suction differential. Do NOT
sanitize the pool by putting chlorine tablets or sticks into the skimmer(s). When the pump is off,
this will cause a high concentration of chlorine to enter the heater, which could cause corrosion
damage to the heat exchanger.
Three major items that can cause problems with your pool heater are: improper pH, disinfectant
residual, and total alkalinity. These items, if not kept properly balanced, can shorten the life of
the heater and cause permanent damage.
• Operating this heater continuously at water temperatures below 20° C (68° F) will
cause harmful condensation and will damage the heater and void the warranty.
• If the heater has been drained for freezing condition, do NOT turn “ON” until the
system is circulating water.
• Water trapped in the heat exchanger can result in freeze damage to the exchanger
or headers. Freeze damage is specifically not covered by the warranty.
• When starting the heater for the swimming season with a water temperature below
10°C (50° F), the heater may be used to heat the water; however, ensure the heater
operates continuously until the water temperature reaches the heater’s minimum
setting of 20° C 68° F). During cold weather, if there is no danger of freezing, operate
the filter pump continuously even if the heater is not operating. If air temperatures
are expected to drop below freezing (0° C / 32° F), shut down the heater and
winterize it.
