 INSTALLATION & OPERATION MANUAL

NOTE: To avoid water damage or scalding due to valve

operation, drain pipe must be connected to the outlet of
the PRV and run to a safe place of discharge. Drain pipe
must be the same size as the valve discharge connection
throughout its entire length and must pitch downward
from the valve. No shutoff valve shall be installed
between the relief valve and the drain line. Valve lever
should be tripped at least once a year to ensure that
waterways are clear.

The heater requires water flow and positive pressure to

fire and operate properly. It must therefore be installed
downstream of the discharge side of the filter pump. See
Figure 24 and Figure 25.
A typical installation is plumbed as follows:
1. The inlet side of the filter is plumbed directly to the
discharge side of the filter pump;
2. The outlet side of the filter is then plumbed to the inlet
of the heater; and
3. The outlet of the heater is plumbed to the return line
to the pool or spa. The pump, filter and heater are
thus plumbed in series (Salt generators and chemical
feeders must be downstream of the pool heater).

A CAUTION: An additional source of heated water,

e.g. a solar heating system, must be connected to the
main line ahead of the heater inlet pipe in order for it
to act as the primary heat source. If the primary system
provides adequate heat to maintain setpoint, the heater
will not fire. Be advised that the control panel will then
display sensed water temperatures downstream of the
primary heating system, rather than the temperature of
the water exiting the pool.

Heater must be located so that any water leaks will not

damage the structure of adjacent area. CPVC or PVC pipe
may be glued directly into the half-unions provided.

Cold Weather Operation

Important Freeze Information
MODERATE CLIMATE: Heater operation can continue
during short-term cold spells. When temperatures are
between 0°F (-18°C) and 32°F (0°C), flow (continuous
pump operation) must be maintained.

A CAUTION: Do not use the heater to maintain

water temperatures just above freezing or for freeze
protection. When heater is used during freezing weather,
care must be taken to avoid freeze-ups. Continuous
pump operation is a must. Additional protection may be
required. The heater is not warranted against freeze-ups.

IMPORTANT NOTICE: These instructions are intended for the use of qualified personnel who are specifically trained
and experienced in the installation of this type of heating equipment and related system components. Installation and
service personnel may be required by some states to be licensed. Persons not qualified shall not attempt to install this
equipment nor attempt repairs according to these instructions.

Problem Possible Cause Corrective Action

LCD text flickering or no text Low or no voltage to control board................... Check for 24VAC at control board P6.
Check transformer wiring to 240V or 120V.
Harmonics, or whining noise Unitherm governor inoperative.......................... Check movement by putting in hot water (above120°F [49°C] or
higher)

Bypassing too much water............................... Inspect bypass for movement, if no movement, replace

Unitherm governor not functioning................... Replace if no movement when heated

Sooting High flow rates.................................................. Reduce by adding manual bypass valve

Adjust manual bypass valve until heater outlet water temp is between
105°F and 120°F (40°C and 49°C)
Unitherm governor inoperative......................... Check movement by putting in hot water (above 120°F [49°C] or
higher). If no movement, replace
*Air starvation................................................... Refer to installation instructions
*Improper venting............................................. Follow recommended installation instructions

*Insects or debris clogging burner intake ports. Clean burners

Flame outage or Flame strength Low gas pressure............................................. Adjust gas pressure
below 2 μA

Restricted/dirty igniter....................................... Clean igniter and burners

Takes too long to heat pool or spa Under-sized heater........................................... Calculate heating capacity of heater
Htr. output (BTUH) = approx. degF rise/hr
Pool gallonage x 8.33
or refer to heater sizing chart
This does not take into account heat loss due to weather
Filter not running long enough.......................... Reset time clock

Dirty filter.......................................................... Clean filter

Gas line or meter undersized........................... Refer to installation instructions. See page 18.

Leaking at heat exchanger Overacid........................................................... Replace heat exchanger and maintain proper water chemistry

Gasket brittle and leaking - Heater running after pump shuts off................. See Pressure Switch Adjustment, See page 38.

Fan not running, "Diff Sw Open" or Incorrect blower jumper.................................... Check blower jumper matches 240V or 120V power supply.
"Fan Lockout"
Fan relay.......................................................... Check control board Fan relay terminals “Power” and “Blower”.
If relay is stuck open or close, replace control board.
Fan Connection................................................ Loose connection or failed motor. Prolonged exposure to power with

network meets these specifications: Router Extender
• Supported Networks - Wi-Fi 2.4GHz (802.11 b/g/n).
• Password encryptions - WEP, WPA, WPA2.
• Wi-Fi signal icon of 2 bars (-60dB) or better at heater
location. Figure 138. Wi-Fi Extender

4. Update Raymote app to the latest version.

Figure 136. Wi-Fi Signal

2. Use the built-in Wi-Fi network options in your

cellphone or use a Wi-Fi network scanner app like Figure 139. Update Application
Fing Network Scanner for iPhone or Wi-Fi Analyzer
for Android smart phones, to check signal strength. 5. Power-cycle your heater and restart Raymote app.

If you are having troubles connecting your Heater to

the Raymote app, try these common solutions:
• Check that Wi-Fi signal name and password are
correct.
• In case of a change, proceed to Reset Wi-Fi credential
from Heater Touchscreen and reconnect the heater
with Raymote app.

Figure 140. Restart Raymote

6. Check the settings on your router or Wi-Fi access

point.
• If needed, enable a dedicated 2.4 GHz network.
5GHz signals are not compatible with Raymote.
• When applicable, ensure to have the permissions
from IT or Building manager.
• Check if MAC address whitelisting is required.
• Check if Static IP is required.

A While adjusting the cams of an actuator, disconnect

the other actuators to avoid energizing them in inverse

A After individually adjusting each actuator, and before

energizing the circuit, ensure all the actuators have the
"position" switch in the same setting. Having mixed
settings may cause electrical damage to the actuators.

 INSTALLATION & OPERATION MANUAL

NOTE: Ensure to select proper relay coil voltage

and terminal current rating per your application.

● Always check the voltage specification of the

field-supplied relay. Check coil activation voltage.

● When using power from the 24V AC transformer,

ensure to use a relay with coil voltage for 24V AC.

● If a different voltage is required to activate the relay

coil, ensure to use the proper power supply instead of
the 24V AC transformer.

For single-speed pumps, blowers and other applications rated above 3 Amps, use field-supplied DPST relay.
