START-UP PROCEDURE
Do not start the air handler or water
heater until ALL air has been purged!
1. Fill the boiler loop or water heater
with water, but do not start it.
2. Purge all air from the boiler heating or
domestic water system.
3. Purge all air from the space-heating
loop by closing the isolation valve on
the return leg of the loop and open
the drain to purge air. Open the return
leg isolation valve and then close the
drain valve.
4. Start the boiler or water heater
according to the manufacturer’s
instructions. Set the design water
temperature and wait for the system
to shut off. You can check that the
water heater is set properly during the
warm up by running a small amount
of water into a glass in a sink while
the water heater is warming up. Using
a thermometer measure the
temperature of the water as soon as
the water heater burner shuts off. If
the set-point temperature is too low or
is above 140F/60C, reset the tank
control, run water until the burner
starts again and repeat the
measurement.
5. Turn on the power to the air handler
and set up the electronic controller as
per instructions in the Controls User
Manual. This is important to ensure
that the correct airflows are used for
the equipment as installed.
6. Set the room thermostat for heat to
energize the fan and pump. If a
gurgling sound is present, it should
subside within one minute. If noise is
still present after one minute, repeat
step 3 to purge air as necessary.
7. Check pipes for heating to make sure
there is flow and feel the pump motor
to see if it is running hot.
SERVICE AND MAINTENANCE
Filter
The filter should be inspected monthly
and replaced as required.
Duct cleaning
If proper filter maintenance is adhered to,
duct cleaning will not be required for the
life of the equipment.
Coils
Air conditioning and heating coils should
not require cleaning if the filter
maintenance schedule is adhered to. If a
filter is damaged or collapses from
plugging, dust may foul the coils. If this
happens, replace the filter and carefully
vacuum the heating coil. The fan may
need to be removed to gain access to
the face of the heating coil.
Air conditioning coil
At the start of each cooling season,
check the drain connection to the cooling
coil to ensure it is free of debris. If a
plugged air conditioning coil is
suspected, call a service technician for
testing and cleaning
