Hydronic Fan Convectors
Fan Convectors are designed to provide heat in a minimum of space using forced convection. MYSON’s efficient
tangential fan design forces air uniformly across a low pressure drop heat exchanger, resulting in a high heat
output from a very compact space.
MYSON Fan Convectors all have several features in common:
• Fan bearings are porous bronze sleeves for longer life and quieter service
• Heat exchangers feature copper tubing expanded onto aluminum fins for greater heat transfer efficiency
• Each model has been certified by independent testing by ATL* to deliver 100% of the published heat output
• Each unit is manufactured to the high standards of MYSON’s ISO 9002 certification
• Each unit comes with at least a 3 year warranty; coverage for heat exchangers is extended to 10 years
Technical specifications for the MYSON Fan Convector family are given on the following pages, showing specific
dimensions and configuration, heat output, weights and head requirements.

EZ-Hose Kit
TM
Flexible Hose Connectors
MYSON’s EZ-Hose kit is specifically designed for installation with MYSON Fan
Convectors. It allows the unit to be easily removed from the cabinet for quick
connection and easy-access maintenance. These flexible hoses can save time
and money, and they quickly solve those difficult access problems.
EZ-Hose Kit... save time and money. MYSON’s hose kit is so easy to use. The
flexible hoses allow you to install the MYSON Fan Convectors from outside
the cabinet. There’s no need to remove the cabinet or cut ugly access doors
in the bottom of the cabinet.
EZ-Hose Kit... easy access installation. MYSON’s two-hose system installs in
minutes. Two MonoFlo tees (not included in kit) are installed in the heating
loop. The hoses are then used to connect the convector to the heating loop.
EZ-Hose Kit... maintenance is hassle-free. If you should need to service the
MYSON Fan Convector, the EZ-Hose has an ample 30 inches of flexible hose so
you can slide the unit completely out for maintenance. The Ball Valve with
the slotted shut-off, enables you to disconnect the unit while maintaining the
pressure of the system and you do not have to drain the system.
Features:
■ Flexible — Designed with installation
in mind, these 30" hoses with a
1
/2" female compression fitting
on one end and a ball valve with
screwdriver slot on the other end,
provide enough length to allow
installation outside of the cabinet.
■ Tested — Maximum operating
temperature of 250°F and working
pressure of 100psi.
■ Easy Installation — Installs in a
fraction of the time required for
conventional pipe installation... that
saves time and money.
■ Backed with confidence — MYSON
guarantees 100% satisfaction.
■ Compatibility — May be used
with both water- and antifreezeprotected heating systems.

WHISPA E ELECTRIC KICKSPACE HEATER SPECIFICATIONS — Engineered to be efficient.
Fan Unit... A highly efficient 110 cfm
tangential fan extends the full width of
the heating element, giving extremely
quiet, trouble-free operation. All
units have aluminum fans, sealed
motor bearings, and permanently
lubricated bearings.
6
Controls... Units have a lighted fan switch
to indicate power “ON.” Heat is controlled
using a dual rocker switch — both switches
“OFF” for fan only, either switch “ON” for
800 Watts (Low), and both switches “ON”
for 1600 Watts (High). Each unit has a high
temperature limit switch to shut off power
in the event of excessive temperature
resulting from restricted airflow.
Construction... The chassis is manufactured
from zinc-coated painted steel. The
grill is hardened aluminum for strength
and durability.
Electrical connections... Wiring connections
are supplied through the rear of each
unit. Motor is 110V, 60Hz and is ETL
listed. Dual heating elements draw a
total of 15 amps on the high setting.

fan extends the full width of the heat
exchanger, giving extremely quiet,
trouble-free operation. All units have
aluminum fans, sealed motor bearings,
and permanently lubricated porous
bronze sleeve fan bearings.
Heat Exchanger... Fin tube heat exchanger
is a manifold design with copper water
conduits expanded to create firm contact
with the surrounding aluminum fins.
Special air turbulator design maximizes
the rate of heat transfer. All units are
hydraulically tested to 300 psi.
Controls... The Lo-Line Heater Cooler has
a three speed fan, best controlled by
a 110V AC heat/cool thermostat with
3-speed sub-base. (By others.)
Tamper-Proof Controls Cover... All units
include a tamper-proof controls cover
which conceals all electrical controls
from unauthorized usage.
Construction... The chassis is manufactured
from zinc-coated painted steel.
Water Connections…Supply and return are
1
/2" copper to compression isolation valves
in the lower left corner of the unit. An air
vent(s) for bleeding the convector is easily
accessed through the front of the unit with
a screwdriver. No special key is needed.
Warranty…MYSON offers a full ten year
warranty on the heat exchanger and a full
three year warranty on the fan motor.

Kickspace Fan Convector Installation
1. A kickspace heater must have a free flow of air through the unit. We have designed our grills to allow for sufficient
airflow. The opening in the kickspace must allow unrestricted airflow. (See drawing below.) Looking at the grill,
you should not be able to see any part of the kickboard. Failure to do so will cause the motor to overheat and
void the warranty.
2. The kickspace heater needs to be sized appropriately for the job. For proper sizing, use the ratings at normal speed.
If the unit needs to be in the boost or high setting to heat the room adequately, then the kickspace heater is too
small. Running the unit in boost or high for extended periods of time will shorten the motor fan assembly life.

MYSON EZ-Hose Kit
The MYSON EZ-Hose Kit is designed specifically for use with the WH II 5000 and WH II 9000 Kickspace Heaters. While it
may be used for other hydronic products, MYSON will not be responsible for compatibility.
Components:
2 - 30" braided stainless steel hoses, 1/2" compression x 1/2" MPT
2 - Screwdriver slot ball valves, 1/2" compression x 1/2" FPT
Assemble the male end of the hose to the female end of the ball valve using the recommended Loctite #565 thread
sealant. Connect the compression end of the hoses to the stub-outs on the kickspace unit. Make sure that the return
side hose is connected to the top stub-out so that air will be forced through the heat exchanger to where it can be
removed at the air vent. Connect the compression ends of the ball valves to the appropriate supply and return pipes
from the heating system.
