silavent Heat Recovery Fan HRF Quick setup guide

HEAT RECOVERY FAN
The ENERGEX will provide energy efficient ventilation in toilets, bath and shower rooms. It may also be used to
reduce humidity and ventilate other rooms such as bedrooms, living rooms, offices and hallways etc. The
ENERGEX is supplied with an optional air filter to reduce the amount of soot, dust and pollen entering the room.
The ENERGEX heat exchange fan requires a fitting kit to complete the installation. Pull-cord models should not be
installed in ceilings. Models with pull-cord override option should have the pull-cord removed (cut off) before
installing in ceilings.
HEAT RECOVERY FAN RANGE
SINGLE SPEED
ENX100
Fan unit operates whilst switch live is supplied to the unit. Designed to be used with remote switch (not supplied).
Fan unit incorporates thermo-actuator operated air inlet and outlet shutters.
ENX100P
Fan unit operates whilst switch live is supplied to unit. Operated by the integral pull cord. Fan unit incorporates
thermo-actuator operated air inlet and outlet shutters.
ENX100T
Fan unit operates whilst switch live is supplied to unit. When the switch live is turned off, the fan continues to work
for a period between 45 seconds and 30 minutes (depending on the overrun timer setting). Fan unit incorporates
thermo-actuator operated air inlet and outlet shutters.
ENX100HTP
Fan unit operates whilst switch live is supplied to unit. When the switch live is turned off, the fan continues to work
for a period between 45 seconds and 30 minutes. The fan can also be operated by the integral pull cord which
enables the fan to run for the time period set on the timer adjustment. If the fan is off, the fan can also be switched
on by the integral humidity sensor. Fan unit incorporates thermo-actuator operated air inlet and outlet shutters.
TWIN SPEED
ENX1002SC
Fan unit is designed to operate with a remote switch. The fan will run at normal speed or high speed when the
remote switch is turned on. Fan unit does not incorporate thermo-actuator operated air inlet and outlet shutters.
ENX 1002SP
Fan unit is designed to be operated by the integral pull cord. When the pull cord is operated from the OFF position,
the fan will run at normal speed. When the pull cord is operated again, the fan unit will operate at high speed.
When the pull cord is pulled again, the fan switches off (Off-Normal-High-Off). Fan unit incorporates thermo-
actuator operated air inlet and outlet shutters.
ENX 1002SCP
Fan unit is designed to operate with the integral pull cord. The fan will run continuously at low speed and will switch
to high speed when the pull cord is operated. When the pull cord is operated again, the fan returns to the low
speed. Fan unit does not incorporate thermo-actuator operated air inlet and outlet shutters.
ENX1002SHTP
Fan unit operates at high speed whilst switch live is supplied to the unit. When the switch live is turned off, the fan
continues to work for a period between 1 and 30 minutes. The fan can also be operated by the integral pull cord
which enables the fan to run at high speed for the time period set on the timer. If the fan is off, the fan can also be
switched on to a reduced speed by the integral humidity sensor. Fan unit incorporates thermo-actuator operated air
inlet and outlet shutters. (Not continuous running)
ENX1002SHB
Fan unit runs continuously at low speed and will switch to high speed when the integral humidity sensor detects a
significant increase in the level of humidity. The unit is fitted with a switch live and pull cord so that boost may be
operated independently from the humidity controls when required. Fan unit does not incorporate thermo-actuator
operated air inlet and outlet shutters.
SELV MODELS
ENX 100LV
Fan unit operates whilst switch live is supplied to transformer and the 12VAC output of the transformer is
connected to the fan. Designed to be used with remote switch (not supplied). Fan unit does not incorporate thermo-
actuator operated air inlet and outlet shutters.
ENX 100LVT
Fan unit operates whilst switch live is supplied to transformer and the 12VAC output of the transformer is
connected to the fan. When the switch live is turned off, the fan continues to work for a period of between 1 minute
and 30 minutes. Fan unit does not incorporate thermo-actuator operated air inlet and outlet shutters.
ENX 100LVHT
Fan unit operates whilst switch live is supplied to transformer and the 12VAC output of the transformer is
connected to the fan. When the switch live is turned off, the fan continues to work for a period between 1 minute
and 30 minutes. The fan can also be operated by the integral pull cord which enables the fan to run for the time
period set on the timer adjustment. If the fan is off, the fan can also be switched on by the integral humidity sensor.
Fan unit does not incorporate thermo-actuator operated air inlet and outlet shutters.
CLEANING
Cleaning and maintenance of the ENERGEX should be carried out by a qualified electrician. It is recommended that the
ENERGEX fan unit be dusted out and the filter and heat exchanger washed at 6 monthly intervals. To do this remove the front
cover as previously described. The filter and heat exchanger can now be removed. The dust can be removed from the fan unit
with a soft dry brush or vacuum cleaner.
The front cover can be washed in warm water and dishwashing liquid.
The outside of the fan body can be cleaned with a damp cloth.
The air filter should be washed in warm water with dishwashing liquid.
When clean, squeeze out any excess water BUT DO NOT WRING DRY, then layout on a flat surface to dry.
The heat exchanger should be rinsed under a cold tap and shaken to remove any surplus water
.
When all components are clean and dry, reassemble the fan in reverse.
It is recommended that every two years the fan chassis is removed from the mounting box to enable the air inlet to be
cleaned.
With the fan chassis face down on a flat surface, remove the three screws retaining the back plate.
Place the back plate to one side and dust the air inlet around the motor with a soft brush or vacuum cleaner.
When the air inlet is clean, replace the back plate making sure that no wires are trapped.
NOTE: Do not put any components in a dishwasher.
