4. INSTALLATION
4.1 LOCATION
The Hi-E Dry 195 can be installed in a variety of locations to meet the owner’s needs as listed below. In
all cases keep the following cautions in mind:
» It is designed to be installed INDOORS ONLY.
» If used near a pool or spa, be certain there is NO chance the unit could roll into the water or be
splashed and that it is plugged into a GROUND FAULT INTERRUPTER.
» Avoid discharging the air directly at people, especially in pool areas.
» A flooded unit is not covered by warranty.
» DO NOT hang the Quest Hi-E Dry 195 from its’ cabinet.
» The minimum floor area of the room shall be 28 m
2
(square meters).
» Keep any required ventilation openings clear of obstruction.
» Ducts connected to the dehumidifier shall not contain a POTENTIAL IGNITION SOURCE.
» Supply and return air shall be directly ducted to the space. Open areas such as false ceilings shall
not be used as a return air duct.
Unventilated Areas
» Unventilated Areas where the Quest Hi-E Dry 195 is installed or stored need to be so constructed
that should any refrigerant leak, it will not stagnate so as to create a fire or explosion hazard.
» Quest Hi-E Dry 195 shall not be stored or ducted into one or multiple rooms with continuously
operating open flames (for example an operating gas appliance) or other POTENTIAL IGNITION
SOURCES (for example an operating electric heater, hot surfaces). A flame-producing device may be
installed in the same space if the device is provided with an effective flame arrest.
4.1A IN HUMID AREA, NO DUCTING
The simplest installation is to place the Hi-E Dry 195 in the humid area with no ducting. The air inlet on
top & outlet on the side must be at least 1’ from walls and other obstructions to air flow.
4.1B IN HUMID AREA, DUCT INLET AND/OR OUTLET
If the humid area is very large or has high ceilings, dehumidification can be improved by adding an inlet
and/or outlet duct to circulate and destratify stagnant areas. For a large area, add inlet or outlet ducting
to create flow across the area’s greatest length.
For areas with ceilings higher than 12’, use an inlet duct to draw warm, moist air from near the ceiling.
See section 2.4 for attaching duct collars & ducting.
4.1C IN REMOTE AREA, DUCT OUTLET ONLY
This works well if there is an adequate air flow path between the two rooms; e.g., high door undercut,
louvered door or wall grill. There are several potential disadvantages to using this method. First, humid
air is drawn into the room where the Hi-E Dry 195 is located. Second, to accurately sense humidity,
the blower in the Hi-E Dry 195 may need to run continuously to draw air from the humid room into the
Hi-E Dry 195 room. Third, a slight negative pressure is created in the room with the Hi-E Dry 195 which
could back draft open combustion devices located there. If such devices are present, call the factory for
specific instructions before using this installation method or consider the option below.
7
HI-E DRY 195 INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS
QUESTCLIMATE.COM(877) 420-1330
4.1D IN REMOTE AREA, DUCT INLET ONLY
When the Hi-E Dry 195 is located in a room separate from the main area to be dehumidified, it may
be desirable to dehumidify and/or slightly pressurize that room. Pressurization assures that open
combustion devices do not back draft as would be the case if the room was sufficiently de-pressurized.
This can be accomplished by installing a duct from the humid room to the Hi-E Dry 195 inlet and by
allowing the Hi-E Dry 195 to discharge the dehumidified air into the room in which it’s located. An
adequate air flow path must exist between the two rooms for this method to work well.
4.2 ELECTRICAL REQUIREMENTS
The Hi-E Dry 195 plugs into a common grounded outlet on a 20-amp circuit. It draws between 3 and 7
amps under normal operating conditions. If used in a wet area (pool, spa room, or basement prone to
flooding), a ground fault interrupter protected circuit is required.
If an extension cord is required, it must have a minimum of 14 gauge conductors if less than 25 feet long
and 12 gauge if greater than 25 feet.
4.3 CONDENSATE REMOVAL
The Hi-E Dry 195 is equipped with an internal condensate pump to remove the water that is condensed
during dehumidification. This allows the condensate to be pumped 30’ with the attached hose. If the
condensate must be pumped more than 17 feet above the unit, a second pump must be added to relay
the condensate. The condensate pump is mounted inside the Hi-E Dry 195 as a permanent, integral part
of the unit. It includes a safety switch feature that prevents flooding by turning off the Hi-E Dry 195 if
the pump fails.
4.4 DUCTING
4.4A OPTIONAL DUCTING
A ducting kit consisting of one 12” Inlet duct collar, one 10” Outlet duct collar and one block off plate is
available from the factory that will allow ducting to be attached to the inlet and outlet of the Hi-E Dry
195. Attach the inlet collar to the top of the unit.
4.4B DUCTING FOR DEHUMIDIFICATION
Ducting the Hi-E Dry 195 requires consideration of the following points:
Duct Sizing: For total duct lengths up to 25’, use a minimum 12” diameter round or equivalent
rectangular for the intake and 10” diameter round or equivalent rectangular for the outlet. Grills or
diffusers on the duct ends must not excessively restrict airflow.
Isolated Areas: Effective dehumidification may require that ducting be branched to isolated, stagnant
areas. Use 8” diameter branch ducting to each of two or three areas; use 6” to each of four or five
areas; use 4” to each of six or more areas.
4.4C DUCTING FOR FRESH AIR
Fresh air can be brought into the structure continuously by connecting a duct from outside to the Hi-E
Dry 195 inlet and by turning on the fan ON mode. Advantages of this form of ventilation include:
1. Outside air is filtered before entering the building.
2. Outside air will be dehumidified before entering if the Hi-E Dry 195 is running.
3. Drawing air from outside and blowing inside aids in pressurizing the structure. This helps prevent
unfiltered and undehumidified air from entering elsewhere. It also reduces the potential for
8
HI-E DRY 195 INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS
QUESTCLIMATE.COM(877) 420-1330
carcinogenic radon gas to enter.
4. The need for an alternate ventilation device may be eliminated.
An insulated 4” diameter duct is generally sufficient to provide up to 70 CFM of outside air. A 6” duct
with an adjustable damper is recommended for higher flows. Large quantities of outside air will impact
Hi-E Dry 195 performance positively or negatively, depending upon the difference between inside and
outside air conditions. Consult the factory by calling 1-800-533-7533 for recommendations regarding the
use of higher flows with your specific application.
The outside air duct should be connected into the main inlet duct close to the unit. If no other inlet duct
is used, it may be necessary to obstruct the inlet of the Hi-E Dry 195 to ensure adequate ventilation.
5. OPERATION
9
HI-E DRY 195 INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS
QUESTCLIMATE.COM(877) 420-1330
5.1 HUMIDITY CONTROL ADJUSTMENT
The dehumidifier will run continuously until the relative humidity (RH) is reduced to the
humidity control setting. Setting the humidity control to lower RH levels will NOT increase
the unit’s dehumidification rate, it will simply run longer to reduce the area’s RH to the
setting. The Hi-E Dry 195 unit (and refrigerant based dehumidifiers in general) will reduce
a warm space’s RH to a lower level than that of a cool space. It is therefore pointless to
set the humidity control to excessively low levels in cool rooms. Doing so will result in long
periods of ineffective dehumidifier run time.
A quality humidity meter is recommended to accurately monitor humidity levels. For a
quote on a quality humidity meter, call the factory.
5.2 FAN ON MODE
Turning the fan mode ON will cause the unit’s internal blower to run continuously, whether
the unit is dehumidifying or not. This function is desirable if the unit is used for air
circulation or fresh air ventilation.
5.3 PURGE WATER
The condensate pump will collect water before sending it through the condensate hose. To
purge water from holding tank, Hold
→
for 3 seconds within purge menu.
5.4 DEFROST CONTROL
When the Hi-E Dry 195 is used in a cool area, frost will form on the cooling coil as it
dehumidifies. When enough frost forms, the defrost Thermistor will initiate the timed
defrost cycle. The cycle periodically turns off the compressor while allowing the blower to run. The air
that the blower draws through the cooling coil melts the frost.
The defrost cycle is automatic and designed for optimum performance above 40°F.
5.5 POWER DOWN
Navigate to Power Down menu ad press power button to turn off unit. See section 3.3 to

6.1 AIR FILTER
The Hi-E Dry 195 is equipped with a 2” thick, MERV 11 pleated fabric air filter that must be checked
regularly. Operating the unit with a dirty filter will reduce the dehumidifier’s capacity and efficiency and
may cause the compressor to cycle off and on unnecessarily on the defrost control.
Replacement filters can be ordered from the factory or purchased locally if available. DO NOT operate
the unit without the filter or with a less effective filter as the heat exchange coils inside the unit could
become clogged and require disassembly to clean.
7. SERVICE
CAUTION: Servicing the Hi-E Dry 195 with its high-pressure refrigerant system and high
voltage circuitry presents a health hazard which could result in death, serious bodily
injury, and/or property damage. Only qualified service people should service this unit.

7.1 WARRANTY
A warranty certificate has been enclosed with this unit. Read it before any repair is initiated. If a
warranty repair is required, call the factory first at 1-800-533-7533 for warranty claim authorization and
technical assistance.
7.2 TECHNICAL DESCRIPTION
Refer to Figure 3. The Hi-E Dry 195 uses a
refrigeration system similar to an air conditioner’s to
remove heat and moisture from incoming air, and add
heat to the
air that is discharged.
Hot, high-pressure refrigerant gas is routed from the
compressor to the condenser coil. The refrigerant
is cooled and condensed by giving up its heat to the
air that is about to be discharged from the unit. The
refrigerant liquid then passes through two capillary
tubes, which cause the refrigerant pressure and
temperature to drop. It next enters the evaporator
coil where it absorbs heat from the incoming air and
evaporates.
The evaporator operates in a flooded condition, which
means that it should always be full of liquid refrigerant
during normal operation. A flooded evaporator should
maintain constant pressure and temperature across the
entire coil, from inlet to outlet.
The mixture of gas and liquid refrigerant enter the accumulator after leaving the evaporator coil. The
accumulator prevents any liquid refrigerant from reaching the compressor. The compressor evacuates
the cool refrigerant gas from the accumulator and compresses it to a high pressure and temperature to
repeat the process.

HI-E DRY 195 INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS
QUESTCLIMATE.COM(877) 420-1330
7.3 SERVICE PERSONNEL
Only qualified HVAC or electrical contractors are allowed to conduct maintenance, service and/or repair
operations on Quest Hi-E Dry 195 machines. Examples include but are not limited to breaking into the
REFRIGERATION circuit, opening of sealed components, and/or opening of ventilated enclosures.
Prior to beginning work on the Quest Hi-E Dry 195 machine, safety checks are necessary to ensure that
the risk of ignition is minimized.
» For repair to the REFRIGERATION SYSTEM, a qualified contractor should first establish a controlled
procedure so as to minimize the risk of a flammable gas or vapor being present while the work is being
performed
» All maintenance staff and others working in the local area shall be instructed on the nature of work
being carried out. Work in confined spaces shall be avoided.
» The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure
the technician is aware of potentially toxic or flammable atmospheres. Ensure that the leak detection
equipment being used is suitable for use with all applicable refrigerants, i.e. non-sparking, adequately
sealed or intrinsically safe.
» If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate
fire extinguishing equipment shall be available to hand. Have a dry powder or CO2 fire extinguisher
adjacent to the charging area.
» No person carrying out work in relation to a REFRIGERATION SYSTEM which involves exposing
any pipe work shall use any sources of ignition in such a manner that it may lead to the risk of fire
or explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently
far away from the site of installation, repairing, removing and disposal, during which refrigerant
can possibly be released to the surrounding space. Prior to work taking place, the area around the
equipment is to be surveyed to make sure that there are no flammable hazards or ignition risks. “No
Smoking” signs shall be displayed.
» Ensure that the area is in the open or that it is adequately ventilated before breaking into the system
or conducting any hot work. A degree of ventilation shall continue during the period that the work
is carried out. The ventilation should safely disperse any released refrigerant and preferably expel it
externally into the atmosphere.
The following checks shall be applied to installations using flammable refrigerants:
» Where electrical components are being changed, they shall be fit for the purpose and to
the correct specification. At all times Therma-Stor’s maintenance and service guidelines
shall be followed. If in doubt, consult Therma-Stor’s technical department for assistance.
» The actual REFRIGERANT CHARGE is in accordance with the room size within which the
refrigerant containing parts are installed;
» The ventilation machinery and outlets are operating adequately and are not obstructed;
» Marking to the equipment continues to be visible and legible. Markings and signs that are
illegible shall be corrected;
» Dehumidifiers are installed in a position where they are unlikely to be exposed to any
substance which may corrode refrigerant containing components, unless the components
are constructed of materials which are inherently resistant to being corroded or are
suitably protected against being so corroded.
12
HI-E DRY 195 INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS
QUESTCLIMATE.COM(877) 420-1330
7.3A CHECKS TO ELECTRICAL DEVICES
Repair and maintenance to electrical components shall include initial safety checks and
component inspection procedures. If a fault exists that could compromise safety, then no
electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the
fault cannot be corrected immediately but it is necessary to continue operation, an adequate
temporary solution shall be used. This shall be reported to the owner of the equipment so all
parties are advised.
Initial safety checks shall include:
» that capacitors are discharged: this shall be done in a safe manner to avoid
possibility of sparking;
» that no live electrical components and wiring are exposed while charging,
recovering or purging the system;
» that there is continuity of earth bonding.
7.3B REPAIRS TO SEALED COMPONENTS
» During repairs to sealed components, all electrical supplies shall be disconnected
from the equipment being worked upon prior to any removal of sealed covers,
etc. If it is absolutely necessary to have an electrical supply to equipment during
servicing, then a permanently operating form of leak detection shall be located at
the most critical point to warn of a potentially hazardous situation.
» Particular attention shall be paid to the following to ensure that by working on
electrical components, the casing is not altered in such a way that the level of
protection is affected. This shall include damage to cables, excessive number
of connections, terminals not made to original specification, damage to seals,
incorrect fitting of glands, etc.
» Ensure that the equipment is mounted securely.
» Ensure that seals or sealing materials have not degraded to the point that they no
longer serve the purpose of preventing the ingress of flammable atmospheres
» Replacement parts shall be in accordance with Therma-Stor specifications.
7.3C REPAIRS TO INTRINSICALLY SAFE COMPONENTS
» Do not apply any permanent inductive or capacitance loads to the circuit without
ensuring that this will not exceed the permissible voltage and current permitted for
the equipment in use.
» Intrinsically safe components are the only types that can be worked on while live in
the presence of a flammable atmosphere. The test apparatus shall be at the correct
rating.
» Replace components only with parts specified by Therma-Stor. Other parts may
result in the ignition of refrigerant in the atmosphere from a leak.

HI-E DRY 195 INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS
QUESTCLIMATE.COM(877) 420-1330
» NOTE The use of silicon sealant can inhibit the effectiveness of some types of leak
detection equipment. Intrinsically safe components do not have to be isolated prior
to working on them.
» Check that cabling will not be subject to wear, corrosion, excessive pressure,
vibration, sharp edges or any other adverse environmental effects. The check shall
also take into account the effects of aging or continual vibration from sources such
as compressors or fans.
7.3D DETECTION OF FLAMMABLE REFRIGERANTS
Under no circumstances shall potential sources of ignition be used in the searching for or
detection of refrigerant leaks. A halide torch (or any other detector using a naked flame) shall
not be used.
The following leak detection methods are deemed acceptable for all refrigerant systems.
• Electronic leak detectors may be used to detect refrigerant leaks but, in the case of FLAMMABLE
REFRIGERANTS, the sensitivity may not be adequate, or may need re-calibration. (Detection
equipment shall be calibrated in a refrigerant-free area.) Ensure that the detector is not a potential
source of ignition and is suitable for the refrigerant used. Leak detection equipment shall be set at
25% LFL of the refrigerant and shall be calibrated to 454B.
• Leak detection fluids are also suitable for use with most refrigerants but the use of detergents
containing chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the
copper pipe.
• NOTE: Examples of leak detection fluids are:
» bubble method
» fluorescent method agents.
» If a leak is suspected, all open flames shall be removed/extinguished.
If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be recovered
from the system, or isolated (by means of shut off valves) in a part of the system remote from the leak.
Removal of refrigerant shall be according to Clause DD.9 of 60335-2-40.
7.3E REFRIGERANT REMOVAL AND EVACUATION
When breaking into the refrigerant circuit to make repairs – or for any other purpose – conventional
procedures shall be used. However, for FLAMMABLE REFRIGERANTS it is important that best practice is

6. Compressor terminal C and overload terminal 1: No continuity indicates a defective overload lead.
7. Overload terminals 1 and 3: If there is no continuity, the overload may be tripped; wait 10 minutes and
try again. If there is still no continuity, it is defective and must be replaced.
8. Compressor terminal C and compressor case: Continuity indicates a grounded motor; the compressor
must be replaced.
9. Disconnect the wires from the capacitor. Set the ohmmeter to the Rx1 scale; the capacitor is shorted
and must be replaced if continuity exists across its terminals. If there is no needle movement with the
meter set on the Rx100000 scale, the capacitor is open and must be replaced.
10. Reconnect the wires to the compressor and capacitor; plug in and turn on the unit. If the compressor
fails to start, replace the run capacitor.
7.7B REPLACING A BURNED OUT COMPRESSOR
The refrigerant and oil mixture in a compressor is chemically very stable under normal operating
conditions. However, when an electrical short occurs in the compressor motor, the resulting high
temperature arc causes a portion of the refrigerant oil mixture to break down into carbonaceous sludge,
a very corrosive acid, and water. These contaminants must be carefully removed otherwise even small
residues will attack replacement compressor motors and cause failures.
The following procedure is effective only if the system is monitored after replacing the compressor to
insure that the clean up was complete.
1. This procedure assumes that the previously listed compressor motor circuit tests revealed a shorted or
open winding. If so, cautiously smell the refrigerant from the compressor service port for the acid odor
of a burn out.
WARNING! THE GAS COULD BE TOXIC AND HIGHLY ACIDIC. IF NO ACID ODOR IS
PRESENT, SKIP DOWN TO THE SECTION ON CHANGING A NON-BURN OUT COMPRESSOR.
2. Remove and properly dispose of the system charge. DO NOT vent the refrigerant or allow it to contact
your eyes or skin.
3. Remove the burned out compressor. Use rubber gloves if there is any possibility of coming in contact
with the oil or sludge.
4. To facilitate subsequent steps, determine the type of burn out that occurred. If the discharge line shows
no evidence of sludge and the suction line is also clean or perhaps has some light carbon deposits, the
burn out occurred while the compressor was not rotating. Contaminants are therefore largely confined
to the compressor housing. A single installation of liquid and suction line filter/driers will probably clean
up the system.
If sludge is evident in the discharge line, it will likely be found in the suction line; this indicates the
compressor burned out will running. Sludge and acid have been pumped throughout the system.
Several changes of the liquid and suction filter/driers will probably be necessary to cleanse the system.
5. Correct the system fault that caused the burn out. Consult the factory for advice.
6. Install the replacement compressor with a new capacitor and an oversized liquid line filter.
In a running burn out, install an oversized suction line filter/drier between the accumulator and
compressor. Thoroughly flush the accumulator with refrigerant to remove all trapped sludge and to
prevent the oil hole from becoming plugged. A standing burn out does not require a suction line filter/
drier.
7. Evacuate the system with a good vacuum pump and accurate vacuum gauge. Leave the pump on the
system for at least an hour.
8. Operate the system for a short period of time, monitoring the suction pressure to determine that the
18
HI-E DRY 195 INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS
QUESTCLIMATE.COM(877) 420-1330
suction filter is not becoming plugged. Replace the suction filter/drier if pressure drop occurs. If a
severe running burn out has occurred, several filter/driers may have to be replaced to remove all of
the acid and moisture.
NOTE: NEVER use the compressor to evacuate the system or any part of it.
7.7C REPLACING A COMPRESSOR- NON-BURN OUT
Remove the refrigerant from the system. Replace the compressor and liquid line filter/drier. Charge the
system to 50 PSIG and check for leaks. Remove the charge and weigh in the refrigerant quantity listed
on the nameplate. Operate the system to verify performance.
7.8 RELAY
The contacts of the single pole, single throw relay complete the power circuit to the
compressor. The contacts are closed when power is provided to the relay coil via the control
circuit. The control circuit includes the humidity control, low pressure control, defrost
thermostat and timer.
7.9 HUMIDITY CONTROL
The humidity control is a digital setting that controls the dehumidifier when the relative
humidity of the air in which it is located rises to the dial set point. It opens when the RH
drops 3% below the set point.
7.10 DEFROST THERMISTOR
The defrost thermistor is attached to the refrigerant suction tube between the accumulator and
compressor. If the low side refrigerant temperature drops due to excessive frost formation on the
evaporator coil, the thermostat opens. The compressor is then cycled off and on by the defrost timer.
The blower will continue to run, causing air to flow through the evaporator coil and melt the ice when
the compressor is off. When the air temperature and/or humidity increase, the evaporator temperature
will rise and the thermostat will close to end the defrost cycle.
7.11 CONDENSATE PUMP
Condensate is automatically pumped when the water level in the pump’s reservoir rises to close the float
switch.
If the pump is unable to empty its reservoir due to a pump failure or blocked condensate hose, a pump
safety float switch is triggered before the reservoir overflows. The switch turns off the compressor via
its relay.
To replace the condensate pump:
1. Unplug the unit & remove the front cover.
2. Disconnect the 2 hoses from the pump.
3. Disconnect pump lead wires to the electrical box.
4. Remove the wingnut from the pump bracket.
5. Install new pump and bracket.
6. Connect the new pump wiring.
7. Connect the hoses to the new pump. Carefully route the hoses so they do not contact the copper
refrigerant lines or the compressor shell.

prior to re-use of recovered refrigerant. It is essential that electrical power is available before the task
commences.
1. Become familiar with the equipment and its operation.
2. Isolate system electrically.
3. Before attempting the procedure, ensure that:
» mechanical handling equipment is available, if required, for handling refrigerant cylinders;
» all personal protective equipment is available and being used correctly;
» the recovery process is supervised at all times by a competent person;
» recovery equipment and cylinders conform to the appropriate standards.
4. Pump down refrigerant system, if possible.
5. If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of
the system.
6. Make sure that cylinder is situated on the scales before recovery takes place.
7. Start the recovery machine and operate in accordance with instructions.
8. Do not overfill cylinders (no more than 80 % volume liquid charge).
9. Do not exceed the maximum working pressure of the cylinder, even temporarily.
10. When the cylinders have been filled correctly and the process completed, make sure that the cylinders
and the equipment are removed from site promptly and all isolation valves on the equipment are
closed off.
11. Recovered refrigerant shall not be charged into another REFRIGERATING SYSTEM unless it has been
cleaned and checked.
9.1 LABELLING DECOMMISSION MACHINES
Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The label
shall be dated and signed. For appliances containing FLAMMABLE REFRIGERANTS, ensure that there are
labels on the equipment stating the equipment contains FLAMMABLE REFRIGERANT.
9.2 REFRIGERANT RECOVERY
When removing refrigerant from a system, either for servicing or decommissioning, it is recommended
good practice that all refrigerants are removed safely.
When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders
are employed. Ensure that the correct number of cylinders for holding the total system charge is available.
All cylinders to be used are designated for the recovered refrigerant and labelled for that refrigerant (i.e.
special cylinders for the recovery of refrigerant). Cylinders shall be complete with pressure-relief valve and
associated shut-off valves in good working order. Empty recovery cylinders are evacuated and, if possible,
cooled before recovery occurs.
