General Information
Inspection
Upon receipt of the equipment, carefully check the
shipment against the bill of lading. Make sure all units
have been received. Inspect the carton or crating of
each unit, and inspect each unit for damage. Assure
the carrier makes proper notation of any shortages or
damage on all copies of the freight bill and completes a
common carrier inspection report. Concealed damage
not discovered during unloading must be reported to the
carrier within 15 days of receipt of shipment. If not filed
within 15 days, the freight company can deny the
claim without recourse. Note: It is the responsibility
of the purchaser to file all necessary claims with the
carrier. Notify the ClimateMaster Traffic Department of
all damage within fifteen (15) days of shipment.
Storage
Equipment should be stored in its shipping carton in a
clean, dry area. Store units in an upright position at all
times. Stack units a maximum of 3 units high.
Unit Protection
Cover units on the job site with either shipping cartons,
vinyl film, or an equivalent protective covering. Cap
the open ends of pipes stored on the job site. In areas
where painting, plastering, and/or spraying has not
been completed, all due precautions must be taken to
avoid physical damage to the units and contamination
by foreign material. Physical damage and contamination
may prevent proper start-up and may result in costly
equipment clean-up.
Examine all pipes, fittings, and valves before installing
any of the system components. Remove any dirt or trash
found in or on these components.
Pre-Installation
Installation, Operation, and Maintenance instructions are
provided with each unit. GL Series horizontal equipment
is designed for installation above false ceiling or in
a ceiling plenum. The installation site chosen should
include adequate service clearance around the unit.
Before unit start-up, read all manuals and become
familiar with the unit and its operation. Thoroughly check
the system before operation.
Prepare units for installation as follows:
1. Compare the electrical data on the unit nameplate
with ordering and shipping information to verify that
the correct unit has been shipped.
2. Keep the cabinet covered with the shipping carton
until installation is complete and all plastering,
painting, etc. is finished.
3. Verify refrigerant tubing is free of kinks or dents and
that it does not touch other unit components.
4. Inspect all electrical connections. Connections must
be clean and tight at the terminals.
5. Remove any blower support packaging from mouth
of blower.
6. Loosen compressor bolts on units equipped with
compressor spring vibration isolation until the
compressor rides freely on the springs. Remove
shipping restraints.
7. Locate and verify any hanger, or other accessory kit
located in the compressor section and or the
blower section.
DO NOT store or install units in corrosive environments or
in locations subject to temperature or humidity extremes
(e.g., attics, garages, rooftops, etc.) Corrosive conditions
and high temperature or humidity can significantly reduce
performance, reliability, and service life. Always move units
in an upright position. Tilting units on their sides may
cause equipment damage.
To avoid equipment damage, DO NOT use these units
as a source of heating or cooling during the construction
process. The mechanical components and filters used in
these units will quickly become clogged with construction
dirt and debris which may cause system damage.
To avoid the release of refrigerant into the atmosphere,
the refrigerant circuit of this unit must be serviced only by
technicians who meet local, state, and federal proficiency
requirements.
All refrigerant discharged from this unit must be recovered
WITHOUT EXCEPTION. Technicians must follow industry
accepted guidelines and all local, state, and federal
statutes for the recovery and disposal of refrigerants.
If a compressor is removed from this unit, system
refrigerant circuit oil will remain in the compressor. To
avoid leakage of compressor oil, the refrigerant lines of the
compressor must be sealed after it is removed.

GL Horizontal Unit Location
GL units are NOT designed for outdoor installation.
Locate the unit in an INDOOR area that allows enough
space for installation and for service personnel to perform
typical maintenance or repairs without removing from the
ceiling. Horizontal units are typically installed above a
false ceiling or in a ceiling plenum. Refer to Figure 3a for
an illustration of a typical installation.
Conform to the following guidelines when selecting
unit location:
1. Provide a hinged access door in concealed-spline or
plaster ceilings. Provide removable ceiling tiles in t-bar
or lay-in ceilings. Refer to physical dimensions page
or submittal drawing for horizontal unit dimensions.
Size the access opening to accommodate the service
technician during the removal or replacement of the
compressor and the removal or installation of the unit
itself.
2. Provide access to hangar brackets, water valves
and fittings. Provide screwdriver clearance to access
panels, discharge collars and all electrical connections.
3. DO NOT obstruct the space beneath the unit with
piping, electrical cables and other items that
prohibit future removal of components or the
unit itself.
4. Use a manual portable jack/lift to lift and support the
weight of the unit during installation and servicing.
The installation of water source heat pump units and
all associated components, parts and accessories
which make up the installation shall be in accordance
with the regulations of ALL authorities having
jurisdiction and MUST conform to all applicable codes.
It is the responsibility of the Installing Contractor to
determine and comply with ALL applicable codes and
regulations.
Locate the unit in an indoor area that allows easy removal
of the filter and access panels, and has enough space
for service personnel to perform maintenance or repair.
Provide sufficient room to make water, electrical, and duct
connection(s). If the unit is located in a confined space
provisions must be made for return air to freely enter
the space by means of a louvered door, etc. Any access
panel screws that would be difficult to remove after the
unit is installed should be removed prior to setting the
unit. These units are not approved for outdoor installation
and, therefore, must be installed inside the structure
being conditioned. Do not locate in areas where ambient
conditions are not maintained within 40-100°F [4-38°C]
and up to 75% relative humidity.

4. Provide access to water valves and fittings, and
screwdriver access to the unit side panels, discharge
collar and all electrical connections
Figure 2b: Typical Vertical Installation
Duct System Design & Installation Guidelines
The following application guidelines must be used when
installing GLH and GLV units. Failure to follow these
guidelines could result in unsatisfactory unit performance
and/or premature failure of some unit components.
ClimateMaster will not warrant, or accept responsibility
for products which fail, have defects, damage or
insufficient performance as a result of improper
application.
•The duct system must be sized to handle the
airflow quietly and must not exceed the maximum
allowable External Static Pressure. To maximize
sound attenuation metal supply and return ducts
should include internal insulation or be of duct board
construction for the first few feet.
•Install a flexible connector in all supply and return
air ducts close to the unit to inhibit sound transfer to
the ducts.
•Do not install uninsulated duct in an unconditioned
space. The unit performance will be adversely
affected and damage from condensate can occur.
•On units with multiple fan outlets a “pair of pants”
duct connection must be used for proper air balance
and distribution and to prevent fan oscillation.

•Include at least one 90-degree turn in supply air
ducts to reduce noise transmission.
•Existing ducts must be checked to insure proper
size and configuration prior to installation of any
replacement unit. Also inspect for and repair all air
leaks in existing ducts.
•Units may only be connected to a dedicated duct
system. Consult the factory BEFORE connecting
multiple units to a common duct system.
•Never connect a unit to a duct system with
automatic or modulating dampers, VAV boxes, etc.
in the supply air system. Never allow a situation
where the total unit CFM can drop below the
minimum required for proper unit operation.
Installation
•Never connect a bypass damper from the supply air
duct to the return air duct. Never allow the return air
temperature to drop below the minimum allowable
normal temperature for proper unit operation.
•Do not use GLH or GLV units for 100% outdoor air
treatment. Do not add hot-gas-bypass to “convert”
a unit for outdoor air treatment. Always use a
dedicated outdoor air unit for outdoor air treatment.
•Do not exceed 10% of the total unit CFM with
untreated outdoor air.

Installation of Supply and Return Piping
Follow these piping guidelines.
1. Install a drain valve at the base of each supply and
return riser to facilitate system flushing.
2. Install shut-off / balancing valves and unions at each
unit to permit unit removal for servicing.
3. Place strainers at the inlet of each system
circulating pump.
4. Select the proper hose length to allow slack between
connection points. Hoses may vary in length by +2%
to -4% under pressure.
5. Refer to Table 1. Do not exceed the minimum bend
radius for the hose selected. Exceeding the minimum
bend radius may cause the hose to collapse which
reduces water flow rate. Install an angle adapter to
avoid sharp bends in the hose when the radius falls
below the required minimum.
Insulation is not required on loop water piping except
where the piping runs through unheated areas or outside
the building or when the loop water temperature is below
the minimum expected dew point of the pipe ambient.
Insulation is required if loop water temperature drops
below the dew point.
Pipe joint compound is not necessary when Teflon
threaded tape is pre-applied to hose assemblies or when
flared-end connections are used. If pipe joint compound
is preferred, use compound only in small amounts on the
male pipe threads of the fitting adapters. Prevent sealant
from reaching the flared surfaces of the joint.
Table 1: Metal Hose Minimum Bend Radii
Figure 3: Supply/Return Hose Kit
Piping Installation
Note: When anti-freeze is used in the loop, assure
that it is compatible with Teflon tape or pipe joint
compound employed.
Maximum allowable torque for brass fittings is 30 foot-
pounds [41 N-m]. If a torque wrench is not available,
tighten finger-tight plus one quarter turn. Tighten steel
fittings as necessary.
Optional pressure-rated hose assemblies designed
specifically for use with ClimateMaster units are available.
Similar hoses can be obtained from alternate suppliers.
Supply and return hoses are fitted with swivel-joint
fittings at one end to prevent kinking during installation.
Refer to Figure 3 for an illustration of a Supply/Return
Hose Kit. External Pipe Thread (EPT) adapters secure
hose assemblies to the unit and risers. Install hose
assemblies properly and check them regularly to avoid
system failure and reduced service life.

Condensate Piping
Units are typically installed directly above each other on
successive floors with condensate drains located near
the units.
Pitch the unit toward the drain as shown in Figure 4a to
improve the condensate drainage. Ensure that unit pitch
does not cause condensate leaks inside the cabinet.
Install condensate trap at each unit with the top of
the trap positioned below the unit condensate drain
connection.
Figure 4b illustrates a typical trap and vent used with GL
series equipment. Design the depth of the trap (water-
seal) based upon the amount of ESP capability of the
blower (where 2 inch [51mm] of ESP capability requires 2
inches [51mm] of trap depth). As a general rule 1.5 inch
[38mm] trap depth is a minimum trap depth.
Each unit must be installed with its own individual trap
and connection to the condensate line (main) or riser.
Provide a means to flush or blow out the condensate line.
DO NOT install units with a common trap and or vent.
Always vent the condensate line when dirt or air
can collect in the line or a long horizontal drain line
is required. Also vent when large units are working
against higher external static pressure than other units
connected to the same condensate main since this may
cause poor drainage for all units on the line. WHEN A
VENT IS INSTALLED IN THE DRAIN LINE, IT MUST BE
LOCATED AFTER THE TRAP IN THE DIRECTION OF
THE CONDENSATE FLOW.

Water-Loop Heat Pump Applications
Commercial systems typically include a number of
units plumbed to a common piping system. Any unit
plumbing maintenance work can introduce air into the
piping system, therefore air elimination equipment is
a major portion of the mechanical room plumbing. In
piping systems expected to utilize water temperatures
below 50°F [10°C], 1/2" [13mm] closed cell insulation is
required on all piping surfaces to eliminate condensation.
Metal to plastic threaded joints should never be
employed due to their tendency to leak over time. All
non-distributor class units include a low temperature-
soldered bracket-supported FPT water connection.
Teflon tape thread sealant is recommended to minimize
internal fouling of the heat exchanger. Do not overtighten
connections and route piping so as not to interfere with
service or maintenance access. Hose kits are available
from ClimateMaster in different configurations as shown
in Figure 5 for connection between the GL Series
and the piping system. The hose kits include shut off
valves, P/T plugs for performance measurement, high
pressure stainless steel braid hose, "Y" type strainer
with blowdown valve, and "J" type swivel connection.
Balancing valves to facilitate the balancing of the
system, and an external low pressure drop solenoid
valve for use in variable speed pumping systems, may
also be included in the hose kit. The piping system
should be flushed to remove dirt, piping chips, and other
foreign material prior to operation. See Piping System
Cleaning and Flushing Procedures. The flow rate is
usually set between 2.25 and 3.5 gpm per ton [2.9 l/m
and 4.5 l/m per kW] of cooling capacity. ClimateMaster
recommends 2.5 gpm per ton [3.2 l/m per kW] for most
applications of water loop heat pumps. To insure proper
maintenance and servicing, P/T ports are imperative for
temperature and flow verification, as well as performance
checks.
Cooling Tower/Boiler Systems typically utilize a
common loop maintained 60-90°F [16-32°C]. The use
of a closed circuit evaporative cooling tower with a
secondary heat exchanger between the tower and the
water loop is recommended. If an open type cooling
tower is used continuously, chemical treatment and
filtering will be necessary.
Low Water Temperature Cutout Setting
CXM or DXM Control:
When an antifreeze is selected, the FP1 jumper (JW3)
should be clipped to select the low temperature
(Antifreeze 13°F [-10.6°C]) setpoint to avoid nuisance
faults. See Low Water Temperature Cutout Selection.
NOTE THAT THE EXTENDED RANGE OPTION SHOULD
BE SELECTED WHEN LOOP CONDITIONS ARE
EXPECTED TO DROP BELOW 60°F [16°C].
