MAINTENANCE & SERVICE
MAINTENANCE OVERVIEW
Your ICE AIR WSHP unit is designed to provide you with many years
of efficient, trouble-free comfort conditioning service. To ensure
equipment longevity and efficiency, please make sure that the
following simple maintenance procedures are followed.
This manual assumes that your WSHP unit has been installed by a
qualified installation professional, and is operating properly prior to
maintenance service.
• Have your unit periodically inspected by a properly trained
service professional or building maintenance staff person. The
unit should be checked for the safe and proper functioning of
all of its systems at least once a year. The following recom-
mended maintenance procedures should be carried out only by
trained personnel with strict adherence to the safety guidelines
outlined at the beginning of this manual. These procedures
MUST be followed to ensure your safety and the safety of the
person maintaining the equipment.
FILTER
ICE AIR WSHPs are equipped with a washable/reusable Filter.
It is recommended that you clean the indoor air filter after
every 350 to 400 hours of unit operation - more frequently
if the unit is running in an environment of high dust, pet
dander or other pollutants in the indoor atmosphere.
• Filter inspection: The filter is located at the bottom of your unit.
To remove unit slide it out towards you.
• To reinstall place filter under the unit and slide back in to the
filter rack
Filter Cleaning:
To clean your filter use luke warm water with a biodegradable
cleaner rinse and allow to dry completely before installing back
to unit. (As an alternate cleaning method,
the filter may be cleaned on both sides
using a vacuum cleaner with a soft brush
type attachment.)
DO NOT OPERATE UNIT WITHOUT
FILTERS. This practice will damage and/
or seriously impair the performance of
your unit and could void your Warranty.
CHASSIS CLEANING
Evaporator Coil and Drain Pan/Drain Hoses:
To access the components within the chassis of the unit,
disconnect unit power and then remove the unit Access Door
by unscrewing the retaining screws that hold the door in place
(use a Phillips head driver). You will then have access to the
unit chassis and components:
CAUTION: to prevent injury or death due to electrical shock or contact with moving part,
turn off the disconnect switch before servicing this unit.
IMPORTANT NOTE: It is not the intent of this maintenance manual to correct any installation deficiencies. If you have any
doubt about the proper initial installation (or reinstallation after servicing) of your WSHP unit(s)- noisy or inefficient unit
operation,frayed or damaged electrical connections, improper unit appearance, etc. Please contact a trained servicer or building
maintenance staff immediately.
DO NOT OPERATE ANY EQUIPMENT THAT DOES NOT APPEAR TO BE FUNCTIONING PROPERLY!
IMPORTANT NOTE:
The power MUST be disconnected before carrying
out any of the following cleaning!

OPERATING & MAINTENANCE MANUAL – VERTICAL STACK WATER SOURCE HEAT PUMP (VWSHP)
Compressor:
Annual check should be performed to detect potential
problems.
• Amperagedrawshouldnotexceednormalfullloadampsindicated
in the performance table. (Consult installation manual for details).
Heat Exchanger:
Water coil maintenance is not required. If the unit installation is
located in a system with water problem history it is best to
establish a periodic maintenance program. It is the building’s
responsibility to maintain a water system that should provide
your unit with treated and filtered water to keep water
flowing freely thru your equipment. Generally if the water
flow exceeds 3 gpm per ton the water velocities should keep
your coil free of scaling and debris that could lead to coil
erosion and fouling up.
General Unit Inspection:
Visually inspect unit at least once a month. Pay special attention to
hose assemblies and connections. Repair any leaks and replace
deteriorated hose immediately to avoid potential costly damage to
your property due to component failure.
Evaporator Coil:
Check the coil for cleanliness and uniformity of fins. If the coil
is dirty, vacuum clean with a soft brush attachment. This is the
only form of cleaning that should be carried out within an
apartment. If the coil requires additional cleaning, the unit
must be removed from the wall cabinet and cleaned using
compressed air and / or washed. These operations MUST be
carried out in a facility properly equipped to handle this type of
work in a safe and professional manner. Do not carry out this
cleaning in a finished apartment or office area.
Drain Pan/Drain Hose Cleaning:
The condensate pan is located under the unit chassis. Check
the visible section of the interior of the drain pan for any
buildup of dirt or condensate water.
Wash annually to remove all dirt build-up. Check condensate
drain pan for algae growth every 2 to 3 months. If algae growth
is apparent consult a water treatment specialist for treatment.
Drain Hose:
Check drain hose for leaks and blockage to eliminate potential
problems.
Evaporator Motor and Blower Assembly:
If there is evidence of dirt or dust build-up the evaporator
motor or blowers, they should be cleaned either by vacuum
cleaning (if working in an apartment) or by removing the unit to
a workshop location and cleaning with compressed air. Always
obey safety guidelines for using compressed air in this latter
case. Your ICE AIR WSHP has permanently lubricated motor
bearings that do not require additional lubrication. Blowers and
motor are factory assembled for quiet performance – if there is
any excessive noise and vibration from this assembly, it should
be serviced by a qualified technician.
